Water Wise Davis, a working group of Cool Davis, is partnering with the City of Davis to host a third annual Greywater Showcase in the Davis Senior Center Valente room at 646 A Street in Davis on Wednesday, July 24, from 6:00pm to 800pm. This year’s theme is case studies, shining a light on what systems look like as installed in a home. At last year’s event, Mayor Pro Tem Gloria Partida opened the event with inspirational encouragement.

This year’s Greywater Showcase will be opened by City of Davis Councilmember Dan Carson with a follow-up from Dawn Calciano, City of Davis Conservation Coordinator, who will update us on per capita water consumption data and new resources like AquaHawk for monitoring water usage at the household level.

Next, Leslie Crenna of EcoAssistant, as for previous years, will deliver a short presentation about water reuse, the potential for greywater in our community, and the two basic types of greywater systems.

Finally, several presentations will be made featuring in-depth information about particular installations here in Davis — case studies. A combination of service providers and home owners will share images of their systems and tell the story of how they decided upon a system, how the install went, and how the system has performed.

After the presentations, participants will have the opportunity to peruse model systems, and chat with system owners, Water Wise Davis members, service providers, and City of Davis building department and public works staff. Once again, our dedicated Chief Building Official, Greg Mahoney, will be on hand to answer code questions.

Be sure to access the Senior Center via the A Street entrance. If you use the 7th Street entrance, turn right down the hall and then left to the end of the hall for the Valente room.

This event is FREE!

In California, greywater is defined as water collected from washing machines, sinks (excluding the kitchen sink), showers, and bathtubs that can be used for landscape irrigation. Greywater systems may help reduce household water usage especially in summer by reducing the use of potable water for outdoor irrigation. City and state level code and ordinance uses a different spelling: “graywater.”

The easiest and permit free system is a “laundry to landscape” system that directs drainage water from your clothes washing machine to your landscape. The next level requires a bit more commitment of time and resources: a “branched drain” system directs drainage water from showers, bathroom sinks, and tubs to your landscape and requires a permit. Hopefully, indoor reuse systems will also be represented at the showcase.
