Abstract

Many of the wastewater collection systems in the USA were developed in the early part of the last century. Maintenance, retrofits, and rehabilitations since then have resulted in patchwork systems consisting of technologies from different eras. More advanced and cost-effective methods to properly rehabilitate these systems must be considered to guarantee sustainability into the future. Achieving sustainable development presents a challenge to deliver new and innovative infrastructure and facilities needed to serve society while protecting the environment. In the context of this paper, sustainable development would provide new and improved solutions to existing and emerging problems associated with wastewater collection system infrastructure. Such solutions would, for example, include consideration of innovative approaches and practices for identifying and rehabilitating problems in existing systems and ways of preventing these problems in new construction. The paper focuses on technical issues and research needs in three major areas: (1) assessment of system integrity; (2) operation, maintenance, and rehabilitation; and (3) new construction. Many of the issues and needs discussed were identified at a USEPA sponsored experts workshop on infrastructure problems associated with wastewater collection systems.

美国污水收集系统基础设施研究需求
美国的许多污水收集系统是在上个世纪初开发的。从那时起,维护、改造和修复导致了由不同时代的技术组成的拼凑系统。必须考虑更先进和成本效益更高的方法来适当恢复这些系统,以保证未来的可持续性。实现可持续发展提出了一项挑战,即提供服务社会同时保护环境所需的新型创新基础设施和设施。在本文的背景下,可持续发展将为与废水收集系统基础设施相关的现有和新出现的问题提供新的和改进的解决方案。例如,这种解决办法将包括考虑查明和恢复现有系统中的问题的创新办法和做法,以及在新建筑中防止这些问题的方法。本文重点研究了三个主要领域的技术问题和研究需求:(1)系统完整性评估;(二)运行、维护和修复;(3)新建。在美国环保署主办的有关污水收集系统基础设施问题的专家研讨会上,讨论了许多问题和需求。
