Mishawaka, Ind.’s water department needed a valve installed on an existing 20-in. trunk line, but some conditions complicated the project. The trunk line had multiple broken valves that would not allow the water department to limit the scope of a service shutdown to the large community of users. The department very much wanted to avoid stopping service to the complete line. This dictated the use of an insertion valve system that could be installed while maintaining full pressure.
The village of Lombard, Ill., was in the middle of a major project to add improved water service to an important commercial and residential area. With pipeline extensions well under way, the village planners needed to prepare for the joining of the new components with the existing system.
