Mandatory Water Use Restrictions

The Drought Alert restrictions are in addition to permanent mandatory restrictions in place. Permanent restrictions are listed at the bottom half of this page.

Please Limit Outdoor Irrigation to Two Days Per Week

The City of San Diego is strongly urging residents to further reduce their outdoor water use by reducing their outdoor irrigation of lawn and landscaped areas to no more than two days per week, for five minutes per watering station. With the state mandate that the City of San Diego reduce its water usage by a collective 16%, the quickest and most effective way to achieve this reduction is through reducing outdoor irrigation, which accounts for more than 50% of residential water use.

Recommended Watering Schedule

The City of San Diego is strongly urging you to water no more than two times per week, for five minutes per day, based on the following suggested schedule:

Time limits apply to standard sprinkler systems.

NOTE: The 5-minutes-per-day time limit does NOT apply to landscape irrigation systems using water-efficient devices, including drip and micro-irrigation systems and stream rotor sprinklers. However, these water-efficient systems should follow the two-day-per-week schedule.

Permanent Mandatory Restrictions

Permanent mandatory restrictions have been in place since 2011, and apply year-around, whether the City is in a drought or not. These restrictions are designed to promote water conservation as a permanent way of life in San Diego.

  • City of San Diego water customers must prohibit excessive irrigation and must immediately correct leaks in their private water systems. The City's regulations state that customers "shall not allow water to leave their property due to drainage onto adjacent properties or public or private roadways or streets or gutters due to excessive irrigation and/or uncorrected leaks."
  • Customers shall repair or stop all water leaks upon discovery or within 72 hours of notification by the City of San Diego.
  • Customers cannot use a running hose to wash down sidewalks, driveways, parking areas, buildings, awnings, windows, tennis courts, patios or other hard surface areas, except to alleviate immediate safety or sanitation hazards. A water-efficient device, such as a commercial water broom, must be used and all wash water must be prevented from entering the storm drain system (curb gutters, streets, alleys, and inlets).
  • Overfilling of swimming pools and spas is strictly prohibited.
  • All decorative water fountains must use a recirculating pump.
  • Residents washing vehicles (automobiles, trucks, trailers, boats, RVs) must implement procedures to conserve water and prevent excessive runoff, such as:
    • Washing vehicles at a commercial car wash.
    • Washing vehicles on a lawn or pervious surface or directing water flow to a lawn or pervious area.
    • Damming wash water for collection and disposal to a pervious area or to the sanitary sewer.
    • Using a hose with an automatic shutoff nozzle.
    • Using a hand-held water container.
  • The City will not provide new water service connections for customers using single pass-through cooling systems.
  • All new conveyer car wash and commercial laundry systems connections will be required to employ a recirculating water system.
  • Restaurants and other food establishments shall only serve and refill water for patrons upon request.
  • Guests in hotels, motels, and other commercial lodging establishments will be provided the option of not laundering towels and linens daily.

These restrictions apply to those whose property lies within the City of San Diego Public Utilities Department's service area. If you receive your water bill from a different agency, please check with that agency regarding any applicable water use restrictions.
