Stormwater Management (SWM) aims to protect the community and the environment from stormwater runoff, created by rain and snow melt events, by controlling stormwater quality and quantity. Before infrastructure development, water would be absorbed into the ground after it rains.
After infrastructure development, hard surfaces like roofs, driveways, roads, and parking lots prevent absorption, increasing the amount of water collected by storm drains. Before stormwater reaches the storm system, stormwater flows over these hard surfaces, accumulating debris, chemicals, and other pollutants that can have a negative impact on surrounding aquatic ecosystems. Once the stormwater reaches the storm sewer system, water flows through a large, complex network of pipes and waterways until its eventual release back into the natural environment.
The Town aims to use Low Impact Development (a form of stormwater management) to manage stormwater in Newmarket. View the links below to learn more about Stormwater Management and Low Impact Development and Green Infrastructure in Newmarket.
