This document discusses how treatment ponds can be used to treat lightly polluted or wastewater through natural processes. Treatment ponds work in all environments and use aerobic and anaerobic bacteria as well as algae to break down waste materials through oxidation and other reactions, with shallower ponds being aerobic and deeper ponds being anaerobic. The type of pond used depends on factors like the temperature, pH, and content of the water as well as the type of wastewater and location.
