Major water savings at Prøvestenen

The effect of replacing old and leaking water mains can now be observed, with the investments saving CMP a lot of money

Following renovation of the water mains at CMP’s oil and dry bulk terminal, Prøvestenen in Copenhagen, the investment can now be directly observed in the form of reduced water consumption.

”We could see there was a difference in the amount of water being used by our tenants at Prøvestenen and the overall consumption registered for Prøvestenen as a whole. It was quite considerable. So there had to be leakage in the old mains system,” says Peter Landgren, head of construction at CMP.

”It is natural for old water mains to leak after a large number of years. We went right through Prøvestenen replacing the entire water mains system over a 5 year period (2008-2012). We can now observe the results, with a tremendous reduction in waste of up to 80%. There were large volumes which simply disappeared underground en route to the tenants, so the amount of expenditure we have now saved is correspondingly large.”

The lower wastage also entails an important environmental benefit in the form of saved water resources. At the same time, since the water mains have been replaced there have also been savings on labour resources in the form of less maintenance of the pipelines.

CMP has regularly upgraded Prøvestenen with new quay facilities and road surfaces etc. Prøvestenen has an area of about 1 million m2, and is ideally located for handling bulk for customers in Greater Copenhagen and Zealand. The products comprise stone, sand, gravel, cement and soil, as well as an oil terminal.
