For Aquarion Customers in Groton, Mystic and Stonington Smarter Watering Begins With You Smarter watering is watering without wasting such an important, irreplaceable resource while also keeping your lawn and garden looking their best. Most importantly, it can be as easy as following Aquarion's mandatory irrigation schedule. Or go a step further...upgrade to a high-efficiency, irrigation system. Either way, you'll reduce what the EPA has identified as one of America's biggest water wasters - lawn and garden overwatering. Meanwhile, you'll make more water available for vital needs throughout your community - like for fire protection and drinking. And that's just plain smart. Questions?
