in Bordeaux, the boom in water reservoirs accessible to all

Water reservoirs are increasingly popular with the inhabitants of Bordeaux (Gironde). This is the case of Nicole Etienne who uses a large tank. Its operation is simple: rainwater falls on the roof and slides into a gutter to reach the tank with a capacity of 300 liters. An anti-drought method that also convinced her husband: “It’s free water from the sky and it’s good for the planet so I’m not going to deprive myself of it”.

A budget of 80 to 259 euros

In a garden center, tanks are sold between 80 and 259 euros. Faced with these low prices, customers are convinced. So much so that in three years, the offer has tripled and installation has been simplified. “Today, with a small kit, we drill a gutter so people are doing it more and more by themselves“, explains a salesman. Several municipalities have set up financial aid for the purchase of a reservoir.
