Sioux Falls Regional Water Reclamation Plant Expansion Project


In February of 2018, the City finalized a Facility Plan that defined major improvements to its regional water reclamation facililty (WRF) and collection system. These improvements will extend the useful life of the overall system and address growth and economic development for the City region over the next 20 years. This is the first major expansion project in over 40 years since the original facility was built.
