Rule 199-21.18 - Standards of quality of storm water drainage service

(1)Design and maintenance. Systems for storm water drainage by piped collection shall be designed and maintained in conformance with good engineering practices.

(3)Connections. Utilities providing piped storm water drainage shall control the installation and maintenance of the piped connection up to and including all storm water intakes. Connections shall be adequate to receive all storm water drainage from properties upgradient of the storm water drainage connection unless other upgradient connections are provided. Connections shall be pursuant to tariffs approved by the commission.

(4)Rates. Rates for storm water drainage service provided by a utility may be based upon the acreage drained, or by some other method pursuant to tariffs approved by the commission.

(5)Separate class. Storm water drainage service shall be considered a separate class of service for ratemaking purposes.
