Crossland Heavy teams had to demo out the existing aeration basin which sat in the location where the new final clarifier would be constructed. During the construction of the screw pump station, Crossland Heavy’s teams had to setup bypass pumps to divert all of the flow entering the plant. We also had to sequence our new pumps and piping in the RAS/WAS building to install the new pipe/pumps, all while the plant was operational through the use of their existing equipment.
One challenge in the RAS/WAS building was that all the work took place in a basement with very minimal access. We had to disassemble pumps to get them into the room and maneuver them into place. We also had to be creative when ordering pipe so that we didn’t receive any pieces that were too large to fit through the small access hatch. Every move made in the basement had to be pre-meditated and meticulously planned in order for proper and safe placement around existing piping and pumps.
