M33 provides information about the most common flowmeters used in water treatment and custody-transfer applications, including the Venturi, modified Venturi, orifice plate, electromagnetic, turbine and propeller, transit-time ultrasonic, vortex, averaging Pitot, and averaging insertable electromagnetic. The discussion of these meters covers basic theory, installation and maintenance. General concepts applicable to flowmeters are also covered, including flow characteristics, performance issues, communication, information and signal outputs, and flowmeter selection.

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.

Annotation A guide to selecting, installing, testing, and maintaining water meters. Coverage includes selecting meter types, impacts on service adequacy, meter installation, testing of meters, and maintenance and repair of displacement meters. Also discusses shop layout and equipment, records, and remote registration. Includes a list of AWWA manuals. This manual discusses recommended practices; it is not an AWWA standard calling for compliance with certain specifications. Can be used by new and existing utilities of all sizes, and by design engineers and consultants. Member price $40.00. Annotation copyrighted by Book News, Inc., Portland, OR.

The manual identifies most of the problem organisms found in water supplies and provides recommendations for removing or inactivating them. Chapters describe and illustrate each organism, explain the types of problems it can cause, and offers suggestions for treatment or control. Nonpathogenic organisms covered include actinomycetes, iron bacteria, sulfur bacteria, nitrifying bacteria, nematodes, bloodworms or midges, crustacea, rotifers, zebra mussels, algae, and protozoa.

This manual provides operators, engineers, and other professionals with a basic understanding of groundwater that will help them make decisions on water-well design and operation. The manual covers geology, groundwater movement, groundwater quality, regulatory issues, water-well types and construction, pumps, water treatment, water-well problems, and groundwater recharge and storage.
