Municipal Reservoir #1 acts as the final line of natural filtration for settling and sedimentation before the raw water reaches the R.B. Simms Drinking Water Treatment Facility. This natural environment and protected buffer on Spartanburg Water System property up to the 780’ Mean Sea Level Contour Line around the reservoir helps Spartanburg Water System continue to fulfill our mission of delivering quality water in a reliable manner. Preventing runoff pollution means less chemicals are used in the drinking water treatment process. This is important both for the customers we serve and the economic vitality of the region.
