WATER USE PERMIT INFORMATION MANUAL
PART B, BASIS OF REVIEW
Chapter
5.0 MONITORING REQUIREMENTS
The following provisions are added to the end of section 5.1. The paragraphs under the heading “Flow Meters” are primarily replicated from Chapter 6, the section titled “PUMPAGE REPORTING, 5. Flow Meters” except as noted through strikeout/underline. Paragraphs that are completely underlined are new:
Flow Meters
All required flow meters shall adhere to the following requirements and shall be installed and maintained as follows:
1. All meters shall be non-resettable, totalizing flow meters that have a totalizer of sufficient magnitude to retain total gallon data for a minimum of the three highest consecutive months permitted quantities. If other measuring devices or other alternative accounting methods are proposed, prior to installation, the Permittee shall submit documentation that the other measuring devices or accounting methods meet the accuracy requirement provided below stipulations listed in this condition. If the alternative accounting method involves a meter belonging to another entity or to an alternative water supply provider, the Permittee shall submit documentation from the owner/supplier that the meter readings conform to these meter requirements. Approval for other measuring devices or accounting methods must be obtained in writing from the Regulation Department Director.
a. The flow meter(s) or other approved flow-measuring device(s) shall have and maintain an accuracy within five percent of the actual flow as installed.
b. Accuracy testing requirements:
i. For newly metered withdrawal points, tThe flow meter installation-water piping system shall be designed for inline field access for meter accuracy testing.
ii. The meter shall be tested for accuracy on-site, as installed, every five years beginning from the date of its installation for new meters or from the date of initial issuance of the this permit condition containing the metering condition with an accuracy-test requirement for existing meters.
iii. The testing frequency will be decreased if the Permittee demonstrates to the satisfaction of the District that a longer period of time for testing is warranted.
iv. The test will be accepted by the District only if performed by a person certified on knowledgeable in the test equipment used as described in the section entitled Flow Meter Verification, below.
v. If the actual flow is found to be greater than 5% different from the measured flow, within 30 days the Permittee shall have the meter re-calibrated, repaired, or replaced, whichever is necessary. Documentation of the test and a certificate of re-calibration, if applicable, shall be submitted within 30 days of each test or re-calibration.
2. The meter shall be installed according to the manufacturer’s instructions for achieving accurate flow to the specifications above, or it shall be installed in a straight length of pipe where there is at least an upstream length equal to ten (10) times the outside pipe diameter and a downstream length equal to two (2) times the outside pipe diameter. Where there is not at least a length of ten diameters upstream available, flow straightening vanes shall be used in the upstream line. Existing systems that would require retrofitting to achieve the above standards will not be required to retrofit provided it is documented on the Meter Accuracy Verification Form, Form No. LEG-R.021.00 (07/08), incorporated herein by reference, that the flow meter is accurately and reliably measuring flow over different flow ranges or for the permanent operating flow. This form can be obtained from the District’s website (www.watermatters.org).
3. If a metered withdrawal point, AWS inflow line or re-pump withdrawal point is not utilized during a given month, the meter report shall be submitted to the District showing the same meter reading that was submitted the previous month.
4.3. Broken or malfunctioning meter:
a. If the meter or other flow-measuring device malfunctions or breaks, the Permittee shall:
a. Notify the District within 15 days of discovering the malfunction or breakage;
b. The meter must be rReplaced the broken or malfunctioning meter with a repaired or new meter, subject to the same specifications given above, within 30 days of the discovery; and
c. Submit estimates of their pumpage as described below.
c. If the meter is removed from the withdrawal point for any other reason, it shall be replaced with another meter having the same specifications given above, or the meter shall be reinstalled within 30 days of its removal from the withdrawal. In either event, the withdrawal point shall not lack a fully functioning meter shall not be off the withdrawal point for more than 60 consecutive days.
5. While the meter is not functioning correctly off the withdrawal, the Permittee shall document the total amount of time in minutes that the withdrawal point was used for each month and multiply those minutes times the pump capacity (in gallons per minute) for total gallons estimate their use by multiplying the number of hours the withdrawal point was used during that month times the flow capacity of the pump or mainline, whichever is appropriate, or the Permittee may request instructions on how to estimate use from the Permit Data Section. The estimate of the number of gallons used each month during that period shall be submitted on District scanning forms and noted as estimated per instructions on the form noted as an estimate when it is submitted to the District. The reason for the necessity to estimate pumpage shall be reported with the estimate.
6. In the event a new meter is installed to replace a broken meter, the meter it and its installation shall meet the specifications of this Chapter condition. The permittee shall notify the District of the replacement with the first submittal of meter readings from the new meter.

Flow Meter Verification
The following requirements pertain to the required flow meter testing:
1. The Flow Meter Accuracy Verification Form referenced above under the heading “Flow Meters” shall be completed and provided to the District for each flow meter tested. This form can be obtained from the District’s website (www.watermatters.org). If the test equipment provides a printout of data that was input, this shall be submitted with the worksheet. The equipment’s water temperature shall be set to 72 degrees for ground water, and for other water sources the measured water temperature shall be used.
2. Permittees shall demonstrate that the results of the meter testing are accurate. This demonstration may be met by submitting documentation with the Flow Meter Accuracy Verification Form referenced above under the heading “Flow Meters” that:
a. The manufacturer of the test equipment, or an entity approved or authorized by the manufacturer, has trained the operator to use the specific model test equipment used for testing; and,
b. Includes a date of calibration of the testing equipment within the previous twelve months, and the test lab's National Institute of Standards and Testing (N.I.S.T.) traceability reference number.
3. A diagram showing the precise location on the pipe where the testing equipment was mounted shall be supplied with the form. This diagram shall also show the pump, installed meter, the configuration (with all valves, tees, elbows, and any other possible flow disturbing devices) that exists between the pump and the test location clearly noted with measurements. If flow straightening vanes are utilized, their location(s) shall also be included in the diagram.
4. A picture(s) of the test location, including the pump, installed flow meter, and the measuring device, or for sites where the picture does not include all of the items listed above, a picture of the test site with a notation of distances to these items.
5. A minimum of two separate timed tests shall be performed for each meter. Each timed test shall consist of measuring flow using the test meter and the installed meter for a minimum of four minutes duration. If the two tests do not yield consistent results, additional tests shall be performed for a minimum of eight minutes or longer per test until consistent results are obtained. If the installed meter has a rate of flow, or large multiplier that does not allow for consistent results to be obtained with four- or eight-minute tests, the duration of the test shall be increased as necessary to obtain accurate and consistent results with respect to the type of flow meter installed. The results of two consistent tests shall be averaged, and the result will be considered the test result for the meter being tested. This result shall be expressed as a plus or minus percent (rounded to the nearest one-tenth percent) accuracy of the installed meter relative to the test meter. The percent accuracy indicates the deviation (if any), of the meter being tested from the test meter.
6. Flow meters that fail to meet the District’s accuracy requirements must be repaired or replaced within 30 days. These meters shall be retested after the repair and the results submitted to the District within 30 days of the test.
