Nearly 80% of all utilities, and most smaller systems, derive their source water from groundwater. Understanding the occurrence and behavior of groundwater and the impact is critical.
This manual is intended to provide a general overview to help operators and engineering staff make decisions on design, installation, phasing, and repair needs for treating and managing groundwater.
Among the major changes included in content from prior editions are the incorporation of the well construction standards formerly attached to Standard A100 Water Wells and a discussion in...

Fiberglass pipe is used in many industries for myriad applications. Its durability, strength, and corrosion resistance eliminate the need for interior linings, exterior coatings, and cathodic protection. Fiberglass pipe systems offer great design flexibility, and fiberglass pipe is available in a multitude of diameters ranging from very small to very large. M45, Fiberglass Pipe Design, delivers both technical and general information for the design, specification, procurement, installation, and understanding of fiberglass pipe and fittings
Extensively illustrated, M45...

As more water systems turn to safer alternatives to chlorine gas, the generation of hypochlorite on site has become increasingly common. M65, On-Site Generation of Hypochlorite, presents the principles of on-site generation (OSG), the differences between low-strength and high-strength OSG systems, and the subsequent impact each of these systems has on design, construction, and maintenance for water and wastewater utilities. M65 provides operators and engineering staff with a basic understanding of how to design and install both low- and high-strength OSG systems, how they work, and how they...

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. This manual also covers 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...

Effectively managing valves as an asset can have a significant impact both for the water utility and the customer. This revised manual covers valve selection and installation as well as the importance of location, condition, and frequency of operation.
The updated figures show commonly used valves and their components, including: globe; butterfly; plug; ball; cone; and gate. Special-use valves are also discussed, but the intent here is only to introduce their availability and applications.
The authors incorporate the latest methodologies and technologies for...
