South Surrey Interceptor Johnston Road Section - Phase 2Trenchless Segment

摘要

South Surrey Interceptor (SSI) Phase 2 Johnston Road is a twinning project to increase sewer conveyance capacity in Surrey, British Columbia. The SSI collects sewage from South Surrey and Langley, and conveys it to the Annacis Island Wastewater Treatment Plant. The two-phase, (US)$14 million South Surrey Interceptor (SSI) appears to be the largest diameter microtunnel project completed to date in North America, at a 3.68-m machine diameter. The project illustrates how microtunneling can be successfully used to efficiently complete large diameter curved pipeline installations in urban areas, while minimizing disturbance and environmental impacts.
