THE WATER SUPPLY IN ARENDAL IS GOOD

There is a good supply of high-quality fresh water from several lakes in the area, and a new water treatment plant was built in 1998. Water pollution is a moderate problem, but the main sewage treatment plant is modern and treats three-quarters of the households in the municipality.

WHAT CAUSES PROBLEMS FOR THE WATER SUPPLY?

The wind from industrial areas in England and Central-Europe brings acid precipitation to Arendal and the rest of southern Norway. With the hard ground, lack of lime and the thin layer of soil it’s not possible to neutralize the acid rain.

Industrial spills and run-off from agriculture may also cause problems, but these are small when Arendal is concerned.

In addition, the capacity problems (especially when it comes to garden watering) and technical failure may create short supplying difficulties.

DRAIN WATER IS TAKEN CARE OF BY THE CLEANSING PLANT AT HIS+Y.

Today’s cleansing plants for this drain water is located in Saulekilen near Utnes at Hisøya. Here comes sewage from most of the households in Arendal. Being a mechanical plant, the cleansing effect has turned out to be good. The State has tightened up the rules concerning the drain water. A chemical cleansing process worth 111 mill. NOK (exclusive VAT) is being projected.
