Water ingress into tank chambers and dispenser sumps is a problem faced by petrol station operators and owners across the world. It's often thought of as an unavoidable normality. However, dealing with water once it has flooded the chamber (and possibly the tank itself) can be costly. What's more, if water can get into the chamber, leaked fuel can be emitted from the chamber into the environment.
The good news is that we have a solution. Using patented UPP Electrofusion Entry Seals for pipework and UPP Tank Chambers with integrated water-tight lids, all possible leak paths are removed. This ensures water is excluded from the tank chamber and any leaked fuel remains inside.
Where it happens
There are three main locations where water ingress can be a problem:

The hidden costs
Once a chamber is installed and has started taking on water, the only solutions are short-term and reactive and must be repeated many times. For example, water has to be regularly emptied from the flooded tank chamber and, because it is 'contaminated', must be disposed of in a controlled manner. In addition, flood water can cause increased corrosion to tank top furniture items, and water can enter the tank and contaminate the fuel with microorganisms.
UPP Electrofusion Entry Seals electrofuse to the wall of the tank chamber, removing the need for mechanical bolts or threaded pieces or rubber parts. Once fused the seals become one with the chamber wall and cannot become loose or corrode over time.
UPP Tank Chambers are designed using specialist computer software (FEA) to prove they can cope with the tough conditions. They are designed to withstand a 6ft head of water pressure with a safety factor of between 5 and 15. Combined with a Virgin Linear Low Density PE construction material and a nominal wall thickness of 8mm they also have great resistance to hydrocarbons and earth movement.
