Abstract

This invention relates to a water reclamation system for reclaiming grey water and ground water from sources associated with a domestic dwelling and subsequently utilizing such water in conjunction with a landscape irrigation system. The system generally comprises a storage reservoir which is fluidly connected to a main irrigation line comprising the landscape irrigation system. The reservoir includes a number of inlet conduits connected thereto which are in fluid communication with grey water sources from within the dwelling and with yard drains which receive ground water. The reservoir also includes an overflow line interfaced thereto which is adapted to drain excess water from within the reservoir to a main sewage line. The water provided to the irrigation system via the storage reservoir is supplied only as an alternative to water which may be supplied thereto via a main water line.

Claims

1. A water reclamation system for use with a landscape irrigation system, comprising:

a storage reservoir located adjacent a domestic dwelling;

a first reservoir inlet conduit for inputing gray water from sources within said dwelling into said reservoir;

a second reservoir inlet conduit for inputing gray water from sources outside of said dwelling into said reservoir;

at least one drain disposed within a lawn of said dwelling and connected to said second inlet conduit for inputing ground water into said reservoir;

a first reservoir outlet conduit for placing said reservoir in fluid communication with said landscape irrigation system;

a second reservoir outlet conduit for providing an overflow drain line from said reservoir to a sewage line;

a pump positioned within said first outlet conduit for pumping water from within said reservoir into said irrigation system; and

a filter positioned within said first outlet conduit for filtering water pumped from said reservoir before the water is inputed into said irrigation system.

2. The system of claim 1 further comprising a main irrigation line for placing said irrigation system in fluid communication with a water main, said first outlet conduit connecting said reservoir to said irrigation line.

3. The system of claim 2 further comprising a check valve positioned in said first outlet conduit between said filter and said irrigation line for preventing the flow of water from said water main into said reservoir.

4. The system of claim 3 further comprising a gate valve positioned within said irrigation line between said water main and said first outlet conduit for selectively placing said irrigation line in fluid communication with said water main.

5. The system of claim 4 further comprising a water meter positioned within said irrigation line between said gate valve and said first outlet conduit.

6. The system of claim 5 further comprising a first back-flow preventer positioned within said irrigation line between said water meter and said first outlet conduit for preventing the back-flow of grey water from said reservoir into said water main.

7. The system of claim 1 further comprising a second back-flow preventer positioned within said second outlet conduit for preventing back-flow from said sewage line into said reservoir via said second outlet conduit.
