Publisher's Synopsis
When repair and rehabilitation of existing infrastructure is necessary, many utilities employ techniques that reuse the existing conduit to reduce the impact to customers, existing surface facilities, and traffic flow. Pipe renewal operations are generally less expensive and less disruptive than open trench replacement; however, customers must still endure service disruptions and general construction environments. While infrastructure improvements ultimately benefit customers in the long-term, utilities benefit when they reduce short-term customer dissatisfaction. Repair and maintenance of existing distribution lines is an increasing concern for utilities. While pipe lining activities are effective and generally less expensive than complete replacement, they still represent considerable time and expense.
