Statewide Water Use Restrictions -

What You Need to Know

Last week, the State Water Resources Control Board adopted an emergency regulation, activating new water rules for California commercial, industrial, and institutional properties. Here are the restrictions you should know and our tips to make them easier.

Commercial, industrial, and institutional properties statewide cannot irrigate non-functional turf with potable water.

Non-functional turf is any grass that is purely decorative and is not used regularly for recreation or community/civic events.

Non-residential property owners should work with their landscaping professionals to turn off any irrigation stations that are dedicated to non-functional turf. If non-functional turf and trees are irrigated by the station, cap the sprinklers that irrigate the lawn areas. Trees take decades to replace and should still be irrigated during droughts.

Property owners are encouraged to consider replacing their non-functional turf with low-water landscaping during this fall’s planting season. Not only will it improve your property’s appearance during our current drought, but it will permanently lower your water use. We are offering rebates up to $6,000 for replacing turf with low-water landscaping.

Functional turf and non-turf landscaping can only be irrigated with potable water on the property’s approved watering days.

Properties with odd-numbered street addresses can only water on Mondays, Wednesdays, and Fridays. Properties with even-numbered street addresses can only water on Tuesdays, Thursdays, and Saturdays. Properties with no street number are limited to watering a maximum of three non-consecutive days per week. Additionally, sprinkler irrigation is not permitted between 9:00 a.m. and 6:00 p.m. Make sure your landscaping professionals are aware of these restrictions.

Irrigation water cannot run off into a nearby property or pavement.

Ask your landscaping professionals to inspect your irrigation system a few times per year to repair any broken, bent, or misaligned sprinkler heads.

Landscaping cannot be irrigated during or within 48 hours after receiving 0.25” or more rain.

Upgrade your irrigation controller to a weather-based model that will automatically shut off during rain. Rebates up to $3,000 are available.

Vehicles washed with a hose must have an automatic shut-off nozzle.

Provide employees with hose nozzles or wash vehicles at a commercial carwash.

Washing hardscapes such as sidewalks, driveways, buildings, patios, or parking lots with potable water is only permitted when public health and safety are at risk.

Ask employees to sweep or leaf blow hardscapes instead.

Potable water can only be used in fountains and other decorative water features if the water recirculates.

If your property has a decorative water feature that does not recirculate water, shut it off until the drought has ended. If your water feature does recirculate, consider posting signage to inform customers and passersby.

Potable water cannot be used for street sweeping and construction uses, unless there is no other method that can be used or if it’s needed to protect public health and safety.

Customers can request recycled water meters to use for construction by calling our Utility Billing Division at (925) 960-4320.

Patterson Pass Water Treatment Plant Upgrades Complete

Zone 7 Water Agency has completed upgrades to its Patterson Pass Water Treatment Plant, doubling the amount of water it can treat per day and improving the quality of the drinking water it produces. This treatment plant purifies water from the South Bay Aqueduct before Livermore Municipal Water delivers it to your property.

Treating water from the South Bay Aqueduct has become increasingly difficult because of higher organic matter levels and more frequent algae blooms, which cause taste and odor issues. By replacing chlorine with ozone as the main disinfectant at the treatment plant, your water will now be cleaner, safer, and better tasting.
