Ridgeway said that fuse allows the town’s water tanks to “talk” to each other. When the main tank runs low on water, it “asks” the backup tank to send it more. With the fuse out of commission, the main tank ran low and could not be refilled. Customers began to notice the problem early Friday morning, nearly 10 hours after the truck carrying the oversized load had passed through town.
South Carolina Electric & Gas (SCE&G), which had to trim a number of trees and move power poles in order for the load to pass through on its way to Jenkinsville, replaced the fuse Friday afternoon. Meanwhile, a bypass line had been opened up to allow water to flow into the empty tank. That line contained sediment, causing customers to see a discoloration in their water. Because of the drop in water pressure, Ridgeway was required to send test samples of the water to the S.C. Department of Environmental Control (DHEC), which were submitted Monday morning. Ridgeway said there is typically a 24-hour turnaround time for such samples, which must be cleared by DHEC before the boil advisory can be lifted.
