Beresford Wastewater Treatment Facility Improvements

Location
Beresford, SD

Banner completed a facility plan for the City of Beresford collection system and WWTF. In this facility plan, it was shown that Beresford’s wastewater discharge permit was becoming more stringent due to reclassification of the receiving stream. Ammonia limits were being lowered and E.coli limits added to the permit.

Following the completion of the construction project, the WWTF had significant improvements in quality of WWTF effluent and is now able to meet proposed future limits. The WWTF is now able to operate as a continuously discharging WWTF as opposed to intermittent discharge. This change allowed the WWTF to better treat the volume of influent wastewater and come into compliance under DANR regulations.

Project Details

Banner evaluated multiple methodologies of post-lagoon ammonia and e. coli reduction and worked with the city to select a technology. Banner also worked with the city to project anticipated wastewater flows for the next 20+ years and Banner worked with DANR to plan for potential future WWTF effluent limits.

Project Elements Provided

Banner designed WWTF improvements to implement the selected technology, a Submerged Underground Growth Reactor (SAGR) system. This project included design of a precast concrete blower building, site improvements for installation and maintenance of the SAGR cells, hydraulic and conveyance improvements, and integration improvements. The project also included the installation of composite influent and effluent samplers and coordination for the city to start meeting requirements for continuous discharge facilities.

Banner provided construction administration and observation services for this project.
