DENVER — May 14, 2021 — Denver Water is upgrading and modernizing the northern portion of its water system. This includes building a new, state-of-the-art water treatment plant, the Northwater Plant, next to Ralston Reservoir, north of Golden in Jefferson County.
A major milestone in the project took place Friday morning, May 14, when the concrete was placed for the first of two underground storage tanks. These clearwells will eventually store treated water from the plant before it is released into our distribution system. Here are some facts about the concrete placement:
- The tank is approximately 23 feet tall but will be buried mostly underground.
- The diameter is over 300 feet, greater than one football field in length.
- The slab pour comprises 1,400 cubic yards of concrete.
- 100 workers were dedicated to this portion of the project for the morning.
- 145 concrete trucks delivered concrete for the pour, approximately one every four minutes.
When the project is completed in 2024, the Northwater Treatment Plant will be capable of treating up to 75 million gallons of water a day. It will also provide the following benefits:
- Sustainability: Hydropower facilities on site will produce enough energy to operate the plant, significantly reducing carbon dioxide emissions.
- Reliability: Advanced treatment processes will improve resiliency in times of challenging treatment, such as during drought or wildfires.
- Flexibility: Modern and scalable facility design allows for adaptation to meet future water demands and changing regulatory standards.
