✦ Synopsis

The purpose of this technical note is to summarize results from a survey of water utilities regarding preferred lead pipe rehabilitation and replacement techniques for small diameter (<25 mm) water service pipes. The survey results are based on responses from 23 water utilities ranging in size from 26,500 to 4,656,OOO m3/d in North America, Europe and Japan. In North America, survey respondents indicated preferences for the open-trench, pull-through, and moling technologies. In Europe, respondents indicated preferences for the open-trench and moling technologies. In Japan, respondents indicated overwhelming preference for the opentrench technology. Results from this survey were used to identify factors affecting the performance, advantages, and limitations of each technology.
