The District needs accurate water use data from permittees to fulfill its statutory responsibilities and to protect the state’s water resource. This information is crucial in determining permit compliance, calculating conservation credits, estimating water use and for use in water supply planning. District rules require that flow meters required by Water Use Permits be tested for accuracy every 5 years. Currently permittees have their flow meters tested and submit the information in many different formats. To ensure that the testing is properly performed so that the flow meters are accurately tested, staff has developed standardized accuracy requirements and a standardized test form. The proposed rule amendments incorporate the new flow meter accuracy test requirements. In addition, staff has moved some rule language from one section of the rules to another to consolidate related requirements and to clarify the process.
