Stage 4 Drought -- water supply criticalEBMUD declared a Stage 4 critical drought and set a community-wide goal to reduce water use 20 percent compared to 2013.

EBMUD customers are on track to meet our goal. We thank our customers for making water conservation a way of life in the East Bay and we ask that you keep it up!

Since conservation alone is not enough, EBMUD must supplement normal water supplies with water from additional sources. Currently, EBMUD's reservoirs combined are less than half full. Drought-related changes to our water supply operations may cause changes to the taste and smell of your tap water.

The new rainfall year began on July 1; watershed precipitation numbers are calculated from that date. 

Mandatory water restrictions in effect

What's required for everyone:

  • Shut off sprinklers and irrigation systems. Recent rains across the East Bay are not enough to end the drought, but they are enough to eliminate the need to water landscaping. 
  • No watering of ornamental turf on public street medians allowed.
  • No washing of driveways and sidewalks; except as needed for health and safety.
  • Use only hoses with shutoff nozzles to wash vehicles.
  • Turn off fountains or decorative water features unless the water is recirculated. 
  • Use of hydrant water outside the EBMUD service area is prohibited.
  • Use a broom or air blower, not water, to clean hard surfaces such as driveways and sidewalks, except as needed for health and safety purposes.

What's required for businesses: 

  • Restaurants and other food service establishments can only serve water to customers upon request.
  • Hotels and motels must provide guests with the option of not having their towels and linens washed daily.

New rates

At a public hearing on June 9, 2015, the EBMUD Board of Directors adopted new rates. Rate increases fund ongoing services and investments in our aging infrastructure. A temporary Stage 4 drought surcharge of up to 25% will pay for the costs of purchasing extra water supplies, additional conservation services and enforcement of water use restrictions.

The new rates and the drought surcharge take effect July 1. 

The drought surcharge will apply to customer flow charges until further notice. 

The average household using 10 units per month (246 gallons per day), who does not conserve, will see their bill increase by $11.65 starting July 1 under the adopted temporary drought surcharges and the regular rate increase. If conditions improve to Stage 1 or 0, the drought surcharge will be removed.  

More conservation needed 

Indoors - Strive for 35 gallons per day usageIf you already conserve, thank you. Please keep looking for ways to conserve and check regularly for leaks--silent leaks are common and use a lot of water.

Twenty percent is our community-wide goal. You may be able to save more or you may already be doing all you can to conserve indoors and out. 

How do you know if you are doing all you can? Strive for 35 gallons per person per day indoors and follow the mandatory outdoor use rules.

Conservation alone is not enough

EBMUD is delivering nearly 11 billion gallons of extra water supplies through its federal dry-year water contract – about a two-month supply to fill local reservoirs.

EBMUD continues to look for more water supplies to buy and deliver through the Freeport facility on the Sacramento River.

Excessive use and water theft must stop 

EBMUD adopted two ordinances in 2015 related to water use.

  • The excessive water use ordinance penalizes households who use 1,000 gallons per day, which is four times the amount of water used by the average residential customer.
  • The water theft ordinance allows EBMUD to fine persons for stealing water or making unauthorized use of a public fire hydrant.

How did we get here? 

In 1976-77, East Bay residents and the East Bay economy felt the pain of severe mandatory water rationing. To prevent such hardship from occurring again, EBMUD invested for more than three decades in increasing available water supplies and making conservation a way of life in the East Bay. Today, the East Bay is better prepared to cope with a severe drought than it has ever been.

Over the past 10 years, customers have reduced their water use by 20 percent.

Additionally, EBMUD has invested nearly $1 billion in the past decade on additional water supplies, recycled water projects and conservation programs. Today, thanks to ratepayer investment and customer conservation, EBMUD can handle short-term droughts better than in previous droughts.
