In 2019 there have been many large water network leakages in Helsinki, which have mixed the traffic, and the renovation schedule of Hakaniemi market place. This has revealed to general knowledge that large amount of the water of the capital is running in a network, which has been built in tsarist times in 1880’s.
Fifth of treated water is leaking to waste from poor pipe network
In the developed world, one is used to taking clean water as granted. Thus, the maintenance of water network and other common infrastructure have been neglected.
We should be more critical that the problems of water supply rise to general knowledge only when there is a showy water network leakage in a large city, traffic chaos, and economic losses. Or if the worst happens, regional drinking water becomes polluted.
Less known problem is that significant amount of already treated water is going to waste, because the poor water network is leaking. It has been estimated that approximately 20% of treated water is leaking to waste because of leaking pipe network in Finland.
The question is also about saving energy. When water is treated, it consumes energy. Energy production causes costs and carbon dioxide emissions. Poor and leaking network causes both extra indirect expenses and carbon dioxide emissions.
National responsible one is missing from water supply
In Finland, municipal water treatment plants are in charge of the water supply, and our production of drinking water is scattered. We have only a couple of large water treatment plants and hundreds of small ones. For instance, in Netherlands there are ten regional water treatment plants, which are in charge of distributing water.
Many of the researches made encourage the water treatment plants to corporatize and be joined together. As follows, economic benefit can be achieved, which could be used for improving the operability of water supply.
