Newton WaterWorks will flush fire hydrants north of First Avenue and Bittersweet Subdivision beginning Friday from 10 p.m. until 6 a.m. Saturday.

Fire hydrants for all customers south of First Avenue then will be flushed beginning at 10 p.m. Saturday and continuing until 6 a.m. Sunday.

Fire hydrants are flushed several times a year to clear the water mains of internal corrosion and residue that builds up naturally in the water mains.While no interruption in water service will occur as a result of the work, Newton WaterWorks officials advise customers that they may experience some drop in water pressure or some discoloration of their water.
