There are several ways to obtain a waterwell. Many providers offer a ‘sprayed source’ or ‘bailer drilling’. This is a relatively inexpensive way that usually involves a local contractor. Manually or using a slurry tank, a hole is sprayed into the ground (maximum 10 to 15 meters) and then a filter tube is quickly inserted before the hole clogs up again. These sources can last for a number of years, but can also clog up after a year. Also, the water is usually heavily ferrous. In situations where the requirements on quality and capacity of the source are low, this is a good solution.
Flush drilling
Remon has quickly abandoned pulse drilling and only uses the professional flushing and suction drilling methods. At flush drilling, the drilling mud (working water) is pressured through the rotary drill pipes. With the help of the drill head, the water flushes the soil loose. The soil that comes loose is pumped up and collected in the flushing tank (Remon no longer works with flushing ponds). When the driller is at depth, the drilling tubes are removed from the drilling hole. Due to the created overpressure, the walls of the drill hole cannot collapse. Subsequently, the filter is built in and the source is filled according to BRL guidelines.
Suction drilling
At the suction drilling method, the drilling mud with the loosened soil is sucked up through the drilling tubes, contrary to flush drilling. This soil is pumped back into the flushing tank which is connected to the drilling hole. This method is often used for larger diameters. This method also allows accurate sampling, which leads to better data from the substrate.
