![Rainwater tank][1] [1]: http://i.imgur.com/PIWOmsQ.jpg This photo belongs to the series of invisible infrastructure, however, very necessary to the coastal cities of the Mediterranean. It is a rainwater tank. Mediterranean cities have the problem of rain in a very short space of time drops a lot of rain they collapse drainage systems and water pipes busting and inundates the streets cause damage and accidents in short period of time. For this reason has been built the first tank of rainwater, which is capable of contain up to 13 million cubic meters of water. When it will rain heavily and sewage are very full, they are diverted to this deposit and they are filled during the storm and this deposit is emptied as sewers carry little water. Due to the high cost, about 8 million euros only been able to build one in the conflict zone (the coincidence of two important avenues of water at a common point) in the city.
