NACWA’s Cost of Clean Water Index indicates increase in 2019

The National Association of Clean Water Agencies’ (NACWA) 2019 Cost of Clean Water Index, released May 29, indicates that the average cost of wastewater services rose 3.8 percent in 2019, more than doubling the rate of inflation over the same period.

The national average cost for wastewater services for a single-family residence is now $512 per year. This is the 18^th consecutive year that the increase in charges has outpaced inflation, though the increase has been more moderate – less than 4 percent – for the past few years compared to the 2004-2014 time period, during which the average increase was close to 6 percent.
