Rainwater expert to speak Feb. 23 at Del Mar Powerhouse


Did you know that 1 inch of rain on an 1,800-square-foot roof will yield about 1,000 gallons of water?

Candace Vanderhoff, architect and CEO of RainThanks & Greywater, will speak on “Rainwater Harvesting” at 9:30 a.m. Feb. 23 at the Del Mar Powerhouse.

Vanderhoff will discuss the wide range of systems and strategies to capture rainwater that falls on your property. She will cover how to calculate the amount of rainwater you can capture, what system is right for your property, and how to manage overflow in rain gardens and bioswales. She will also briefly introduce how to divert graywater from showers and laundry to be used as irrigation in the landscape.

The public is invited to this free presentation sponsored by the Del Mar Garden Club.

Vanderhoff has a master’s degree in architecture from the Southern California Institute of Architecture, is certified as a LEED Accredited Professional by the U.S. Green Building Council, and holds two Permaculture certificates: EarthFlow Design and Center for BioRegional Living. She has specialized training from Greywater Action, Green Plumbers USA, and American Rainwater Catchment System Association.

Vanderhoff lectures and consults on regenerative living with a focus on rainwater harvesting, graywater reuse and designing edible food forests that provide organic food for property owners and lush habitats for native butterflies and pollinators.

Vanderhoff has made San Diego her home since 2000. Since then, she has been actively involved in projects that conserve water, grow food, create human shelter, and teach simple green living. Her company RainThanks & Greywater is a leading water-harvesting consulting firm with more than 100 projects installed in San Diego County. She is also executive director of Las Casitas, a 501(c)3 public benefit corporation. Since 2013, the Las Casitas Water Weaver’s Project has collaborated with “local non-profits, water districts, and schools to raise awareness and offer solutions on the importance of capturing and reusing our region’s precious water.”
