City of Kamloops
A Catalyst for Change
In 2010, the City of Kamloops (the City) began the process of moving from a fixed rate water billing system to a metered rate billing system, with water meters installed at all residences and some commercial users in the community. The intention of this change was to help residents become more aware of the water they use and to encourage water conservation. Studies have shown that Canadians who live in homes that are metered use 39% less water than those who live in home that are not metered.
Installation of the water meters was substantially complete in 2015 and, as of 2016, the City has seen peak summer demand reduced by 29% and winter water usage reduced by 11% compared with the 2006 baseline, exceeding all near-term target for water conservation.
The Broader Impact
The City engaged Prism Engineering, sponsored by the BC Hydro Industrial Energy Manager program, to quantify energy saving from the reduction in water use achieved to date. The energy savings were calculated in accordance with the International Performance Measurement and Verification Protocol (IPMVP), and the methodology was reviewed and approved by BC Hydro Measurement and Verification (M&V) team. Energy savings were calculated across the Kamloops Centre for Water Quality (KCWQ) and booster pump stations.
The savings were determined for each location, and were consolidated for overall results. The graph below displays the trend of reduction in energy use for water distribution at City of Kamloops:
