Opflow is primarily written by the people who read it and is the water community's primary network for operator-level workers. The award-winning monthly magazine presents new and established technologies and ideas that readers can apply to water treatment and distribution, as well as wastewater operations, through

  • informative case studies from operations personnel who tackled and solved common operations and maintenance problems,
  • detailed how-to articles that take readers step by step through new and tried-and-true processes, and
  • up-to-date regulatory and technical information that helps readers provide safe water to all.
Opflow is a trusted link among operators in small towns and those at large metropolitan utilities, allowing operators to share their experiences with others.

Opflow covers the full range of practices and issues faced by the people who run water and wastewater treatment plants and distribution systems. Below is a list of editorial highlights and bonus distribution opportunities planned for upcoming issues.
