Water Conveyance Tunnels

Significant population growth and its concentration in major cities, combined with a better appreciation of environmental issues and protection, demand a better way to provide water and wastewater services. Cities around the world are eager to clean up their waterways and to secure the water supply needed for prosperity and progress.

Water is one of our most important resources, and its transport is a major concern in both the developed and developing world. Water conveyance systems move water and wastewater from points of collection to facilities for treatment, and finally for distribution or disposal. Water supply tunnels, aqueducts, intake and outfall structures, interceptors, trunk and drainage pipelines are major components of water distribution. Pumping stations and facilities for flow control, surge abatement, collection, storage, and disposal are also a necessary part of the system.

WSP designs and manages the construction of water-supply tunnels, aqueducts, CSO tunnels and offshore outfalls, and deep shafts in all ground conditions. Our experience includes geotechnical investigations and assessments, ground improvement, and tunneling design, including TBM, SEM and micro-tunneling, tunnelling in gassy or contaminated ground, and seismic engineering to keep water tunnels operable in the event of earthquakes or other disasters.

WSP offers complete advisory services for developing water conveyance systems, including planning, design, and construction management services. Our extensive experience includes the design and construction management of water and wastewater conveyance tunnels, pipelines, pump stations, flow control facilities, shafts, and special structures related to water and wastewater conveyance.
