Although Sharon’s town water supply has dropped with the dry weather of the last few weeks, it remains in fine shape, according to Eric Hooper, superintendent of public works. He credited mandatory water restrictions, in place since May 1, with keeping the supply at a healthy level. Many communities wait to implement restrictions, make them voluntary, or do not limit unattended watering to two hours per day, as Sharon does. The rules, which last through Oct. 1, specify that odd-numbered homes may have unattended watering from 6 to 8 p.m. on Mondays and Thursdays, and even-numbered homes from 6 to 8 p.m. on Tuesdays and Fridays. Private wells are exempt unless the well required a variance.
