(pumping and treatment) burdened with complex operations and large per capita costs.
One feature of the small wastewater facilities is the discharge of effluents to a number of
freshwater lakes and streams with limited assimilative capacity particularly with respect
to the aquatic nutrients nitrogen and phosphorus. This potential issue is addressed in
Section 4, which describes the current and future wastewater treatment requirements
stemming from the IRP regulatory compliance driver.
Figure 3.2 presents an overview of the water and wastewater systems for the urban
Halifax area.

Water Supply Plants
When Halifax was founded in the mid-eighteen century, water was supplied to the
settlement by wells. In 1844, the Halifax Water Company (now Halifax Water) chose
Chain and Long Lakes as the source of water. In the early 1970’s, water consumption
was approaching the existing capacity of the Chain Lake system; Pockwock Lake was
selected as the new source water. The J.D. Kline WSP (Pockwock Lake) was
commissioned in 1977.
