Water and sewer rates are projected to rise 5.5 per cent in 2018, with annual increases in that ballpark expected until at least 2027.
Rates are projected to go up between 4.4 per cent and 5.2 per cent annually over the next 10 years under a proposed financial strategy to pay for the upkeep of infrastructure.
(...)If council endorses the updated long-range financial plan pitched by the finance department, properties hooked into the municipal water and sewer systems would be paying more for drinking water and wastewater treatment, plus stormwater collection each year.
