A well in my garden

According to Article 641 of the Civil Code, "Every owner has the right to use and dispose of rainwater that falls on its fund". As the price of water continues to rise, more and more of us want to take advantage of this right. But in recent years, the legislation has hardened and it is no longer as easy as before to freely enjoy the water flowing to the bottom of his garden. That's why, HandymanDuDimanche gives you some tips on wells and boreholes.

Legislation framing wells

Before giving the first shot, you will have to perform some administrative procedures. For a well for domestic use, you must make a declaration of work at the town hall. For a well more than ten meters deep, it is to the DRIRE, the Regional Directorate for Research and the Environment, that you will send your declaration. Finally, if you want to drink the water from your well, you will have to refer to the departmental direction of health and social affairs, the DDASS. Once the well is completed, you will be required to make a declaration of completion with acknowledgment of receipt. Once you have completed all the steps, you are not immune to a control visit. If the latter is inconclusive, then you will have to redo some standardization work, or even close your water supply. Be careful, if by making a well in your plot you reduce the flow of that of your neighbors, the law allows them to claim compensation.

Well or bore?

Wells and boreholes are distinguished according to their depth and diameter. Wells, whether round or square, have a wide opening and go up to about twenty meters. They are content to collect surface water: rainwater and sometimes groundwater. Their flow is very random because it varies according to the seasons and climatic hazards. On the other hand, the boreholes are narrow but much deeper and generally offer more flow. For regular domestic consumption, it is better to opt for a well where a well would be enough to water your garden and wash your car.


Before digging, you will need to define the proper location of the well or borehole. Two solutions are available to you. The first is to call on a dowser who will examine your garden with his wand. The second, less traditional but more Cartesian, is to consult an expert in hydrogeology. You can also observe the plan of occupation of grounds, thus of your ground, which you will certainly find in the town hall, but nothing guarantees you that it is complete or reliable. With a little experience and a lot of determination, it is quite possible to make your own well, manually or mechanically. For drilling, it is better to call a professional, counting from fifty to one hundred euros per meter of depth, without forgetting the purchase of the pump.

Use the water from your well

Unless you reserve it for the garden only, the water in your well or well is subject to strict regulation. If you want to use it for your washing machine, your dishwasher or to feed your toilet, it will be necessary to set up a circuit of secondary water quite distinct from that of the mains water. Finally, to drink or wash with water well, it is imperative to have it tested by an accredited laboratory, and several times a year. You will also have to declare it to the prefecture which will certainly install you a meter in order to apply the sanitation tax on the water that you will reject to the sewer.

Economical, certainly, but not always ecological, wells and boreholes sometimes deplete the water table and are likely to dry up the surrounding sources. We must not waste this water which, even if it is free, remains precious.
