Proposed Emergency Water Supply
The City has taken a number of steps to safeguard the quality of water supplied to City water utility customers. These steps include:
- Construction of the Kamloops Centre for Water Quality, a membrane water treatment facility.
- Maintenance of an appropriate disinfection residual in the water throughout the distribution system.
- Completion of cleaning of the distribution system through a uni-directional flushing program.
- On-going program of cross-connection control to protect the system from the introduction of unwanted substances.
Efforts have also been directed toward understanding and managing the Lower South Thompson watershed. However, it is recognized that despite those initiatives and efforts, the River Street Water Intake is at risk of contamination in the event of a major chemical spill into the South Thompson River, which is flanked by the CP and CN railway lines and the Trans Canada Highway.
Based upon assessment results, the risk level for the River Street Water Intake has been rated at moderate to high. It is therefore recognized that an emergency water source is required for the City to more fully safeguard its citizens and property in the event of a major spill, or a major process failure at the Kamloops Centre for Water Quality.
To address this risk, the City wishes to establish an emergency water supply from the North Thompson River to ensure continuous water supply to the residents of Kamloops in the event of such an emergency. The proposed location for the Emergency Water Intake is on the west bank of the North Thompson River near the end of Yates Road (Figure 1).

New infrastructure that would be required for the Emergency Water Supply would include a wedge style water intake on the bank of the Thompson River, an adjacent pump house with chlorination facility, and interconnecting pipes from the intake to the pump house and then out to Westsyde Road (Figure 2).

Modifications to the primary High Lift Pump Station at River Street would also be required to then back-feed emergency water from the North Shore area and further distribute to the south and southeast sectors of the City.
The proposed emergency water intake would only operate under an emergency shut-down of the City's primary water supply, so no additional water would be diverted from the Thompson River system as a result of this proposed project.
If approved, this proposed project would be scheduled for construction in 2015.
If you have any comments or concerns regarding this important project please contact us with your concerns.
