Dell Rapids, SDEngineer: Banner & Associates Permitted Plant Flow: North Plant- 4.0 MGD Installation Date: 2004
The Minnehaha Community Water Corporation service area covers most of the county. The corporation’s well field and treatment plant are located above the Big Sioux aquifer midway between Dell Rapids and Baltic. The system serves over 3,000 individual rural users in addition to the cities of Baltic, Crooks, Dell Rapids, Hartford, Humboldt and Sherman.
The North Plant was retrofitted with a Tekkem Slaker approximately one year after successful operation of the Tekkem Slaker that was purchased as part of the construction of the New Minnihaha South Water Treatment Plant.
In addition to the Tekkem Slaker, RDP Technologies provided a Bin Activator for the existing lime storage silo followed by a new lime screw conveyor. The Tekkem Slaker then discharges lime slurry by gravity to an RDP Slurry Aging Tank that is located in lower floor of an adjacent building. The lime slurry passes over a stainless steel vibrating screen, provided by RDP, as part of the gravity path to the Slurry Aging tank.
