Northglenn Underground

The Northglenn Underground project will update and improve an aging wastewater infrastructure that brings much of the sewage from the city to the wastewater treatment plant in Weld County. The project includes critical repairs and replacement of components that are over 30 years old. 

  • To improve the capacity, efficiency and lifespan of the city's wastewater system. The repairs will also reduce corrosive gases, which reduces odors in the city and near the wastewater treatment plant.

  • New pumps in Lift Station A. These pumps collect and push the sewage to the wastewater plant.
  • New sewer Force Main pipes take sewage from Lift Station A to roughly 120th Avenue.
