This is a water-based system that requires a flush toilet and a Collection and Storage/Treatment technology that is appropriate for receiving large quantities of water. Inputs to the system can include Faeces, Urine, Flushwater, Anal Cleansing Water, Dry Cleansing Materials and Greywater. There are two User Interface technologies that can be used for this system: a Pour Flush Toilet (U.4) or a Cistern Flush Toilet (U.5). A Urinal (U.3) could additionally be used. The User Interface is directly connected to a Collection and Storage/Treatment technology for the Blackwater that is generated: either a Septic Tank (S.9), an Anaerobic Baffled Reactor (ABR, S.10), or an Anaerobic Filter (S.11) may be used. The anaerobic processes reduce the organic and pathogen load, but the Effluent is still not suitable for direct use. Greywater should be treated along with Blackwater in the same Collection and Storage/Treatment technology, but if there is a need for water recovery, it can be treated separately (this is not shown on the system template). Effluent generated from the Collection and Storage/Treatment can be directly diverted to the ground for Use and/or Disposal through a Soak Pit (D.7) or a Leach

Field (D.8). Although it is not recommended, the Effluent can also be discharged into the Stormwater drainage network for Water Disposal/Groundwater Recharge (D.11). This should only be considered if the quality of the Effluent is high and if there is no capacity for onsite infiltration or transportation offsite.
