Overview of WERF's Collection System Related Research Activities

Research on issues related to wastewater collection system infrastructure (including sewers) sponsored by the Water Environment Research Foundation (WERF) has increased over the past five years as the industry began focusing more attention on these underground assets and their role in wet and dry weather related flows as it impacts water quality, public health and ecosystems. WERF has 12 completed and ongoing research projects valued at over $1.9 million in this area. Additional research needs have also been identified for the near and long-term future by WERF Subscribers and from ongoing research. This paper provides an overview of WERF, presents highlights of selected projects, and identifies potential areas for future research.
