The present state, at the centenary o f the city’ s first modern water works system,

may be seen from the map (figure 38, opposite page 130) where the principal ground

water plants are shown, together with the contours o f the ground water table.

The cool, sterile ground water is collected by siphon conduits, and is treated with

aeration and subsequent filtration to remove iron and manganese. The water is

pumped from the different plants under full pressure to the taps and to the high

level reservoir at Tinghøj which contains 230,000 cubic metres. The capacities o f

the different ground water plants are shown on page 194, table Y I.

The principal part o f the water is supplied through water meters but in old houses

water is still paid according to area and number o f taps.

In 1926 a Danish water act was passed regulating the rights to the ground water;

by this act water courts were formed which decide upon all questions o f the use and

protection o f ground water.

The present water consumption amounts to about 82 million cubic metres yearly?

a part o f which is supplied in bulk to surrounding independent municipalities.

Extension works must be carried out in the coming years, partly by exploiting

still more distant ground water districts, partly by taking lake water into use.

At Søndersø, a lake 20 km to the north-west, is planned a modern surface water

plant, also for peak loads. Taste and odour should here be removed from the lake

water to make it suitable for mixing into the ground water production.
