IrriGRAY helps California homeowners design beautiful lawns, gardens, and outdoor living spaces around the water their home already creates — ideal for new homes, major remodels, and full landscape projects.
An intelligently designed graywater irrigation system by WaterReNu — planned into new construction, major remodels, and full landscape projects rather than retrofitted onto an existing lawn.
Build the yard where childhood happens — grass under bare feet, pets in the sun, birthday parties outside, and a landscape supported by water your family already produces from showers, baths, and laundry.

Start With a Smarter Landscape PlanMany homeowners still want lawns, shade trees, gardens, pets, and outdoor spaces for family life. But water costs, drought cycles, and restrictions make traditional landscape planning feel risky. IrriGRAY is designed for homeowners who want to plan smarter from the start.
Every day, homes produce graywater from showers, baths, bathroom sinks, and laundry. With the right plumbing and irrigation design, that water can be reused below the surface to support landscape irrigation instead of being wasted.
System design and approved uses depend on local codes, site conditions, and professional installation requirements.
Beautiful turf is possible, but it should be planned properly. Subsurface dripperline typically needs to be installed beneath the lawn area at close spacing — roughly every 18 inches. For existing lawns, that can mean removing turf, preparing the soil, installing dripline, regrading, and then seeding or laying sod.
That's why IrriGRAY is strongest when included in a new landscape or major redevelopment plan — the work is already happening.
Planning a new lawn or full landscape? Let's talk early."The best time to plan graywater is before the plumbing is closed and before the landscape is installed."

Visit WaterReNu Technical SiteSometimes, but it is usually not a simple retrofit. Proper subsurface drip installation can require significant lawn removal, soil preparation, regrading, and re-seeding or sod. IrriGRAY is best considered during new construction, major remodels, or full landscape redevelopment.
The best time to design graywater reuse is before the plumbing is closed and before the landscape is installed. If you want a beautiful outdoor space without ignoring California's water reality, IrriGRAY may be worth considering early.
