OPWS Water Conservation

Drought tolerant landscape

Water Conservation Hotline: (888) 605-7317


Although the State’s water supply conditions have improved slightly, it is important to note that the drought is not over and that Southern California in particular faces many challenges with low reservoirs and increasing water demands.  As part of a prudent plan, on May 9, 2016, the Governor issued Executive Order B-37-16 and in response the SWRCB adopted a statewide water conservation regulation that established water conservation standards. Based on these newly adopted conditions and restrictions, and minor improvements in the water supply, on May 26, 2016, the TSD Board adopted TSD Resolution No. T16-006 downgrading water use restrictions from Stage 2 to Stage 1 of the Water Shortage Contingency Plan, effective June 6, 2016.


The Water Allocation Plan implemented under Stage 2 is not applicable under Stage 1 conditions.



(Resolution T16-006)

The following water conservation measures are now in effect:

  • Limits on watering - Watering or irrigation of lawn, landscape or other vegetated area with potable water is limited to 3 days per week (Monday, Wednesday, and Friday). This provision does not apply to landscape irrigation systems that exclusively use very low-flow drip type irrigation systems when no emitter produces more than 2 gallons of water per hour, use of a hand-held bucket, a hand-held hose equipped with a positive self-closing water shut-off device, or for very short periods for the express purpose of adjusting or repairing an irrigation system.
  • Landscape watering is prohibited from 9 a.m. to 5 p.m. on any day except when using a hand-held bucket or hose equipped with a positive self-closing shut-off device.
  • Irrigation system watering is limited to no more than 15 minutes per irrigation day per station. This time limit (15 minutes) does not apply to exclusive very low-flow drip type irrigation systems
  • Obligation to fix leaks, breaks or malfunctions within seventy-two (72) hours
  • Washing down hard or paved surfaces is prohibited except for safety or sanitary conditions and only with a hand-held bucket, hose equipped with a positive self-closing shut-off device, or low-volume/high-pressure washing system.

  • Watering or irrigation of any vegetated area in a manner that causes or allows excessive water flow to run-off onto adjoining surfaces must be remedied with five (5) days

  • Operating a water fountain or other decorative water feature that does not use recirculated potable water is prohibited.

  • Residential car washing is permitted with use of a hand-held bucket and/or a hose equipped with a positive self-closing shut-off device

  • No watering during rain events or in the 24 hours following each rain event

  • Use only recycled water for construction site dust control and consolidation of backfill

  • The District may implement other prohibited water uses as determined by the Board of Directors, after notice to Customers

  • Violations will incur financial penalties and possible installation of a flow restrictor as set forth in Ordinance TSD-92

California WaterFix

The California WaterFix (formerly the Bay Delta Conservation Plan) is a part of California's overall water management portfolio. It is being developed as a 50-year habitat conservation plan with the goals of restoring the Sacramento-San Joaquin Delta ecosystem and securing California's water supplies. The California WaterFix would secure California's water supply by building new water delivery infrastructure and operating the system to improve the ecological health of the Delta. The California WaterFix would also restore or protect approximately 145,000 acres of habitat to address the Delta's environmental challenges.

Calleguas Municipal Water District has assembled a series of web links to videos, fact sheets, and other materials that offer extensive information about the California WaterFix. Click here to visit that page.
