The Illinois Department of Natural Resources mandates that water conservation measures be undertaken between May 15 and September 15. Glen Ellyn regulations allow odd-numbered street addresses to water lawns on odd-numbered calendar dates, while even-numbered street addresses may water on even-numbered calendar dates. Lawn sprinkling on this odd/even schedule may only be performed from 5-8 a.m. and 7-11 p.m.
Questions about sprinkling should be directed to the Public Works Department at 630-469-6756.
