Fountain Ramming - Tips and Tricks

Fountain Ramming - Tips and Tricks

Basic knowledge of well construction

The ramming well is not just about the presence of groundwater, but also about the accessibility of a productive waterway with a ram. Therefore, it is absolutely necessary to inform yourself about the depth in which water is expected. If there is no well of known depth nearby, the lower water authority can provide information about the groundwater level. Here you can also ask if a well is allowed.

Water deeper than seven meters is not interesting considering the physical limitations of suction pumps. With the Rammspitze one comes only in favorable cases deeper than five meters. Often the limit is reached in three to four meters depth. Therefore, one should also inquire about the soil condition.

In soils of coarse sand the greatest depths can be reached. Hard stone can not be penetrated. Even very fine sand, loam or stony soils are problematic.

Ramming of the Rammspitze

Since complete sets for ramming wells are offered in DIY stores, the impression arises that this is a simple job. The fact is that it is often necessary to hammer the ram filter in different places because the point is poking stones underground.

There is no certainty to encounter water. Another problem is that a water-bearing layer can be pierced unnoticed. If the tip is at a depth of five meters, but the water is three meters deep, it gives the completely wrong impression that there is no water in the place. Therefore one pause of one day should be taken at intervals of one meter to start a suction test with a pump.

The fear of missing a water vein in width is largely unfounded. The water is distributed over a wide area. The danger of being obstructed by a larger rock in the ground is greater than ramming past the water.

Quantity and Quality of Water

Since ramming is possible only to a shallow depth, aboveground water reservoirs are often used Groundwater resources tapped. These are not very rich, the water is not as pure as groundwater. From a ramming well, therefore, only pure service water should be tapped. It is neither suitable for filling pools nor for splashing in the garden.

The ramming filter tends to clog up with silt, therefore the maximum flow rate for these fountains drops rapidly. Also, the wells do not tolerate long rest periods. These waterholes last the longest when water is withdrawn daily via a hand pump. It is not advisable to tap after ramming with an electric pump. Due to the strong suction, the Rammspitze sets very fast.
