This installation was performed for a pipeline company that transports fuel over large distances. At one of the fuel depots, there will always be small spills and leaks that are very difficult to control. Submersible pumps are installed within and around the perimeter of the site to ensure a polluted plume does develop and enter the aquifer close by. Constant pumping and water quality analysis takes places. When pumps go down, they have to be removed and replaced immediately in a safe and efficient manner. PVC was originally used but the inefficiency and safety of rigid column was an issue while the speed with which pumps were replaced was also a problem. A preventative maintenance program is in place at a similar site and the customer wants to replicate the success of this approach to control the groundwater.
