Kingbrook Rural Water System, Inc.

Kingbrook Rural Water System, Inc. is a not-for-profit corporate entity registered in the System for Award Management (SAM) since April 2010, located in Arlington, South Dakota. The organization specializes in rural water infrastructure development and service provision, focusing on water system improvements and distribution network enhancements for rural communities in South Dakota. As a tax-exempt organization, Kingbrook Rural Water System has established itself as a critical infrastructure support entity that works closely with state-level agricultural and environmental departments to improve water access and quality for rural residents.

Through federal grant sub-awards, Kingbrook Rural Water System has consistently demonstrated expertise in comprehensive water infrastructure projects. In November 2020, the organization received a grant from the Department of Environment and Natural Resources to replace the water distribution system in Oldham, including installing new PVC water lines, meter pits, service lines, and recoating the existing water tower. More recently, in July 2025, the organization was awarded two identical sub-grants from the South Dakota Department of Agriculture and Natural Resources to construct significant transmission main infrastructure. These projects involved constructing 8 miles of 12-inch and 7.5 miles of 10-inch transmission mains, with the goal of enhancing water system reliability and expanding capacity at the DeSmet Water Treatment Plant service area. The sub-grants demonstrate Kingbrook Rural Water System's ongoing commitment to improving rural water infrastructure through strategic pipeline and facility development.
