The current raw water supply system for the City of Atlanta dates back to 1893, the newest construction being done in 1975. The City acquired the Bellwood Quarry to create a new 2.4 billion gallon water storage facility that would be able to provide the City with 30-days of backup water. To connect the Hemphill WTP, Chattahoochee WTP, and the Chattahoochee River intake to the new water storage facility, Atkinson is constructing a 5-mile long, 10-foot diameter tunnel.

To meet the project needs and requirements, Maxon built an electric rail-mounted Maxcrete. Maxon also converted a diesel trailer-mounted Putzmeister BSA120 into an electric rail-mounted BSA120.

Agitator cars are filled with concrete and transported to the feed conveyor on the Maxon Maxcrete.

Feed conveyor loads the Maxon Maxcrete body. The body is a remix surge hopper with the ability to hold and re-temper concrete longer than the agitator cars and match the speeds of the Putzmeister BSA120 before placing to the forms.
