'''An Aerated Pond is a large, outdoor, mixed aerobic reactor. Mechanical aerators provide oxygen and keep the aerobic organisms suspended and mixed with the water to achieve a high rate of organic degradation and nutrient removal.'''
}}
===Adequacy===
A mechanically aerated pond can efficiently handle high concentration influent and can reduce pathogen levels significantly. It is especially important that electricity service is uninterrupted and that replacement parts are available to prevent extended downtimes that may cause the pond to turn anaerobic. Aerated lagoons can function in a larger range of climates than [[Waste Stabilization Pond|WSPs]]. They are most appropriate for regions with large areas of inexpensive lands that are away from homes and businesses.
===Health Aspects/Acceptance===
The pond is a large expanse of pathogenic wastewater; care must be taken to ensure that no one comes in contact with, or goes into the water. The aeration units can be dangerous to humans and animals. Fences, signage, or other measures should be taken to prevent entry to the area.
===Maintenance===
A permanent skilled staff is required to repair and maintain aeration machinery. The pond must be desludged once every 2 to 5 years. Care should be taken to ensure that the pond is not used as a garbage dump, especially considering the damage that could be done to the aeration equipment.
