Water Conservation

Winning video - 2011 Water Awareness High School Video Contest

The City of Thousand Oaks asks you to conserve water usage inside and outside your home.

Southern Californians need to recognize that they live in an arid region and that growing demands for water require all water users to efficiently use this resource. Record dry weather can dramatically decrease runoff from the Sierra Nevada snowpack which is where our water originates. As well, environmental concerns in the Sacramento-San Joaquin Delta restrict the ability to transport water.

On June 5, 2009, a new Water Conservation Ordinance went into effect. View the City's Conservation Public Service Announcement.

What are the basics of the City of Thousand Oaks permanent water conservation measures?

  • Watering is prohibited between the hours of 9:00 a.m. and 5:00 p.m.
  • Watering duration is limited to no more than fifteen minutes per day per station
  • No excessive water flow or runoff is permitted
  • No washing down hard or paved surfaces
  • Leaks, breaks or malfunctions must be fixed within 7 days of receiving notice
  • Re-circulating water required for decorative water fountains and features
  • Washing vehicles, other than at commercial car wash facilities, must be done with a self-closing shut off nozzle on the hose
  • Drinking water in food establishments served only upon request
  • Lodging establishments must provide guests options to decline daily linen services
  • Single pass cooling systems may not be installed
  • Non-re-circulating commercial car wash and laundry systems are prohibited in new systems. Effective 1/1/2010, ALL commercial conveyor car wash systems must have installed operational re-circulating water systems.
  • Restaurants are required to use water conserving dish wash spray valves

How is this Ordinance enforced?

The Ordinance is enforced through public outreach and education.

Excessive water use can be reported to the homeowner, HOA, or business owner.

A City Water Hotline is available to report any excessive water use. Call (805) 375-5747 or click here.

We simply must reduce our water usage. Here's how you save water:


  1. Turn off the water when you brush your teeth. Save 3 gallons a day.
  2. Shorten your showers by one or two minutes and save up to 5 gallons.
  3. Save 20 gallons a day for every leak you fix.
  4. Save between 15 and 50 gallons each time by only washing full loads of laundry.
  5. Talk to your family and friends about saving water. If everyone does a little, we all benefit a lot.


  1. Water your yard only before 9 a.m. or after 5 p.m. to reduce evaporation and interference from wind. Save up to 25 gallons a day
  2. Save 40 gallons a day by installing a smart sprinkler controller.
  3. Mulch! Save hundreds of gallons a year by using organic mulch around plants to reduce evaporation.
  4. * Use a broom instead of a hose to clean driveways and sidewalks. You'll save 150 gallons each time.
  5. * Check your sprinkler system for leaks, overspray, and broken sprinkler heads, and save 500 gallons a month.
