Description:
FIELD OF THE INVENTION 
       [0001]    Described here are systems, devices, and methods for use in the field of waste water recycling. More specifically, described here are and systems and methods that may be used to a treatment, expandable collection, storage system used in the recycling of household and commercial building waste water. 
       BACKGROUND OF THE INVENTION 
       [0002]    According to recent reports in approximately 25 years, fresh water may become very scarce. After three years of research, the entire world&#39;s population may go thirsty by 2040 and remarkably by 2020, 40 percent of the world&#39;s population could be adversely affected by global water shortages. 
         [0003]    Within an ever growing population is the ongoing demand for commercial goods in which requires water for manufacturing. This industrial practice particularly in time of drought and with the ongoing global pollution of lakes, rivers and oceans only continues to aggravate the potentials for looming shortages. 
         [0004]    According to the Environmental Protection Agency, (EPA) the average American family uses approximately 320 gallons of water per day, of which about 30 percent is devoted to outdoor uses. More than half is used for watering lawns and gardens and where nationwide, landscape irrigation is estimated to account for nearly one-third of all residential water use, totaling nearly 9 billion gallons per day. 
         [0005]    Therefore, being presented is a method and apparatus capable of implementation into any structure to perform water conservation through recycling. Most building structures typically provide a water entry source as well as a waste water exit. Water entry and exit is dependent upon a series of pipes commonly referred to as plumbing and where upon installation, is regulated under specific aspects of building codes. Building codes are referred to by building inspectors to insure a quality of construction and whereby, plumbing codes are written by the International Association of Plumbing and Mechanical Officials, (IAPMO). 
         [0006]    Within plumbing codes IAPMO refers to three different types of water associated with construction; potable, grey and black water. During construction, potable water rates the highest in priority in regards to safe delivery and whereas household waste water commonly referred to as greywater, is generated daily by households while doing chores such as, washing dishes, clothes, brushing teeth, taking baths, showers, or any water utilized in which is not directly related to toilets or urinals. The third water classification is considered blackwater which is generated and directed into the sewer system after flushing toilets or urinals. 
         [0007]    In most cases, both grey and black water exits the structure together and is directed flow into municipal sewer lines or where in rural areas, into septic tanks for treatment. Typically all waste water exiting methods are reliant upon gravity fall through piping in order to reach its final destination. 
         [0008]    The present invention provides a method and apparatus whereas up to fifty percent of the greywater generated by a typically households can be recycled and reused for outdoor irrigation, or in some cases it can be diverted back into the structure to replenish toilet tanks after flushing. Over the years a wide variety of methods have been developed to perform greywater treatment and recycling, as an example, U.S. CA 2759407/Green, demonstrates a “Grey Water Recycle System” is comprised of a pump unit that installs to the bathtubs overflow valve that siphons and the waste water and redirects it to the toilets tank. Another unit in the system replaces the sink trap and also redirects waste water to the toilet tank. Another unit is at the point of the water shutoff for the toilet. This selector valve unit is the intake for the system that senses if the toilet tank is empty and thus accepts the greywater flow or rejects it (and/or communicates this information to the other units). This unit also allows for the user to fill the tank from the city water feed if no grey water is available. Another unit is at the counter sink u-joint which redirects sink greywater to the system intake selector valve. Standard and custom piping is used for existing bathrooms as well as custom built models. 
         [0009]    Basically Green&#39;s invention relies on a siphon pump attached to the bathtub overflow to redirect bathtub greywater to the toilet tank. 
         [0010]    U.S. Patent WO 2005056935 B1/Oekroes, demonstrates a method for greywater reusing system for the reuse of household greywater from washing to flush the toilet, consisting of a greywater tank built on top of a front loader washer equipped with a stronger primary water pump and a possibly a secondary water pump controlled by the electronic central unit in harmony with the water sensors. The characteristic feature of the invention is that the automatically operating mechanical flushing system can be used independently, or together with the electronic flushing system operated by the electronic control unit of the washer in harmony with the water sensors, valves and pump(s). 
         [0011]    Oekroes invention relies on a system where greywater recycling involves a washing machine together with an incorporated greywater tank, for the economical flushing of toilets, consisting of a combined grey water tank is built together in one single body unit with a washing machine provided. 
