Pickering 2 MM gallon Clearwell

When this two million gallon, ¾ below grade tank was emptied, it was discovered that numerous structural repairs were necessary. This resulted in excavation around the below grade portion of the tank’s exterior to access those areas in need of repair. While this excavation was in process, it was decided to also completely strip the exterior and repaint it. The product that was chosen for this application was Induron’s Permaclean 100, a 100% solids ceramic filled epoxy. It was chosen because it could be applied at a high build in a single coat (< 25 mils). It could also be applied in cold weather (temps down to 30’F), and it would allow the above grade portions of the shell to be top-coated with the same intermediate and finish coats as were to be applied on the roof. Also, the ceramic beads would provide the abrasion resistance necessary for the backfilling operation as well as prevention of the previous corrosion problems. Finally, this is the product that Aqua Pennsylvania uses for protecting the interior of their tanks. It carries NSF certification in applications up to 50 mils and it was to be used as the finish coat on the interior of this tank as well.

This emergency repair and repainting operation took place over the snowiest winter Valley Forge has seen in 50 years. The project was completed by the June 1st deadline and the tank was successfully placed in service with no water quality issues whatsoever.
