 And that means outdoor sprinkler and irrigation systems in Danvers are limited to just a few days a week. And that includes today, Tuesdays and Saturdays, only from seven o'clock at night to 8 a.m. the next day. Using watering cans and handheld hoses are still okay. That's allowed at any time. Danvers officials say they will post any restriction changes on their town website and social media.
