GRAY WATER 

Applications/Use  - 

Residential   -- Gray water recovery for toilet flushing and subsoil irrigation

Commercial – Hotels/Motels, University Dorms, Schools, Cafeterias, Homeless Shelters, Laundromats, laundry plants, food processing, fitness centers/gyms, restaurants, catering, correctionfacilities, military barracks

Engineering

Residential  -  Unless the installation is very unique no engineering is required

Commercial – Solutions are modeled based on specifics gathered about the building/application taking into account multiple factors –

Gallons of gray water generated, types of fixtures ( water use gallons per minute or flush) – faucets, showerheads, toilets, urinals - # of floors in the building, pipe distances etc to arrive at a design which meets the facilities needs.

Beyond the prelim design, engineering/startup services are available on an approved project basis

How It Works

Residential - The system in one compact unit collects the gray water from the showers/baths, bathroom sinks and washing machines through a pre-filter installed in a 3" pipe going into the BRAC system. This pre-filter is primarily used for removing the lint produced by the washing machine but also hair from other sources - it's use reduces the number of times you will need to clean the internal filter. The water is filtered to a 100 Micron level, treated with a minimal amount of chlorine ( .5 to 1 PPM, less than 1/3^rd of the levels found in the municipal water supply) and stored in the BRAC tank.

The automated water monitor in the system treats the water in the tank with chlorine to keep it safe and disinfected. If you are away from the home for more than 12 hours or on vacation it will treat the gray water to keep it disinfected ( check chlorine levels before leaving on vacation). If all the gray water is used up in meeting the homes needs the unit's water is kept at a safe level by providing a water makeup from either the fresh water supply for the home or in many cases rainwater storage. The BRAC system can be used to flush toilets or be used for irrigation  -  this varies by location and should be confirmed with your local building inspector. With it's electronic pump the system will provide water at pressures of from 30- 50 PSI and can deliver up to 18 gallons per minute.

Commercial - Functionally the commercial systems work the same as the residential units but with many more subsystems capable of meeting the scope of a commercial job. The water is collected the same way from showers, baths, laundry etc and delivered to a lift station, the water is then processed through a dual filter station before being delivered to one or more 1700+ gallons storage tanks. The water is processed as needed with chlorine, treated with blue dye and delivered to flush toilets or subsoil irrigation. Water delivered into a multistory building will have additional pumps and pressure tanks to meet the required pressure and water flow to deliver water to tank type and flush valve toilets. See the Commercial manual in the down load section for greater detail. 

How Much Water Will It Save

Residential -  Systems can save from 30 – 45% of the gray water generated 

Commercial – Systems can save 35 – 60% of the water generated depending on the facility and water fixtures

Incentives

None generally available but some are being discussed in some communities.

LEED Points

Modeling

Net Zero (Approaching)

When combined with a rainwater harvesting system ( sized to the climate/rainfall) it is more than possible to arrive at a Net Zero water home or facility through installation of water conserving fixtures, faucets, shower heads, toilets etc) and appliances ( washers and dishwashers)
