Frequently Asked Questions

What Is Greywater?

Greywater is lightly used household wastewater that comes from sources like showers, bathtubs, bathroom sinks, and washing machines—but never from toilets or kitchen sinks, which contain higher levels of contaminants. It’s relatively clean and can be safely reused for landscape irrigation when properly filtered and routed, helping reduce potable water use and conserve resources.

How Much Water Will I Save?

ChatGPT said:

A full greywater system—capturing water from showers, tubs, bathroom sinks, and laundry—can typically save 30–50% of a home’s total indoor water use, often amounting to 15,000–40,000+ gallons per year depending on household size and habits. By redirecting this lightly used water to irrigate plants or recharge soil, a greywater system reduces reliance on potable water for landscaping, cuts utility bills, and supports drought-resilient living, especially in arid regions.

Do I Need a Permit For A Greywater System In Austin, TX?

In Austin, permit requirements for greywater systems depend on how the system is installed. Simple, gravity-fed laundry-to-landscape systems that use existing washing machine connections and do not modify indoor plumbing typically do not require a plumbing permit, as they divert laundry water outdoors using approved components and follow Austin Water’s residential reuse guidelines. However, systems that modify indoor plumbing, reroute drain lines, include pumps or storage, or connect fixtures beyond the washing machine may require permits and inspections through the City of Austin. All greywater systems must comply with applicable plumbing, cross-connection, and water protection requirements, and additional restrictions may apply for properties located in environmentally sensitive areas.
