What if the power fails? Does the water supply system have a backup electricity generation system?
In the unlikely event that a power failure occurs, the city’s water supply system relies on two separate power supplies to all facilities to ensure continuous operation if a local failure occurs in the primary power supply. The water supply system is a fully integrated network that provides flexibility in dealing with local power outages. For example, if a power failure occurred at one of the city’s water filtration plants, system adjustments would be made and the other plants would make up the shortfall. In addition, the water supply system has a storage capacity of up to 24 hours of water in the extremely unlikely event of a widespread power outage. Power failures are extremely unlikely because Ontario Hydro and Toronto Hydro, with the city’s cooperation, have been working to ensure that power systems will be unaffected by the date change. In fact, on March 6th, Ontario Hydro moved its clocks forward to simulate the date change for its high voltage transmission system in central and
