Michigantown wastewater staff report bypass tests and three weekly loading exceedances

Sep 15, 2026

Operations staff reported live bypass testing during the recent groundbreaking; the plant reported three weekly loading exceedances (BOD, TSS, ammonia) when flows exceeded the plant's design capacity. Staff described bypass operations, dredging coordination and repairs underway.

The full story

Operations staff told the council that during live bypass testing conducted around the recent groundbreaking the plant bypassed flows for roughly eight hours per day. The plant submitted a report documenting three violations during the last week for maximum weekly loadings on biochemical oxygen demand (BOD), total suspended solids (TSS) and ammonia; staff attributed the exceedances to unusually high flows that overwhelmed parts of the treatment system. "We did have 3 violations. It was all for that last week of August, and it was the max loading," the operations representative said.
