in the true sense of the word.
With a total length of approx. 594,334 km, public sewer networks generally represent the highest asset values of cities and municipalities. The value of private property development facilities can probably be assessed at a similar level. Creating the necessary awareness of this fact extends far beyond local political decision makers; the public must also be informed about the size of “their” underground assets. At the same time, these assets – similar to real estate – must be maintained and brought up to the latest technical standards.
The most recent survey by the Association for Water, Wastewater and Waste (DWA) on the condition of the sewage system in Germany has shown that, despite all efforts, one fifth of all public sewers will have to be refurbished in the short to medium term, and 14.3 % have not been assessed at all.
There is still a lot to do. The “Impulse pro Kanal” action committee
comprising twenty-two associations and organizations has therefore
set out demands in support of a functioning water and wastewater infrastructure that are more important than ever especially in times of increasing budget restrictions.
