However, this approach is taking increasingly sophisticated forms. The most elaborate and desirable of these is network asset management.

• The main aim of this approach is to limit the depreciation of the assets represented by the wastewater network. Because of its forward-looking nature, it is also a step in the right direction in the fight against :
