The two-phase South Surrey Interceptor is the largest diameter microtunnel project completed to date in North America

The South Surrey Interceptor (SSI) was constructed in the 1970s to convey sewage from South Surrey, White Rock, and Langley, BC to the Annacis Island Wastewater Treatment Plant. Metro Vancouver began twinning the SSI in 1999 to increase capacity for BC's rapid growth and improve environmental protection by reducing sewer overflows.

The Johnston Road section was constructed in 2018 and 2019 as one of the final portions of this twinning project. Our geotechnical and environmental engineers, tunneling specialists, environmental scientists, and archaeologists worked with Metro Vancouver's engineering and capital project teams on the installation of a large diameter sanitary interceptor sewer. Constructed under a busy arterial road and through existing commercial and industrial properties, the design also incorporated solutions to reduce public and worker risk exposure during construction. Our team provided construction and contract administration services to facilitate completion of one of the most important sewer systems in British Columbia.

The newly built sewer utilized the largest diameter microtunnel boring machine used in Canada and North America to date. This project illustrates how microtunneling can be used to efficiently complete large diameter curved pipeline installations in urban areas while minimizing disturbance and environmental impacts.
