Deputy Director of Watershed Management Maria Hayes gave a lengthy presentation about fixing DeKalb County’s water system to the Public Works and Infrastructure committee in a special called meeting on May 22.

The comprehensive presentation closed with a preview of high-level spending options the county can use to improve its water system in order to improve service reliability. Replacing all pipes that will be 70 years old by 2050 will cost the county roughly $4.4 billion.

Noting recent main breaks and service failures in the McLendon Drive area, Hayes began the presentation with the history of the water system beginning with the first pipes being installed in 1909.
