Rockport is among the many towns nationwide offering discounted rain barrels to their residents to help residents manage their water supplies. The Town strongly encourages the use of rain barrels as part of its town-wide water conservation initiative. Collected rain water helps during times of drought and aids in controlling runoff during heavy rains. It can be used for watering gardens, lawns, washing cars, and many other non-potable purposes. Using rainwater reduces overall water demand. This is especially valuable in times of drought and restrictions due to contamination. When rain arrives in torrents, diverting some into rain barrels helps slow down runoff and limits erosion. And because rainwater isn’t chlorinated, it’s great for plants and lawns.
