Water utilities often do not know the specific cause of external corrosion observed on their water mains, and consequently, the chosen preventative measure may not work effectively. Historically, these choices are based on data from other industries (e.g., gas and oil) and may not be suitable for the water industry. Corrosion of metallic pipes can be caused by a variety of mechanisms, each of which requires a different solution. Determining which corrosion mechanism is at work is not a simple matter, because the resulting pipe damage looks similar for all of them. The failure to properly identify corrosion sources may produce prevention systems that are ineffective or do not last. For example, it is not effective to install an anode bag on a main that has a bacteriological corrosion problem. Similarly, an anode bag installed to reduce corrosion caused by a stray impressed current would be quickly used up and would provide only short-term protection. Much recent research on corrosion has focused on internal corrosion, primarily related to water-quality issues, such as lead and copper control and red water. This project will examine external corrosion, which affects the structural integrity of the pipe and makes it vulnerable to leaks and breakage. After identifying the causes of external corrosion, the study will find economical solutions for each type of corrosion and verify them through field trials.

This report was designed to give utility manages the guidance to help them develop an appropriate pipe cleaning program. The report present criteria, flow charts, and tables to assist in selecting pipes to be cleaned and the most appropriate cleaning methods to employ. Equipment and labor costs, disposal of water sediment, customer service and other influences are also discussed. Case studies from the 100 utilities surveyed help to demonstrate results.

This manual provides guidance to water utilities and public health agencies, showing how to set up locally responsive water surveillance programs. It examines two major settings which surveillance must address and their appropriate responses: variations occurring in plant operation or distribution systems, and the detection of disease in the community. A proactive approach is described, involving watershed monitoring, record maintenance, and planning for emergencies. Material on public health recommends augmenting laboratory-based notifiable disease surveillance and creating or improving an emergency room-based sentinel system. A communications and action plan in case of outbreak is outlined. Emde is affiliated with the Northern Alberta Provincial Laboratory of Public Health, Canada. This work lacks a subject index. c.

A typical water distribution system is complex and chaotic with varying piping configurations, water flows, chemical reactions, and microbiological activity. It is therefore no surprise that monitoring water quality can be a daunting task, not to mention dealing with the devastating and costly effects of: Noncompliance with the Lead and Copper Rule Pinhole leaks in water service lines and private plumbing Vulnerability to microorganisms in the water distribution system Unwanted side effects from treatment chemicals Mistakes in treatment chemicals and dosage amounts These common water quality issues can be avoided by routinely monitoring key water quality parameters in the distribution system in a controlled and standardized manner. While proactive monitoring costs money, having water quality problems is even more costly. Water Distribution System Monitoring: A Practical Approach for Evaluating Drinking Water Quality provides a practical step-by-step approach and open-source technology for proactive water quality management. It describes a method for routinely monitoring the water distribution system by: Assembling a standardized monitoring station Planning a monitoring strategy, and Interpreting and using the water quality data Deliver safe and economical drinking water to your customers. Why wait three years to find out if the water system is in compliance with the Lead and Copper Rule? Why guess which corrosion control chemical is the right one? Why guess how much disinfection is needed in the water distribution system? Optimize your chemical usage, minimize your operational expenses, and confirm that the water is safe. Laying out a path to quality control and process improvement, this book provides the tools for well-defined and measurable control of water quality.
