Sealing of cisterns and basins

For a perfectly watertight cistern or basin

The collection and use of rainwater is ecological and economical. Using clean potable water to wash your car or flush the toilet is nonsense.

In the Flemish region and Brussels-capital, the installation or rehabilitation of a rainwater cistern has become mandatory when building or renovating a home. The Walloon Region does not require the installation of a rainwater cistern, but one in five municipalities requests it when granting a building permit.

At the private level, the collected rainwater can be used for toilets, for watering the garden, for washing your car or for various cleaning operations. With suitable filtration, rainwater can also be made potable.

At the collective level, rainwater can be used as a stock for firefighters. The cisterns sealed by Hydrotec at the Napoleon Museum in Waterloo or under the Golden Fleece complex in Brussels are of this type.
