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 the reclassification of the receiving stream. Ammonia limits were lowered, and E. coli limits were added to the permit. Following completion of the construction project, the WWTF has achieved significant improvements in the quality of its effluent and is now able to meet the 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.

We designed WWTF improvements to implement the selected technology, a Submerged Underground Growth Reactor (SAGR) system. This project included the 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 installing composite influent and effluent samplers and coordinating with the city to begin meeting requirements for continuous discharge facilities.

Banner provided construction administration and observation services for this project.
