One of the goals of the APUSS project (assessing infiltration and exfiltration on the performance of urban sewer systems) is to assess sewer exfiltration, in order to support cities and operators to define problem-oriented rehabilitation strategies. In this paper, we review various methods currently used for the estimation of exfiltration and discuss data needs and applicability for rehabilitation planning. Although each approach has its individual advantages and drawbacks, we identified pressure tests and tracer methods to have the highest potential for decision support in rehabilitation planning. With regard to future challenges (e.g., micropollutants) such methods might play a key role in integrated sewer management.
APUSS项目（评估城市排水系统性能中的入渗和出渗）的目标之一是评估排水管道出渗情况，以支持城市和运营者制定面向问题的修复策略。在本文中，我们回顾了目前用于估算出渗的各种方法，并讨论了修复规划中的数据需求和适用性。尽管每种方法都有其各自的优缺点，但我们认为压力测试和示踪剂方法在修复规划的决策支持方面具有最大潜力。对于未来的挑战（如微污染物），此类方法可能在综合排水管理中发挥关键作用。
