At the price of the cubic meter, using drinking water to water the garden, clean a terrace or wash a vehicle is nonsense … To save a good as precious as water, Boutté offers an alternative to boreholes classic. A sustainable and economical solution.

Some regions of our planet have a lot of fresh water while others lack it. To overcome this problem, Spanish researchers have developed a strange solution: a pocket allowing water to be transported easily and efficiently by sea. Discover it thanks to the Euronews channel, in this new episode of Futuris.

To enjoy a water reserve for the garden it is always possible to install one or more rainwater collectors. However, these water reserves remain limited by their volume. To take advantage of free and abundant water, Boutté offers the “tap a well” concept. The latter consists of a pierced striking point, extensions, sleeves and a striking head. Galvanized steel elements that allow both to drill a well and serve as a conduit. A design that eliminates the need for hydraulic equipment or tires traditionally used for drilling.

Determine the presence of water in your garden

Before starting the implementation, it is necessary to locate the presence of a water table or a water vein in your land, then determine its characteristics (drilling depth, debit…). To achieve this, several solutions are available to you:

  • contact a hydrologist via a geology office;
  • call on a dowser: traditional and risky method, it is advisable to check with your neighborhood to find the right person;
  • consult the base of national data BSS-EAU. The latter provides information on water points and associated groundwater data. It’s up to you to interpret the information …

A muscular implementation

Once the water table or vein is located, you can install the striking point. With a length of 1.21 meters and equipped with a hexagonal point, this element sinks in with mass in the ground up to the water table or the water vein. To reach the desired depth, just screw on one or more extensions using sleeves. A simple operation on paper but which proves physical. To carry out this operation, it is necessary to:

  • regularly check the plumbness of the striking point;
  • Tap moderately with a hammer or ram to avoid any risk of breaking the striking head.

A pump according to water needs

To use the water captured by the striking point, it is necessary to connect a surface pump at the outlet. via an anti-sand filter and a non-return valve. Choose the latter according to:

  • your daily consumption (expressed in m3 or l / min);
  • the total manometric head (HMT). This corresponds to the sum of the height difference, the pressure useful and pressure drop.

A mandatory declaration to be filed at the town hall

Water being a precious commodity, out of the question to do anything and anyhow. Whatever the depth of the well, before taking groundwater, it is imperative to establish a town hall a work declaration one month before the start of the work and to attach a extract from the land register (failing that a 1/25000 map) locating the sampling point. Note that the use of water from a well for human purposes must be analyzed by an accredited laboratory. The results must then be sent with the initial dossier.

As’rainwater, water from a well can be used in the house to supply a washing machine, toilets … provided that this equipment is connected to a supply network separate from that of the city water. An obligation to avoid any risk of contamination of drinking water.

What you must remember

  • The installation of this type of drilling is carried out in soft ground and far from the house.
  • The water withdrawn is intended for exclusively domestic use.
  • This solution is limited to a depth of seven meters.
  • Beyond 10 meters in depth, it is compulsory to declare the drilling to the regional environment directorate (DREAL).
