## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The instant invention relates generally to monitoring systems, and more particularly to a device and system to monitor the level of a sludge in septic tank to alert an individual when the system should be pumped.
2. Description of the Related Art
Septic tanks are used as an alternative to sewer systems in locations where those systems are not available. A septic tank generally consists of a tank connected to an inlet wastewater pipe at one end and a septic drain field at the other end. Waste water enters the tank through the inlet and solids to settle to the bottom of the tank while scum floats and is allowed to exit to the septic drain field.
Septic tanks despite being a good alternative to a sewer system do come with certain limitations. If the liquid in a septic tank fills to a level at or above the incoming sewer drain line, the sewer drain line may back up and cause potentially harmful sewage to flood a house or building. A sewage flood can be hazardous to the health of people and animals, and can also cause extensive property damage. Furthermore, the solid levels in the tank can rise to the level of the outlet pipe thus depositing solid waste into the drain field. The presence of suspended solids in the drain field will, over time, result in the field becoming clogged by the solids to such an extent that it can no longer absorb and disperse the polluted water. This failure will typically be evidenced by pollution of ground and surface water. This can be an expensive problem to fix. In order to prevent these issues often requires the septic tank to be pumped before eat reaches a level resulting in failure of the system.
The most common method for determining the levels of the septic tank is a visual inspection of the tank. This requires the septic tank cover to be removed which can be an exhaustive process that yields an inaccurate reading. Another common method is to remove the access cover to the septic tank and to measure the depth of each of the three layers by pushing a “flapper stick” into the tank. The flapper stick is configured so that it can be used to gauge the bottom of the tank. Direct observation of the stick after removal indicates the depth of the bottom sediment. The process of removing the septic tank cover and removing reading the stick can be a very unpleasant task as it exposes the operator to the open septic system. An additional limitation of these testing procedures is tester, typically the owner of the property, must be present to test the levels of the tank. Septic tanks are common in many vacation homes as they are often in more remote locations requiring the use of a septic system. As a result the owner will often not be at the property to test the system.

The monitoring device 1 further comprises a probe arm 4, wherein the probe arm 4 extends downwardly from a lower end 23 of the base unit 2. In the embodiment shown in FIG. 1A, the base unit 2 is in a perpendicular orientation with respect to the probe arm 4, thereby enabling the monitoring device 1 to be mounted on a vertical pipe in the septic tank (i.e. wherein the pipe is oriented parallel to the probe arm 4 of the monitoring device 1). In one embodiment, the probe arm 4 further comprises a light emitting diode (“LED”) arm 12 and a dark sensor photocell arm 14, wherein the LED arm 12 and the photocell arm 14 are contained within the probe arm 4. Preferably, the LED probe arm 12 and the dark sensor photocell arm 14 are oriented parallel to one another and extend vertically downward. The LED probe arm 12 further comprises a plurality of LED probes 16; the dark sensor photocell arm 14 further comprises a plurality of dark sensor photocells 18 wherein each dark sensor photocell 18 is paired with a corresponding LED probe 16. In one embodiment, each corresponding LED probe 16 and the dark sensor photocell 18 are equidistantly disposed along the LED probe arm 12 and the dark sensor photocell arm 14 so that each are positioned at the same distance from the bottom of the septic tank. In a preferred embodiment the LED probe 16 and the corresponding dark sensor photocell 18 are positioned within the septic tank at a level that is equivalent to the septic tank being one third full of sludge or any other similar debris. Additionally, in one embodiment, the LED probe arm 12 and the dark sensor photocell arm 14 each contain further comprises a plurality of circuit wires 20, 22 respectively to transmit a signal and/or alarm remotely to an individual operator. In the embodiment shown in FIG. 1B, the base unit 2 is in a parallel orientation with respect to the probe arm 4, thereby enabling the monitoring device 1 to be mounted on a horizontal pipe in the septic tank (i.e. wherein the pipe is oriented perpendicular to the probe arm 4 of the monitoring device 1).
