The electrical failure of a water pump Tuesday morning caused low water pressure and discolored water in Branford, East Haven and eastern New Haven, according to the South Central Connecticut Regional Water Authority.
The pumps supply water to the Lake Saltonstall Water Treatment Plant. As of 4 p.m. Wednesday, the water treatment plant had been stabilized and the discoloration was clearing, according to a release from water authority.
Water authority crews worked throughout the day Tuesday on "operational changes" to keep the water supply coming and plan on working overnight to resolve the water pressure issues.
Crews reversed the water flow so that water could be supplied from other sources, stirring up sediment in the pipe that is leading to tinted water, according to a news release from the water authority.
The water authority advised residents to drink bottled water if they notice an issue or to put the water in a pitcher and let the sediment fall to the bottom so they could drink the clear water on top.
The water authority also recommended holding off on laundry, especially light-colored clothes, until the problem was resolved.
