Project Overview:

The existing 24” Boyd sanitary sewer interceptor (pipe) drains the largest sanitary sewer basin in the City of Loveland. Approximately 25% of the sanitary sewer from the City is collected and conveyed to the Wastewater Treatment Plant (WWTP) through the existing series of pipes. Given the growth of the City in the last 20 years sewer flows have increased substantially. As a result, the amount of remaining capacity in the existing wastewater lines has diminished. The wastewater master plan and associated wastewater hydraulic modeling has shown the need for a new parallel 24” pipe to convey future wastewater flows and current peak flows. 

Loveland Water and Power has worked with its engineering consultant, HDR, to design a parallel 24” PVC sanitary sewer interceptor to relieve the pressure on the existing pipe and to be able convey flows associated with future growth. The new sewer line will be approximately 6,800 feet. Construction will begin at the NE intersection of Highway 34 and Cheyenne Ave. The pipe route makes its way through Cheyenne Ave., E. 17th St., N. Boise Ave., Silver Leaf Drive, and terminates in N. Madison Ave. approximately 650’ north of Silver Leaf Drive. 

As the design of the sanitary sewer transpired, other City Departments joined the project with infrastructure improvements that were previously planned for the same area. In addition, Loveland Water and Power will be installing a new 3,800 feet electric duct bank. The new duct bank will replace aging infrastructure and provide improved reliability. Likewise Public Work's Stormwater Department plans to drain accumulated stormwater from the intersection of N. Boise Ave. and E. 17th Street. This project, with inlets at the intersection, will convey stormwater, through a 36” pipe, to the Greeley Loveland Irrigation Canal, near the starting location of the sewer project. In addition to the sewer, electric, and stormwater improvements Public Works has decided to replace the aging curb, gutter and sidewalk along the project route. Our hope is to be able to combine these infrastructure needs into one project to realize cost savings and inconvenience.

 

Project Goals:

The goals of the Parallel Boyd Sanitary Sewer Improvements and Associated Utility Improvements are to:

  • Replace aging infrastructure
  • Planning for future growth
  • Increase reliability and operational flexibility in Wastewater systems
  • Relocate equipment that is difficult to access
  • Alleviate pressure on existing facilities
  • Replace failing and cracked concrete and improve sidewalk condition
  • Improve localized drainage and reduce potential for flooding 
  • Additional looping of infrastructure to increase restoration times
