KAWC Using trenchless technology to upgrade water main

Project represents first time trenchless method is used by company for waterline replacement

Lexington, Ky. (June 27, 2016) – Kentucky American Water is wrapping up the final phase of an extensive water main
replacement project along the North Limestone Street area in downtown Lexington using unique technology that is less
disruptive and more cost-effective.

The $230,000 project involves replacing 1,200 feet of 10-inch-diameter and 12-inch-diameter cast iron pipe. Typically
water main replacements involve significant excavation – digging through pavement and concrete – and because of the
excavation, can be disruptive for traffic and extend the time needed for restoration after the pipe replacement is complete.

Trenchless technology, however, involves digging few access pits, cleaning the existing pipe, and slip lining an existing
pipe with a new pipe made of cured-in-place pipe. The technology has been used in recent years for sewer line
replacement, but is newer to the drinking water industry.

The project is currently underway, with plans for completion in mid-to-late July.
