Project Overview

This extensive Water Supply Program will provide the City of Atlanta with a reliable supply of drinking water for the next 100 years and increase the emergency raw water reserve from three days to more than 30 days. Work included converting an existing 400-foot-deep rock quarry to a 2.4-billion-gallon water facility while digging, boring and installing a 5-mile, 10-foot diameter tunnel to connect the quarry facility to the Hemphill and Chattahoochee Water Treatment Plants. Two new pump stations support the system and feature eight vertical turbine pumps and three submersible turbine pumps.

The CM at-Risk delivery method and the extensive preconstruction phase resulted in a year of schedule savings and successful community outreach, public procurement, and value engineering and constructability analysis.
