Problems and restrictions in the operation of own water supply systems
Problems and restrictions can be caused by:
» Corrosion » Limescale formation » Blockage of pipes, fittings and equipment with sludge » Clouding, discoloration, odour and taste problems » Increased nitrate levels, microbial contamination
Causes:
» Free aggressive carbonic acid » Hard water with excessive salt content » Iron and manganese compounds » Microbial contamination
The problem: Everybody
has the right to enjoy top-quality drinking water. However, spring
water does not always come up to scratch. Drinking water regulations
take into account possible technical problems and also health risks. The operator of the spring is responsible for maintaining proper drinking water quality.
Scale formation Increased
hardness constituents (total earth alkalis) can lead to stubborn
deposits and encrustations in piping systems, fittings and equipment.
Limescale deposits
Corrosion If
water, especially soft water, contains too much free aggressive
carbonic acid, this can attack metal pipes and fittings. Increased
chlorine and sulphate contents also promote corrosion and attack
concrete.
Pipe corrosion
Clouding materials
After
heavy rain, especially in the case of springs with a proportion of
surface water, the supplied water often contains an increased
proportion of suspended materials. On the one hand, this can cause
mechanical contamination with dirt, which can lead to the sudden
failure of installations and systems, and on the other, the organic
impurities contained in the water can also mean microbiological
contamination.
Iron and manganese content Iron
and manganese impurities are the problems most frequently encountered
with spring water. These lead to contamination of pipes and
installations with sludge, and to discoloration of the water, possibly
resulting in corrosion.
High nitrate levels Under
unfavourable conditions, increased nitrate levels in spring water can
be converted into nitrites or even nitrosamines. While nitrates can
lead to so-called "cyanosis" in infants, nitrosamines are also thought
to be carcinogenic.
High salt levels Water
containing high salt levels is harmful to health. Such water also has
strong properties that favour corrosion. When used for watering, it
contaminates the ground with salts, killing off plants. Spring water
containing salts is mainly found in coastal areas and on islands.
Microbial contamination The
risk of microbial contamination is particularly prevalent in catchment
areas where animal faeces are found, after heavy rain or when surface
water penetrates the ground water. Coliform germs in particular, such
as Escherischia Coli, can cause severe illnesses of the intestinal
tract.
