West Economy Parking Lot Sanitary Sewer

Hartsfield-Jackson Atlanta International Airport

Hartsfield-Jackson Atlanta International Airport West Economy Parking Lot Water Relocation

Client: City of Atlanta | Department of Aviation

Project Location: Atlanta, Georgia

Project Description:

The project involves the sanitary sewer design and route investigation, lift station and storage capacity determination, and sewer flow calculations for transmitting sanitary sewer flows from the proposed airport hotel site just west of the Airport Ground Transportation Center to an existing lift station.

Preliminary work for determining existing system capacity involved obtaining existing flow data from the City of Atlanta DWM and performing a lift station performance test. Sanitary sewer flows from the proposed hotel complex, as well as potential future flows from other sources were calculated and added to the existing system and lift station performance data to determine if storage will be needed.

Based on the investigative preliminary work, it was determined that a mile and a half of sanitary sewer pipe, a portion of which is force main, will be designed to carry flows from the proposed airport hotel site at the West Economy Parking Lot south to an existing lift station located off Riverdale Road adjacent to the airport’s 5th runway.

Though several options were presented to the client which included existing lift station upgrades and upsizing of downstream pipelines, the overall accepted project scope involved the design of a wet well and lift station, 2,000 linear feet of 8-inch force main , 3,500 linear feet of 12-inch gravity sewer, and 100K gallons underground storage.