         [0012]    Another example of a greywater recycling system is CA 2771600 A1 titled “Electronic grey water recycling system”/Ryan, this device is an electronic grey water recycling system designed for residential application. The unit would typically be installed in a basement located near a washing machine and/or hot water tank. The City Water OUT line can be used to supply a hot water tank with relatively warmer water due to the heat recovered from the grey water captured in the tank from showers, washing machines, etc. 
         [0013]    The system is designed to minimize regular maintenance—such as cleaning filters—by incorporating an automated back flush cycle, which is triggered when the water level reaches the high water level mark. Ryan relies on an ultrasonic method for cleaning during the back flush cycle. 
         [0014]    In application WO 2014029989 A1, titled: “Waste Water Recycling” by Holdsworth, Murray and Pearson disclose the method for capturing, storing and supplying cleaned grey water to a first reservoir for greywater, a second reservoir for cleaned greywater and an outlet for supply of cleaned greywater. The system being configured such that the inlet feeds the first reservoir, the first reservoir feeds the second reservoir and the second reservoir feeds the outlet. Wherein the first and second reservoirs are fluidly connected via a valve configured to allow fluid flow from the first reservoir to the second reservoir but not from the second reservoir to the first reservoir. Such an arrangement allows a head of cleaned greywater to build up in the second reservoir, e.g. to service multiple flushes of a toilet connected to the outlet. Moreover, when there is a greater head in the second reservoir than in the first reservoir, any turbulent water in the first reservoir (typically caused by grey water entering that reservoir) will not be able to enter—and disturb—the water in the second reservoir, resulting in cleaner water from the outlet supplied from the second reservoir. To the extent that potable water is supplied to top up the second reservoir (e.g. in the event of insufficient greywater input), the valve prevents that potable water from flowing into the first reservoir, thereby reducing the amount of potable water required. 
         [0015]    Most of the publications described above would likely not pass IAPMO, UL or the Nation Sanitation Foundation, (NSF) standards for approved materials, consumer safety, or receive certification for meeting and maintaining water assurance standards as set forth by plumbing code number IGC 324-2015, a reference for; “Alternate Water Source Systems”. IGC 324 code specifies specific requirements in regards to material types, physical characteristics, performance and electrical safety and in maintaining and delivering a specific water quality in which would meet EPA&#39;s standards for environmental release. 
         [0016]    However, if any of the publications described above do meet the criteria of IGC 324, the water quality then would only be acceptable for subsurface drip irrigation and not for surface release or the replenishment of toilet tanks. See the reference at http://www.iapmo.org/Pages/GetCertified.aspx. 
         [0017]    In California some cities due to drought initiatives have mandated the recycling of greywater in order to meet their water conservation efforts. Statewide water conservation was implemented by various State agencies in hopes of conserving approximately twenty five percent of the State&#39;s annual usage. 
         [0018]    However, building codes in regards to greywater recycling technologies and installation were slow to evolve and are now just making their way into written codes. These codes provide building inspectors with installation mandates and whether a collection, treatment and storage system has achieved certification recognition “for public use”. Therefore, the object of the present invention is to provide a sanction approved water conservation apparatus based on written codes in which can be implemented by most households or commercial building operators, particularly since fifty two percent of the U. S. at the time of this writing is considered in drought. 
         [0019]    All potable water which eventually becomes greywater may vary due to EPA&#39;s acceptable levels for turbidly, total dissolved solids, (TDS) biological oxygen demand, (BOD) chemical oxygen demand, (COD) and other organics commonly found or added to the water. Potable water will always vary in quality due to contaminate types, mineral content, geographic origin or by chemicals utilized during a treatment process to achieve a potable status. Therefore, various greywater treatment methods may be required or excised within a greywater recycling apparatus in order to meet prescribed water quality standards as set forth by various State and Federal agencies in regards to environmental release standards. 
         [0020]    In response to some of the aforementioned methods and systems utilized in the treatment, storage and redistribution of greywater from residential or commercial structures will be addressed by the fields of this present invention. 
       SUMMARY OF THE INVENTION 
       [0021]    The present invention of the greywater recycling system can work as a secondary plumbing system commonly installed inside a structure of the building to identify and isolate greywater from the blackwater. 
