Water is drawn from the Assiniboine River through a stainless steel intake structure located in the RM of Cartier. The water flows into a concrete wetwell on shore then submersible pumps convey the water to the water plant. Water can be taken directly into the plant or can be stored in a 60 million-litre pond east of the plant. This allows for pretreatment and for discontinuing use of the river when quality deteriorates, typically in mid spring and late summer.
A powerful oxidant, potassium permanganate, is added to the water to break down organic substances which contribute to the taste and odours. A coagulant may be added to assist in removing suspended sediment. Powdered activated carbon is added to absorb organics, again for taste and odour control. The water is pumped into the clarifier, where it is mixed with re-circulated sludge and a number of chemicals. Lime is added to increase pH (relative alkalinity) and which causes caronate “hardness” minerals and many other dissolved substances to precipitate out. Caustic soda is added occasionally for non-caronate hardness removal. Coagulant and polymer is added to bind precipitates and sediment together into a setteable “floc”, and powdered activated carbon is again added for taste and odour control. The clear effluent is conveyed into a recarbonation tank where carbon dioxide is bubbled through to neutralize the high pH. The water than passes through coal and sand filters and a small dosage of chlorine is added to kill pathogenic organisms (bacteria, viruses, etc). Fluoride is added for dental health purposes.
Reservoir and Pumping Station
Water is pumped via pipeline from the water treatment plant to a reservoir and pumping station in the RM of Headingley. The station consists of a reservoir with a storage capacity of 1,100,000 Litres of water. The station is equipped with electric pumps and one high capacity pump powered by a diesel engine to provide water service in the event of hydro interruptions. The high capacity pump also will provide large volumes of water to the fire hydrants in Headingley in the event of a fire. A standpipe for truck fill purposes is provided at the facility. The standpipe operates on a debit card system which may be purchased at the municipal office.
The water is tested for Chlorine residuals on a daily bases at the water treatment plant and at the Headingley reservoir as required under the Public Health Act.
Microbiological and Chlorine residual testing of the distribution system is conducted in three locations within the Municipality once every two weeks. Samples are submitted to an accredited Laboratory for analysis in accordance to the Public Health Act and Guidelines for Canadian Drinking Water Quality to ensure that the water being delivered to the public is safe for human consumption.
SEWAGE COLLECTION & TREATMENT
A low-pressure sewage collection system services the R.M. of Headingley. Household sewage is collected in individual household septic tanks. These two chamber tanks have solid sewage storage on one side and a liquid sewage pumping chamber on the other side. The liquid sewage is pumped to the sewage treatment plant by pumps servicing each sewage holding tank. The forcemain system delivering the sewage to the treatment plant is approximately 5400 metres long and is comprised of three sections with 200 mm, 250 mm, and 300mm diameter pipes.
