Water Quality FAQs

System leaks vary according to size, location and potential water loss. The District records all reported leaks and responds to those that pose the most damage and water loss first. Systems are inevitable due to normal wear and tear of water lines, tree roots and changes in temperature.

You can help protect all of our groundwater supplies by disposing of harmful household products and other toxic chemicals in the proper manner. Household hazardous waste includes cleaners, glues, soaps, pesticides, paints, fertilizers, medicines, chrome solutions, motor oil, and batteries. These waste materials should never be dumped down the drain, in the trash, or on the ground. Instead they should be taken to a hazardous waste collection or recycling center. Whenever possible, cutting down on the use of toxic household products by switching to safer alternatives is encouraged.

Household hazardous waste should be taken to the San Bernardino County Fire Household Hazardous Waste Collection Facility at 2824 East “W” Street (located at the former Norton Air Force Base). It is open Monday through Friday from 9 a.m. to 4 p.m. For more information on household hazardous waste, call 1-800-645-9228.

Join us in preserving our water resources by using water resources wisely and efficiently. This will ensure a long-term supply of clean, safe water. Remember, preventing water contamination is less expensive than developing new treatment methods.

Contact the Customer Service line during regular business hours to request a pressure check at 909-889-9501.

Water pressure can fluctuate due to higher-than-normal demand placed on the water system. This usually occurs during the summer months, when water usage is at its highest level. In some instances, depending on location, customers may experience a change in water pressure due to the increased number of wells and boosters operating to meet water demand during peak usage times. If you have any questions or concerns regarding your water pressure, contact our Engineering Department at 909-888-8986.

On a daily basis, our District Water Quality Department samples water from water sampling stations located throughout the district. These samples are sent to an independent laboratory for analysis, thereby insuring that East Valley Water District is providing the best quality water available. In addition, the District’s Water Quality Department personnel flush our water systems through selected fire hydrants on a regular basis. This periodic flushing helps eliminate the possibility of stagnant water conditions.

Similar to flushing your home’s pipes from debris that may collect over time, the District flushes fire hydrants by allowing water to run for short period of time. This process is known as hydrant flushing and it is an important element for the maintaining a healthy water system. By allowing water to travel out of the hydrant at a high speed and pressure, pipes are cleaned of natural debris that accumulates in the pipeline. 

To flush a fire hydrant, staff opens the hydrant and allows water to flow out uninterrupted for 5-10 minutes.

As part of our efforts to maintain and continue providing reliable services, pipes need to be flushed regular to prevent water from remaining stagnant in the pipes for an extended period, and clear pipes from natural deposits that may accrue over time.

Water services will not be interrupted during pipeline flushing, but customers may notice lower water pressure while it is taking place.

After flushing has been completed in your area, we recommend running a faucet for about two minutes or until water runs clear. This will help clear your home’s pipes of any leftover debris.

We encourage you to collect this water and use it to water plants instead of letting it run down the drain. For more information about the flushing program or to report discolored water conditions that have not cleared up within 24 hours after flushing activity, please contact our Water and Wastewater Compliance Supervisor at (909) 806-4222.

Typically running the cold water for 2-3 minutes will usually flush your pipeline enough for the water to once again run clear.
