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.
The revised manual contains new material reflective of isses and changes in this evolving water industry. The manual provides guidance and recommendations on choosing rate structures and setting water rates, fees, and charges which will cover utility costs and future needs. The manual covers all types of rate structures, such as block rates, uniform rates, conservation rates, surcharges, and many others.
This completely updated version discusses such topics as raw water quality, treatment options, treatment chemicals, and drinking water regulations. It includes detailed illustrations, photographs, supplemental reading lists, a glossary, and an index.
This manual provides a review of experience and design theory regarding steel pipe used for conveying water. This fourth edition of the manual was approved in March 2003, and includes a new discussion of chemistry, casting, and heat treatment, plus new discussion of stress evaluation in spiral-welded pipe. There is revised material on ring girder d
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
