WAPA will use the downtime to compensate water pressure

ST. THOMAS - At least half of all V.I. Water and Power Authority customers can expect reduced water pressure for up to 16 hours a day while technicians diagnose and repair a steam turbine and a leak in a boiler.

When the authority's Unit 11 steam turbine shut itself off Thursday, technicians found a water leak in Unit 21, a waste-leak recovery boiler that authority spokeswoman Cassandra Dunn said later caused officials to enact the temporary shut-down.

Even in the affected areas where there is water pressure, she said, it would not be enough to take a shower that would be enjoyable.

Water with regular pressure will be available from 5 a.m. to 9 a.m. and from 5 p.m. to 9 p.m. until the authority completes the repairs, Dunn said.

"There's someone that will arrive later today or in the morning, and they will be making the assessment with the bearings and the loader on the steam turbine," Dunn said on Friday.

A team of about 40 technicians, including welders, plant mechanics, instrument technicians and electrical and mechanical engineers are on call 24 hours a day to make the repairs, Dunn said.

"When they indicate they'll be working 24 hours, it indicates it will be repairs that require intense effort," she said. "Today, the decision was made to try to conserve the water that was available because we would no longer be able to produce."

"They're still troubleshooting what happened to the steam turbine," she said. "Obviously they had a problem with the steam that we use to make water."
