The Hopkinton Water-Sewer Department requested Saturday morning that residents on the municipal system turn off all sprinkler systems and refrain from any unnecessary outdoor water use due to a pump motor failure at one of the town’s water wells.

“It is of the utmost importance to ensure water for fire protection and other daily essential needs,” reads an email from Water-Sewer Manager Eric Carty. “The town will be utilizing its auxiliary sources that are safe to drink but may cause some discoloration due to iron in the water.”

Residents were contacted by phone via an emergency message system with the update.
