M E. Simpson Co , Inc I Large Water Meter Test and (Repair Program Page 2 Meters will be tested across a range of flows to determine patterns of mechanical wear at various flow rates. Flow rates used will be a combination of AWWA recommended flow rates (per M-6 manual of the AWWA) and meter manufacturer flow rates. Meters will be tested and calibrated to bring them within accepted accuracy limits. Some meters need to be removed from their setting(s) for "offsite" testing due to existing plumbing configurations. Efforts will be made to keep the service disruption to a minimum. ♦ If a water service loss for any period of time is intolerable to the water customer, recommendations will be made to the Utility to include a by-pass around the meter so service disruption will not occur during the testing. The equipment used will be described in the "Equipment to be Used" section. The Project Team will document all meter testing results and calibrations. Meters requiring extensive calibrations (not worth time and material) or obsolete meters, will be brought to the Meter Superintendent's attention for potential meter change -out by the Utility. The cost basis for recommending a meter change out(s) will be determined at the kick-off meeting and agreed upon between M.E. Simpson Co. Inc. and the Utility. All calibrations will be attempted to be performed the same day of testing. After calibration, the meter shall be tested to conform to test specifications outlined elsewhere in this Specification. In its daily report to the Water Department Manager, the Project Team will review the previous day's progress, and outline the meters to be tested that day. It may be necessary to conduct parts of the meter -testing program during "off hours" (i.e. nights). This may be required in a building(s) that has a high daily usage, but is closed at night. The Project Team will give 24-hour "notice of intent" to test meters that require after hours or nighttime work. This will allow the Water Utility to plan for area access, and give Police Department (and other Public Works Divisions) notification as to the planned testing activity. Calibration parts used will be NSF 61 certified. (All new meter parts available now currently meet this standard.) Care will be exercised when water is discharged during testing. Test meter water flow discharge will not be allowed to cause interference with private property, pedestrian or roadway traffic, and will have minimal environmental impact. ♦ Meterskpcated in r.onfinee , , L) nLgj� raH Lw testecl...uO .a cc, iieµd.,.�.:(J fin d ttu c�a:ttrr�tw (t � a,� rdlurli �; �ry�rFu ��G�anfG (.Iw��wwGs��i A the v�a��tcn-.rw��t�u"�r [gir tii^�tu��.