         [0022]    The present invention further provides an expandability feature in regards to reservoir storage. In large metropolitan areas property configurations, lot sizes or the property line distance between homes which sometimes can only be a few of feet often limits installation location or the catch basin&#39;s storage capacity. 
         [0023]    Due to space limitations or property configurations the subterranean catch basin can be expanded in length or width increasing the present invention&#39;s storage capacity by the acceptance of a secondary reservoir where storage capacity is often dictated by landscape square footage or how often the landscaping requires irrigation. 
         [0024]    Further, building codes often dictate installation setback from the structure&#39;s foundation or from adjacent property lines. These setback regulations relate to the distance away from the structure or from a property line where the greywater system can be installed. Building codes typically state in regards to bury objects such as a tank, for every inch of depth relates to the amount of setback inches required away from the structure&#39;s foundation. As for example, if an object having a twenty inch depth is buried, then it requires a twenty inch setback from the foundation. Therefore, the present invention&#39;s frontal area and depth tapers back away from the structure and back towards the reservoir allowing installation to be performed closer to the structure&#39;s foundation. The present invention designates this tapering section as a dry area which provides housing for electrical components as well as for the series of media housing filtration system  550 . 
         [0025]    The present invention further provides the option of working in conjunction with an optional ultrafine filtration or RIO system and whereas, these ultrafine systems should be considered as nano or ultra-micron membrane systems. These systems are used to produce an exceptional water quality, such as when using nano membranes during reverse osmosis, (RIO) for potable water applications. 
         [0026]    Unfortunately, most homes and commercial building are already equipped with surface irrigation, (sprinkler) systems in which due to EPA&#39;s water quality requirements for spray, (surface) irrigation, the catch basin&#39;s filtration systems does not meet the EPA&#39;s standards for spray irrigation. Therefore, the catch basin would have to work in conjunction with an ultra-fine filtration system in order to produce and maintain the standards for surface release. 
         [0027]    Under IGC 324 there is an allowance for surface spray but only if the catch basin works in conjunction with an ultrafine filtration system accompanied by flow through a ultra-violet light, (UV). Further if the catch basin system works in conjunction with the ultrafine filtration and UV system then the treated greywater can be returned back inside the structure and used to replenish toilet tanks. 
         [0028]    However, in some irrigation applications and due to daily household greywater generation, a complete catch basin, ultrafine filtration and UV system may not satisfy a full spray irrigation cycle. This presents irrigation inadequate&#39;s for the home owner as well as to commercial building operators. 
         [0029]    According to most Public Health Departments, the commingling of treated greywater with potable or municipal water is not allowed. To overcome the irrigation cycle problem, make up water from an additional source such as municipal may be used but only when taking the proper precautions to prevent cross contamination due to water commingling contact. 
         [0030]    An approved method in preventing cross contamination is a method commonly known by the plumbing industry as an “air gap”. An air gap is simply an atmospheric opening existing between the two types of waters. An air gap according to the plumbing industry is an unobstructed vertical space between a water inlet and the flood level of a fixture. 
         [0031]    In the case of the present invention, an air gap method can be implemented and maintained inside the storage reservoir between a municipal water inlet and the prescribed grey water full point. The air gap method allows maintaining enough water inside the reservoir at all times to complete the irrigation task. 
         [0032]    To prevent over flowing the reservoir with municipal water an electric shut off valve connected to the municipal water inlet can be utilized with the electric valve closing or opening triggered by the water level sensor. Optimally, if the level sensor were to reach its predetermined low setting it would open the valve allowing an inflow of municipal water and whereas, once reaching a predetermined high level and before closing up the air gap, the level sensor would trigger the valve to close. 
         [0033]    In response to some of the aforementioned methods and systems used in the treatment and transfer of grey water for recycling will be addressed by the fields of the present invention. These, other features and advantages may be incorporated into certain embodiments of the invention which will become more fully apparent from the following description and appended claims. However, due to redundancy of multiples of sinks, toilets, bathtubs and showers, the present invention explanation should be interpreted as “a series of” unless otherwise noted. Therefore and once explained, the present invention should not require that all the advantageous and features be described herein or be incorporated into every embodiment of the invention.

     DETAILED DESCRIPTION 
       [0040]    Described here are systems, methods, greywater recycling devices, and positioning components that can be used in the greywater recycling. Further, methods for making greywater recycling are described. 
