RVSD highlights force-main study, smart-cover pilot and siphon maintenance in operations report
Summary
Operations staff reported on a coordinated overnight shutdown with CMSA, a force-main routing study to be cost-shared with an Oak Hill developer, pilot smart-cover monitoring for ARV vaults, and ongoing Ross Commons siphon condition assessment work; staff also reported June as a no-spill month though year-to-date spills totaled 12.
Operations and maintenance staff presented routine but consequential infrastructure updates to the board on July 15, including asset assessment work and pilot monitoring projects.
Staff described a kickoff of a force-main routing study (paid 50% by the Oak Hill developer, 25% by RVSD and 25% by Sanitary District 2) estimated at about $34,000 to inform easement access and replacement options. The pump station crew coordinated an overnight full-system shutdown with CMSA to inspect the Headworks influent channel and perform a gate-valve replacement; no major incidents were reported.
O&M staff also described a smart-cover pilot to detect vault-level rises for early spill detection, potholing and electromagnetic testing for a 54-inch force main, and targeted maintenance on the Ross Commons siphon to remove calcified debris. Staff noted June had no waterway-reaching spills; six small (Category 4) incidents were reported that did not reach waterways, and additional incidents traced to external flood events.