FIGS. 2A-2B illustrates side views of one embodiment of the monitoring device 1, wherein the base unit 2 further comprises an inner radius 24 and a cavity 26. Preferably, the inner radius 24 of the base unit 2 possesses a radius substantially equal to the radius of the corresponding inflow or outflow pipe to which the monitoring device 1 will be affixed in order to create a snap fit between the pipe and the monitoring device 1; creating a snap fit simplifies the installation process of the monitoring device 1. In one embodiment, the cavity 26 located within the base unit 2 allows for the snap fit to be achieved by reducing the rigidity of the cavity of the base unit 2 thereby allowing for a slight tolerance of the inner radius 24 so that the monitoring device 2 accepts the pipe to which the monitoring device 1 is affixed. In the embodiment shown in FIG. 2B, the base unit 2 is in a perpendicular orientation with respect to the probe arm 4, thereby enabling the monitoring device 1 to be mounted on the top of a pipe in the septic tank. Preferably, the base unit 2 snaps onto a corresponding pipe via an overcam (over-center) hanger opening, wherein the radius of the base unit 2 matches the radius of the attached corresponding pipe. Additionally, the opening of the base unit 2 is narrower than the pipe to provide the mechanical force as the base unit 2 is forced open when the base unit 2 is being pushed onto the pipe unit it pops over the pipe and subsequently snaps onto the pipe. In yet another embodiment, a joint 29 is present at the lower end 23 of the base unit 2, where the base unit 2 meets the probe arm 4 to enable various attachment orientation designs.

The preferred embodiment utilizes one monitoring device 1 affixed to an inflow pipe and one monitoring device 1 affixed to an outflow pipe. Each monitoring device 1 may be fixed to either the vertical or horizontal portions of the inflow or outflow pipes utilizing the base unit 2. Furthermore, the probe arm 4 extends downwardly from the base unit 2 in a direction perpendicular with respect to the bottom of the tank.
FIG. 8 illustrates an alternate embodiment of the monitoring device 1. In this embodiment the monitoring device 1 comprises a sensor arm 50 that extends downwardly into the septic tank in a direction perpendicular with respect to the bottom of the septic tank. The sensor arm 50 comprises a plurality of sensor housings 51 wherein each sensor housing 51 further comprises one LED sensor 52 and one photocell sensor 54. The sensor housings 51 are spaced vertically along the length of the sensor arm 50. The vertical positioning of the sensor housings 51 is selected by the user in order to achieve the proper readings desired. The sensor arm 50 further comprises a wire 56 at the top end of the sensor arm 50. The wire 56 comprises a wire outer casing, a plurality of signal wires, and a plurality of power wires. The wire outer casing shields the plurality of signal wires and plurality of power wires from damage.
FIG. 9 illustrates an alternate embodiment of the monitoring device 1 further comprising a mounting device 57. The device 57 further comprises a pipe clamp 58 and a holding arm clamp 59; the pipe clamp 58 and the holding arm clamp 59 are integrally coupled and oriented so that the sensor arm 50 is oriented vertically and pointing downward. In this embodiment, a hinged joint 61 is present between the pipe clamp 58 and the arm clamp 59 to allow for the monitoring device 1 to be utilized on both vertical and horizontal pipes.
FIG. 10 illustrates an alternate embodiment of the monitoring device 1 further comprising an above ground solar array 60, wherein the solar array 60 further comprises an indicator light 62. In this embodiment, the solar array 60 provides power to the monitoring device 1 through a connecting wire 56. The indicator light 62 provides status indicators to the user. In one embodiment a non-illuminated indicator light 62 indicates a properly functioning system. In one embodiment the indicator light 62 will illuminate red to tell the user to pump the septic tank and will indicate orange to tell the user the septic tank will need to be pumped soon.