         [0041]      FIG. 1  illustrates a flow diagram of a conventional home or commercial building where greywater can be accepted and treated for recycling. Within building codes are for three different of water classifications associated with structural plumbing; potable, grey and blackwater. Within these codes are regulations governing greywater recycling systems and where only selected greywater sources can be utilized for collection and recycling. In other words, within homes and commercial buildings are greywater sources that according to plumbing codes are not suitable for collection. These sources include greywater coming from kitchen sinks, garage disposes and dishwashers. This is mainly due to food contamination contributing to bacteria, virus accumulation and growth. Greywater contributed by these sources are directed flow into the sewer system along with blackwater obtained from toilet or urinal flushing. 
         [0042]      FIG. 1  illustrates a conventional recycling system  100 . The individual bathroom section having blackwater generated by a toilet  2  in which when flushed is directed flow into a dedicated sewer line  4 . The blackwater once exiting sewer line  4  flows into a master sewer pipe  6  having connection to the main sewer system. The greywater coming from either of the washing machine  5 , the Bathroom sink  8 , bathtub or shower  10  can be plumbed with secondary piping more commonly referred to as purple piping,  12  and  14  which collects and directs greywater flow towards purple master collection pipe  16 . 
         [0043]    Master collection pipe  16  receives greywater from the various approved sources and directs flow under gravity influence into a subterranean catch basin  18 . The subterranean catch basin  18  of the conventional system  100  is usually buried below ground level to accept a gravity fall rate in the deliverance of greywater from the structure as opposed to utilizing an electric pump for delivery. 
         [0044]    During installation the hole dug for the subterranean catch basin system  18  is organized such that the removal lids sit flush with ground level. However, in situations where a concrete slab floor may be planned for new construction or where the greywater system is planned as a retro-fit system to an older structure utilizing a slab floor, it may require the catch basin  18  to be buried deeper in the ground in order to receive an ampule gravity flow. Slab floors in general often hinder and prevent an ample flow due to existing sewer pipe poured in concrete during construction sit within or just below the slab. In these cases, the catch basin  18  of the conventional system may require a deeper burial rate in order to achieve ampule gravity flow. If the catch basin  18  requires a lower burial rate an extension ring  11  having the same outside dimensions as the catch basin housing  18  and lid  9  can be installed around the outer perimeters where the lid  9  normally would install. Once the ring  11  is installed it makes provisions to accept and mount the lid  9 . The extension ring  11  is used to elevate the lid to the surrounding ground level and provides a series of vertical through holes used to retain bolts required for lid  9  and extension ring  11  installation to the catch basin  18 . 
         [0045]    Under current building codes the lid  9  of the catch basin system  18  must be colored in purple for greywater identification and further, it is permanently marked listing a series of safety precautions. These precautions include having the manufacture name, the maximum influent capacity, “Gray Water”, “Danger” and “Unsafe Water” and in addition, the lid  9  must be capable of sustaining a weight bearing load of approximately three hundred pounds or better. 
         [0046]    As shown in  FIG. 1 , the conventional recycling system  100  has disadvantages for greywater recycling because the catch basin  18  can be overwhelmed too fast or with too much influent flow when the influent is provided out flow passage from the catch basin  18  through an attached back flow preventer valve,  20 . Backflow is a term used in plumbing for the unwanted flow of water in a reverse direction. Sewer contamination can be of a serious health risk if allowing sewer constituents entry into a water supply. For this reason, building codes mandate a series of measures and backflow prevention devices to prevent sewage backflow and therefore, the back flow preventer valve  20  location must allow a connection between the catch basin  18  and sewer line  6  in order to prevent a back flow of sewage from entering into the catch basin housing  18 . However, the conventional recycling system  100  usually cannot solve the backflow problems described above. 
         [0047]      FIG. 2  illustrates the current invention of the graywater recycling system  200 , with a schematic flow diagram pertaining to influent treatment, storage and distribution. The greywater recycling system  200  is comprised of a pre-filtration system  250 , a reservoir&#39;s storage system  350 , a media housing filtration system  550 , and an ultra-filtration system  450 . 
