Water Supply and Reuse

Part of the ambitious and innovative Potomac Water Supply Program, the state-of-the-art facility will turn 40 million gallons of raw water a day, pumped directly from the Potamac River, into potable water supply.

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.

The state-of-the-art water reclamation facility will create a new drought-resistant water source for the region and replenish the local groundwater basin, while providing opportunities for community education.

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.

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.

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.

Prior to this project, residents of Harrington Harbour, a village in the province of Quebec, Canada, never had access to proper drinking water.
