Project Overview:

In partnership with Garney Construction, Loveland Water and Power (LWP) will be working to expand the Wastewater Treatment Plant located at 920 Boise Ave. The long-awaited $32M expansion project will completed in four phases. Construction will begin in May 2017 and completed by September 2019.

Project Goals:

Wastewater Treatment Plant (WWTP) Expansion Project Goals:

  • Increased regulatory requirements - In accordance with new State permit limits, the plant effluent to the river must meet very low limits for phosphorus and nitrogen by 2020.
  • Increase capacity to meet population growth - When all work is complete, the WWTP will be re-rated from 10 million gallons per day (MGD) to 12 MGD allowing for an additional 10 to 15 years of growth for Loveland residents.
  • Replace aging infrastructure - Including renovation of the existing secondary clarifiers, improvements to the existing anaerobic digesters, and replacement of the headworks screening equipment.
