Water

Within the context of environmental protection, it is imperative to avoid wasting water, especially when its supply is uncertain. It also is impera tive to recover and recycle the water used by the activity. Best practices include saving water by using it more than once and collecting rainwater in tanks thanks to gutters.

As it is not drinking water but “industrial” water, it needs to be sieved and clarified. In these operations, water is filtered with a membrane, or with sand or carbon filters.
