Case Study: Pipe bursting allows upsizing with minimal disruption

How do you replace 540 feet of sewer under a popular golf course without interruption to golfers, utility customers or street traffic?That was the question when part of an Eagle, Idaho, wastewater main, which ran beneath a fairway of the famous BanBury Golf Course, required upsizing.
