Hanahan Water Treatment Plant
Hanahan, SC, United States
The 100 year old Hanahan Water Treatment Plant is undergoing some major modernizations to ensure continuous clean drinking water to the local 400,000 area residents of Charleston, SC and further expand the capacity to treat over 100 million gallons of water per day.
PERI has provided formwork and shoring solutions to the concrete contractor Donley’s for the construction of the Sedimentation Basins 9& 11 and the Settled Water Effluent Flume.

Location
The Project
Impressions from the project process
Crews pouring 21 foot tall concrete wall using TRIO 330 panels, resulting in a neat tie pattern and clean concrete finish
Crews pouring the wall
TRIO wall formwork ready to be stripped from new concrete wall
QUATTRO columns being used inside the settling basin - these concrete formwork columns allow up to 24 inch squares with no ties
Preassembled towers are flown into place before the decking and reinforcement for the walkway is installed
Fully decked and ready for rebar - the walkway was designed with full sheets of plywood to make the assembly simple and provide ample space
PERI UP Shoring Towers with MULTIFLEX are used to pour the walkways over the columns and perimeter walls
The walkway falsework was designed to allow the unbraced MULTIPROPS to be installed just before the pour, keeping the work area open and uncongested
The Slab Stopend Bar was used to form the elevated slab edge when no outside walkway was necessary. This keeps the area secure with minimal effort to install and plumb the slab edge.
The next phase of the project will include tearing down the basins from 1904 and replacing them with new ones
