Water and Environment

Municipal wastewater discharge was polluting Ladysmith Harbour, a sensitive receiving environment valuable to the local community, First Nations and the shellfish industry. The Town of Ladysmith required a treatment strategy that would satisfy environmental regulations and serve a growing population.

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.

 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.

The potential of human health risks had to be properly investigated, remedied and results communicated to the stakeholders during the renovation and redevelopment of a former industrial area that has been rejuvenated  into a thrilling and sought after area in Washington D.C.

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.
