The Parameters Determination problem of the sewage system function

The urban sewage systems usually have no preventive development. The social development exceeds the urban sewage development, and urban sewage system is frequently overloaded and we don't know how the system exactly functions. The attempt to determine the real condition parameters, in purpose to model and to plan the further urban sewage system development is followed by many problems. The aim of this paper is to point out some concrete problems on the example of the city of Osijek and its sewage system. Osijek is the center of the region where the city itself has more than 100 000 inhabitants. The good watersupply development wasn't successfully followed by the sewage system development.The new main sewer has been under construction for the last 30 years so it is no wonder that the wastewater treatment plant is something that people have just started to think about.The experts have got the task to model the current condition and this model will be the base for modelling and planning the future conditions.Following this, precipitation-runoff monitoring and sewage system monitoring are installed in the area of Osijek. Five rain gauge stations are established. Discharge is measured on six gauge stations, and measurements are also established to define storm overflow. The experiences collected in this paper can be useful to the others in similar circumstances.
