Many of the wastewater collection systems in this country were developed in the early part of the twentieth century. Maintenance, rehabilitation, and retrofits 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 in the future. Achieving sustainable development presents a challenge: delivering new and innovative infrastructure and facilities needed to serve society while continuing to protect the environment.

In the context of this paper, sustainable development would provide improved solutions to existing and emerging problems associated with wastewater collection system infrastructure. Such solutions would include, for example, identifying and rehabilitating existing systems and developing ways of preventing these problems in new construction.

This paper focuses on technical issues and research needs in three major areas:

  • Assessment of system integrity
  • Operation, maintenance, and rehabilitation
  • New construction

Many of the issues and needs discussed were identified at an EPA-sponsored workshop on infrastructure problems associated with wastewater collection systems.
