Pipeline Replacement Program (Feb 28, 2017)

MVWD is currently undertaking a pipeline replacement program in order to replace water lines that have reached the end of their service life. While pipeline contractors are working to make these upgrades, customers may experience periods of reduced water pressure and/or discolored water.

The District will make every effort to notify residents affected by pressure reduction at least 48 hours prior to the disruption. Discolored water is typically the result of system valve operations during construction and is a necessary part of joining the upgraded portions of the system to the existing system. Water quality will not be affected and is still safe to drink.

Every effort is made to limit the areas affected by discolored water through system flushing activities but often sediment is deposited past the main water system and into the customer's service line. If you discover discolored water in your home, it is recommended that you access the faucet furthest from the water meter (typically a backyard hose bib), and turn it on fully for 2-3 minutes. If the water still appears discolored after running it, please contact the District's Operations Superintendent, Hank Aceves, at 909-267-2185 as additional system flushing efforts may be necessary
