River View Sewer Express Line

Project Name: River View Sewer Express Line
Start Date: June 30, 2025
Project Duration: 3 months
Project location/address: River View Road and Porphyry Road, Gypsum, CO
Project Status: Project is in Phase II which includes trenching and installation of the improved sewer line along River View. Phase II of the project will take place at the intersection of River View and Hwy 6. Phase III is anticipated to begin by October. 

  • Phase II will move east from Porphyry & River View toward Hwy 6..
  • Crews will coordinate directly with homeowners as work approaches each property.
  • Homeowners may experience temporary driveway access restrictions during the project. On-street parking will be permitted when driveway access is blocked.
  • River View Road is closed within the project area but remains open to local and homeowner traffic only. Residents on River View outside the project area should follow the detour shown in the image below.
  • Expect large, deep trenches, rough surfaces, construction materials, equipment, and dust in the street until final paving is complete—it will be messy.
  • The estimated completion for this project is October.

Project Description: The Town will install a new 24-inch diameter sewer express line to divert most of the town's wastewater away from the existing neighborhood system in Eagle River Estates, directing it straight to the new Wastewater Treatment Plant. Due to the depth of the sewer line and the likelihood of encountering groundwater, the project will be complex.  Once the pipeline installation is complete, the roadway will be repaved with new asphalt over the excavation area. No additional street improvements are included in this project. Funding for this project comes in part from a Colorado Energy and Mineral Impact Assistance grant, with matching funds from the Town.

The project will add approximately 3,100 feet of new sewer line, enhancing the system’s resilience. Construction is expected to begin in mid-summer and will last about three months. Temporary traffic impacts will occur in the neighborhood, with single-lane traffic around the work area as it progresses along the street.
