Addressing the Achilles' heel of an aging collection system

摘要

After experiencing two back-to-back costly infrastructure catastrophes, the Warwick Sewer Authority (WSA) could not endure another. Knowing that its main influent pipe, which runs beneath Interstate Route 95 (1-95), was showing signs of age, WSA put its rehabilitation on the high-priority list. Although it took years to complete the project, WSA persevered and completed the job in 2015. This article tells the story of this project, including lessons learned, with the hope that other water utilities will choose the same proactive approach and avoid the financial and operational pains endured by WSA as a result of previous critical infrastructure failures.
