North Huron Interceptor Sewer Replacement Project

The 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 Pkwy, and 134th Avenue. Sewer mains in this area are aged, difficult to maintain, and are at their design capacity and need to be replaced.


Fall 2020: Sewer main replacement was completed near the St. Anthony North Health campus and transitioned to the city's wastewater treatment facility.

January 2021: crews began construction of the interceptor sewer in Orchard Pkwy near the wastewater treatment facility and work is currently progressing north to West 136th Ave.

In February boring operations began at the intersection of West 136th Ave and Orchard Pkwy and will continue through March. Lanes will be reduced with traffic control during this period. 

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


Businesses impacted by this work will be notified in advance and disruption to water and sewer service will be minimal. Expect delays during construction and take alternate routes if possible. More information about traffic impacts will be provided before each phase of construction begins.

The pedestrian trail segment south of Walmart connecting Huron Street to the pedestrian underpass at I-25 will be closed starting in November and extending through July 2021. 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 detours posted along the trail.

The city's RV Dump Station at the wastewater treatment facility will remain closed through June 2021. Updates for the reopening of the dump station will be provided when they are available.

Construction Notification

Customers directly impacted by this work will be notified in advance of the construction. Commuter traffic will be notified of modifications to traffic flow with message boards, traffic control devices, and updates 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!
