CLARKE AVE LIFT STATION BYPASS. Public Works

The City of Spokane contracted for a temporary bypass pumping system to allow the Clarke Avenue lift station to be taken offline for electrical switchgear replacement. The scope includes design, delivery, installation, testing, commissioning, de‑commissioning, and removal of a turn‑key bypass pumping system capable of handling 2‑6 MGD at a 114 ft static head, with two primary variable‑speed pumps and one standby pump, all supported by HDPE piping and associated controls. The contract is a unit‑price/lump‑sum arrangement with separate line items for the system, operation days, and standby service, and requires compliance with Washington state prevailing‑wage rules, insurance, bonding, and a 3 % M/WBE subcontracting goal.
