Our treatment plants in Melfort, Wakaw, Gravelbourg, SaskWater also monitors most of our facilities and Edenwold, Meadow Lake, and Elbow use these types of customer facilities remotely. We have remote processes. monitoring equipment installed in 58 locations, which we either own or operate, allowing continuous facility surveillance. We monitor key water quality parameters, Groundwater equipment operation and water levels, pressures and flows. For groundwater, the treatment process generally consists of oxidation of iron, manganese and other minerals with aeration and/or other processes followed by detention, conventional or membrane filtration and disinfection.

Our treatment plants in Pierceland, White City, Melville and Cupar use groundwater sources with this kind of treatment process.

Monitoring Requirements

SaskWater undertakes water quality testing as required by The Waterworks and Sewage Works Regulations and by operating permits for our water treatment plants and distribution systems.

Transmission

The WSA also determines water quality aesthetic maintenance for potable water transmission systems. objectives, which apply to certain characteristics of, or There are no treatment facilities on any of these substances found in, water for human consumptive or transmission systems. hygienic use.

Key Drinking Water Parameters and Effects

As the regulator for water quality, the Water Security Agency (WSA) determines standards which are legally enforceable requirements for drinking water quality as per The Waterworks and Sewage Works Regulations. In general, standards are mandatory health parameters

Analysis is performed on a single sample for Total mg/L: Miligrams per litre Coliforms, E. Coli and Background Bacteria. All water- (equivalent to parts per million) works are required to submit samples for bacteriologi- cal water quality; the frequency of monitoring depends on the population served by the waterworks.

Precautionary Drinking Water Advisory

An advisory issued under the authority of Subsection 36(1) of The Environmental Management and Protection Act, 2010 by Water Security Agency Field Offices (WSAFO) when the WSAFO and Health Region determine that drinking water quality concerns exist but immediate public health threats have not been identified. As an example, it is standard protocol to issue a PDWA when a water main is depressurized to undertake repairs.

Trihalomethanes (THM)

Trihalomethanes are formed when chlorine reacts with organic matter in water. The four THM compounds are: chloroform, dibromochloromethane, bromoform and bromodichloromethane. The sum of the concentrations of these four components is referred to as Total Trihalomethanes. The limit for THM is a long-term objective based on an annual average of seasonal samples.

Water Disinfection

Regulations require a minimum of 0.1 mg/L free chlorine residual OR 0.5 mg/L total chlorine residual is required at all times throughout the distribution system. Individual Permits to Operate may specify a higher minimum required residual. An adequate chlorine is a result that in- dicates that the chlorine level is above the required mini- mums.

Summary of Situations where Permit to Operate Requirements Were Not Met The full details of the water quality for the facilities that SaskWater owns and operates are available in the Notice to Consumers posted to www..com. This section provides an overview of the instances where facilities did not meet requirements as laid out in their permit to operate. Other than these few instances, SaskWater owned and operated facilities meet or exceed water quality and sampling guidelines.

Emergency Boil Water Orders

There were no emergency boil water orders (EBWO) issued on any SaskWater owned or operated facilities in 2020.

Precautionary Drinking Water Advisories

A Precautionary Drinking Water Advisory (PDWA) is issued when drinking water quality concerns exist but immediate public health threats have not been identified. They are commonly issued as a result of power outages or mainte- nance that may result in depressurization of the distribution system.

There were four (4) PDWAs issued on SaskWater owned  The Jackfish Lake West Water Utility Co. had PDWAs potable water systems in 2020: issued on: February 19 due to a watermain break; July 8, July 7, and August 17, due to depressurization  Saskatoon Potable Water System – East caused by a power outage; and December 16, due had a PDWA issued on December 3, due to to a depressurization caused by a line repair. depressurization caused by an emergency leak repair.  The Village of Meota had PDWAs issued on: May 13, due to seasonal start up at the Meota Regional Park;  Buffalo Pound Water Supply System – North June 12 due to a water main repair; July 8, and West had a PDWA issued on March 6, due July 27 and August 17, due to a depressurization to a planned service interruption.

This is a non-potable water supply system developed to supply industrial customers; however, household users are also supplied and the water is unsuitable for drinking unless treated. SaskWater provides a Bi-annual notice to customers, reminding them the water is non-potable and information regarding the issued PDWA.
