Edmond Public Works Authority

View all


The Edmond Public Works Authority (Authority) located in Oklahoma County serves 32,648 sewer customers and 31,179 water customers. According to the 2010 U.S Census the population was 81,405.

The Authority’s current treatment process is extended aeration. The design average daily flow is 16 MGD, and the receiving waterbody is Coffee Creek which is not on the 303(d) list.

The Authority developed a 2013 Master Plan to address their water and sanitary sewer systems. The existing sanitary sewer collection system consists of 15 sewer basins with a network of gravity collection pipes, pumps and force mains that collect and transport wastewater to the Coffee Creek Wastewater Treatment Plan. The Master Plan recommends a number of collection system improvements to provide the hydraulic capacity needed for the future. The Authority is also under consent order for unpermitted discharges.

To address these issues the Authority will use the funds to construct approximately 3,000’ of 54-inch and 12,850’ of 42-inch sanitary sewer lines to replace an existing 24-inch interceptor along Coffee Creek in northeast Edmond.

These improvements will enable the Authority to more effectively reach its growing number of residents and provide reliable transportation of wastewater to the Coffee Creek Wastewater Treatment Facility (WWTF).
