Onsite Management Systems 2100 (OMS 2100) is an innovative, inclusive, onsite wastewater management system developed by Graham Knowles at the National Onsite Demonstration Program (NODP). OMS2100 focuses on community efforts to manage conventional, innovative, and alternative technologies for single family homes, clusters of homes, and small communities. OMS2100 is a new way of viewing local onsite situations to assist America's small communities in their efforts to protect public health along with improving water quality and sustaining the environment.

OMS2100 is a self-explanatory, simple to use, step-by-step approach to help local leaders and community constituencies see the onsite wastewater "big picture." OMS2100 provides essential elements to help communities better understand their "current reality" and to strategize action steps for sustainable solutions.

OMS2100 is a "compass" to frame and guide community dialogues -- a set of "guiding ideas" for effectively integrating technology and management for long-term wastewater management solutions. Using an OMS2100 approach will ensure that onsite principles, policies, processes, procedures, practices, resources, and responsibilities are implemented, executed, maintained, monitored, reviewed, and revised as necessary.

In a nutshell, OMS2100 is a "set of lenses" providing perspective to community wastewater strategies. Working within the context of an OMS2100 approach, communities can mold effective management models to meet local needs. OMS2100 is a practical tool to assist communities in continually improving the process of onsite wastewater management within existing regulatory requirements in the legislative landscape.
