If possible, only clean the well mechanically


Cleaning a well depends on the type of well. A drilled well is usually easier to clean than a piling or hammering well. The effort depends on the type of contamination, which may be mechanical or biochemical. In addition to the well pipe or inner shaft itself often the surrounding filter layer must be cleaned with.

Dispose of chemicals only in wastewater

The very first rule when cleaning a well is the renunciation of chemical cleaning agents of all kinds. Most soiling are mechanically solvable. If auxiliaries such as javelwasser or hydrogen peroxide, also for disinfection reasons, are used, the discharge into wastewater outlets must be guaranteed.

If the conveying force of the well wears off, several causes are conceivable. Normally, the first noticeable production waste is ten to twenty percent. The regular and early cleaning reduces the workload for individual cleaning. Already with a decrease in production from thirty percent, the pollution grows exponentially.

High pressure and filter gravel

In the case of a hammering or driving well, the pollution depends on the conveying speed and the volume of water. The faster the material is conveyed, the faster the material settles in the filter openings. Therefore, the life of a well is usually only a few years.

The mechanical power of a high-pressure cleaner can "blow" the sands that have been smeared out of the filter slots. However, this type of cleaning only temporarily protects against the clogging of the well, as the sands are re-flooded with every extraction. For a thorough sanding of the well, the filter layer of gravel or gravel poured around the well pipe must also be cleaned.

Oozing and cleaning acids

If you wash a well for cleaning, you should use mechanical methods if possible. Brushes, high-pressure steam cleaners and steam cleaners also remove biochemical deposits, such as in a well that has been sealed up. The iron and manganese buildup crumble in the early stages.

For stubborn dirt, for example, by organic materials such as algae vinegar cleaner can be mixed in small doses of the rinse water. With strong lime deposits citric acid or amidosulfinic acid comes into consideration, which are very harmful to the environment. They may only be used if they can be supplied to the wastewater. In addition, there is a high risk of corrosion in metal well pipes.

Javel water and hydrogen peroxide

Only professional fountain cleaners are allowed to use hydrogen peroxide and javel water, potassium or sodium hypochlorite for very stubborn deposits. Water with added acid must not hit Javelwasser, otherwise life-threatening chlorine gas will develop. The life-threatening risk is similar to that of the medieval fountain cleaners, who were often poisoned by carbonic acid.

When silting up, silting up or using cleaning additives that are harmful to the environment and to health, the rinsing water and / or the sludge particles can be pumped down into the sewage system with a sewage pump.

Tips & Tricks

If you can not clean a multi-year old waterfall well with effective results, disassembly can sometimes be done by pulling it out. Clean the pipes, if still in good condition, and drive a new well into the ground.
