Credit River Township is nestled in the rolling hills of southeast Scott County, Minnesota. Much of this region is covered with beautiful farmland and natural forests, however, the close proximity to both Minneapolis and St. Paul make it a haven for real estate developers looking to provide homeowners a neighborhood feel with a rural flavor. In the early 2000’s Credit River decided to grow their Township by promoting community wastewater treatment systems.
Natural Systems Utilities (NSU) was retained to help guide the Township into developing a comprehensive decentralized wastewater management plan, including ordinances, rate setting, planning budgets for capital replacement, as well as coordination with developers and builders.
Four housing developments were constructed in Credit River Township with the capacity for more than 200 total homes, each with their own septic tank effluent pumping (STEP) system that delivers wastewater to seven different community wastewater treatment systems. The seven systems are comprised of recirculating gravel and textile filter pretreatment systems, with final disposal to a vast network of pressure dosed mound systems. In all, the systems are designed to treat an average flow of more than 110,000 gallons per day.
