2020 Program Information
The Alameda County Water District (ACWD) is scheduled to clean a selection of water mains in the cities of Fremont, Newark and Union City, and all dead-end mains in the Tri-Cities to improve water quality and remove sediment buildup in pipes that may cause discolored water. This is part of the vital service provided by ACWD to ensure that all customers receive high quality water.
Cleaning will occur at various locations throughout the service area from January through June 25 2020; Monday through Friday, from 7 a.m. to 4 p.m. (excluding holidays).
Please note that there may be some sediments stirred up in the water during or immediately after the Main Cleaning event, giving the water a cloudy or discolored appearance. The water remains safe to drink (see discolored water FAQs). Customers may experience discolored water if streets or cul-de-sacs in their immediate area are being cleaned. Please minimize water use and avoid washing light-colored laundry from 7 am to 4 pm on the day main cleaning is scheduled for your neighborhood or if discolored water is noticed.
