Section R12-15-903. Approved Water Measuring Devices and Meth- ods

A.      Any measuring device is approved by the Director if it is installed, maintained, and used in accordance with the manu- facturer’s recommendations, and if it meets the accuracy requirements set forth in R12-15-905(A).

B.       An approved measuring device shall be used with an approved measuring method set forth in R12-15-903(C) or an alternative measuring method approved by the Director as provided in R12-15-909(A).

C.      The following water measuring methods are approved by the Director:

1.        Totalizing measuring method: This method requires an approved measuring device which continuously records the volume of water passing through the measured sys- tem;

2.        Electrical consumption measuring method: This method requires measurements of either pipeflow rates or open- channel flow rates used in combination with electrical energy records;

3.        Natural gas consumption measuring method: This method requires measurements of either pipe flow rates or open channel flow rates used in combination with nat- ural gas energy records;

4.        Hour meter measuring method: This method requires measurements of either pipe flow rates or open-channel flow rates used in combination with hour meter readings;

5.        Elapsed time of flow method: This method requires mea- surements of flow rates used in combination with elapsed time of the flow. This method may be used only by a responsible party who receives water from an open chan- nel or by a person or entity who delivers water in an open channel to one or more grandfathered rightholders or per- mit holders, if it is not possible to use the electrical or gas consumption measurement methods or hour meter mea- suring method.
