Approximately 63 miles of sewer main lines feed into one of three lift stations that ultimately feed into the Wastewater Treatment Plant.
The wastewater treatment plant for the City of Brownfield is a 1.4 million dollar facility built under a matching grant from the U. S. government. The Wastewater Treatment Plant was converted to a diffuser type system in 2003 at an estimated cost of $470,146. The system has a design capacity of 1,250,000 gallons per day. Average flows at the present are around 786,250 gallons per day. In addition a 32 day effluent (40,000,000 gallon) storage pond was constructed in 2003 at an estimated cost $1,113,810.
The wastewater treatment plant has a "no discharge" permit from the state which means that no effluent is discharged into a stream or lake. All of the water from the plant is used to irrigate over 585 acres of farmland which is partially owned by the City of Brownfield. The city owned acreage is leased to a private individual for farming purposes.
The treatment plant operates under Texas Commission on Environmental Quality regulations.
