With Waterloo region's climate projected to be more extreme in the coming decades, officials with the region's water services are already thinking of how to adapt to future changes and challenges. Adapting current infrastructure and future builds to climate change takes time and a lot of planning, said Kaoru Yajima, a senior engineer with the region's water services. It's why that work has already been underway for several years. "We've been seeing changes in the climate for some time. It's not like it just happened today or last year. It's been coming around for some time and we knew that we had to plan," he told CBC Kitchener-Waterloo.
