If the design objective is to meet and provide peak flow control for storm events, it is necessary to plan beyond the 1:100-year peak flow, and instead plan for the new norm of a 1:1000-year flood event. Planning for the appropriate peak flow is crucial to building climate resilience and meeting the demand over the full lifecycle of the infrastructure. If an inadequate peak flow formula is used it could result in significant additional costs to the City if it has to repair or tear up failing infrastructure to rebuild and increase capacity before it has reached its end-life. “Even a 1000-year return period has a 5% risk of being equalled or exceeded in a 50-year period.”
The extremes of climate change will affect the operation of critical infrastructure such as water and wastewater treatment plants, sewers, the electrical grid, public transport and roads that are sensitive to temperature and weather thresholds. Beyond these thresholds, infrastructure may have reduced capacity or may not function at all.

Greater Sudbury is the “City of Lakes” and many people living on waterfront properties are dedicated to protecting the water quality around their homes. Recently, several lakes in the Sudbury area have developed blue/green algae blooms affecting drinking water and closing beaches.
Some of the causes of algae blooms are faulty septic systems, storm water run-off and increased levels of phosphorus and nitrogen.
