Rehabilitation of Water Mains (M28), Second Edition

• Cleaning: You'll find information and procedures for flushing, cable-attached devices, pigs and other fluid-propelled cleaning devices, and power boring devices.
• Lining: You'll get technical advice and data about cement-mortar lining, epoxy lining, conventional slip-lining, close-fit slip-lining, and cured-in-place lining techniques. Additionally, you'll get information about Class I, II, III, and IV (nonstructural, semistructural, and fully structural) linings. You will learn which linings will perform best under different internal pressure loads. Installation of internal rubber joint seals is also covered.
• Replacing: Find out about trenchless pipe replacement using pipe-bursting technology, a replacement method for pipe varying in diameter from 4 in. (102 mm) to 48 in. (1,219 mm) which can be less costly than conventional dig-and-replace operations.
