Lift Station No. 28 Equalization Tank; Project No. 2022-S-3
Lift Station No. 28 Equalization Tank; Project No. 2022-S-3 is for the construction of a new sanitary sewer pump station and buffer tank that will extend the useful life of existing Lift Station No. 28 by effectively improving its peak capacity. Lift Station No. 28 is located northeast of the intersection of Husker Highway/James Road. Based on a 2021 update to the 2014 Wastewater Collection System Master Plan, the pipes directly upstream of Lift Station No. 28 will surcharge in peak capacity events in the near future. Several options were evaluated to solve this problem, with the most effective treatment being to install an extra pump station and a storage tank to essentially increase peak pump capacity by pumping the additional flow into a storage tank and discharging stored wastewater when downstream system capacity allows. Along with a new pump station and storage tank, a control system will be required to control operations.
