Pilot pipe‑lining planned for King's Beach area to reduce intermittent bacterial spikes
Summary
Staff said a pilot lining project (Simpson Street) will be included in upcoming CSO‑005 phase 1 work to test whether lining reduces intermittent high bacteria readings; success will be measured by post‑lining manhole monitoring.
Staff told the commission consultants have included quantities for a pipe‑lining pilot in CSO‑005 phase 1 designs so the crew can line a stretch (Simpson Street) in the spring/summer construction season and assess whether lining reduces intermittent high bacterial loads recorded in manholes.
Apex and consultants will establish baseline manhole readings before the pilot and compare post‑lining readings to determine whether lining yields a material improvement; staff said the pilot will inform whether a larger lining program is cost‑effective.
