Aquarion Water Company on Wednesday announced the start of the 2021 mandatory sprinkler irrigation schedule for customers in Darien and some other communities. The utility again is banning lawn watering on specified days to conserve water supplies by reducing overwatering of lawns and gardens. Aquarion has published a schedule providing for a maximum of two days of watering per week. Customers may continue using drip irrigation, soaker hoses and hand-held watering at any time. — an announcement from Aquarion Water Co.
