Wastewater Treatment Facility Overview

The City of Norman Wastewater Treatment Facility (WWTF) provides treatment to wastewater generated by a population of over 100,000. Originally constructed in 1942, the facility has undergone additional significant facility upgrades during 1957, 1963, 1972, 1986, 1990, 1999 and 2004.

Currently, the facility’s secondary treatment capacity is designed for an average flow of 12 million gallons per day (MGD), a sustained wet weather flows of 15 MGD and a maximum daily flow of 30 MGD.

The Oklahoma Department of Environmental Quality (ODEQ) administers the issuance and enforcement of municipal discharge permits, known as Oklahoma Pollution Discharge Elimination System (OPDES) permits. The United States Environmental Protection Agency (USEPA) however, maintains oversight rights for ODEQ’s water quality programs.

The City of Norman Wastewater Treatment Facilities is required, as part of the OPDES permit to routinely monitor effluent water quality and report conventional pollutant loading on Norman’s segment of the Canadian River (receiving stream). These monitoring reports are called Discharge Monitoring Reports (DMR) and are required monthly for treated effluent and annually for biosolids treatment and agricultural land application..
