Smart Greywater System FAQ

The Smart Greywater System is a completely automated system delivering filtered greywater to landscape drip irrigation, with automatic city (or well) water backup. The system is compatible with all brands of irrigation controllers, operates the same as a traditional irrigation system, and is ideal for renovation or new home projects. The Smart system also includes monitoring equipment that allows you to view information about tank levels and water usage remotely via an internet-enabled dashboard.

Maybe. Every home’s plumbing system is unique and will need to be evaluated by a professional plumber to assess the feasibility of installing the Smart Greywater System. The greywater system can be easily integrated into new homes or renovations where the bathrooms (and plumbing) are being changed.

Greywater from the laundry, showers and bathroom sinks drains to a below or above ground tank (250-300 gallons). When the irrigation controller starts watering, a submersible pump in the tank pumps the greywater through a filtration system before being dispersed into the landscape through drip irrigation tubing. If no greywater is available in the tank, the system automatically supplies city water to the drip tubing. The filtration system is automatically cleaned, so maintenance is required only once per year.

There is no limit to how many plants can be watered. However greywater cannot be used with spray irrigation and must be applied through sub-surface drip tubing. Please see our General Greywater FAQ for more information on types of plants.

The average person produces 31 gallons per day from high efficiency showers, sinks and laundry. A typical family of 4 will produce 45,000 gallons of laundry water per year that can be used to water plants.

Yes, in most cases. Some states (California) require that the drip tubing be buried 2” under soil or mulch so some additional work on the irrigation system may be required. Please refer to the Smart Greywater System Manual for more information on interfacing with existing irrigation systems.

Maybe, with some additional work. Greywater cannot be sprayed through the air, so the lawn spray valves will need to be separated from the drip valves, and a new city water-only supply pipe installed to the spray valves. A new irrigation controller may also be needed. The Smart Greywater System allows up to (4) city water-only spray valves without re-plumbing the irrigation system piping.

Very little! We recommend a general systems check once per year, the greywater tank bag filter be replaced once every 2 years, and the greywater tank sediment removed once every 3 years. WaterSprout offers annual maintenance contracts to ensure system upkeep.

Although some states allow “simple” systems to be installed without a permit (our Simple Greywater System, for example), you will most likely need a permit to install the Smart Greywater System.
