- Wastewater Treatment
The City of Abilene collects and treats wastewater from users in the incorporated city limits and from:
- City of Buffalo Gap
- City of Tuscola
- City of Tye
- Hawley Independent School District
Wastewater Collection System
The wastewater collection system is a network of approximately 679 miles 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 million gallons daily (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.
Wastewater Treatment Process
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)
- Biologically Activated Filter (BAF)
- Disinfectant removal
This new system allows for up to 7 million gallons daily 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.
Industrial Pre-Treatment Program
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.
