Contract Awarded for Work at a Tyler Water Treatment Plant

TYLER – The Tyler City Council has awarded a $4,435,000 construction contract to Gracon Construction, Inc. It’s for the Golden Road Backwash Pump Station and Clearwell Baffles project. Water from the water distribution system is curretnly used as the source for filter backwash supply water. The backwash water is used to clean the rapid sand filters, which are part of the water treatment process. Once completed, the pump station, a Texas Commission on Environmental Quality (TCEQ) requirement, will pull water from the clearwells to use in the filter backwash process. Construction is expected to begin by June and will be complete by April 2018.

While the design of the pump station was underway,the city staff identified issues relating to the clearwells, which store treated water prior to distribution in the water system. Because of the configuration of the existing piping system, the chlorine that is injected into the water before it enters the clearwells tends to exit the clearwells before it has a chance to sufficiently mix with the water inside the clearwells.

“Because of the proximity of the work required for the clearwell baffling and the backwash supply pumps,” said Lisa Crossman, director of water utilities. “The design of the baffling system was added to the plans for the backwash supply pumps.”
