Governance:
Ecological sanitation can be introduced and operated as decentralised systems. These systems can be built and maintained at the household and community levels. Primary treatment of pathogens can occur within the toilet unit, and secondary processing can occur within the community if necessary. If the resources of the toilet are recycled locally, there can also be decentralisation of food production. If the household or local community cannot use the contents that these toilets provide, they can be packaged and sold to farmers, gardeners, or others in need of fertilisers or compost. This increases employment opportunities at the local level, while keeping the environment clean and green. Current sanitation systems often need to subsidise investment costs with little hope of recovering those returns, in part because the valuable excreta is disposed and its resource value is lost. In addition to employment generation to manage the output of the toilets, local entrepreneurs have demonstrated that the production and sale of ecological toilets is possible, and training of users is both viable and possible from a behavioural perspective. Building pit latrines in cities can be a risky business, as often scarcity of land, inappropriateness of soils and lack of privacy are difficult to overcome. Ecological toilets, particularly urine diversion toilets, can be built into the home, reducing building costs for additional outside walls
