FISHGLOBE REVOLUTIONISES THE FUTURE OF PLASTIC STRUCTURES FOR MARINE CONDITIONS Page 6 SAFEGUARDING THE DRINKING WATER IN URBAN AREAS IS CRITICAL Page 8 FLOW MEASUREMENT REVEALS LEAKS IN THE WATER SUPPLY NETWORK Page 12 Dear reader, he water supply and wastewater infrastructure in many regions across Europe is ageing. Despite the high quality of drinking water in the Nordic countries, the condition of the old pipe networks poses challenges. For example, Tin Finland most of the network was built between 1960 and 1990 and in the biggest cities parts of the network are over 100 years old. According to a recent study in Finland (ROTI 2019), 12% of the sewer network and 12% of the potable water network has deteriorated and there is an increasing need to renovate the old networks to both ensure water quality and minimise water losses. In Finland, 68 million m3 of mains water is lost every year and a substantial part of this is due to leakages (SYKE 2018). In Sweden, the total leakage of clean drinking water is about 15% on average, corresponding to 99 million m3 (Svenskt Vatten 2019). This is not only a waste of clean drinking water – resources used to collect, treat and pump the drinking water are also wasted. Losses of water, and in issue 2/2019 particular leakages, are relevant for distribution network efficiency in all European countries. New innovations are needed to help solve these challenges.

However, there is a risk, especially in former industrial sites, that the soil contains toxins that can infiltrate ordinary pipes.
