Waste water drainage and recovery system

DETAILED DESCRIPTION By the system of the present invention, the need is eliminated for a central gravity sewer or forced sewer collection system.
Further, the system greatly reduces the size and need for both water and sewer treatment facilities.
The system also eliminates the need for the installation of a reuse water conveyance system from a treatment facility for treated waste water back to sprinkler systems or irrigation systems of the end user.
By the present invention, potable water is delivered to a household.
This water is used, flowing by gravity, to an on-site treatment facility such as a septic tank.
The solids are collected at one end of the septic tank and when the liquids build up to a sufficient height, they run over a weir into the other end of the septic tank.
From there, the liquids flow out through an opening to a chlorine-contact chamber that ensures killing of any bacteria present in the leachate from the septic tank.
This treated water flows from the chlorine-contact chamber by gravity into a drain field, down through percolating sand and into natural filter media which is the earth.
The water then flows downward and into the existing water table.
The recovery system of the present invention is installed adjacent to the septic tank and drain field at a distance of some 14 to 20 feet below the drain field.
The treated water percolating down through the natural filter media (earth) flows into the pre-existing water table and then into a recovery pipe and is brought back to the surface by a pump.
The treated water is passed through a mineral remover or any additional device which is necessary to bring the water to an acceptable state for irrigation purposes.
The recovered water is used through a sprinkler system for irrigation purposes.
As an example, 50% of the water used in the State of Florida is used for domestic or commercial irrigation and in most cases, this water is potable water which has been through an extensive and expensive treatment facility.
The extensive treatment of water suitable for irrigation is not necessary when using the present invention
