TRENCHLESS IN SAN DIEGO
When a study of San Diego's Middletown trunk sewer revealed flows in the line far greater than its design capacity, the city of San Diego accepted the lowest microtunneling bid for pipeline replacement. The conventional open-trench installation had a lower price tag, but higher "social costs," such as surface disruption, construction hazards, loss of revenues for local businesses, and inconvenience to commuters. This article explains the microtunneling technology, describes the methodology used in San Diego, provides information on clay pipe selection, and reports on the obstacles encountered by the mole. Factors that must be considered when designing a microtunneling project include soil conditions, pipe materials, size of pipe, length of pipeline and grade, environmental constraints, and social impacts.
