R2T provided Engineering Services to the City of Atlanta (COA) for the design and procurement of the Chattahoochee and Hemphill WTP Improvement projects. Both water treatment plants receive water from the Chattahoochee River and are designed and permitted to treat a combined 201 million gallons per day to serve the bulk of Atlanta’s demand including downtown Atlanta and the Hartsfield-Jackson Atlanta International Airport. The Chattahoochee and Hemphill WTP projects address several of the Department of Watershed Management’s Strategic Priority Areas such as Compliance, Reliability, Efficiency, Safety and Security while providing a clean, safe and sustainable water supply.
R2T provided architectural, structural, process mechanical, civil, electrical and instrumentation design services for five discreet design-bid-build packages. Several immediate and capital needs at both plants were identified through facility assessments and other COA master planning projects performed by R2T. The assessments identified projects that address improvements to the residuals handling facilities, replacement of critical equipment, and Chemical feed improvements.
R2T provided construction cost estimates at each progressive deliverable and identified solutions to help value. During the design phase of the project and in preparation for solicitation, R2T led the permitting effort associated with each bid package and provided notification where required. Permits or notifications were prepared and submitted in compliance with the City of Atlanta and county and state regulators such as the Georgia Environmental Protection Division.
