Grey water processing and distribution system

Abstract

The Grey Water Processing and Distribution System is a self-contained fully functional grey water collection, processing and dispersing system that runs on grey water collected from internal grey water sources and supplies filtered water to the house's landscaping irrigation system as well as filtered and sanitized flush water to the house's toilets and washing machine for usage and requires standard local power. It incorporates a unique self-cleaning fine screen filter system. The central digital control unit monitors and runs the various system components and manages the house's landscaping irrigation system. The digital control unit also makes sure that the toilets are never without flush water and protects the irrigation system against under and over watering. The internal and external plumbing also allows for the system to be completely bypassed in the event of power failure or the introduction of undesirable contaminants into the grey water source stream.

Description

FIELD OF THE INVENTION[0001]The present invention provides a system and method which collects grey water and processes it to supply water of sufficient quality for specific reuse purposes. In particular, the system and method comprising a grey water and rainwater source collection sub-system, a digital control unit having input sensors to detect water levels, water flow, water pressure and having control outputs to control integrated pumps and valves, an automatically controlled multi-port valve, an irrigation sub-system and a toilet flush water sub-system.BACKGROUND OF THE INVENTION[0002]Grey water is a part of the residential buildings waste water without black water. Black water is part of the household waste water and is the drain from toilets therefore containing urine and / or feces. It is the grey water that drains from bath tubs and shower trays, washbasins and washing machines and may also contain high-strength kitchen waste waters that are significant within this application...

AI Technical Summary

Benefits of technology

"The Grey Water Processing and Distribution System has several technical effects. Firstly, it reduces the strain on the environment by reducing the amount of reusable water put into sewage treatment facilities. Secondly, it provides a source of filtered water for irrigation and sanitization purposes. Thirdly, it can be easily incorporated into a single family dwelling. Fourthly, it helps to maintain the fertility of soil by reclaiming nutrients. Fifthly, it reduces the amount of chemicals used in sewage treatment. Lastly, it helps to create a manageable size that can be easily installed."

Problems solved by technology

It is not wise to irrigate landscape with great quantities of drinking water when plants thrive on used water containing small bits of compost.

Although this patent describes an apparatus for utilizing gray water for flushing a toilet it does not have the involved computer controlled system nor does it offer the capability of passing the water through a unique self-cleaning fine screen filter system supplying irrigation water or through a filter and sanitizing means prior to pumping the water through a fine filter before being made available to the toilet and washing machine usage or returning back through the system.

This patent describes a grey water recovery system that comprises a filter tank having a filter medium therein but does not incorporate the unique self-cleaning fine screen filter system and does not incorporate the filters and sanitizing means before making use of the water.

This system does not deal with the use of the water directed to the toilet and does not incorporate the extensive computer controlled filtering processes.

None of these previous efforts, however, provides the benefits attendant with the Grey Water Processing and Distribution System.
