Council approves engineering contract for Golden Road filter and clarifier rehabilitation
Summary
The council approved a $1,085,100 professional services contract with Pape Dawson Consulting Engineers LLC for design work on Golden Road Water Treatment Plant filter and clarifier rehabilitation; estimated construction cost is $7.5 million with constrained phasing and multi-year timelines.
The Tyler City Council authorized the city manager to execute a professional services contract with Pape Dawson Consulting Engineers LLC in the amount of $1,085,100 to design rehabilitation work for remaining filters and clarifiers at the Golden Road Water Treatment Plant.
Water Utilities staff member Nikki described the project as a phased rehabilitation. She said the plant’s capacity is 28 million gallons per day but that aging filters have limited consistent treatment to about 22 million gallons per day. Nikki told council that filters 9, 10, 15 and 16 still have original clay underdrains from 1965 and that filter media typically needs replacement every seven to ten years. The Texas Commission on Environmental Quality (TCEQ) issued an alleged violation in 2019 requiring the city to rehabilitate clarifiers by 2027 under a compliance plan; staff said clarifiers 3 and 4 are currently being rehabilitated and that project is expected to be complete in May 2025.
Nikki outlined the design scope: removal and replacement of existing filter media and underdrain blocks, installation of surface wash systems, rehabilitation of two clarifiers including mechanical replacements and electrical/control work, and electrical improvements to address water intrusion plus a medium-voltage disconnect for high-service pumps 5 and 6. Staff estimated the construction cost at approximately $7,500,000 and described a construction window that begins after design, with bidding in February–March 2026, award in April 2026 and an approximate two-year construction period ending in April 2028. Staff also noted construction sequencing constraints that limit the number of filters/clarifiers that can be offline at the same time and long equipment lead times.
Councilmember Curtis moved to approve M2; Councilmember Nichols seconded. The motion passed on a voice vote. The council also adopted a resolution reserving the right to reimburse expenditures with proceeds of future debt as part of the action.
Council discussion included a question about whether master planning occurs regularly to avoid falling behind on maintenance; Nikki said the city performs master plans every five years to address such issues.
