A possible tool for developing strategic cleaning plans is a geographic information system (GIS) used for the acquisition, management, processing, analysis and visualization of spatial reference data. The GIS comprises of a graphical user interface and a data base (e. g. Access, Oracle, etc.) that stores all section parameters, such as nominal size, material, section length, gradient, photos representing the actual status, etc.

By combining these data with objects (point objects, line objects and area objects), they can be retrieved very quickly in a visualized form. Thus, the illustration of complex interrelations is simplified. In addition to manholes and network sections, the deposit situation in the sewer network, the tree population in the area of road gullies and other sources of mineral solids can also be depicted.

In the course of strategic cleaning planning, not only drains and sewers, but also other structures of the drain and sewer system have to be considered (e.g. access shafts, road gullies/storm drains, sludge traps, inverted siphons, pumping stations and stormwater tanks).

Another crucial aspect in the development of cleaning plans is the prevention of outside solids from entering into the sewer system. An on-site cause analysis has to be carried out to achieve a sustained reduction or even avoidance of deposits
