Palmyra Borough Sinkhole

A major break in an 8-inch water main caused a geyser, which flowed for nearly six hours before the main was shut down. A large sinkhole developed as a result of the excess water, causing a third of a major traffic intersection to collapse and, consequently, to be closed. In addition the underground utilities in the area were a major safety concern. The Borough Manager and the Pennsylvania American Water Company needed to resolve this issue as quickly as possible to ensure safety and convenience for the local travelers.

RETTEW was on site the next day to assess the situation. RETTEW advised the Borough to have the excavating contractor mobilize as quickly as possible and to call the local gas company to stabilize and later move the underground gas line undermined by the sinkhole. The sinkhole was remediated on a rapid-response schedule under RETTEW’s constant guidance. The intersection was repaved and reopened and is, once again, a safe and convenient route for travelers.
