Water mainline replacement involves excavation, installation of water main, valves, fire hydrants, service lines, backfill and restoration.  Projects are identified based on decision factors which include inadequate fire flow demand, water quality, and the amount of fails (leaks) per foot of pipe. Each budget year main line projects are re-evaluated by staff to determine which projects are best suited for the fiscal year and fit the budget.