         [0048]    The influent  16  first enters into the pre-filtration system  250  which is composed of an open-ended manifold  54  incorporating a series of descending exit openings  24 . These descending exit openings  24  also contain a series of attached pre-filters  26 . The pre-filters  26  can be micron-sized, between fifty to hundred microns. These pre-filters  26  can be applied to withhold and remove household solids such as hair, food particles or washing machine lint before the greywater enters into the reservoir&#39;s storage system  350 . The pre-filters  26  can be removed and reversed flushable to allow the consumer to remove the pre-filters  26  periodically for inspection, cleaning or replacement. The number of the descending exit openings  24  can be single or plural and expandable based on the needs of the users. 
         [0049]    In  FIG. 2 , once the inflow of greywater influent  16  has completed the pre-filtration system  250 , but while still under gravity influence, the influent  16  is then allowed migration into the reservoir&#39;s storage system  350 . On the side wall of the reservoir system  350 , a water level sensor  15  is incorporated and utilized to prevent the reservoir&#39;s storage system  350  from overflowing. Once the water reaches a predetermined height, the sensor  15  electrically activates a submerged transfer pump  30  mounted down inside the reservoir system  350 . The pump  30  is utilized to transfer the pre-filtered influent  32  into a series of individual housings of the housing system  550  containing known filtration media  330  such as, activated carbon, green sand, clays, deamacious earth, kinetic degradation flux or into a ion resin bed housing, all known to reduce or remove certain contaminate types or water hardness commonly associated with greywater. The influent transfer pump  30  produces enough pressure to push the influent  16  to and through the media  330 . 
         [0050]    The life span or loading of the media  330  is determined by the milligrams of contaminate contained within a liter, (mg/l). Once the greywater has passed through the pre-filter stage only microscopic contaminate such as; organics, chlorine, heavy metals, phosphorus, total coliforms remain. These types of contaminate are easily absorbed by the different individual types of media  330 . 
         [0051]    Since each of the different media types individually target certain types of contaminates, a suggested flow progression through the different housing system  550  should be practiced in order to reduce media loading and to preserve the media&#39;s longevity. As an example, detergents coming from the various greywater feed sources should be filtered out first to prevent media  330  surfactant loading and to improve the water&#39;s turbidity. 
         [0052]    During the flow progression the influent  16  should be first subjected to a starting media  76  in similar to cretaceous sandstone having a sieve size in the range of two hundred. As the influent  16  flows through the cretaceous sandstone and due to sieve size, detergent surfactants are adsorbed by sticking to individual sand gains thus removing them out of solution and helping to clarify the water. Further, any particulate solids which may have escaped the pre-filtration stage will be trapped by the sandstone preventing solids from transferring into the next media housing. 
         [0053]    The next media inline  74  should be in similar to manganese greensand having the same sieve size as the cretaceous sandstone. Manganese greensand is capable of reducing iron, manganese and hydrogen sulfide through oxidation and filtration and helps to reduce water odor perhaps from stagnate water stored within plumbing pipes or from a washing machine. Further like the cretaceous sandstone, the sieve size helps to improve turbidity by further trapping detergent surfactants and solids which may have escaped the cretaceous sandstone housing. 
         [0054]    The third inline media  72  should be in similar to activated carbon having a sieve size around ten. Activated carbon is commonly used in water treatment due to its ability to collect and confine certain types of contamination within its microscopic pores. Activated carbon is known to reduce or remove a wide range of environmental water contaminants including; non-biodegradable organic compounds (COD), absorbable organic halogens (AOX), toxicity, color compounds and dyestuffs, inhibitory compounds, aromatic compound including phenol and bis-phenol A (BPA), chlorinated and halogenated organic compounds and pesticides. 
         [0055]    A next inline media  70  should be in similar to kinetic degradation fluxion, (KDF). KDF is known to reduce or remove free chlorine, (up to ninety five percent) contained within the influent water. KDF media is composed of high-purity copper-zinc granules and when wetted performs a function of redox, (exchanging of electrons) to remove chlorine, hydrogen sulfide, water soluble heavy metals and microorganisms within the influent. 
