The Erie County Water Authority (ECWA) is responsible for the treatment and distribution of 25 billion gallons of safe, clean, potable water annually to more than 540,000 residential, commercial, and industrial customers in 36 municipalities located within Erie County and parts of Chautauqua, Cattaraugus, western Wyoming and western Genesee counties, as well as the territories of the Seneca Nation of Indians.
As part of ECWA’s pledge to the public and its customers to operate in an open and transparent manner, we make available several publications, reports and information for public inspection and scrutiny.
