The project included a 5,808 square foot treatment building housing a 4-cell, 3 MGD pressure treatment vessel, a ferric chloride feed system, a chlorine generator feed system, a mezzanine, an electrical room, a control room, and a restroom. The plant included three 40x20-foot drying beds, a backwash tank, a decant pump station, a bypass valve vault, and a submersible pump wet well.

VanCon demolished the deteriorated chain & flight mechanisms in both the North and South Basins and installed new devices which included shafts, chains & flights, motors & drives, return rails, installation and start-up of electrical and instrumentation. Existing handrails were modified and permanent ladders were added. Instrumentation, controls and weather shields were installed. CM/GC additions included an extra stainless-steel platform with a retractable ladder to improve basin access, and a baffle to protect the polymer sludge rakes from being destroyed by influent water.

Sedimentation Basin Improvements
Bluffdale · Salt Lake County · 2023
VanCon remodeled existing structures to increase the capacity and prolong the life of the Bluffdale water treatment sedimentation basins. VanCon removed deteriorated chain and flight and poured seismic reinforcing concrete walls inside two basins and two buttresses outside the basins. VanCon infilled around the troughs through the effluent wall of four basins. VanCon repaired clarifiers for basins 1 and 2. VanCon installed new chain and flight and replaced pumps for six basins. The work took place through an unexpectedly extra snowy winter, requiring ice chipping and snow removal almost daily.
