Utilities warn of temporary pressure dips during pipeline tie‑ins; long‑term fix tied to new 36‑inch main
Summary
Utilities staff described ongoing pipe‑bursting work to replace decades‑old water lines, announced more complete paving on later phases, and said some neighborhoods have experienced temporary low pressure during valve and PRV work but that completion of a new 36‑inch main (anticipated autumn) should relieve persistent issues.
City utilities staff updated the council on a multi‑phase pipe‑bursting program intended to replace tens of thousands of linear feet of aging water main, and explained tradeoffs between limited patch repairs and full-width street paving. Staff said phase 1 replaced roughly 42,000 linear feet and is about 97% complete; phase 2 will replace a similar amount and will include greater pavement restoration. One project example (Ireland Street) required additional pavement work that increased local change‑order costs.
Staff also explained temporary low‑pressure events tied to pressure‑reducing valve (PRV) malfunctions and tie‑ins during construction. The distribution superintendent reported that after adjustments, previously low zones were holding at much higher pressures (for example, Winfield maintained around 73 PSI after fixes). Utilities said a full resolution awaits connection of a new 36‑inch main that will be tied in when demand drops (likely autumn) because the tie‑in requires extended temporary outages in affected zones.
Speakers: Utilities engineering and distribution staff (Enrique/Huenkemeyer/Mayo); multiple council members requested clearer pavement and restoration standards.
