The Anthony Henday Water Treatment Plant is classified by Alberta Environment as a Class III Water Treatment facility. Water is treated, stored, and pumped to the six communities.

The Red Deer River is the source of water for the AHWTP, which originates in the Rocky Mountains east of Lake Louise. The Little Red Deer River and Medicine River are the two main tributaries which enter the Red Deer River upstream of the AHWTP. Due to their different watersheds, each can contribute different quality characteristics to the raw water during spring run-off and during periods of heavy rain. Raw water during these times can exceed 8000NTU (a measure of clarity) and 200 True Colour Units.

River water is drawn into the Low Lift Pumphouse and is pumped up to the Water Treatment Plant. A large in-line strainer, removes debris

from the water, and Potassium Permanganate can be added to aid in removing colour and organics. In the

Water Treatment Plant, a coagulant is added for settling of solids and organics removal, Powdered Activated Carbon is added for taste and odour removal, and chlorine is added

At the end of the process for disinfection to kill any pathogenic organisms, bacteria, and viruses.

In the WTP, there are five process trains, which utilize membrane ultra-filtration technology for the treatment process. In each train, there are six membrane cassettes. These cassettes are immersed in the water in the process tanks where water is drawn through the membranes under a low vacuum by the permeate pumps. The treated water (permeate) is disinfected with chlorine and discharged to the Clearwell. Typically the treated water has a turbidity of less than 0.10 NTU.

Treated water from the Clearwell is pumped to Innisfail via a 250mm pipeline, and water pumped to Bowden, Olds, Didsbury, Carstairs, and Crossfield is done via a 400mm diameter, 80 km long pipeline.

Tests, such as Chlorine residual, turbidity, and p.H. are done on site on the raw and treated water in the Plant Laboratory. Bacteriological quality testing is done independently at the Provincial Lab of Public Health.

Total Plant production is 27,000,000 Litres of water per day.
