Drinking water is running out in steinfeld

Actually, the households in the stadelhofen district of steinfeld have no reason to be dissatisfied with their water supply. "The quality is very good, we have never had any problems so far", emphasizes mayor ludwig gohl. Since its own deep well was drilled in the 1960s, it has been supplying people with the best drinking water. Previously, there were domestic wells and, of course, the wiesent spring. But now the local network is becoming weaker and weaker – pipe bursts are repeatedly causing the precious water to become scarce.
Water keeper martin barth therefore checks the high reservoir of the plant every day. He can tell from the glass blocks that have been grouted into the building what the supply situation is like. "When brewing takes place, consumption is much higher and the water level is much lower. If there is no brewing and the level drops, it is an alarm signal", says the experienced expert. Because then the probability is high that a leak has occurred somewhere in the local network. And then the water becomes scarce.

Payer changed

Mayor gohl gives some figures. "Per year the water supply steinfeld demands about 28 000 cubic meters of water, about 85 per day. The average consumption is 25 000, which is a good 80 cubic meters per day". This shows that when pipes burst, drinking water can quickly become scarce, because five to ten cubic meters can run out quickly. In order to get correct figures, the payers have already been changed in the past years. "They can also be a problem. Elsewhere, therefore, one has even sold more water than according to the payers of the O have been drawn". There the payer was replaced "now it fits", says gohl. But back to steinfeld. Twice this year we had to cope with pipe bursts, both on house lines. Once in spring, then again six weeks ago. Both times it took a few days to locate the leaks, the water flowed out and was no longer sufficient. In both cases, water had to be supplied by tankers of a private company from the local network of the long-distance water supply (O) located downstream. "The first time it was about 60 cubic meters, the second time about 75", says martin barth. This was enough to get by until the breaks were located and repaired. In one case, an iron pile hit the line during construction work, in the other case the cause is unknown. But of course, such rescue operations should not be permanent. That is why the municipality of stadelhofen is thinking about ways to remedy the situation. "We quickly notice breaks in the main line, but it's difficult to locate house lines, according to the head of the community. At the moment, the water from the deep well is first pumped into the local network, and the overflow flows into the elevated tank. This sequence could be reversed. However, some fear that the water pressure in steinfeld will then drop. However, the current eight to ten bar is not considered too high, nor is it the cause of the pipe bursts.

Ring line as a remedy

The remedy was a ring line directly from the pump to the high level tank and from there to the local network. 1.2 kilometers of pipeline had to be built, at a cost of 150 euros per meter. At present, the demand possibilities are being tested. It is uncertain, however, whether such a line would solve the problem. "At least we had more clarity", says ludwig gohl. In his opinion, another cause of the water losses could also be the overflow of the elevated reservoir. "If something runs away at night, no one notices. On average, 3500 to 4500 cubic meters of water are lost per year, which could not be traced. Only a part of it – about 1000 cubic meters – could be assigned to the water withdrawal by fire department operations or the consumption for the sports facilities of clubs. For the rest, the cause remains unknown for the time being.
