For technicians, architects, and engineers, a revised guide to estimating customer demand and maximum expected flow for sizing new service lines and meters. The manual (first published in 1975) presents a field method of demand profiling that can be used to evaluate actual customer use patterns and

This third edition of M22 contains information needed to estimate customer demand and maximum expected flow that can be used to size new service lines and meters. This edition expands the ways to approach the sizing of water service lines and meters and offers improved methods for the sizing of dedicated irrigation meters. M22 includes a useful field method called demand profiling that can be used to evaluate actual customer use patterns and help optimize meter size selection. The data presented in M22 were obtained from field measurements, utility surveys, technical publications, and hydraulic design calculations. This manual emphasizes that utilities having more information about a specific sizing situation will result in the best sizing decision from the tap to the meter. This information has been condensed into a simplified format to assist readers in addressing most common service conditions. The methods contained in this manual are appropriate for water utility managers, engineers, planners, technicians, field operations personnel, and consultants involved with designing and constructing projects requiring water service.

This utility operations manual will guide the utility in choosing the best sizes for customer water meters and service lines. Historically, water utilities sized customer service connections and meters based upon the peak flow rates that the meter was expected to encounter. Since peak flows occur only rarely, meters sized in this way record the lower, average daily flow in the low end of their design range

AWWA's most popular handbook for distribution operators, this handbook provides a complete introduction to water distribution system operation and equipment.

In this handbook readers will find industry-approved procedures for water utilities to conduct systemwide water audits to assess real and apparent distribution-system water losses, recover lost revenue, and detect and repair pipe leaks.