         [0056]    According to EPA&#39;s water quality values, (EPA/625/R-04/108 a guideline for water reuse, the following list of contaminate and its acceptable levels for environmental release present the following filtration challenges to the greywater recycling system:

         [0057]    To one skilled in the art, any number of media housing or media types could be utilized during the filtration process to achieve a reduction or removal of EPA&#39;s listed contaminates or to achieve a desired degree of contaminate removal for environmental release and where flow progression, media types or the number of housing utilized during the treatment process should not be limited. 
         [0058]    In one embodiment, the present invention of the greywater recycling system  200  provides outlet options to works in conjunction with an ultra filtration system  450 . To meet the water quality standards as set forth by EPA for environmental release, the ultrafine filtration systems  450  contains the filters in the sub-micron range to produce a better quality of effluent coming out of the catch basin. 
         [0059]    Still in another embodiment, the ultra filtration system  450  contains the ultra micron filters  38  can be specified with special chemical coating known as being detrimental to bacteria and viruses. Water being very vulnerable allows housing of aquatic pathogens capable of causing disease and is easily adsorbed or leached through soils to contaminate groundwater aquafers or wells. 
         [0060]    Still in another embodiment, the ultra filtration system  450  contains a housing  40  which can be incorporated into the greywater recycling system  200 . The housing  40  contains ionic resin beads which are known to reduce or remove water hardness minerals or to treat certain types of aquatic pathogens within the influent stream. If the original tap water was delivered to the structure containing high levels of minerals then concurrently the waste greywater will be the same. 
         [0061]    Still in another embodiment of the current invention, the ultra filtration system  450  contains a reverse osmosis system, the (R/O) system  42 . The ultra micron filter  38  and the Housing  40  are often used to reduce or remove mineral content particularly prior to influent entry into the RIO system  42 . Such R/O system  42  is commonly used to produce potable water sometimes from a blackish or ocean water source or to provide a higher grade of water treatment. Prior for the influent to entering the RIO system  42 , the ultra micron filter  38  and the Housing  40  with resin beads are commonly used to help prevent filtration membrane loading due microscopic contaminate or high mineral content which traps within membrane pores causing them to plug or fowl creating a loss in efficiency. 
         [0062]    Still in another embodiment, the ultra filtration system  450  contains the capacitive deionization (CDI), the elector-dialysis (ED), or the distillation system which provide similar filtration functions as RIO system  42 . 
         [0063]    Still in another embodiment of the current invention, the ultra filtration system  450  contains a ultra-violet (UV) light system  44 . Once processing through the R/O membrane  42 , the influent is then subject to a UV system  44  which is known to be effective in disabling harmful viruses and preventing their reproduction. The UV is used in many applications including being used to disinfect both well and municipal water supplies. The UV system  44  is used as a second defense to insure micro-organisms are not introduced into the environment. 
         [0064]    Once traversing through UV system  44  the effluent is received by a check valve  46  which can be adjusted by the liquid pressure. The check valve  46  can be applied to control the effluent flow direction. In one embodiment to apply treated greywater for subsurface irrigation purposes, the effluent can be directed by the check valve  46  with the spring resistance to flow and exit directly to line  48  when there is no optional filtering devises such as the ultra micron filters  38 , the RIO system  42 , and the UV purification system  44  available. In another embodiment, when the above filtering devises are available (i.e., with the ultra micron filters  38 , the R/O system  42 , and the UV system  44 ), but due to a lack of spring resistance of the check valve  46 , the effluent flow is directed to the outlet line  50  which directs the flow to the optional ultra-filtration system  450 . 
         [0065]      FIG. 3  illustrates how the pre-filtration system  250  work in the greywater recycling and filtration. In  FIG. 3 , the pre-filtration system  250  receives influent flow through the manifold  54 . The manifold  54  mounts in an elevated position in relationship to the pre-filtration system  250  and mounts horizontally across the system housing  250 . The manifold  54  utilizes a series of rubber gaskets in which form a seal against the side wall of the ultra-filtration system  450  and prevents the influent leakage from the manifold  54 . 
         [0066]    As shown in  FIG. 5 , the manifold  54  comprises several portions. The incoming influent  16  flows into the first horizontal plane portal  32 . Next to the first horizontal plane portal  32  is a descending curvature  90  connected to the first horizontal plane portal  32  and is lowered in a relative height for allowing the influent to migrate under gravity. The descending curvature  90  is lowered comparing to the horizontal level of the first horizontal plane portal  32 . The lowered portion of the descending curvature  90  can allow the influent  16  to flow under gravity easily to the next portion of the manifold  54 . Next, the influent  16  flows into the second horizontal plane portal  92  connected to descending curvature  90 . The second horizontal plane portal  92  contains multiple descending exits  24  coupled with multiple micro-sized filters  26 . The exists  24  allow the influent to migrate downward through a series of micro-sized filters  26  and enter into the reservoir&#39;s storage system. 
