Arlington Pre-Chlorinated Pipe Bursting

Speakers:  Jessie Allen, Senior Engineer-Operations, Arlington Water Utilities; and Al Meschke, Business & Educational Director-Texas, Murphy Pipeline Contractors


Arlington Water Utilities (TX) maintains over 1,440 miles of water mains in the distribution system, including 588 miles of existing asbestos cement (AC) pipe. In 2015, 72% of the 533 water main breaks were on AC water mains. Using an innovative approach geared towards reducing customer impact, minimizing capital spending and reducing operational costs, Arlington selected pre-chlorinated pipe bursting to install new HDPE pipe. Murphy Pipelines, which specializes in this technology, was awarded the project. To date, work has progressed replacing more than 13,000 LF of existing 6” AC water main with new 8” HDPE pipe. The majority of the work is in typical residential neighborhoods with a history of frequent water main breaks. Minimum construction related customer complaints have been recorded.
