North Huron Interceptor Sewer Replacement Project

NorthHuronSewerProjectMay2021The City of Westminster is investing $16 million in sewer improvements for current and future customers in the North Huron corridor of the city. This project is funded by the Westminster Economic Development Authority's North Huron Urban Renewal Authority and ratepayer funds are not being used.

Project Overview

New sewer pipe will be installed in W 136th Avenue, N Huron Street, Orchard Parkway, and 134th Avenue. Sewer mains in this area are aged, difficult to maintain, and are at their design capacity and need to be replaced.


Interceptor construction in 136th Avenue is now complete and traffic has been reinstated on the south half of the road.

Construction continues in Orchard Pkwy near the wastewater treatment facility and is progressing north to 136th Ave. This work phase is anticipated to be completed in November, 2021. Construction will then progress north of 136th Avenue along Orchard Parkway. beyond Lowes and this phase is anticipated to finish mid-January, 2022.

Interceptor construction will also begin early September at 134th Avenue and Huron Street. Due to heavy equipment operating in this area, 134th Avenue will be closed west of Huron Street until late-October, 2021.

This schedule is subject to change and will be updated as new information becomes available.


Businesses impacted by this work will be notified in advance and disruption to water and sewer service will be minimal. Expect traffic delays during construction and take alternate routes if possible.

The pedestrian trail segment south of Walmart connecting Huron Street to the pedestrian underpass at I-25 will be closed through at least January 2022. Portions of the trail have been removed and heavy equipment is operating in this construction area. Pedestrians are asked to stay clear of the trail closure and follow the posted detours.

The city's RV Dump Station at the Big Dry Creek Wastewater Treatment Facility will remain closed through October 2021. Updates for the reopening of the dump station will be provided at the RV Dump Station link as they become available.

Construction Notification

Customers and businesses impacted by water or sewer service will be notified in advance of the work. Commuter traffic will be notified of modifications to traffic flow with message boards, traffic control devices, website updates, and on the city's social media platforms.

The city strives to maintain a high level of service to our water and sewer customers. Thank you for your patience!
