     FIELD OF THE INVENTION 
     The present invention relates to drainage for land areas. More particularly, the present invention relates to a system for draining land areas, such as golf courses, farms and homes, through the collection of water into a principal catch basin, and pumping the drainage water out using the energy of a nearby water line to drive a venturi. The venturi will be controlled with the operation of a float and a hydraulic valve so that there will not be any need for any electrical source to drive the pump or operate the controls. 
     BACKGROUND OF THE INVENTION 
     The present invention is in the technical field of drainage. More particularly, the present invention is in the particular area of seepage drainage and the removal of water by pumping, or a means other than gravitational drainage flow. The most common method to drain water that has been collected from seepage or surface flow is to grade pipe to a lower point. However, in many cases, particularly lands that are near sea level or very flat property, there is no open airspace (for the water to flow) that is lower than the water being collected, or if there is, it is such a long distance away that the installation of the drainage becomes impractical. The alternatives to gravitational drainage currently consist of either siphoning the water to the nearest relief point Hurley U.S. Pat. No. 4,919,568, or pumping the water to the nearest relief point. A siphon is typically used when there is a lower airspace available, but it is a long distance away. It can be less expensive to siphon the water to the relief point than to take the water there by running pipe on grade. If there is no lower airspace, the only option is to pump the water out of the area. The installation of the pump requires electricity in some form to run the pump. The cost of running this electricity or setting up a solar charged battery bank can be prohibitively expensive for a small area. 
     SUMMARY OF THE INVENTION 
     The present invention uses the energy of a nearby water system to drive a pump to collect seepage water from a permeable basin, Hurley U.S. Pat. No. 4,988,235, using the energy of a nearby water line or pressurized irrigation system. The energy of the water system would suck drainage water through a venturi and be operated with a float and hydraulic valve, thus, allowing one to pump water from a basin without the need of electricity.

     DETAILED DESCRIPTION OF THE INVENTION 
     
       FIG. 1 
     
     Referring now to the invention in more detail, in  FIG. 1 , water comes from a water source through a pipe  14  to a gate valve  1 . This is connected to the rest of the system by a union  2 . The water flows through a normally closed hydraulic valve  3 . This valve can be taken out by removing the union  4  and  2 . The water next flows through a venturi  5 . Drainage water enters the venturi  5  through the uptake pipe  6 . A check valve  7  keeps water from flowing back into the basin when the pump is off. The uptake pipe is connected to the venturi  5  by a union  8  for easy servicing. An adapter  9  connects the discharge line. A rigid pipe  12  is affixed to the sidewall and connects the hydraulic tubing from the valve  3  to the float  11 . The float opens and closes a bleed-off valve  10 . Both the source water from  14  and the drainage water entering through the uptake pipe  6  combine and go out through the discharge pipe  15 . 
     
       FIG. 2 
     
     Referring to the invention in more detail,  FIG. 2  represents the apparatus described in  FIG. 1  placed in a permeable basin  16  that collects ground water  20  through the sidewalls of the basin and seepage line  18 . It also collects surface water through solid line  19 . 
     
       FIG. 3 
     
     This represents the invention in the ground. The apparatus in  FIG. 1  is placed in the basin  16  in  FIG. 2 . The basin  16  is placed in the ground  21 , and collects ground water  20 . The apparatus in  FIG. 1  pumps the ground water  20  out to pipe  22  at a higher elevation than what it was collected. 
     In further detail, still referring to the invention of  FIG. 1 , water from any source with pressure, even city water pressure, is enough to operate the venturi. Water flows through a pipe  14  of any size. Gate valve  1  is placed outside of the main structure, so that if the main parts of the apparatus placed inside the basin must be serviced or replaced, the water can be off while the service work takes place. For smaller units, all piping and valves are smaller. For larger units that have the potential of a higher flow rate, larger pipes and valves can be used. Unions  2 ,  4 , and  8  are all placed in the system to aid in the servicing of the unit from the surface. The water enters hydraulic valve  3 . This hydraulic valve  3  is normally closed. It is held closed by the buildup of water from a diaphragm in valve  3  to valve  10 , by way of a hydraulic tube  13 . When water rises in the basin, and the float  11  raises, it opens valve  10 , and the pressure bleeds off of valve  3 , allowing it to open up and flow water through the venturi  5 . As the source water flows through venturi  5 , it creates a vacuum that sucks the water from the bottom of the basin. When all of the water has been removed, the float  11  returns to the down position, which closes valve  10 . Once valve  10  is closed, the water that bleeds from valve  3  builds up pressure and closes the diaphragm causing the water flow to stop. 
     In further detail on  FIG. 2 , the apparatus in  FIG. 1  is shown placed in a permeable basin  16 . This permeable basin  16  collects seepage water and surface water. The seepage water enters through the geotextile bag  17 , and the seepage drainage  18 . The surface water enters through the grate on basin  16  and through the solid pipe  19 , that may be connected to other drainage inlets. 
     In further detail on  FIG. 3 , it shows that the ground water  20  in the profile  21  is lowered by the process of the apparatus in the permeable basin  16  collecting water. This can be applied to water that is on flat properties, as the result of its closeness to a lake or an ocean, or it can be ground water that is moving through a profile from entering on the surface at a previous point. This would apply to areas such as hillside springs or saturated upper profiles, such as turf areas on golf courses and lawns. 
     In further detail on  FIG. 1 , the apparatus could be made of piping of any size. The limits on the pipe size would only be limited by the pressure of the source water. The lift that could be created would determine the maximum size of the basin. In situations where there was high pressure source water available, basins of depths of 30 feet could easily be built. 
     The apparatus could be made of any material, plastic or metal pipe. 
     The apparatus in  FIG. 2  could be either permeable, or a solid walled basin, if the only objective was to collect surface water. 
     The advantages of the present invention includes the ability to pump water to a higher elevation without the need for electricity. Using the energy of nearby water systems, either city water or pressurized irrigation water, as is found on golf courses, one can pump drainage water without the need to run electrical service to the site or to run a battery bank. Using this, in combination with a permeable basin, allows one to collect deep seepage water inexpensively. It can be used on flat coastal properties or to collect water from deep hillside springs. Since the entire apparatus is serviceable from the surface with the removable unions, the parts can be installed, serviced, and replaced without getting down in the hole. This gives one the opportunity to build these units to great depths, such as 20 feet deep into the ground, to remove the moving ground water and stabilize hillsides without having to dig a gravity pipe for relief on the water that is collected at these depths. In comparison to a siphon, it has many advantages. A siphon is limited on coastal properties to only being able to drain to sea level. On these types of properties, multiple siphons are usually used to move water to one central pump site. Without the central pump site to create an airspace below sea level, the siphons are of limited use. In addition, each siphon site needs a new pipe that is airtight to connect the siphon basin to the relief. With this invention, the water can often be pumped to an existing pipe that was already in the ground. Even though that pipe may be above the elevation of the level at which it is now desired to collect the water, the old shallower pipe can be used because we are lifting the water with the apparatus. 
     In broad embodiment, the present invention uses the energy from a nearby water source to suck drainage water in ground applications without the need to use electrically operated components of any kind. There is no need for any electrical controllers or valves to turn the system on or off, or for any electrical pumps. 
     While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
