Water and Environment

WSP has been providing consulting services under successive contracts over more than 20 years to provide water resources services for permitting, design, construction, operation, and maintenance of the system.

 The 17-ft diameter storage tunnel of reinforced concrete segmental lining about 2.1 miles long, resulted in the elimination of CSO discharges to North Dorchester Bay.

System design manages impact on potable water supplies and post closure groundwater conditions.

The assessment of the pipelines in Salem Harbor found areas of advanced corrosion with an imminent need of replacement to avoid potentially devastating environmental consequences and service disruption. The project marked the first major subsea sewer in New England installed by the “float and sink” method.

New conveyance tunnels bring treated water from the Croton Water Treatment plant to areas in the Bronx and Manhattan.

Chemical manufacturing at the site used remnant mining pits as process lagoons and storm water holding ponds receiving process water overflows. We completed remedial investigation of soil, sediment, surface water and groundwater that identified large volumes of contaminated source material resistant to chemical, biological or physical treatment. WSP USA conducted the removal action to consolidate contaminated soil and sediment under the cap of a process lagoon converted for use as a disposal cell.

Meeting the water demands for one of the nation’s largest metropolitan areas presents a number of challenges from groundwater and surface water availability to pumping capacity to quality of water. We aid the city in addressing and maintaining existing supplies and developing additional groundwater supplies.

Florida’s water management districts maintain the state’s sustainable groundwater supply and regulate withdrawals from that supply for consumptive use. In 2006, three of the districts identified a region in Central Florida where supplies were expected to be insufficient to meet future demands. The three districts decided to jointly develop a regional water management plan.

Close coordination and communication among team members, the Bermuda government and the Bermuda Electric Company has been instrumental to successfully achieving project milestones to support the solar energy procurement process.

Posing hazards to public health and the environment, we removed toxic contaminants and transformed this old mining site into a popular destination for nature enthusiasts and clean energy investment.
