Our Goals

As drinking water becomes a significant concern in our world, safety and sustainability are among the two most important issues.

The Victoria Park Water Treatment Plant is responsible for delivering safe drinking water to the Town of Truro, and subsidiaries, now and far into the future. We evaluate this through ample sampling regimes conducted daily, weekly and quarterly throughout our distribution system.

The Victoria Park Water Treatment Plant achieves these goals by keeping abreast of newly implemented drinking water regulations and technological developments associated with drinking water supplies and treatment methods. We also maintain continued education for staff in the field of drinking water which allows us to meet current and future federal and provincial drinking water mandates.

Historical Development

The Town of Truro purchased a water supply system in 1875 that was owned by the Intercolonial Railway. The supply system was an impoundment of Lepper Brook, located approximately 1500 m from the existing dam. In 1883, the wooden Tremaine dam was built approximately 750 m from the existing dam.

In 1898, the original impoundment was replaced by a facility that was built at the existing site. This raised the water level to 83.3 m. In 1940, the dam was raised and it increased the water level to 88.3m. Wells were drilled in 1948 to supplement the water supply capacity and again in the 1970Ùs.

In the early 1980's, it was discovered that some of the wells were contaminated from salt and dry cleaning fluid. An investigation in 1986 recommended that the water supply system be upgraded. Construction of a water treatment plant started in 1989. The water treatment plant was completed in 1991, and an expansion of the Lepper Brook dam and construction of a new pump house were completed in 1992. The new dam raised the full operating level of the reservoir to 97.5m.

Water Treatment Process

Raw lake water is pumped to the treatment plant. The lake water makes contact with an aerator before it gets pumped through screens at the main pump house. The aerator makes tiny bubbles that will increase the dissolved oxygen in the water and the screens remove debris such as sticks, leaves and fish.

Raw water enters two pre-mix tanks where chemicals are added and mixed rapidly. In the first tank, lime and potassium permanganate are added. The lime buffers the water or reduces its acidity and the potassium permanganate oxidizes the iron and manganese. As the water flows to the second tank, carbon dioxide gas is injected to buffer reactions.In the second tank, alum and polymer are added to cause the natural organic material and oxidized iron and manganese to clump together (or coagulate)and form particles called floc.

The floc particles then flow into the flocculation tanks. The water is mixed gently to allow the particles to collide and get larger in size and heavier.

The water then enters the large settling basins where conditions are relatively calm. This allows most of the large floc particles to settle, special plate settlers in the basins accelerate the settling process. The clear water flows out over the basin.

It then trickles through dual media filters. The media consists of sand and anthracite; they will remove all of the finer particles that did not settle in the settling basins.The filtered water then enters the chlorine contact chamber where chlorine is injected.The water flows through a series of passages designed to hold the water in contact with the chlorine.Chlorine is a strong disinfectant and will kill bacteria.A residual amount of chlorine remains in the water to keep it free from impurities.The disinfected water will then flow into another chamber where caustic soda is injected. The caustic soda reduces the waterÙs acidity to prevent erosion of the pipelines that carry the water.

The treated water is then distributed through a network of pipelines and storage tanks to the consumer.

Lepper Brook

In the mid 1980's, a long and detailed process began to develop a water resource management plan for the Town of Truro. It was apparent that a reliable water source was needed as the Town's population grew. The Lepper Brook watershed is one of the best municipal water supplies in Nova Scotia with an average yield of 3.65 million gallons per day. Located in the southeastern portion of the Community, the watershed is protected on all sides by development restrictions. In addition, the Town has introduced a new dam, pumping station, and modern water treatment facility. All treated water meets the Canadian Drinking Water Guidelines established by Health and Welfare Canada. At present, the Water Management Program is operating near 50% capacity with substantial room for growth.

The Town follows a four-step colour precipitation process for water treatment. By creating a chemical environment in the water, unwanted materials and organics separate as a precipitate. The disinfection of bacteria and other microbes with chlorine is then accomplished. The resulting water is clear but too acidic for human consumption, so Caustic Soda is added as the last step to reduce the acidity of the water to consumption levels.
