The average customer in the Pittsburgh Water and Sewer Authority [PWSA] service area spent about 2.7% of their income on water and sewage. The Environmental Protection Agency considers water and sewage bills above 4.5% to be unaffordable. But in a third of the city’s neighborhoods, at least one in every five customers was spending 10% or more of their income on water and sewage, according to PWSA’s own affordability study in 2019.
