Climate change is emerging as a driver for rainwater harvesting
What does this statement of provincial policy mean for architects, engineers and contractors in British Columbia? It means that rainwater harvesting will emerge as a substitute source of water supply, particularly for new commercial and institutional buildings. An example of what this means in practice is the Discovery Green building project in Burnaby; rainwater harvesting will contribute to a reported 72% reduction in reliance on the regional water system.
“Climate change is emerging as a driver for rainwater harvesting in the urban regions of British Columbia, partly because of the need to mitigate risk.In Metro Vancouver, for example, a declining snowpack means less water is available to replenish lake storage reservoirs during the high-demand summer season. The need to offset this loss provides an incentive to capture rain where it falls on roof surfaces,” explains Kim Stephens, Program Coordinator for the Water Sustainability Action Plan for British Columbia.
