Hanover officials are asking local residents to conserve water until electricity is restored to the borough's water filtration plant.
An ice storm earlier this week left the plant without power for days, and the back-up generator has also failed at times, said borough Manager Barb Krebs.
At about 9:30 p.m. Thursday the generator went down and borough officials alerted water customers to conserve water. Though the generator was functional by 11 p.m., it took a while for the pumps to properly operate, she said.
"We want to stress to the public we're not at full capacity. We will continue to ask the public to conserve water because there's still no electricity to the water filtration plant," Krebs said.
Met-Ed has deployed several crews to work on repairs at the plant, she said.
"They have Met-Ed crews from all over the country working on this. They're working as fast as they can," Krebs said.
A Met-Ed spokesman could not immediately be reached.
