North Area Force Main

News & Updates...............

Zuni between 149th and 152nd Avenue has been closed due to a trench failure of the North Area Force Main and is expected to be closed through 5/21 depending on weather conditions.

Trench settlement was noticed in the area recently.  The contractor began work to correct the settlement and it was determined the trench was failing due to supersaturated (wet) conditions after the recent weather.   A geotechnical engineer will be evaluating the area on Monday to determine the recommended solution, weather pending.  

A detour has been put in place and the roadway closed for safety.  This is the same detour that was established during construction.  We ask all motorists, cyclists and pedestrians to adhere to the closure and follow the detour for safety.   

The contractor will be working as quickly as possible to repair and reopen the roadway.

Of the 7 ½ mile pipeline, all of the pipeline has been installed and the paving completed.  

Testing of the entire alignment has been postponed due to private development work impacting the force main at 160th and Huron.  Broomfield is working with the contractor to reschedule.

Background Information

The area of Broomfield north of West 160th Avenue, excluding the Anthem Development, has limited sanitary sewer infrastructure. The NALS was constructed and placed into service in October 2013. The NALS serves the Highlands, Palisade, Northlands, 275, and North Park developments. Currently, the NALS pumps wastewater to the Anthem Lift Station located along Highway 7 east of Lowell Boulevard. The NALS can only pump to the Anthem Lift Station until the Anthem Lift Station and dual force mains reach between 60 and 70 percent capacity. The construction contract was approved by Council at the October 22, 2019, meeting.

The North Area Force Mains (NAFM) project will construct a force main from the NALS directly to the Wastewater Treatment Facility located at 124th and Lowell Boulevard.  The force main will be over 7 ½ miles when completed.  

The contract was approved by Council at the October 22, 2019 meeting and construction was able to begin in late January when materials arrived.
