SDCL § 9-48-28: Metering of water supply to determine sewer charges--Consideration of water consumed without return to sewer system.

The metering of private water supplies produced or operated on premises served by public sewer utilities may be required. If the use or consumption of water on any premises is taken into consideration in determining the charge to be made for the use of sewer utilities serving the premises, the municipality shall consider the amount or proportion of water used on the premises that does not reach or burden the sewer utilities.
