This paper presents a historical review of some concepts and techniques used to manage sewer sediments and to cleanse sewers. Two aspects are illustrated: i) the use of egg-shaped and similar types of sewers in order to ensure self-cleansing velocities even during low low periods, and ii) the use of flushing tanks to scour deposited sediments and keep sewers free of deposits. After a brief survey of antecedent periods, the paper focuses on the evolution since the middle of the 19th century. Mainly based on French and English complementary examples, because both countries were leaders in the development of urban drainage in the period 1840-1880, the paper also provides information from Germany and the USA and shows that some aspects remained rather unchanged during 150 years while other have been completely revised during the same period.
本文对用于管理下水道沉积物和清洁下水道的一些概念和技术进行了历史回顾。阐述了两个方面：i）使用卵形及类似类型的下水道，以便即使在流量很低的时期也能确保自净流速；ii）使用冲洗水箱冲刷沉积的沉积物并保持下水道无沉积物。在对前期进行简要概述之后，本文重点关注自19世纪中叶以来的发展历程。主要基于法国和英国的补充实例，因为这两个国家在1840 - 1880年期间是城市排水发展的领导者，本文还提供了来自德国和美国的信息，并表明有些方面在150年里变化不大，而其他方面在同一时期则被彻底修订。
