Council awards $4.74 million contract for PTA upgrades at wastewater plant
Summary
The council approved a $4,735,820 contract with GDC Industrial for PTA improvements at the town wastewater treatment plant, citing repeated equipment failures, obsolete parts, and safety upgrades including H2S detection. Staff projected substantial completion in winter 2028 pending material lead times.
The Flower Mound Town Council unanimously approved awarding the Wastewater Treatment Plant PTA Improvements Project to GDC Industrial for $4,735,820, the lowest qualified bidder.
Manny Palacios, assistant director of public works operations, outlined the scope: replacement of mechanical fine screens and associated washer/compactors, grid pumps and motors, deteriorated piping and chutes, PLC and electrical upgrades, a protective canopy, and an H2S gas detection system for worker safety. Palacios said the PTA was constructed in 2000, processes an average of about 5,000,000 gallons per day (peak 33,000,000), and has logged over 90 unscheduled work orders in the past 15 years.
Palacios noted that the town purchased replacement screens earlier in the year and that some existing screens had failed and were operating under temporary repairs. He and staff reviewed bidder references and recommended GDC Industrial, an Alvarado, Texas firm with relevant experience. “The screens are on hand,” Palacios said; the project schedule calls for an award this month, notice to proceed in August, and a contract timeline targeting substantial completion in winter 2028 and final completion in spring 2028, subject to material lead times.
Council members asked whether the new equipment would be more standardized and easier to service than the older German-made parts; Palacios said the new Dupont-style screens are manufactured in the U.S. with accessible parts and service.
Next steps: Staff will issue a notice to proceed after final contract paperwork and monitor materials lead times; staff will report on progress to council per standard contract oversight.
