Small water systems face immense difficulties in meeting the requirements of the Surface Water Treatment Rule. This article describes partnerships formed between the state regulatory agency, communities, and consulting engineers in Oregon to assist small communities in meeting these requirements. A case study is presented of a small community, Westfir, Oregon, that successfully installed slow sand filtration, which has proved to be an effective and appropriate treatment technology. Also described are several associated demonstration projects undertaken by state water program staff to develop pilot filter and design guidelines for use in future projects. Includes 5 references, tables, figures.
