Council authorizes $22,791 purchase of end‑seal equipment for sewer system
Summary
The council authorized the purchase of a Quick Lock end‑seal system and initial supplies for the city's wastewater collection system at a cost of $22,791.17, to help reduce inflow and infiltration where cured‑in‑place pipe meets manholes.
The Mexico City Council authorized staff to purchase a Quick Lock end‑seal system and initial sleeves for the wastewater collection system at a quoted cost of $22,791.17.
City staff described the equipment as a pneumatic device used to install end seals at the downstream end of lined pipes where they enter manholes. “These seals would allow us to go ahead and seal right at the manhole only, hence the name end seal, and allow us to begin mitigating that issue,” said Drew Wilford, a city staff presenter. Staff said the devices address water tracing into the collection system at creases or junctions where cured‑in‑place lining alone has not fully prevented infiltration.
Wilford said the initial purchase includes three device sizes to match common pipe diameters (8‑inch, 10‑inch and 12‑inch) plus starter supplies. Staff said replacement installation sleeves are purchased over time and estimated sleeve costs vary by size; staff characterized sleeve prices as a material cost to be bought as needed. The council moved, seconded and approved authorization for the purchase; roll call recorded affirmative votes.
The purchase is intended to be the start of a multi‑year installation program at lined‑pipe manholes; staff said they will return to place seals at sites identified from prior lining projects. The meeting record did not attach a written inventory schedule for future sleeve purchases or a total multi‑year budget for full installation.
