For example, an individual who submits a request for a well wipe a refusal if he is already connected to the public water network. “Similarly, if it is on the outskirts of a village, that it can be connected to the public network at a connection cost less than 2 times the cost of the borehole.” Recreational use – to fill a swimming pool or water the garden, has also become a reason for refusal. But even professional use can receive a “no”, in certain circumstances. “For example, the farmer who already irrigates with two wells, and comes to request a 3rd well, while two existing wells is not exploited at 100 % of their capacity,” said the SPW.
2. The drilling, by an approved borter
Do not be impressed by the term borehole, it is a small diameter, 18 cm. At what depth? “The objective is to reach the water saturated in water,” says the hydrogeologist. It depends on the level of the tablecloth, and also on the hydraulic network, such as the presence of the Meuse.
For example, in Dinant, when we see the rock flush, the tablecloth is often 60, 70 meters deep. “Note that the water intake must have an area of 10 meters without activity, around the catchment. It must also have a waterproof visit chamber, enhanced with respect to the ground level” to avoid the infiltration of surface water, closed by a closed access hatch “.

3. Declaration of the drilling site
The driller, before the drilling site, must declare the start of work to the administration (Directorate of groundwater). It establishes a drilling ratio intended for the applicant including geological cut and well equipment (depth, height of the perforated tubing, etc.). The applicant must send them after the administration, within two months maximum following the end of the drilling.
Do we have to pay to use the well?
“A volumetric counter is compulsory on all water intakes”, except that which exclusively feeds a household for domestic uses, says Bougard. “For water intakes whose levy is greater than 3,000 m3/year, the direct debit contribution is fixed by consumption tranche.” It is the direction of economic instruments and financial tools which calculates and controls the taxes linked to the use of the water provided by the water code.
There is no legal obligation for the individual with regard to the qualitative monitoring of the water taken. In case of doubt about the quality of the water, it is advisable to have analyzes carried out by an approved laboratory and to follow the recommendations of the competent authorities. If filters are used, the region warns the choice of filters adapted to the nature of the pollution and to maintain them correctly.

What to know about the wells in Wallonia
Authorized Foreurs
No question of launching yourself by renting a carroter, the borehole must be made by an approved borehole for drilling for water intake. The list is found on the Wallonia environment portal.
DPA and DPC, who does what?
The individual or the farmer who wants a request for a license via the ad hoc forms (available on the Wallonia environment portal). It is the municipality which receives the request and has it followed up on the DPA (Department of License and Authorizations), which requests, before establishing its summary report, the opinion of the bodies concerned. The report is then communicated to the municipal administration which grants or refuses the permit on this basis. The DPC (Department of Police and Controls) is responsible for going to the field to inspect whether the water intake complies with the planned conditions.
Should we declare an existing well?
Yes, yes, even the old wells (traditional wells). They are different: masonry in birques, where the bored well is in full tubing on a certain depth, to get rid of the arrival of surface water (and its risk of pollution), and in depth of the perforated tubing. These wells are also not taxed below a 3000 m3 sample per year.
