Abstract
In the case of the Niagara Region utility, we estimate that the annual unaccounted costs were between $10 and $35 million in 1998. This estimated range compares to a combined annual operating budget for the water and wastewater facilities of $64 million. Thus, our results indicate that the cost of water supply and sewage treatment is substantially understated by a factor of 16%–55%. Because of the commonality of accounting practices, we expect other Ontario utilities to be similarly underpriced.
