Emergencies and alerts

If this is a water emergency please call
1-866-403-2683 any time.

Water emergencies may include: No water service, broken hydrants, main breaks, flooding in the street or other EBMUD water-related emergencies. Temporary water outages and traffic delays may occur when crews repair or replace a pipe or other infrastructure.

When repairs are made in your neighborhood, you may want to flush your home faucets. Once water service is restored, turn on your front hose bib – the outdoor faucet at the front of the house – until the water runs clear. Also run cold water from the faucets inside your home for 1-3 minutes until clear. Read more about what to do when EBMUD crews are in your neighborhood


Changes to taste and smell of water

EBMUD's Orinda Water Treatment Plant is now back online following the successful completion of critical upgrades.

Sierra mountain water is now coming back to the taps of many East Bay customers. As with similar operational changes throughout the year, customers may experience a difference in taste and smell as they receive the usual Mokelumne River source water.

EBMUD makes operational changes throughout the year to manage water supplies, adjust for customer water demands and to accommodate maintenance projects. Operational changes – when we shift deliveries from water supply sources or reservoirs – can occasionally change the taste and smell of your tap water.

Since the shutdown of the Orinda Water Treatment Plant last November, to ensure uninterrupted water delivery, customers west of the Oakland hills had received source water from our local Bay Area Reservoirs treated at the Sobrante, San Pablo and Upper San Leandro Water Treatment Plants.

In operation since 1935, the Orinda Water Treatment Plant is the heart of EBMUD’s system. Much of this critical $22 million project was comprised of work done underground, invisible to customers. This complex work improves the reliability of the Orinda Water Treatment Plant by adding backup power systems, upgrading water treatment processes and improving treatment configurations to allow easier maintenance during plant operation. By investing in the upgrades now, EBMUD can keep maintenance costs down in the long run and keep water flowing to our customers.

Regardless of reservoir source or operational adjustment, all customers receive high-quality drinking water that meets or surpasses all state and federal regulatory requirements. EBMUD's laboratory tests every day to ensure that water quality meets EPA and state standards.


EBMUD continues to monitor the landslide area for movement. In preparation for the rainy season, tarps were placed at the site to reduce water flowing into the landslide area. Anyone owning property in this area is responsible for and encouraged to take necessary steps to monitor their property. Read more
