The town is encouraging residents to harvest and save rainwater with the use of rain barrels. A rain barrel collects water from the roof when it rains and stores it for use during dry weather to water house plants or outside plantings. Collecting water in a rain barrel is an excellent way to save some of the runoff and take the pressure off our water supply and stormwater management systems. By using the rainwater on your gardens you are helping to replenish your groundwater and benefit our water supply.
