City of Maple Ridge Water Meter Material Specifications & Design Guidelines February 2015 Page 7 3. DESIGN AND INSTALLATION GUIDELINES 3.1 Meter Sizing For all existing single family
residential homes without fire sprinklers, the water meter size shall be 19mm diameter, unless the Applicant’s Engineer can demonstrate the need for a larger meter. In all other cases,
the meter shall be sized in accordance with AWWA Manual of Water Supply Practices M22 Sizing Water Service Lines and Meters taking into account specific requirements outlined in the
meter sizing calculation sheet included in Appendix A. To be clear, this sizing methodology is based on the AWWA fixture value method, and not the fixture unit method employed in the
BC Building Code for piping within buildings. The maximum operating range for a water meter shall not be greater than 90% of the maximum instantaneous flow capacity as outlined by the
manufacturer, with a maximum pressure loss of 48 kPa (7 psi) at the design flow rate. The meter size selection should not compromise the operating range or the long term life of the
meter and must ensure that pressures supplied to the property are appropriate for the intended use. In this same regard, the analysis should be sufficiently thorough to avoid unnecessarily
over-sizing the meter. In some instances, this may result in a smaller meter than the water service size. Table 2 is provided as a guide for various meter types and sizes for a range
of uses and flows. The values presented in this table are based on AWWA standards and do not necessarily reflect manufacturer data. Accordingly, the Applicant’s Engineer shall confirm
that the manufacturer’s performance data for the recommended meter size and type satisfies the design requirements for the given application. Table 2 – Meter Selection Guide Water Use
