About North System Renewal The water we provide helps sustain a vibrant city

Denver Water’s North System brings snowmelt from the mountains through reservoirs, pipelines and a treatment plant to produce clean, great-tasting drinking water. It was constructed in the 1930s when most of the surrounding area was rural farmland. Now, 80 years later, the North System is reaching the end of its lifespan, and the pipelines and valves need to be replaced. In addition, a new treatment plant with advanced treatment technology is being built near Ralston Reservoir, while the existing Moffat Treatment Plant will be redeveloped and will serve primarily as a distribution site. The water we provide to 1.5 million people helps sustain a vibrant city and many of Denver’s surrounding suburbs. We are passionate and dedicated to the people we serve and those who live and work near our facilities.

These improvements will:

  • Provide a water system that will be more resilient to the effects of climate change and more adaptable to changing demands now and into the future.
  • Maintain the reliable delivery of safe drinking water.
  • Proactively prevent service failures by replacing a key part of Denver Water’s infrastructure that has reached the end of its useful life.

Project Elements

Northwater Treatment Plant

We are building a new, state-of-the-art water treatment plant next to Ralston Reservoir, north of Golden in Jefferson County. The Northwater Treatment Plant will be capable of treating up to 75 million gallons of water a day and will be equipped with disinfection technology that will provide more flexibility to respond to changes in water quality.

Moffat Treatment Plant

This facility will continue to treat water at a reduced capacity. Water treated at the Northwater Treatment Plant also will be sent to the Moffat facility, via the Northwater Pipeline, where it will be stored and distributed to customers.

Northwater Pipeline

We are installing a 66-inch-diameter pipeline, replacing one of the two existing pipelines, running 8.5 miles between Ralston Reservoir and the Moffat Treatment Plant. The new pipeline will transport treated water from the new Northwater Treatment Plant to the Moffat facility for distribution to customers.

Construction Activities

The work involves a traditional method of pipeline construction by performing an open-cut pipe installation. It consists of digging down to and exposing the existing pipe, removing the existing pipe or a section of it, installing a new pipe or a section of new pipe, and then backfilling the trench by placing dirt back in the hole to bury the pipeline. In preparation for the pipeline installation the contractor will saw cut the pavement in certain areas.

As part of our Good Neighbor Commitment, Denver Water is committed to maintaining safe work sites and mitigating noise, dust, traffic and other construction impacts on our neighbors. We aim to reduce delays and inconvenience by communicating well in advance before, during and after construction. During construction, residents may experience:

Noise and dust

Vibration and monitoring

Equipment, materials and construction crews located along the road and in the existing right-of-way

Temporary, intermittent lane and road closures.
Detours will be provided prior to closures

Property impacts
More information below

Access to homes and businesses will be maintained during construction. Residents and businesses will continue to have access to mail and package delivery, emergency services and trash pick-up. There may be instances when contractors need to temporarily close an intersection or driveway access. Denver Water staff will coordinate access with residents and businesses in advance of these closures, and crews will post detours to direct traffic.
If you are an affected property owner, you will be contacted directly by a project staff member.

Hours of Operation

Construction will generally occur Monday through Saturday, between 7 a.m. and 7 p.m. Crew schedules may vary on a day-to-day basis. Traffic control measures and flaggers will be in place to guide motorists around the work zone.

Crews will be working during daylight hours with potential for some work to occur after dusk. The project team does not expect nighttime or weekend work, but there may be exceptions in the event of emergencies, prolonged weather delays, COVID-19-related shutdowns or other unforeseen changes to the schedule.

Safety

Remember to drive through the area with caution and keep an eye out for construction crews and equipment.

Given the current public health situation, Denver Water is asking the public to maintain a safe social distance of 6 feet while work crews are upgrading the water infrastructure, ensuring safety for all. Together, we can make a difference and help limit the spread of the Coronavirus. Lean more about Denver Water's Coronavirus safety measures.

