Big construction project knocking on the door

Pipeline replacement in Jefferson County will upgrade critical drinking water infrastructure from the 1930s.

June 18, 2018 | By: TAP Staff

Anticipating the arrival of large trucks and excavators to dig up your backyard is like looking forward to having a root canal. It’s not something people enjoy, but it’s important work that must get done.

Residents in several Jefferson County neighborhoods — who can expect to see construction work in their yards and neighborhood streets through 2020 as Denver Water replaces a critical water pipeline — may be feeling similar apprehension.

Enter Denver Water’s community relations team, whose goal is to make these types of disruptive projects as painless as possible.

Denver Water crews installed the original pipeline in the 1930s.

“This project is a challenge because this community has grown up around our infrastructure,” said Katie Knoll, community relations manager at Denver Water. “We are working with more than 150 commercial and residential property owners who are going to be directly impacted by this project.”

Denver Water has an 80-foot easement that runs the entire length of the pipeline corridor from Ralston Reservoir north of Golden to the Moffat Treatment Plant in Lakewood. The easement provides Denver Water with the right to access and work on private property to maintain and upgrade the pipeline that was build in the 1930s.

The work involves digging trenches that are 13 feet wide and 13 feet deep to remove the old 42-inch pipe and replace it with a new 66-inch waterline  that includes 84-inch diameter tunnel sections.

Once construction is complete, restoration crews come out to repair landscapes that were impacted by construction.

Residents can expect to see trench work across Long Lake Regional Park in Arvada in November. Construction in the neighborhood south of the Applewood Shopping Center will begin in Fall 2018 and move southeast into Lakewood in 2019. There will be minimal impact on the shopping center, but shoppers can expect to see some detours in the parking lots.

Homeowners can expect to see large construction equipment along the pipeline corridor during the project.

“We understand this work will be an inconvenience to residents,” Knoll said. “Our goal is to make sure we’re letting the community know when work is scheduled and what to expect.”

In addition to the in-person communications with impacted homeowners, Denver Water alerts residents about upcoming impacts by attending community meetings and events, distributing fliers and going door-to-door.

Real-time construction updates will be posted on denverwater.org where residents are encouraged to sign up for a newsletter for project updates.

Signs are also posted on neighborhood streets to alert drivers when traffic will be impacted.

The work is part of the North System Renewal — a larger renovation project to update the infrastructure that delivers 20 percent of Denver Water’s supply to customers in the metro area. The pipeline installation is expected to be completed by 2020, but the new pipeline won’t go into service until the new Northwater Treatment Plant is operational in 2024.

  1. As one of the homeowners on the NE side of Mountain Shadows Dr., I am concerned about the construction that will tear up our street and our established landscaping. We have presented our concerns in the past, but to no avail. As the project grows closer to our street, I hope you will reconsider the location of the new pipeline, especially when Mountain Shadows Drive is extremely wide and has adequate room for additional pipes within the street. I would like to know the difference in cost for moving the pipeline’s plannned placement vs. the cost of redoing the homeowners’ landscaping. I know my 50+ year old crabapple trees can not be replaced with other trees because they are in the 35′ zone. I hope you will reconsider the damage the project will cause our yards. Thank you.

    1. HI Ilene, thanks for your question.

      We understand your concerns. Denver Water takes many factors into account when planning large projects, including the installation of the new Northwater Pipeline to upgrade infrastructure that’s been in the ground since the 1930s. Recognizing that a lot has changed since the pipe was originally installed, we do try to limit impacts to communities around our projects when possible. We also have right of way specialists who have been and will be working with homeowners who are directly affected by this project.