FIGS. 11-13 illustrate one embodiment of the sludge level monitoring system 1 wherein the sensor housing 51 comprises a LED sensor 52 and the photocell sensor 54. In this embodiment, the LED sensor 52 is affixed to the left side of the sensor housing 51 and the photocell sensor 54 is affixed to the right side of the sensor housing 51. The alignment of the LED sensor 52 and the photocell sensor 54 inside the sensor housing 51 creates a gap between the LED sensor 52 and the photocell sensor 54 in which liquid and debris pass for detection. The LED sensor 52 and photocell sensor 54 are preferably round in shape so that falling debris falls around the sensor housings 51 but does not accumulate resulting in inaccurate readings.
FIG. 14 illustrates use of an alternate embodiment of the monitoring device 1 in use during operation. In this embodiment, the single sensor arm 50 extends downward into the different levels of the septic tank. Preferably, locations of the LED sensor housing 51 are selected to optimize readings; the readings are transferred to the solar array 60 which contains the indicator light 62.
In operation, the instant invention relates to a device and system for monitoring the level of sludge in a septic tank, wherein at least one monitoring device 1 may be located within a corresponding septic tank. In one embodiment, upon installation of the instant invention is powered on and synced with a modem. The home or business owner must access a web page and enter the unique product code to register the system. Subsequent, the operator of the system is then guided through an account set-up and provided with the account information. At this point the system may be programmed via a calendar or placed in auto-mode. Preferably, the monitoring system will have a minimal default setting to ensure a base level of measurement; the user may change any calendar and other settings via the smart phone app or webpage. The system is preferably always in a low-power “sleep” mode until a timer wakes each monitoring device 1 to perform a test. One such test involves the LED flashing on and the photocell on the probe arm 4 reading the level of light emitted. If the photocell reads a given level of light above a pre-determined number, then the system determines that the liquid in the tank is clear, and the monitoring device 1 sends a “green/OK” signal to all interfaces registered to receive data, including an interface that may also be located inside the operator's home or business. As time progresses, and with each subsequent test the system will indicate the reducing light levels and send appropriate updated message as the septic tank water becomes more saturated with falling debris, such as “amber/warning/pump soon” to all interfaces. In a “pump soon” scenario the system will enter an auto-tracking mode and test via a predetermined program, over-riding the operator's schedule to ensure a much closer monitoring as the need to empty the septic tank draws closer. In a scenario when the system arms, the LED illuminates, and the photocell receives little or no light then the device will send a “red/danger/pump now message to all interfaces.
FIGS. 15A-15B illustrate yet another embodiment of a device and system for monitoring the level of sludge in a septic tank, wherein a monitoring device 100 comprises a base unit 102 for preferably securing the monitoring device 100 to an outflow or inflow pipe (see FIG. 7) within a septic tank (see FIG. 7). The monitoring device 100 further comprises a probe arm 104, wherein the probe arm 104 extends downwardly from a lower end 123 of the base unit 102.

