Zone 4C Pump Station and Transmission Pipeline

Construction Update

April 2018

The exterior finishes of the pump station and majority of the finish grading and pavement installations are scheduled to take place throughout May. Installation of the internal plumbing, electrical and mechanical systems are nearing completion and testing of the equipment and systems is scheduled to begin in late May. Testing should take up to 10 weeks. Removal of the construction trailers and final site restoration will take place during the later stages of testing.

Installation of the transmission pipeline was completed in the summer of 2017, and all trails have been rebuilt and are open for public use. The disturbed areas have been seeded and will continue to be monitored until vegetation is established.

September 2017

Construction on the pump station and pipeline projects began in April of this year. Both projects were hampered by the rainy weather we experienced in April and May. However, as the weather has dried out significant progress has been made.

Excavation for the below ground pump room was completed in April, followed by the placement of the concrete foundation and pump room walls. This fall the remainder of the exterior walls of the pump station will be completed, allowing the roof to be installed and the structure dried-in to accommodate the installation of pumps and control equipment.  The pump station is on schedule to be complete and operational by the beginning of the 2018 irrigation season.

Construction of the 7,000 linear foot pipeline began with the installation of mainline connections in S. Broadway and Wildcat Reserve Parkway. Following the connections, the contractor began installing pipe from S. Broadway east, navigating through the open space and along the Marcy Gulch drainage. Pipe installation and testing was completed in early August.

Site restoration for the pipeline began in August with seeding along all the disturbed areas. Both soft surface and concrete trails were restored and reopened for full trail use by early September.  Minor items are being addressed throughout the month of September and the pipeline project is expected to be completed in October.

Frequently Asked Questions

Centennial Water will be constructing a new pump station and transmission pipeline. For more information about the project please review the frequently asked questions below. If you have questions or would like to provide feedback about the project, please send an email to info@highlandsranch.org.

  1. Why does Centennial Water need a new pump station?
  2. Where will the pump station be located?
  3. Where will the transmission pipeline be located?
  4. What is the project schedule?
  5. Will the project impact the use of open space trails?
  6. What will the project look like?

1. Why does Centennial Water need a new pump station?

The zone 4C pump station and transmission pipeline will boost delivery of potable water to pressure zones that serve more than 60 percent of customers within the Highlands Ranch service area. The project will allow Centennial Water to meet current day peak demands.

2. Where will the pump station be located?

The pump station will be located in the undeveloped area east of S. Broadway, north of Wildcat Reserve Pkwy. The location was defined by the existence of large transmission lines in Broadway and the hydraulic parameters set by storage reservoir elevations.

3. Where will the pipeline be located?

The transmission pipeline will connect to existing main lines in S. Broadway and Wildcat Reserve Pkwy. The pipeline will be aligned along the drainage corridor between the two streets, cross Gateway Dr. and parallel the northern right-of-way of Wildcat Reserve Pkwy.

4. What is the project schedule?

5. Will the project impact the use of open space trails?

Yes, trail closures will occur. Please refer to the trail closure map for a list of trail closures and alternate routes.

6. What will the project look like?

The project consists of two components, the pump station and the transmission pipeline.

The transmission pipeline will be a buried pipeline that conveys water to and from the pump station. Following installation of the pipeline via open trenching, the disturbed areas will be  restored to preconstruction conditions.

Centennial Water has worked diligently with the design team to use the topography and natural landscape of the area where the pump station will be located to minimize visual impacts once it is complete. A significant portion of the pump station will be buried; however, there will be an above ground structure required for operations and maintenance. The building footprint will be approximately 62 feet by 70 feet with a wrap around driveway. The architectural treatments on the building are a barn theme to reflect the ranching heritage of the area while also meeting functional needs. Once complete, the pump station will be operated remotely. There will not be daily staffing of the facility.
