Since 1991, European Legislation on the urban treatment of wastewater requires local authorities to take into account the treatment of polluted water transported by the sewerage system and this during dry and wet weather conditions. In the seventies, the urban Community of Grand Nancy constructed storage tanks in its sewerage system in order to prevent flooding and wish today to use them to reduce and control the pollution discharges into the receiving water. This action is a part of a European LIFE project 1996-2000. The main aim of this project was to assess the effectiveness of reducing pollution of one particular retention basin, the 12,000 m3 Gentilly tank. This one has two operating modes: protection against floods during heavy rain and reduction of pollutant overflows during lighter rain. To assess its effect on the pollutant discharge, the HYDROWORKS DM software and its Real Time Control Module have been used, calibrated and validated. As this study is still in progress, this paper describes the studied site and the modelling results under different weather conditions and shows that the mathematical model can be used to simulate the operation of the catchment area and its associated sewerage system realistically.
自1991年以来，欧洲关于城市污水处理的立法要求地方当局考虑污水收集系统输送的污水的处理，且在旱季和雨季都要进行处理。20世纪70年代，大南锡城市社区在其污水收集系统中建造了储水池，以防止洪水泛滥，如今希望利用这些储水池来减少和控制排入受纳水体的污染排放。这一行动是1996 - 2000年欧洲LIFE项目的一部分。该项目的主要目的是评估一个特定的调蓄池——12000立方米的让蒂伊储水池减少污染的效果。该储水池有两种运行模式：暴雨期间防洪以及小雨期间减少污染物溢流。为了评估其对污染物排放的影响，使用了HYDROWORKS DM软件及其实时控制模块，并进行了校准和验证。由于这项研究仍在进行中，本文描述了研究地点以及不同天气条件下的模拟结果，并表明数学模型可用于逼真地模拟集水区及其相关污水收集系统的运行情况。
