WSP provides holistic solutions as well as advisory and engineering services that focus on the full spectrum of water and wastewater management issues in the natural and built environment.  Employing methods and tools capable of assessing infrastructure system vulnerabilities, we help clients build more resilient water infrastructure, while minimizing capital spend and managing risks associated with the impacts of socioeconomic factors and climate change. 

 Infrastructure is needed to supply citizens, communities, businesses and industries with potable water, as well as to collect, treat and discharge wastewater to manage storm water runoff, and to prevent flooding. The effects of climate change are evident as cities and countries across the world increasingly experience more frequent and severe occurrences of extreme weather conditions. These effects have caused ocean, lake and river levels to increase and have spurred severe storms, floods and acute droughts—all of which threaten water sources, overtax infrastructure and make water infrastructure more vulnerable.

Effective and resilient water infrastructure is critical to public and environmental health, and to economic sectors worldwide, including pharmaceutical, agricultural and service industries. Disruptions in, or loss of, water or wastewater services; declines in water quantity and quality brought about by inadequate systems; major water disasters caused by floods and pollution, or as a result of under investment in water infrastructure management, pose risks to public health, economies and the environment.

Risks to public health, economies and the environment can include disruptions in, or loss of, water or wastewater services; declines in water quantity and quality brought about by inadequate systems; major water disasters caused by floods and pollution; or result from under investment in water infrastructure management.

Neglecting to earmark sufficient funds, deferring maintenance and not prioritizing investment to develop, maintain, repair and replace water and wastewater infrastructure has led to severe ramifications in both developed and developing countries. From water contamination crises in Flint, Michigan, Walkerton, Ontario and Mutare, Zimbabwe, to inadequate sewage treatment plants treating discharges to the Yamuna River in India, the importance of managing water has never been more critical. Additionally, according to the United Nations World Water Development Report 2016, nearly 30% of global water abstraction is lost through leakage in water supply systems.

Public agencies, utility owners and operators are trying to bridge the gap between current and future water supply demands, as well as finance the operating and capital costs to sustain and create more resilient water infrastructure. Under increased and unprecedented pressure to do more with less, and to find new means of paying for infrastructure, water owners and operators recognize that it is essential to understand and optimize the capacity of their assets.

WSP can respond through robust, innovative and appropriate long-term planning and engineering solutions, from the routine to the truly revolutionary, to help them adapt and meet current and future challenges.

Helping Stem the Strains on Water and Wastewater Infrastructure

Developing holistic and adaptable plans for the management and delivery of optimal and efficient water and wastewater infrastructure projects requires an understanding and knowledge of the natural and built environment, topography, resources, socioeconomic and even political factors. This includes retrofitting existing infrastructure to ensure systems can cope with the forthcoming demands of climate change.

WSP provides integrated water resources planning, design and engineering, and management to optimize solutions for water supply, alternative sources, storm water and wastewater management and reuse of reclaimed wastewater. We also have experience in advanced water treatment technologies, including desalination of seawater and brackish water, and zero-effluent discharge systems for power facilities.

Our water and wastewater infrastructure project experience spans the planning, design and construction management of large diameter pipelines, sewers, outfalls, water and force mains; separate and combined collection systems; pump and overpressure stations; flow control facilities; and special structures related to the storage, transmission and conveyance of raw water, potable water, wastewater, storm water and reclaimed water. We also provide modelling, analysis, design and construction management services.

Pasto water and wastewater masterplan, colombia

WSP provided Empopasto (entity in charge of the water and wastewater services in Pasto, Colombia) a full diagnosis of the supply, treatment, distribution and sewer systems, and developed hydrological and river quality studies to identify existing bottlenecks and primary problems related to the public water services provided to the community.  Taking in account growth tendencies, climate change and new technologies, WSP then developed feasibility studies and built a 30-year investment plan identifying the main projects needed to guarantee proper water supply, distribution and disposal services in the short and long term.

Water for Agriculture

A growing world population and rising consumption of natural resources place increased demands on agricultural systems charged with supplying global communities reliable and nutritious food. A core element of the agri-sector solution lies in using new technologies and expanding infrastructure to provide a reliable water supply at an appropriate quality standard for crop and animal production. Fit for purpose infrastructure is essential for rural enterprises to function in an efficient, effective and compliant manner—both on-farm and throughout the supply chain.

In New Zealand, WSP has a long history of applying skills and expertise to agri-sector infrastructure projects. From government policy support, land use studies and irrigation scheme concepts, to detailed design, funding, consenting, contractor procurement, asset management and performance optimization, the WSP Water for Agriculture team has established a track record for delivering infrastructure solutions from start to finish.

WSP in Colombia also has a long history in Water for Agriculture. With more than 120,000 ha designed, we are one of the preferred allies for the public and private sector for developing irrigation and land development projects for agriculture.

WSP’s work also extends to external market evaluations, in which the team identifies multiple opportunities.

Water Conserv II, Florida, US

WSP’s ongoing work as engineering consultant for the Water Conserv II project in Orange County, Florida, US is a case in point. When faced with a need to expand wastewater treatment service and a regulatory requirement to eliminate wastewater discharges to surface waters, the City of Orlando and Orange County formed a long-term partnership to develop Water Conserv II, an innovative water reclamation and reuse program.

Water Conserv II—the largest project in the world of its type— turned a potential liability into a beneficial resource by providing 35 MGD of reclaimed water for agricultural and residential irrigation and aquifer recharge, while providing an environmentally sound and economically feasible regional solution to previously discharged wastewater effluent. For more than 25 years, WSP has been providing water resources services for planning, permitting, design, construction management, operations and system maintenance.


To improve the quality of a water course in Widnes, UK, United Utilities commissioned WSP to develop an underground 16,500 m3 detention tank to reduce discharge of storm sewage from combined sewer overflows. WSP developed a precast, rectangular, concrete tank of modular design measuring 135 m x 42.1 m x 3 m-high—a UK first for a large, storm detention tank. The approach taken not only provided the client with the lowest whole-life cost—with an initial capital savings of around £1 M—but also generated a shorter construction program with less noise, dust, vibration and site traffic impacting the local community. The scheme was shortlisted in the Large Project category of the 2017 ICE North West Awards.
