Sanitation district details $2.7 million trenchless sewer rehab affecting Temple City streets

Los Angeles County Sanitation District representatives presented plans for a $2.7 million cured‑in‑place (CIP) sewer rehabilitation that will affect approximately 2,400 feet of sewer line within Temple City.

At the council meeting the district explained CIP as “a pipe within a pipe,” describing a resin‑saturated liner that is inverted into existing pipe and cured to form a new structural interior without full trenching. The representative said the method keeps disruption to a minimum and that when sewer service must be interrupted it will be for a short duration.

The district said the project footprint inside Temple City includes about 52 manholes, roughly 18 lateral connections serving homes and businesses and one elementary school adjacent to the work area. Presenters told the council they prefer CIP over full replacement to avoid extended trenching through city streets and estimated the construction cost at $2.7 million.

District staff outlined a near‑term schedule as presented: pre‑construction CCTV and surveying on Nov. 19–20, temporary clean‑out installation Nov. 21–22, and CIP installation targeted during school closures (cited by presenters as Nov. 25–27) plus additional days around the winter holidays (Dec. 23 and Jan. 2–3). Presenters stated the installation plan totals six CIP installation days intended to limit service interruptions.

Project operations described to the council include temporary bypass pumping and portable restrooms and hand‑washing stations available to residents upon request. The district said residents will receive advance notices (14‑, 7‑ and 24‑hour notices were described) and that door hangers and website information will be printed in English, Spanish and Chinese and include a 24‑hour emergency contact.

Council members pressed staff on accessibility, repaving timelines and impacts to nearby businesses. Council Member Sternquist asked whether provided portable restrooms are wheelchair‑accessible; the district representative said he would follow up with specific accessibility details. City staff reported prior complaints about traffic delineation or cone placement on earlier projects had been addressed quickly by the district and contractors.

Council members also raised why metal plates sometimes remain after trenching work; city staff and a public works representative explained that paving is often scheduled as a larger subcontracted paving contract and plates may remain for a few weeks until repaving can be completed cost‑efficiently across contiguous sections.

Presenters emphasized coordination with neighboring jurisdictions and the school district; the city reported the sanitation district had obtained permits where the line crosses into adjacent jurisdictions and will coordinate to minimize service interruptions during school holidays. The council thanked the district for the presentation; no formal action or vote on the project occurred during the meeting.

Next steps: the sanitation district and city staff will continue coordination on final permits, outreach materials and follow‑up on outstanding accessibility questions before construction begins.
