Section 110.501. Metering and measuring requirement

(a) Each public water supply agency shall measure its withdrawals and water transferred through interconnection with another public water supply agency by means of a continuous-recording device or flow meter, accurate to within 5% of actual flow.

(b) Each hydropower facility shall measure its withdrawal and instream hydropower use by means of a continuous-recording device or flow meter or shall calculate its withdrawal and use based upon electrical generation or turbine flow rates or other method, accurate to within 5% of actual flow.

(c) Each person whose total withdrawal from a point of withdrawal, or from multiple points of withdrawal operated as a system either concurrently or sequentially, within a watershed equals or exceeds an average rate of 50,000 gallons per day in any 30-day period and each person who obtains water through interconnection with another person in an amount that exceeds an average rate of 100,000 gallons per day in any 30-day period shall measure or calculate:

(1) Withdrawals, and water obtained through interconnection with another person by means of a continuous-recording device or flow meter or other method, accurate to within 5% of actual flow.

(2) Consumptive uses by a means or method accurate to within 10% of actual flow.

(d) Upon written request from a registrant, the Department may grant exceptions to the 5% or 10% performance standards, if maintenance of the standard is not technically feasible or economically practicable.

(e) A person who is subject to § 110.204(b) (relating to voluntary registration) or § 110.301 (relating to reporting requirement) but is not subject to subsections (a)—(c) shall measure or calculate the withdrawals or uses by a means or method, which is based upon established scientific principles, design or manufacturer’s product specifications, or research results.
