| Small community or institutional sources, such as hospitals. Must be located well away from residential communities due to potential for odors and nuisances<br/>

| Low for areas where available land is plentiful and low value<br/> | Low - Systems still require routine operation and maintenance tasks such as monitoring, weed and trash removal, scum and biosolids management<br/> 

| Can be very effective as primary treatment devices. May also be designed for secondary treatment<br/>

| Moderate - Some systems require tight specifications on construction<br/>

| Moderate - Take care to ensure the source wastewater is free of chemicals or disinfectants which can kill microbes that produce biogas<br/> | Ineffective for human waste only.&nbsp; When waste includes animal manure, may produce enough biogas to meet cooking fuel demands
