Urban drainage & sewer systems

Ensuring the transportation of waste water, without significant flooding and without ecological nuisance for humans and the environment is one of the main international environmental policy objectives of the 20th and 21st centuries.

Waste water is a precious resource in itself: it has many uses, both in terms of reuse of water (grey water) and in terms of heat recovery and energy optimization. This increases the requirements for our current sewer systems. The objective is not only to keep waste water inside the (separated) system and deliver it to the waste water treatment plant (WWTP), but also to manage flooding and ensure options for water reuse and heat recovery.

These new developments are in stark contrast to the needs in different European Countries: the development of a solid, basic sewer infrastructure, including treatment installations, is still one of the main priorities for the EU, the World bank and the European Investment Bank. Hence the international two-track policy?