Frequently Asked Questions

To report property damage and/or bodily injury resulting from an incident involving Denver Water, please call our Customer Care line at 303-893-2444, Monday through Friday between 7:30 a.m. and 5:30 p.m.

This portion of Denver Water’s North System Renewal Project replaces the existing water pipeline that connects Ralston Reservoir to Moffat Treatment Plant, which is nearing the end of its useful life. If left in service, the existing pipeline would have an increasing risk of failing, which could cause significant damage to property owners. Denver Water routinely replaces pipelines and other infrastructure to ensure water gets delivered safely across the community.

We began outreach to neighbors in late 2020. We will continue to notify impacted residents in advance of work in their area and will provide any traffic or time sensitive construction updates in a timely manner.

Denver Water and its contractors follow local ordinances related to noise, dust and vibration. Local ordinances limit construction noise to between 7 a.m. and 7 p.m. (though this does not include crews arriving and leaving the site at the start and end of the workday). In the event the contractor cannot position a generator in a location that minimizes excess noise, the contractor will provide sound barriers such as hay bales or plywood. Crews will mitigate dust daily using water trucks. Vibrations will be monitored using seismic monitoring devices. The contractor will proactively communicate with homeowners about what to expect and promptly respond to concerns as they arise.

The contractor will work on two irrigation ditch crossings to install a pipeline casing: Agriculture Ditch, located between Bent Haven Drive and Linda Vista Drive and Rocky Mountain Ditch, located between Simms Drive and Applewood Knolls Drive. Once the ditch crossings are complete, the contractor will mobilize behind the Applewood Shopping Center King Soopers near the intersection of 32nd Avenue and Youngfield Street, and then work eastward toward Moffat Treatment Plant.

The construction crews anticipate completing, on average, 50-100 feet of pipeline construction per day. Please note, as with all construction, timelines are dependent on weather and other unforeseen circumstances. Construction will cross the Agricultural Ditch, located between Bent Haven Drive and Linda Vista Drive and Rocky Mountain Ditch located between Simms Drive and Applewood Knolls Drive. These crossings will take approximately two weeks to complete.

Yes, the contractor will fence any open trench at the end of each workday.

Construction materials will be stored at the contractor’s yard, but equipment and spoil piles (excavated dirt and rock) may remain on the street overnight.

Yes, the contractor will ensure trenches are safely covered at the end of each workday.

Due to the damage trees may cause to underground pipelines and restrictions they pose to construction or emergency access, Denver Water’s easement does not allow trees within easement boundaries. Any trees within the easement will be removed if they are in the direct path of construction. Denver Water and its contractor will attempt, but cannot guarantee, preservation of trees outside of the direct path of construction. Trees removed from within the easement will not be replaced. NOTE: Any trees within the easement that are not removed as part of this project are subject to removal at any time by Denver Water or its designated contractor to accommodate construction or future maintenance of the infrastructure.

We will make every attempt to save trees outside of Denver Water’s easement. In rare instances, construction within the easement may damage and/or necessitate the removal of trees outside of the easement. Denver Water will replace any trees outside of the easement that have been damaged or removed because of construction.

Yes, there will be instances where water and sewer services will be temporarily impacted. The contractor and project staff will communicate and coordinate with each property owner ahead of the scheduled date of service interruption.

The old pipeline will be removed in some sections and filled in and abandoned in other places. The pipe will be recycled or salvaged when possible.

All sidewalks and landscaping impacted by the project will be restored back to pre-construction condition. Although we aim to ensure restoration is complete one to two months after the final pipe installation is completed, restoration timelines depend heavily on weather conditions. If your property is directly impacted by construction, project staff will be in touch to provide specific details. You can read more about property restoration and street restoration on Denver Water’s website.

Denver Water coordinates with local governments and other agencies to minimize conflicts. In some cases, two unrelated projects may happen at the same time in an area to provide the least overall impact to residents.

This project is budgeted through Denver Water’s capital plan, which is built into current rates and funding mechanisms. The majority of landowners along the new pipeline are not Denver Water customers and will not incur any costs related to the project.
