Wachter Avenue Lift Station and Forcemain Improvements

Project Summary:

Project Type:
Electrical Solutions

Owner:
City of Bismarck, ND

Overview:

The Wachter Avenue Master Lift Station was constructed in 1974. By 2012, it conveyed approximately 40% of the city’s wastewater flow. The lift station did not have adequate capacity to convey peak flows anymore and both the lift station and forcemain had age-related condition issues. In January of 2012, a major failure occurred in the ductile iron forcemain resulting in the diversion of wastewater to a storm drainage ditch. This resulted in requests to residents in South Bismarck to limit water usage.

In April of 2012, Apex Engineering Group was retained by the city to conduct a thorough assessment of the long-term viability of this critical lift station and forcemain. After studying several alternatives, Apex designed a new parallel forcemain to provide redundancy and lift station improvements to increase its capacity and reliability. The new forcemain was put into service in October of 2013 and the lift station upgrades were constructed in 2017.

Project Details:

The Wachter Avenue Master Lift Station and Forcemain project included a complete lift station rehabilitation The projects also included the following elements:

  • New electrical service.
  • Two emergency generators connected in parallel, installed in a common enclosure.
  • Four (4) 280 hp dry-pit submersible pumps.
  • The system is designed to allow for one generator to be out of service for maintenance and the other generator will run two of the four pumps.
