Kings Park Sewer Project, October 2013
Kings Park is a small community of 14 homes on the banks of the Zumbro River, near the confluence of the Zumbro’s Middle Fork and South Fork. Some of the homes were discharging sewage to the surface or directly into the Zumbro River without treatment and the rest had old sewer systems that were no longer compliant. Starting in 2011, the community began exploring options for a new sewer system with the strong support of Oronoco Township, which agreed to own and manage the new system for the community.
The lowest cost treatment system was to build a cluster (shared) mound for the drainfield and one of the community members agreed to sell land on which to locate the new system. Four homes have a grinder pump station and the remaining homes have step pumps to pump sewage through new collection lines to large septic tanks next to the mounds. The sewage is then pumped up to the mound and dispersed for treatment. The community received two grants from the Minnesota Public Facilities Authority, a state agency that assists communities to fund sewer infrastructure, for 80% of the project cost. Construction began in late August and will be completed in November.
