Two Distinct Issues Unserved areas Areas outstripping their supply TACIR
Ballpark Estimate In 2005, $50,000 to $150,000 per mile of water line Plus operating costs. TACIR
Costs to Serve Rural Areas Reading metersvehicle costs and staff time Operating and maintaining pumps and tanksstaff, electricity, depreciation Flushing lines to ensure drinking-water quality All are more costly in sparsely populated areas. And there are fewer people to pay for them. Grants help with intial costs, but not operating costs. TACIR
TACIR Line Flushing Costly but necessary Serving freshly treated water just in time is impossible
Ways to Reduce Costs Automated meter reading reduces staff time in the field; vehicle idling, stops and starts Automatic line flushing saves staff field time and water Remote monitoring of tanks, pumps and valves saves time, water and money But its still more expensive in sparsely populated areas.
