The Sewerage Agency of Southern Marin launched their 2-year, $20 million Waste Water Treatment Plant (WWTP) rehabilitation project in April 2018. Improvements include infrastructure modernization, increased reliability and efficiency, electrical upgrades, and odor reduction.
Competed work at the WWTP project during the past 3 weeks includes the following:
The next 3-week look ahead involves demolishing the existing odor control system, replacing several key isolation valves and water control gates, installing a 4,000 gal above-ground diesel fuel tank pad, and continue running electrical conduit from motor control centers to equipment and pumps. In addition, concrete repairs to primary clarifiers bays #1 and #2 and a specialized 120 mil thick coating system will be applied to the Headwork’s influent wet wells and channels. Tricking filter #2 replacement work is scheduled to commence in late June. Work continues to progress on schedule in within budget.
Workers poured a 30ft x 30ft concrete pad to support the odor control supply fan system.
Workers removed the mechanical screen bar system and sandblasted the influent channel #2 located within the headworks building.
Work crews installed a 3 MGD multi-cloth disk filter to provide additional filtration of plant’s treated effluent water.