FIG. 20 illustrates a block diagram for installation of the instant invention within a septic tank and each respective monitoring device 1. Initially, at step 100, the operator of the system pumps the septic tank where the monitoring device will be installed for use. Once the tank is pumped, at step 102 the operator determines the volume of the septic tank, and then further determines the one-third full level of the septic tank at step 104. Subsequently, at step 106, the operator presses the “ON” button 30 on the monitoring device 1 thereby arming the system. At step 108, the installer holds down the “ON” button 30 until the “ON” button 30 flashes; when the “ON” button 30 flashes the operator continues with the installation of the system. However, when the “ON” button 30 does not flash the system returns to step 108, wherein the operator will again hold down the “ON” button 30 until there is flashing. Once the “ON” button is flashing, the operator of the system identifies a corresponding input signal at step 110 relative to the septic tank size where the monitoring device 1 is being installed and which was measured in step 102. Once the input signal is determined, then at step 112, the operator presses the “ON” button 30 the number of times that correspond to the input signal identified at step 110. When the input signal entered is correct, then at step 114, the “ON” button stops flashing and the operator continues with the installation. Alternatively, when the “ON” button 30 is still flashing the input has not been correctly entered and the system returns to step 108 to hold down the “ON” button to re-start the process of entering the correct septic tank size calibration. Following a correct input signal, at step 116, the system enters a setup sync mode after a successful input. At step 118, the septic tank sludge level monitoring system sends a broadcast to a receiver module 150 (see FIG. 22); at step 120, the operator adds a battery to the receiver module. At step 122, the operator presses the screen on the receiver module causing the module and the “ON” button 30 to flash in unison. Then at step 124, the operator preferably connects the receiver module to a Wi-Fi network. At step 126, operator of the system may visit a website provided by the monitoring device 1 on any internet compatible device. At step 128, the operator enters an accompanying serial number from the manufacturer specifications according to the website instructions. At step 130, the operator may enter preferences on the website according to the instructions, and then at step 132, the operator completes the account setup. Finally, at step 134, the website sends a signal to the receiver module, and at step 136, the monitoring device 1 begins monitoring after receipt of the signal sent in step 134.
FIG. 21 illustrates a block diagram for one embodiment for monitoring the sludge levels inside a septic tank utilizing the system described above and at least one monitoring device 1. Initially, at step 150 the monitoring device 1 wakes itself from a lower power state. The intervals at which the system performs the operations at step 150 are predetermined by the operator. At step 152, the monitoring device 1 performs a self-check for failures. When a failure is detected the system proceeds to step 154, wherein the monitoring device 1 transmits a failure message to the receiving module and subsequent at step 156, the receiving module sends the failure message to the website. Next at step 158, the website sends an alert to the registered user device of the operator regarding the failure; conversely, when no failure is detected the system continues the monitoring process. At step 160, the LED sensor 16 illuminates on the sensor arm 12 and is read by the dark photocell sensor 18 on the dark photocell sensor arm 14. At step 162, corresponding signals gathered in step 160 are sent to the receiver module and then at step 164, the receiver module receives the signals sent from the monitoring device 1. At step 166, the receiver module transmits the signals to the website and then at step 168, the website transmits signals to the registered operator device. Finally, at step 170 the receiver module displays a color indicator, wherein a green color indicator indicates a safe state of the septic system, an orange color indicator indicates the system will need to be pumped soon, and a red color indicator indicates the system needs to be pumped immediately.
FIG. 22 illustrates a block system diagram of one embodiment of a computing environment in which the monitoring device 1 preferably operates. In this system, the monitoring device 1 is located a septic tank (not shown) and is in data communication with the receiver module 150 preferably via a wireless-free (“Wi-Fi”) connection to transmit readings relating to the depth of sludge and other materials being monitored in the septic tank. Ideally, the receiver module 150 would be located in a corresponding residential home or business that is situated near where the monitoring device 1 and the septic tank is being monitored. The receiver module 150 receives signals from the sensor arms 112, 114. The receiver module 150 is in electronic communication with a computing network 160. In the preferred embodiment the computing network 160 is a website for the septic tank sludge level monitoring system 1. The computer network 160 is additionally in electronic communication with the 170 user device. The receiver module 150 therefore transmits signals to the user device 170 via electronic communication with the computing network 160. Furthermore, the receiver module 150 preferably is in data communication with a computing network 160 that provide a user's account with a status update on the monitoring of the septic tank. Finally, the computing network 160 transmits a message via data communication to a user's assigned mobile device 170 to provide status updates to the user on whether or not the septic tank has reached capacity or is still operating a reasonably safe level.
In conclusion, herein is presented a septic tank sludge level monitoring system. The invention is illustrated by example in the drawing figures, and throughout the written description. It should be understood that numerous variations are possible, while adhering to the inventive concept. Such variations are contemplated as being a part of the present invention.
