Water Maintenance

More than 37,000 homes across Bellevue’s service area are connected to the city’s over 600 miles of pressurized water main. Bellevue’s drinking water system is complex due to its topography, which ranges from 20 feet above sea level on the shores of Lake Washington to over 1,400 feet above sea level near Cougar Mountain.

The Utilities Department maintains its water infrastructure – which includes pipes, reservoirs, pump stations, pressure zones and fire hydrants – through regular maintenance, repair or rehabilitation, and replacement. Through the city’s progressive watermain replacement program, we replace about five miles of water pipeline each year, which helps to keep our water main breaks well below the national average.
