A simple model for the urban water cycle is presented, based on mass balances for water and phosphorus. This model is used for the evaluation of the sustainability rate of the urban water cycle. This type of model is to be used in an early stage of town planning, to compare several possible measures. In general, contributing to achieving a more sustainable urban water management. A sensitivity analysis was performed to rank the management options and additional measures to their contribution to the sustainability rate of the urban water cycle. A module for the calculation of cost was linked to the model, revealing the relation between cost and the sustainability rate for a wide range of scenarios. The results show that an improved separated sewer system and the use of a local ground water source have the biggest impact on the sustainability rate. A slightly positive correlation between investment cost and the sustainability rate was found as well.
