Runoff Model

At present, dimensioning of combined sewer detention basins in Germany is based actually on the rational formula and on the idea of the existence of the so-called “first flush”. New measurements and recent investigations have led to the questioning of this dimensioning procedure. An alternative developed in this paper is based on the application a storm-water-runoff-model (hydrological and/or hydrodynamic) in each special case. Input to the model is a period of at least one decade of continuous rainfall data (long term simulation). The sanitary waste water component is superimposed to the simulated runoff-hydrograph. The first flush-effect is neglected. The dimensioning of a detention basin is based on the determination of several quantities such as number, duration, peak discharge and volume of overflow events in relation to the total water detention volume of the system. The decision on final dimensioning has to be made with respect to the characteristics of the receiving water.

As a result of urbanization, the pollutant discharges from sources such as treatment plant effluents and polluted stormwaters are responsible for an unacceptable water quality in the receiving waters.In particular, combined sewer system overflows may produce great damage due to a shock effect. To reduce these combined sewer overflow discharges, the most frequently used method is to build stormwater storage tanks. During storm water runoff, the hydraulic load of waste water treatment plants increases with additional retention storage. This might decrease the treatment efficiency and thereby decrease the benefit of stormwater storage tanks. The dynamic dependence between transport, storage and treatment is usually not taken into account. This dependence must be accounted for when planning treatment plants and calculating storage capacities in order to minimize the total pollution load to the receiving waters. A numerical model will be described that enables the BOD discharges to be continuously calculated. The pollutant transport process within the networks and the purification process within the treatment plants are simulated. The results of the simulation illustrate; a statistical balance of the efficiency of stormwater tanks with the treatment plant capacity and to optimize the volume of storm water tanks and the operation of combined sewer systems and treatment plants.

The influence of various characteristics of combined sewer systems on the overflow load has been analysed by means of long-term simulation. Special attention was paid to the sewer sediment. A simulation model that has been developed for this purpose comprises an approach for the sediment transport. This approach has been calibrated by means of various values of pilot plants. It has been demonstrated that the importance of the first flush is dependent on the bottom slope. The ‘dry weather balance' has been defined as a parameter which allows the determination of the overflow load from sewer sediments.
