One of the main global targets to solve along this century will be to ensure the availability and quality of water.
Accordingly, the harmonization of water supply infrastructures with the environment, besides the adequate security measures, will be increasingly demanded by the society.
Nevertheless, water is also one of the main aggressive agents in the construction industry. The presence of water in building and civil works is a causal factor of degradation, both of structural elements and outdoor elements.
It is obvious that water supply infrastructures must be protected against degradation, avoiding losses and pollution of water by construction elements.
