M E. Sirripson Co,, Inc ( Large Water IMeter "Pest and Repair Program 11�e i3 Large Water Meter Evaluation, Testing and Repair Commercial/Industrial Water Meters Approach M.E. Simpson Co., Inc.'s commercial/industrial water meter testing and calibration services will provide the City of South Bend Water Works with the following benefits: ♦ Conserve freshwater resources • Substantially reduce the loss of revenue through improper/incorrect metering ♦ Make an immediate recover of lost revenue by calibrating any meters not functioning correctly ♦ Help in monitoring potential system operation and maintenance problems by inspecting water meter settings and potential backflow issues ♦ Promote proper accounting and financial reporting (GASB 34) ♦ Reduce the risk of water shortage and customer hardship (drought management) ♦ Ensure a sound and reliable water service for Water Utility customers Project Field Approach — Large Meter Testing M.E. Simpson Co. Inc. adheres to a strict method of field testing while taking into consideration the AWWA meter performance standards. This methodology allows for a systematic diagnosis of the meter's performance based on several flow rates across that specific meter's size and type beyond the AWWA's three tests (minimum, intermediate, and maximum). The testing will be done by comparative methods using a certified test meter to test the water customer's meter within its normal operating range or by volumetric methods per AWWA M-6 Manual. Our comparative test meters are Sensus (formerly Rockwell) that record total volume and current velocity for each of the 4 to 6 tests conducted. The test meters have "Electronic Registers" that are automatically reset to zero after each test. These comparative test meter units are themselves "Tested and Certified Accurate" at least once each year. Certificates of Accuracy are included aLg part of this proposal submission. Meter testing will be performed "on site" at the meter setting. The meter will be analyzed (as to the meter setting) to determine if the meter can be tested in place without removal, and without undue inconvenience to the water customer. (Large meters are tested in place to avoid removing them from their setting, thus possibly causing other problems.) Additionally, the meter setting can affect the accuracy of the meter if it is improperly configured. An inlet and outlet valve are necessary to isolate the meter from use during testing, and a correctly sized and positioned test port is needed to attain enough velocity of flow to test that meter across the range of flow rates. If a by-pass line is available, that will be flushed (by bleed valve if one can be used) prior to using, to insure no water service interruption for critical customers (such as hospitals). Proper meter application and sizing during testing will be assure that the correct meter is in place, and the setting is correct for the application. Meter accessibility is a major concern, especially in regards to potential revenue loss for large commercial accounts.
