Welcome to the McKay Water Treatment Facility

1 Welcome to the McKay Water Treatment Facility The Naramata Water Advisory Committee (NWAC), the Regional District Okanagan Similkameen (RDOS) and Area Director Tom Chapman are pleased to welcome you to today s open house. NWAC, RDOS and Director Tom Chapman would like to recognize the Province of British Columbia, the Ministry of Community Services and the Federal Government for their funding to make this project a reality. SOME REMINDERS The RDOS will be conducting guided tours of the facility starting at Noon and ending at 3:45 Saturday March 24th and Sunday March 25th The RDOS is hosting a complementary Barbeque with new Naramata water so please enjoy Please do not enter the facility without an RDOS representative Please keep an eye on your children and follow the instructions of RDOS representatives For additional information please visit our website at or contact the RDOS

2 The Naramata upgrades The RDOS has undertaken upgrades to allow Okanagan Lake water to be the sole source of raw water for treatment for residential homes. Naramata s upland creek intakes will be kept as backup for domestic drinking water and will provide the primary source of irrigation water when the system is split. Pumping Plant beside Wharf Park A new pumping plant with increased capacity has been installed beside Wharf Park. Now water for the Naramata system comes from one intake. The intake head was expanded to allow for the increase in water drawn through the pipe. New Water Main Lines To meet the higher volume of water, new water mains were placed between the Wharf Park Pump house and the McKay Water Treatment Plant. Distribution lines were also upgraded along the construction route. In total 4.4 km of pipe was installed. McKay Water Treatment Plant The MacKay Road Reservoir was expanded to include a treatment plant. The new plant includes Ultra- Violet (UV) treatment, an innovative chlorination system and a energy saving heat exchanger. Future Plans: Splitting the System RDOS and NWAC will begin detailing the plans to split the system into treated lake water for residential homes and untreated creek water for irrigation. The goal will be to progressively split the system by replacing old pipe with two new lines. Splitting the system will allow the Naramata water system to retain upland water rights while saving pumping and treating costs for irrigation water.

UV Reactors 2) Ultra-Violet (UV) Reactor Cells expose the water to high intensity UV rays. UV Rays deactivate harmful organisms such as Cryptosporidium and Giardia which are resistant to chlorine treatment. Interior of a UV Reactor

The solution is pumped to the Sodium Hypochlorite injection point. 2) In the Electrolytic Cell, brine is mixed with softened water and a DC voltage is applied. This creates Sodium Hypochlorite (NaOCl) and Hydrogen. The Sodium Hypochlorite is pumped to the Storage Tanks at 0.8% dilution. Brine Tank Salt Loaded Here 1) Salt is added to the Brine Tank. Water at the bottom of the tank makes a Brine solution pumped to Electrolytic Cell.

5 OPERATOR STATION and Main Digital Control Panel provide controls for the entire system Treated water is run through a HEAT EXCHANGER which can either supply or remove heat from the outside air. This saves energy and money in heating or cooling the building. DISTRIBUTION PUMPS supply water to higher elevation locations. The pumps are activated based on the system demand.
