Greywater Systems
Greywater Systems Designed for Efficient Water Reuse
An average home can produce more than 30,000 gallons of greywater each year from sources like showers, laundry, bathroom sinks, and bathtubs. Instead of sending that relatively clean water back to the sewer, a properly designed greywater system can safely re-use it for outdoor irrigation and select indoor applications.
Dig Cooperative provides custom greywater system service throughout the Bay Area, helping homeowners reduce water use, support healthier landscapes, and rely less on potable water. From simple gravity-fed systems to advanced filtration systems, we design and install greywater systems Bay Area homeowners can use to irrigate trees, shrubs, vines, and other drought-tolerant plants while supporting long-term water conservation goals.
Popular Greywater Systems for Homes & Landscapes
We provide a range of greywater system options designed for different properties, landscape needs, and water reuse goals, including:
- Laundry-to-Landscape Systems — These laundry-to-landscape systems redirect wash water from clothes washers to outdoor irrigation. Most single-family systems do not require permits and offer an affordable way to conserve water.
- Gravity-Fed Mulch Basin Systems — Gravity systems send greywater into mulch basins that naturally filter and distribute water around trees, shrubs, and landscape areas while helping reduce overall water use.
- Pumped Drip Irrigation Systems — These pumped graywater irrigation systems move water through subsurface drip tubing for more controlled irrigation on larger landscapes or sites where gravity flow is not practical.
- Indoor Greywater Reuse Systems — Advanced water treatment and filtration systems, including the NSF 350 Certified AQUALOOP System, can treat shower water and sink water for approved indoor reuse applications like flushing toilets and washing laundry.
- Constructed Wetlands & Sensitive Site Systems — We design advanced wastewater treatment systems, including constructed wetlands, for properties near protected waterways or environmentally sensitive landscape areas.
