Description of the Water System

 

The Town of Gillam Water System provides potable drinking water to a population of 1317 residents (2011 Census) as well as several bulk water customers and numerous visitors to the community.

 

Treated water produced from the water treatment plant meets all health and aesthetic objectives as stated in the Guidelines for Canadian Drinking Water Quality.

 

Water Supply Source

 

The primary source of water for the Town of Gillam is Stephen Lake. The pumping station, located at Pump House Beach, was retrofitted with new pumps and controls in 1997. Raw water to the Water Treatment Plant is pumped by two 50HP electric pumps.

In the event of a power failure this pump house has a 120HP diesel pump that can be started to supply water to the Water Treatment Plant.

 

The secondary source of water for the Town of Gillam is the Kettle River. In 1997 new controls were installed with number 1 pump replaced in 2007 and number 2 pump replaced earlier this year. Both pumps are electric 15HP.

 

Water Treatment Process

 

The Water Treatment Plant is designed to treat raw water for the removal of color, odor, taste, turbidity, micro-organisms, and other impurities to provide a high quality effluent for potable and domestic use.

 

The plant combines the advanced design feature of high rate filtration with the time proven principles of flash mixing, coagulation and dissolved air flotation prior to filtration.

 

The treatment process is completely automatic, gravity flow operation incorporating: a flash mixer, two stage variable speed mechanical flocculator, dissolved air flotation ( DAF) and two rapid gravity filters composed of sand and coal media.

 

The Gillam water treatment process contains two treatment trains. Each train consists of a DAF unit and two rapid gravity filters followed by chlorination, fluoridation and pH control.

 

Distribution System

 

Water is supplied to the distribution system by three 50HP pumps located on the ground floor of the Water Treatment Plant. In the event of a power failure there is a 200HP diesel generator that starts automatically providing power to run the DAF’s and distribution pumps until Hydro power is restored.

 

In the event of a fire, where a great volume of water is needed, there is a stand-by 120HP fire pump in the Water Treatment Plant.

 

Storage Reservoir

 

There is one treated water reservoir with a capacity of 1,409,287 liters (310,000 imperial gallons).

 

Classification and Certification

 

Under the Water and Wastewater Facility Operators Regulation our operators are required to be certified to the same classification level of the water treatment facility.

 

- Class III Water Treatment Facility Classification

- Certification Level of Operators:

·        Jesse Taylor Class IIII Operator

·        Dino Friesen Class II Operator

·        Howard Kirkness Class II Operator

-         Steven Beardy Class II Operator

-          

Disinfection System in Use

 

The final step in the treatment of safe water is disinfection. Disinfection is the selective destruction or inactivation of potential disease causing organisms in water. As per the Drinking Water Safety Act the Town of Gillam must ensure that a disinfectant residual of at least:

·        0.5 mg of free chlorine per litre of water is detectible at the point where water enters the distribution system, after a minimum contact time of 20 minutes.

·        0.1 mg of free chlorine per litre of water is detectible at all times at any point in the distribution network.

 

Type of disinfection system used

 

The Town of Gillam disinfects using 12% sodium hypochlorite (liquid chlorine) in 114kg drums.

 

Equipment redundancy and monitoring requirements

 

As required by the Drinking Water Safety Act the Town of Gillam ensures continuous disinfection is maintained at the plant by keeping in stock all spare parts required for the chlorinator.

 

Disinfectant residual overall performance / results

 

Disinfectant residuals are monitored daily at the water treatment plant and bi-weekly in the distribution system and recorded on the appropriate monitoring forms. Monthly chlorination report forms are sent to the regional Drinking Water Officer at the end of each month.

 

 

Bacteriological Monitoring and Reporting

 

The Town tests for total coliform and E coli bacteria every two weeks. In 2016 the system was 96% compliant with Bacteria sampling frequency requirements and 100% compliant with Bacteria sampling results.

 

Physical Monitoring and Reporting

 

Turbidity is a measurement of the clarity of water. We use turbidity to tell us how well our treatment system is working and to remove particles and other contaminants that can cause the water to look cloudy and affect our disinfection processes. Turbidity is tested daily as the raw water enters the treatment facility and after each filter.

 

The filters at the water treatment plant are not meeting provincial standards. Engineering plans will address upgrading our system to meet provincial standards.

 

Disinfection By-products Monitoring and Reporting

 

Trihalomethanes (THMs) are formed when chlorine reacts with naturally occurring organic matter in the water. Studies have shown a link between high levels of THMs and cancer. For that reason the province has set a health based standard for THMs of 100 micrograms per litre of water. The THM standard is based on an average of four samples per year.

List of Water Quality Standards

Parameter

Quality Standard

Total coliform

0 total coliform bacteria detectable per 100 ml in all treated and distributed water

E. Coli

0 E. Coli bacteria detectable per 100 ml in all treated and distributed water

Chlorine residual

-a free chlorine residual of at least 0.5 mg/l in water entering the distribution system following a minimum contact time of 20 minutes

-a free chlorine residual of at least 0.1 mg/l at all times at any point in the water distribution system

Turbidity

-less than or equal to 0.3 NTU in 95% of the measurements in a month of the effluent from each operating filter

-not exceed 0.3 NTU for more than 12 consecutive hours of filter operation

-not exceed 1.0 NTU for any continuous measurement

 

 

Water Chemistry Analyses

 

The Gillam Public Water System performs daily and bi-weekly, quarterly and annual tests in order to ensure compliance with regulations.
