Faecal Sludge that is removed can be transported to a dedicated faecal Sludge treatment facility (T.13-T.17)([[Sedimentation - Thickening Ponds]], [[Unplanted Drying Beds]], [[Planted Drying Beds]], [[Co-composting]], [[Anaerobic Biogas Reactor]]).
In the event that the treatment facility is not easily accessible, the faecal Sludge can be discharged to a [[Transfer Station (- Underground Holding Tank)|Transfer Station]] (C.7).From there, it will be transported to the treatment facility by a motorized vehicle (C.3). A technology selection tree for faecal Sludge treatment plants is provided in Strande et al., 2014 (see Sector Development Tools, p. 9). (Semi-) Centralized Treatment technologies (T.1-T.17) produce both Effluent and Sludge, which may require further treatment prior to Use and/or Disposal. For example, Effluent from a faecal Sludge treatment facility could be co-treated with wastewater in [[Waste Stabilization Pond | Waste Stabilization Ponds]] (T.5) or Constructed Wetlands (T.7-T.9) such as a [[Free-Water Surface Constructed Wetland]], a [[Horizontal Subsurface Flow Constructed Wetland]], or a [[Vertical Flow Constructed Wetland]].
From the Transfer Station the Faecal Sludge must be transported to a dedicated Faecal Sludge treatment facility ([[Sedimentation - Thickening Ponds]], [[Unplanted Drying Beds]], [[Planted Drying Beds]], [[Co-composting]], [[Anaerobic Biogas Reactor]])) by a [[Motorized Emptying and Transport|motorized vehicle]].
All (Semi-) Centralized Treatment Technologies produce both Effluent and faecal Sludge, which require further treatment prior to Use and/or Disposal. Technologies for the Use and/or Disposal of the treated Effluent include [[Irrigation]], [[Aquaculture Ponds]], [[Floating Plant (- Macrophyte) - Pond|Macrophyte Pond]] or [[Water Disposal - Groundwater Recharge|Discharge to a water body or Recharge to groundwater]]. After adequate
treatment, Sludge can either be used in agriculture (D.5) or brought to a Storage/Disposal site (D.12).
when digging pits in order to avoid contaminating it. Although different types of pits are common in most parts of the world, a well-designed pit-based system with appropriate transport, treatment and use or disposal is rare.
