There’s a lot of talk about how much sewage treatment is going to cost, but how are we going to pay for it?
The only fair way is to charge each household based on how much wastewater they produce. Many municipalities in Ontario, from Windsor to Ottawa, have decided that water consumption is a reasonable proxy measure. They specifically use winter water consumption, so flower beds are exempt.
Charging for consumption will promote lower water use ranging from large scale on-site treatment as is found at Dockside Green to individual “if it’s yellow, let it mellow” policies. If multiple plants are built progressively, vigorous conservation could lower future costs. For example, BC Hydro is using progressive rates to reduce electricity use, not just building more dams.
The wastewater committee needs to start talking about fair payment, not just abstract costs.
