EMWD works diligently to deliver safe and reliable drinking water to its customers. This effort begins with protecting our water supply sources – such as groundwater wells – and continues through the entire treatment and distribution process until the water reaches the meter. However, some hazardous conditions may exist on customer properties, which risk that safe drinking water supply.


Additional Information About Tap Water

The availability of clean, safe, healthy drinking water is something most of us take for granted. The water that flows from your tap is more than just a convenience; it contributes to the quality of life that we all enjoy. A well maintained water system is critical to public health, fire protection, and comes at a value that can’t be beat when compared to bottled water.


Lead and Copper Service Line Study
Revised Lead and Copper Rule - Identification of Pipe Material

In accordance with the new Federal regulations and guidelines released on August 4, 2022, Eastern Municipal Water District (EMWD) is conducting a lead and copper service line study throughout its service area. 

Previous studies have indicated that EMWD customers are not at risk; however, the United States Environmental Protection Agency (USEPA) and the State Water Resources Control Board’s Division of Drinking Water require that lead pipelines on the customer side of the water meter, built prior to 1986, be identified.

EMWD water service lines are not made of lead. However, the water service line on the customer’s side of the water meter may be made of lead or steel. Lead may also be found in older brass fixtures, valves, or solder, where pipes are joined. 

If your residence/service address was built prior to 1986, it will therefore be included in the pipe material survey.

NOTE: Throughout 2024, EMWD staff will be on site conducting the material survey at the service meter.
