Where Does Wastewater Go?

The City of Abilene collects and treats wastewater from users in the incorporated city limits and from the Cities of Buffalo Gap, Tuscola, Tye, and Hawley ISD.

Wastewater Collection

The wastewater collection system is a network of approximately 679 of sewer lines, 4 lift stations, and 10,070 manholes.

Sewage flows by gravity, aided when necessary by lift stations, through the collection system into the Buck Creek Pump Station, which has a rated pumping capacity of approximately 24 MGD. An emergency storage basin at this facility has a capacity of approximately 23 million gallons. 

Sewage is metered at Buck Creek and then pumped five miles to the wastewater treatment plant.

A 1987 Wastewater Collection System Analysis analyzed the system, identified inadequacies in existing and future capacities, recommended improvements, estimated costs, and proposed construction schedules. Since that time, many of the recommended rehabilitation and upgrade projects have been completed to improve carrying capacity in the system.

Wastewater Treatment


When wastewater reaches the City's Hamby Water Reclamation Facility (WRF), it undergoes full treatment which includes grit removal, Biological Nutrient Removal (BNR), aeration to encourage microbial growth with digests pollution, a Membrane Bioreactor (MBR), Reverse Osmosis (RO), Ozone, Biologically Activated Filter (BAF), disinfection, and disinfectant removal. This new system allows for up to 7MGD of highly treated reclaimed water into Lake Fort Phantom Hill to increase clean water supplies for the City. The plant also produces Type I non-potable reuse water used by local golf courses, Universities, and others for landscape purposes.

Wastewater quality is protected against industrial pollution through an Industrial Pre-Treatment program. Industrial users are required to treat wastewater to certain standards before it is released into the municipal sanitary sewer system. 

Wastewater quality is monitored at all stages of treatment according to state and federal requirements.
