Constructed wetland systems for liquid waste treatment scale very effectively to community level. A system serving 10-20 households can achieve significantly better effluent quality than individual septic systems while requiring less land area per household and creating a more productive landscape element.

The typical community-scale liquid waste treatment train includes: composting toilets or low-flush toilets, a primary settling chamber (septic tank function), a subsurface flow constructed wetland, and a surface flow polishing wetland before irrigation reuse. The wetland system supports food-producing plants and creates habitat.

Community-scale systems benefit from an operator — someone responsible for monitoring inflow and outflow water quality, maintaining pumps and distribution valves, and managing the wetland vegetation. This role can be part-time and rotated among community members with training.