         [0067]    The manifold  54  further contains an ascending curvature  94  connected to the second horizontal plane portal  92 . The ascending curvature is designed to be raised in a relative height comparing to the second horizontal plane portal  92 , for redirecting the overflowed influent back to the second horizontal plane  92 . In the case when the influent  16  flushes through the manifold  54  too fast to the third horizontal plane portal  96  and pass the exits  24  without going downward to the filters  26 , the overflowed influent  16  accumulating into the portion of the ascending curvature  94  can be redirected back into the lowered second horizontal plane portal  92  and then migrate into the filters  26 . The last portion of the manifold  54  contains a third horizontal plane portal  96  connected to the ascending curvature  94  for allowing the influent to exit, and a one-way backflow valve  48  attached to the third horizontal plane  96  for allowing the influent flow out to the sewer system in a one-way direction. The one-way flow valve  20  is connected to the sewer system. The one-way flow valve  20  is more commonly referred to as a “back flow preventer valve” which prevents sewage back up from entering into the catch basin system. In another embodiment, the one-way backflow valve  48  is pressure-operated to allow the influent coming from the manifold  54  to enter into the sewer line but not backflow into the manifold  54 . 
         [0068]    In another embodiment, there are multiple ascending curvatures  94  coupled with multiple corresponding third horizontal plane portals  94 . Still in another embodiment, there are multiple third horizontal plane portals in connection with multiple descending curvatures  90 . The design of multiple horizontal plane portals, together with multiple descending and ascending curvatures facilitate the influent  16  to be recycled and filtered in multiple stages with the micro-sized filters  24 , and to prevent overflowed influent  16  from directly flow through the sewer system. 
         [0069]      FIG. 3  illustrates the detailed structure and components of the pre-filtration system  250 . The pre-filters housing  26  of manifold&#39;s  54  features the micron rating that allow the influent  16  to migrate downwardly due to the pull of the gravity. The gravity migration of the influent  16  can work in a manner to withhold household solids such as hair, food particles or washing machine lint prior to the entry of the influent  16  into the catch basin&#39;s reservoir  22  ( FIG. 5 ). The pre-filters  26  are removable and further are reversely flushable, allowing the consumer to remove the pre-filters  26  periodically for inspection, cleaning or replacement. 
         [0070]      FIG. 4  illustrates the structure of the catch basin reservoir  22  enclosing the pre-filtration system  250 , and the attached tapered bay housing  55  for extra space storage. In reference to FIG.  4  a tapered bay housing  55  is used to house various electrical components of the greywater recycling system  200 . Both the housing  55  and the reservoir section  22  are accessed for internal maintenance by removing their enclosing lids  58  and  56 . The tapered bay section  55  is designated as the dry area of the system  200  and therefore is used to house electrical components such as an enclosed electrical box which distributes power to the UV system  350  and to the submergible the transfer pump  30  located inside the reservoir&#39;s storage system  350 . The tapered bay housing  55  also provides a housing area for the series of media filters  330  which require accessibility for maintenance. 
         [0071]    The tapered bay housing  55  is dedicated primarily to influent storage but also provides housing for the submergible transfer pump  30 , influent level sensor  15  and the receiving manifold  54 . 
         [0072]    The frontal  60  and the depth area of the tapered bay  55  and the reservoir taper  62 , is designed to tapper away from the structure allowing the system  200  of the current invention installation to be performed closer to a structure&#39;s foundation. 
         [0073]    In  FIG. 4 , the catch basin reservoir  22  allows the influent capacity expansion by receiving one or more additional reservoirs. Secondary reservoirs can be attached to the primary reservoir by using a plurality of tapering receiving slots  64  working in conjunction with corresponding plurality of tapering protruding blocks  65  and wherein, the first housing defines two or more protruding block  65  and thereon, the second housing defines two or more corresponding receiving slots  64  which allows mating migration and final attachment to occur between one or more secondary sections to a first section. 
