Water and sewer services in Kamloops will cost you a little bit more over the next five years. The City of Kamloops will be increasing water rates by one per cent in 2023 with sewer rates going up 2.5 per cent, translating into a combined increase of $16 on average for a Kamloops homeowner. Utility Services Manager Greg Wightman says Kamloops has Canada’s most complex water distribution system owing to the topography and the way the city has grown through sprawl.
