Our Water and Wastewater team includes professionals that specialize in the design and construction of municipal linear infrastructure . Our experience ranges from the replacement of 150mm diameter watermains in congested urban streets to large diameter transmission mains constructed in open cut or tunnel.
Our Linear Infrastructure team has designed thousands of kilometres of watermains and trunk transmission mains for municipalities across the country. One of the unique specialties of our team is the design of large diameter pipelines, including transmission feedermains up to 2400 mm in diameter. We have been responsible for the design of new pipelines, pipeline replacements and relocations required for new infrastructure such as bridges, underpasses and LRT trackways.
Our Linear team has designed watermains installed by open cut construction techniques as well as a variety of trenchless techniques including tunnel boring machine (TBM) tunnelling, microtunnelling, jack and bore tunnelling, and horizontal directional drilling.
Our Linear Infrastructure team has extensive experience and expertise in the design and construction of watermain rehabilitation using the cured-in-place pipe (CIPP) method. Our team is currently managing the City of Toronto’s rehabilitation program, which is one of the largest programs in North America, lining approximately 40 kilometers of aging cast iron pipes every year. We have also completed several large diameter trunk watermain lining projects using CIPP.

Potable Water Storage
A critical part of each municipality’s water network is water storage. At WSP we have planned, designed and constructed some of the largest potable water storage facilities in Canada. We understand the importance of water storage in the management and design of resilient municipal water infrastructure. From over 10 ML elevated storage to over 150 ML in ground storage we have been a part of and understand the challenges in building large water retaining structures. Our experience also includes planning for water storage in some of our coldest climates and challenging conditions. Sometimes the most challenging water storage projects are the smallest not the largest.
We don’t just build new storage infrastructure but rehabilitate existing storage. WSP has extensive experience in the structural rehabilitation and upgrades of existing reservoirs to ensure the longevity of the facility and security of the water supply.
WSP is a market leader in the design of water pumping stations for transmission and boosting of potable water flow. The world of potable water pumping offers many opportunities for clients to provide a significant juncture to their water infrastructure providing resilience and support to the entire piping and distribution system. WSP has extensive experience in the layout and design of a range of pumping facilities and is always striving to incorporate new ideas and technology into our stations and work with our clients to provide the gold standard to the public we serve.
Maintaining a safe steady drinking water supply to residents is at all times the primary objective, however through the course of our project work there are occasions where detailed staging and coordination of services is required to complete the project, which may also require the introduction of bypass pumping to completely isolate the facility to allow the work to proceed. WSP has carried out the design and coordination of bypass system.
Hydraulic and transient modelling of pumping systems is unique art in itself that when done correctly will highlight areas of concern with in your pumping system and allow WSP as the designer to adjust the layout and features of the system to alleviate any risk to the Clients infrastructure caused by transient surge or other hydraulic events and stresses.
Plant and Pump Station Hydraulics
WSP provides advanced hydraulic solutions for process and flow control challenges in plant and pumping systems for the water, wastewater, mining, hydropower and industrial sectors around the world. We offer a full range of services from conceptual studies to detailed design, commissioning or performance monitoring for process piping in plants and pump stations and for pipelines conveying water, sewage, acids or slurries. We also specialize in fluid transients (water hammer) and 3D numerical or scale models.
Water systems require a high degree of reliability to maintain operation. At WSP, we use the most advanced modelling tools available for piped systems to accurately predict performance under normal, peak and emergency conditions, reducing capital and life cycle costs. We also use in-house sensors to check real-world performance, optimize energy use and monitor processes
Upwards of 80 % of the capital cost of water and wastewater infrastructure is tied up in pipe networks; similarly a significant proportion of operating cost derives from the operation and control of networks. Even so, many water utilities still only have a rudimentary understanding of how their networks really behave. Gathering operations, planning and maintenance data along with GIS information system attributes and other data into one single tool, a model that simulates or parallels as close as possible the behaviour of actual operating conditions of the networks, can allow asset managers to make the right decisions at the right time. The advent of cheaper and more precise system sensors and monitors will allow even more focused operation and even prediction of events to help ensure the necessary supply resilience and optimized costs.
