The way our two tiers work is one of the unusual ones—I think there are only a couple left in Ontario—where the region owns all the water treatment plants, pumping stations, storage, and major trunk mains that transport water across municipal lines. From the first valve off those larger lines, it becomes a municipal responsibility, so we have our own water mains and we bill. The meters are ours, so we bill the citizen, and the region bills us through its larger systems.
That's the reason the region contributed to our corrosion control plan and to the decision to help fund private-side replacements. For the Welland plant alone, if I recall the numbers correctly, it was almost $2 million to upgrade the plant to provide corrosion control, and then a $200,000 annual expense for the chemicals and the maintenance of those systems.