         [0074]    The series of receiving slots  64  and corresponding protruding blocks are incorporated on each side wall of the reservoirs and therefore, the plurality of tapering receiving slots  64  are primarily located on the frontal side of the reservoir  22  correspond with a plurality of tapering protruding blocks  65  on the backside of the tapered bay section  55  allowing a slide together fit for attachment made between the two housings  64  and  65 . 
         [0075]      FIG. 5  illustrates a schematic view of how the components are installed inside the catch basin&#39;s reservoir  22  and inside the tapered bay section  55 . The reservoir section  22  provides housing for the open ended manifold  54  and for the series of pre-filters  26 . In  FIG. 2 , the influent flow  16  is received by the manifold  54  which directs the influent  16  towards the series of pre-filters  26 . Under gravity influence, the influent  16  traverses through the series of per-filters  26  and into the reservoir  22  where it&#39;s allowed accumulate. In cases where the manifold  54  may be overflowed with influent  16 , the opposite end of the manifold  54  is left open to provide entry into a one way back flow preventer valve  20  which connects directly to the sewer system  6  in  FIG. 2 . 
         [0076]    Within the reservoir  22 , a submergible pump  30  is housed which is electrically activated by the water level sensor  15  once the influent  16  accumulation level reaches a predetermine height. In  FIG. 5 , the submergible pump  30  and the water level sensor  15  are electrically wired together to a relay located inside the electrical box  80 . The relay is used to open or close an electrical circuit between the pump  30  and the water level sensor  15 . Once the influent  16  reaches a predetermined height, the electrical circuit closes via the relay and completes an electrical circuit between the sensor  15  and the pump  30 . Once the influent  16  inside the reservoir  22  has depleted, the sensor  15  then detects the low level water, and opens up the relay that breaks the electrical circuit can then cause the pump  30  to shut down. 
         [0077]    Once the pump  30  is activated, it pumps the influent  16  through the piping  68  which connects to media housing system  550  which contains cretaceous sandstone. The cretaceous sandstone  76  is used mainly to remove detergent surfactant and suspended solids which may have escaped the pre-filtration process. 
         [0078]    Once traversing through the cretaceous sandstone housing  76 , a pressure is created when the influent  16  under the pump  30  will be pushed into the media housing system  550  containing the manganese sandstone  74 . The manganese sandstone  74  is somewhat in redundant to the sandstone but does remove iron, hydrogen sulfide, reduces any stagnated water odor and helps to further improve the influent turbidity. 
         [0079]    In another embodiment, when traversing through the manganese sandstone housing  74 , the influent  16  is under the pump pressure that will be pushed into media housing system  550  which contains the activated carbon  72 . The activated carbon  72  is commonly used in the water treatment due to its ability to collect and confine certain types of contamination within its microscopic pores. The activated carbon  72  is applied to reduce or remove a wide range of the environmental water contaminants including; non-biodegradable organic compounds, absorbable organic halogens, toxicity, color compounds and dyestuffs, inhibitory compounds, aromatic compound, chlorinated and halogenated organic compounds and pesticides. 
         [0080]    Still in another embodiment, the influent traversing through the activated carbon housing  74  under the pump pressure will be pushed into the media housing system  550  which contains kinetic degradation fluxion, (KDF)  70 . KDF is known to reduce or remove free chlorine, (up to ninety five percent) contained within the influent water. KDF media is composed of high-purity copper-zinc granules and when wetted performs a redox function, (exchanging of electrons) to remove chlorine, hydrogen sulfide, water soluble heavy metals and to control microorganisms growth and accumulations such as; algae, bacteria and fungi. 
         [0081]    After traversing through media housing system  550  and before exiting the catch basin reservoir  22  through the piping exit  48 , the effluent  16  will undergo one final treatment process of the ultra-filtration system  450  where it&#39;s exposed to ultra-violet, (UV) light  44  to eliminate any bacteria or viruses which may have escaped the previous filtration processes. 
         [0082]    In understanding that the catch basin reservoir  22  was designed to operate as a standalone system it can also be equipped to operate downstream of other optional equipment such as an ultra or reverse osmosis systems or a combination of both as described above in  FIG. 2 .
