County sanitation district outlines $3.1M Santa Anita sewer rehab in Temple City
Summary
Los Angeles County Sanitation District presented a cured‑in‑place sewer rehabilitation project on Santa Anita Avenue affecting about 3,400 linear feet in Temple City, with construction estimated at $3.1 million, daytime work and limited temporary service interruptions starting in mid‑October.
Representatives from the Los Angeles County Sanitation District briefed the Temple City City Council on a planned sewer rehabilitation project along Santa Anita Avenue that will use cured‑in‑place (CIP) lining to renew existing pipes without full replacement.
"It's about $3.1 million," said Sam Suman, the district's construction manager for the project, describing an overall district scope of about 11,817 linear feet of pipeline across roughly 47 reaches. For Temple City, Suman said the work covers about 20 reaches totaling approximately 3,400 linear feet and will include rehabilitation of manholes within city limits.
Mark Weber, the district's project manager, described the CIP process: a resin‑saturated tube is inverted or pulled into the existing pipe and cured under pressure using hot water or steam. Weber said typical cure time is two to three hours and that the technique can extend a pipe's useful life by multiple decades.
Construction will use a moving bypass (temporary pumps and a 3‑inch bypass hose) and maintain traffic flow with one lane open in each direction; crews plan daytime work—roughly 8 a.m. to 4 p.m.—and to break down bypass equipment nightly. Presenters said roughly 88 households along the route will be affected and that temporary service interruptions will be planned and communicated; door hangers will be issued at 14, 7 and 24 hours before work and portable toilets and handwashing stations will be provided to residents who request them.
Why it matters: The rehab limits disruptive full‑dig replacement while requiring temporary adjustments for residents and motorists along Santa Anita Avenue. The approach aims to reduce construction footprint and cost compared with full sewer replacement.
Next steps and timeline: Presenters said preliminary cleaning and CCTV inspections will begin before lining, CIP installs and manhole rehab are scheduled as part of the contractor's mid‑October start, with substantial completion and restoration work expected by mid‑December. The district and city staff said they will continue permitting coordination and outreach to minimize disruption.
