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 rate payer funds are not being used. 

Project Overview

New sewer pipe will be installed from the city's wastewater treatment plant at W 132nd Avenue and Huron Street north to 136th Avenue. Sewer mains in this area are aged, difficult to maintain, and are at their design capacity and need to be replaced.


Fall 2020: Work began near the St. Anthony North Health campus and will transition to the city's wastewater treatment facility. No traffic impacts are expected during this initial phase of construction except for the closure of the city's RV Dump Station at the treatment facility.

Starting in December 2020, construction crews will begin installing sewer pipe from the wastewater treatment facility north along Orchard Parkway to 136th Avenue. 

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 detailed 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 November 30 through March 1, 2021. Closure of the trail is required due to heavy equipment operating in the construction area and portions of the trail will be removed. Pedestrians are asked to stay clear of the work area for safety purposes.

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!
