The Jordan Valley Water Conservancy District issued Addendum No. 1 for the SERWTP Disinfectant Concentration-Time Improvements Project on October 19, 2026. The document provides updates to contract documents, technical specifications, and project schedules for prospective bidders.
According to the October 19 report, the project schedule has been updated. Substantial completion for the improvements is now set for March 17, 2028, or 480 days after the Notice to Proceed, whichever is later. Final completion of all work is scheduled for May 1, 2028, or 45 days after substantial completion, whichever is later.
Technical specifications within the addendum include requirements for Bluetooth-enabled functionality for transmitters and specific anode requirements. The document clarifies that magnesium anodes used in the project must be high potential and must sit at least 6 inches above the floor on 8-inch diameter PVC pipe stands. Additionally, the addendum specifies that all new underground conduits for communication pathways must be provided, as no existing spare conduits are available for use.
The addendum also addresses instrumentation and electrical requirements. While the owner will furnish PLC I/O cards, internal PLC cabinet wiring, programming, and SCADA integration, the contractor is responsible for the calibration of all field instruments. Most instruments must be purchased new, with the exception of the turbidity monitor for the 1 MG Effluent Sample Water.
The SERWTP Disinfectant CT Improvements Project involves several construction elements. Work includes the construction of new membrane baffle curtains inside the 1 MG and 3 MG buried concrete drinking water storage reservoirs, reservoir inlet pipe extensions, and recoating existing piping. The project also involves modifications to a valve vault, installation of new sample pumps, and various electrical and instrumentation upgrades.
All questions regarding the project must be submitted to Josh Curtis via email by 5:00 p.m. MST on October 22, 2026. The bid opening is scheduled for October 27, 2026, with an expected contract award in November 2026.
