Restricted Uses of Potable Water

With improved local water supplies, DSRSD has suspended mandatory water-use limits and certain restrictions. Customers must still follow state and local regulations that prohibit wasteful and unreasonable uses of potable water.*


All Customers

Irrigation must not cause runoff onto adjacent property, non-irrigated areas, walkways, roadways, parking lots, or structures.

Do not irrigate while it’s raining or for 48 hours after measurable rainfall.

If you use a hose to wash a vehicle, the hose must have a quick-action shut-off nozzle.

Do not use potable water to wash down driveways and sidewalks.

Do not use fountains or other decorative water features unless they recirculate the water or use recycled water.

Do not water ornamental turf in public roadway medians except with recycled water.

Homeowner Associations

Do not take action against property owners who reduce or eliminate landscape watering.


Wait to serve water until a customer requests it.

Hotels and motels

Give guests the option of not having linens laundered daily and prominently display this information in each guest room.


Comply with irrigation regulations established by the California Building Standards Commission and the Department of Housing and Community Development for new homes and other buildings.

Use recycled water for grading and compaction, wetting pads, dust control, and sewer flushing. Recycled water is available from hydrants and at the water recycling plant in Pleasanton. Potable water may be used for special construction purposes, such as fire protective coatings, special mortars, structural concrete, and for pipeline testing if recycled water is not reasonably available.
