- Climate Ready Infrastructure and Strategic Sites Protocol : Method to Assess Vulnerability to Extreme Weather Municipalities in the Great Lakes Region are already experiencing the effects of climate change – from flooding, to extreme temperatures, to winter storms, to high winds, Great Lakes cities are at different stages of preparedness for extreme weather associated with climate change.
Through a collaboration with AECOM, the City of Gary and University of Michigan’s Great Lakes Integrated Science and Assessment office, the Cities Initiative has developed the Climate Ready Infrastructure and Strategic Sites Protocol (CRISSP), which relies on available data and municipal staff’s own knowledge of their facilities and infrastructure to assess their assets’ vulnerability to extreme weather in a way that is both relatively quick and low-cost.
A key aspect of the CRISSP is a helpful, easy to use Risk Matrix tool that takes users through a series of critical questions to assess the vulnerability of municipal facilities, sites or infrastructure.
- Water services facing climate change: for an integrated approch Climate change can manifest itself in different forms and impact water treatment plants in a number of ways. Intense intervals of precipitation can be followed by prolonged periods of drought. The capture installations are therefore subjected to severe tests whereas the sediment supply can interfere with their operation. The characteristics of the raw water can also change rapidly, thus challenging the performance of the processes. The City of Repentigny has built and rehabilitated many of these infrastructures over the years to increase their robustness against such events. Research has been conducted to adapt the processes to meet current standards at all times. Finally, efforts have been made to fully recover biogas and biosolids from wastewater treatment to help reduce greenhouse gas emissions.
- Fires, Floods and Other Threats to Water: Resilient Drinking Water Treatment Approaches for Climate Change Adaptation International consensus has suggested that severe, extreme events such as wildfires and floods have the potential to be catastrophic for the provision of safe drinking water because they can cause increasingly variable and/or deteriorated source quality, thereby challenging in-plant treatment technologies beyond their design and operational response capacities, to the point of decreased production capacity, boil water advisories, and even severe and costly service disruptions. Thus, it is commonly believed that severe wildfire threatens drinking water treatability because of insufficient treatment technology capacity or “resilience.” Based on experience in Canada and internationally, the major changes in source water quality that can be expected in drinking water supplies will be presented and the best available technology approaches for responding to associated drinking water treatability challenges will discussed.
