WES plans $70M wet-weather program to boost Tri City peak capacity from 70 to 105

Jeff told the committee the wet-weather program is a combined effort of three projects with an overall value of about $70,000,000 and a primary goal of increasing Tri City facility peak capacity from 70 to 105 to operate only during high-flow rain events. "It's around $70,000,000 for the 3 projects," he said, and explained the program packages treatment upgrades with site work (relocating large-vehicle parking and reusing landfill property) and an administrative remodel to repurpose garage space into offices.

Jeff said staff are finalizing scoping with a consultant and expect to bring the program to the WES board for approval; if approved, work would begin in October on scoping and subsequent design activities. He emphasized the wet-weather components will come online only during peak storms and will be sequenced with landfill and parking mitigation work to account for construction impacts.
