The City of Watertown Parks, Recreation and Forestry Department operates and maintains the Cattail Crossing Golf Course. Irrigation water for the course is drawn out of nearby Lake Kampeska. The original intake screen located near shore allowed significant sediment into the system causing numerous maintenance issues and was not deep enough to use during low lake level periods. Banner evaluated several alternatives before recommending a new intake pipe design 1500 lineal feet out into the lake with a low-profile screen to meet SD GF&P watercraft clearance requirements. The new 20-inch diameter fusible PVC intake pipe is tied into the existing pump station, and weighted due to its shallow bury. It is designed to handle up to 2.8 feet of thermal expansion movement due to water temperature fluctuations. As Lake Kampeska is a fishery habitat, the screen was designed for low maximum allowable velocities to avoid trapping fish against the screen.
