Pipe bursting system ends blockages
Problem
Roots protruding through joints and cracks in a 110-foot section of 4-inch vitrified clay sewer pipe created blockages at a mobile home park in Sunnyvale, Calif. The park owners looked for a permanent fix.
Solution
Maintenance supervisor Bob Smith contracted RODDIE Inc. to replace the line with 4-inch SDR-17 HDPE pipe using the company’s PB-40 pipe bursting system. The compact, 120-pound machine fit easily in the small pulling pit sandwiched between structures. A 13 hp low-pressure hydraulic power pack powered the ram with 50 tons of pulling force and 21 square inches of piston area.
Result
Sewer service was restored
