HARKER HEIGHTS, TX — A system failure lead to 17,500 gallons of sewer overflow and a fish kill at the Trimmier Creek Tributary.

According to the City of Harker Heights, the Trimmier Creek Lift Station experienced a telemetry system failure Tuesday evening. The City says the overflow was caused when the floats and pumps did not automatically turn on.

According to the City, 17,500 gallons of sewer overflowed into the Trimmier Creek Tributary, causing a fish kill.

The City of Harker Heights says the Texas Commission on Environmental Quality (TCEQ) investgator on-site conducted dissolved oxygen samples to determine the extent of the impact. The sewer overflow was contained in a low area, per the city.

City crews cleaned and disinfected the area.

The Supervisory Control & Data Acquisition (SCADA) technician replaced the damaged float and reprogrammed additional alarms into the Lift Station controls.

The City says they will continue to monitor the floats and alarms, as well as conduct additional testing of the creek water for the next few days.
