The Village of Pugwash is a community of 750 fulltime residents, situated on the east side of the Pugwash Harbour. The Village did not have a central water supply system and the local groundwater was of poor quality.
The Municipality’s main objective was providing a safe, reliable source of potable water. The residents, businesses and institutions in and around Pugwash currently rely on individual wells to supply drinking water. Many of these wells are contaminated with dangerous metals, including arsenic, lead and uranium, as well as elevated levels of chloride, making the water unsafe to drink.
Limited locations in the area that could support a wellfield with the required quality and quantity of water. This resulted in the wellfield being approximately 12 km outside of the Village, and in an isolated area. This led to additional infrastructure requirements to support the wellfield and treatment plant, plus additional transmission watermain to reach the residents.
The funding was provided through 3 levels of government with deadlines that resulted in an aggressive design schedule.
Source water had a high turbidity, the solution was to install a liner in all three wells.
Construction took place in several phases resulting in 5 tenders/construction contracts.

Clean water for the community
WSP was retained by the Municipality to complete the Pre-Design and Detailed Design for the potable water infrastructure required to provide domestic water supply to the residents of the Village of Pugwash. The pre-design evaluated design options for the provision of an economically sustainable domestic potable water supply. The detailed design elements include a biological iron and manganese removal water treatment facility, treated water storage reservoir, approximately 22 km of water transmission system and water distribution system to service the entire village and outlying areas.
