Project Overview
The Wylie Water Treatment Plant consists of four individual plants at one location.
- Wylie WTP I (70 MGD) Built in 3 Phases: 1956-1965; Upgraded 2020
- Wylie WTP II (280 MGD) Built in 4 Phases: 1972-1988
- Wylie WTP III (280 MGD) Built in 3 Phases: 1995-2003
- Wylie WTP IV (140 MGD) Initial Phase Built in 2008
Currently, we have several different projects taking place as we expand and upgrade our plants.
PLANT I REHABILITATION & UPGRADES
WHY: Project rehabilitated the 65-year-old water treatment plant and brought it up to modern standards, fully utilizing the capacity of existing storage at the Wylie Water Treatment Plant
WHAT: Work included constructing two new 35 MGD flocculation/sedimentation basins, rapid mix station, pumping units, and pipelines, rehabilitating the pump station and replacing the junction gates, influent gates, and isolation valves
WHERE: Located at the NTMWD Water Treatment Plant in Wylie
WHEN: Substantial completion in September 2020. Final completion took place in March 2021.
HOW MUCH: $21 million
PLANT II FILTER REHABILITATION
WHY: Improved the water treatment filtration process at Plant II and converted the system to Biologically Active Filters (BAF) to improve water quality
WHAT: Install biologically active filters; Replace 55 valves ranging from 12-36 inches in diameter; Replace filter underdrains; Install deeper filter media; Raise wash water troughs and gullet walls; Sandblast and coat filter walls
WHERE: Located at the NTMWD Water Treatment Plant in Wylie
WHEN: Construction started in Dec. 2014. Completion expected through phased approach in 2021.
HOW MUCH: $15.6 million
PLANTS I & II SLUDGE HANDLING IMPROVEMENTS
WHY: Rehabilitated our 37-year-old sludge handling pump station and brought it up to modern standards and improved functionality
WHAT: Rehabilitate pump station; Install new submersible pumps, lagoon discharge lateral, suction and discharge piping; Replace discharge valves on existing sludge lagoon laterals; upgrade electrical instrumentation
WHERE: Located at the NTMWD Water Treatment Plant in Wylie
WHEN: Construction completed in 2018.
HOW MUCH: $1.8 million
PLANT IV EXPANSION
WHY: Increased treatment capacity for the regional water system to meet future water demands
WHAT: 70 MGD expansion project increased total treatment capacity to 840 MGD; New pumped rapid mix facilities; New flocculation and sedimentation basins; 10 new filters; New ozone disinfection facility; Additional chemical storage and feed facility
WHERE: Located at NTMWD Water Treatment Plant in Wylie
WHEN: Substantial completion in November 2020.
HOW MUCH: $87 million
