In accordance with United Nations Sustainable Development Goals the future focus should be:
Wastewater is not a problem.
Wastewater is an asset, and everything should be reused
Sludge is a significant hassle and expense when treating wastewater. Using simple technologies, sludge can be reused typically as fertilizer or energy. Sewage sludge is a carbon-neutral biomass and could be an effective resource for reducing CO2 emission and help prevention of global warming. Among lots of biomass, sewage sludge has an advantage that the generated amount and quality is almost constant throughout the year, so in business fields in which lots of fossil fuel is used, sewage sludge has been considered as an effective new energy resource for prevention of global warming.
The report describes an operational system where sludge from wastewater using with simple means is converted to charcoal.
Wastewater treated to sufficient quality can be reused typically for irrigation, toilet flushing or other secondary use.
Finally, the report describes how poor quality water from rivers and bad wells can be converted to drinking water.
