California's Emergency Drought Regulations continue...

The Department of Water Resource, under the direction of the Governor, has extended the Emergency Drought Regulations. Despite recent rain and snow, most of California is still experiencing severe drought. Residents are urged to continue their conservation efforts. Calistoga conserved a total of 14% in 2014 and 18% in 2015 over 2013 water usage. Let's continue to conserve!

Water Conservation Tips

Conserving water is easier than you think. Let’s work together to reach our 20% water use reduction goal by individually taking action. Here are 5 simple actions every Calistogan can take to reduce their water usage:

water conservation accessories
  1. Limit shower time to 5 minutes
  2. Don’t let water run while shaving, brushing teeth, or rinsing dishes.
  3. When washing hands, don't let the water run while lathering.
  4. Listen for dripping faucets and toilets that flush themselves. Fixing a leak can save 500 gallons each month.
  5. Run the dishwasher and clothes washer with full loads only.

You can also pick up a FREE Water Conservation accessories (low flow shower head, bathroom and kitchen faucet aerators, water displacement bag for the toilet, leak detection dye tabs, pipe tape, garden hose shut off valve nozzle, and shower timers) from Public Works. Posters and other educational materials are also available by request.

California Model Water Efficient Landscape Ordinance

In California, about half of the urban water is used for landscape irrigation. The Department of Water Resources (DWR) has updated the Model Water Efficient Landscape Ordinance to increase water efficiency standards for new and retrofitted landscapes through more efficient irrigation systems, greywater usage, onsite storm water capture, and by limiting the portion of landscapes that can be covered in turf. 

  • New construction projects with an aggregate landscape area equal to or greater than 500 square feet requiring a building permit
  • Rehabilitated landscape projects with an aggregate landscape area equal to or greater than 2,500 square feet requiring a building permit
