North System Renewal

Improving the safety and reliability of our aging system

Denver Water is upgrading and modernizing the northern portion of our water system. We are building a new water treatment plant, installing a new pipeline and redeveloping our Moffat Treatment Plant site. When finished, the system will be more resilient and adaptable to changing demands for water now and into the future.

Why it's important

Denver Water’s North System was constructed in the 1930s, when the surrounding area was mostly farmland. Now, 80 years later, the North System is reaching the end of its lifespan.

The North System’s pipelines and valves need to be replaced. The new treatment plant will feature updated technology, and the existing Moffat Treatment Plant will be repurposed into a distribution site.

Project components

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 react to changes in water quality.

Northwater Pipeline

We are installing a 5.5-foot diameter pipeline along an 8.5-mile route from Ralston Reservoir to the Moffat site in Lakewood, replacing one smaller existing pipeline. The new pipeline will transport treated water from the newly built Northwater Treatment Plant to the Moffat site for distribution to our customers.

Moffat Treatment Plant

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

How it affects our customers

These improvements will help maintain reliable, safe drinking water and avoid service failures that could adversely impact neighbors.

Being a good neighbor: Denver Water is committed to maintaining safe worksites and mitigating noise, dust, traffic and other construction impacts on our neighbors. We aim to reduce delays and inconvenience and communicate well in advance so commuters, residents and neighbors can plan accordingly.
