As wastewater and water utility rates continue to increase faster than the inflation rate, ratepayers are increasingly saying that their bills are unaffordable. With that in mind, Affordability of Wastewater Service provides an overview of the problem of affordability and offers some specific considerations that elected officials, utility managers, and utility staff might take into account when addressing affordability issues in their communities. In addition to tackling issues of how to define and measure affordability, who might be the primary targets for an assistance program, and what features might be included, Affordability of Wastewater Service offers case studies from communities that have been leaders in implementing innovative affordability programs.
