This is a water-based system that requires a [[Urine Diverting Flush Toilet | Urine-Diverting Flush Toilet]] (UDFT, U.6) and a sewer. The UDFT is a special User Interface that allows for the separate collection of Urine without water, although it uses water to flush Faeces. Inputs to the system can include Faeces, Urine, Flushwater, Anal Cleansing Water, Dry Cleansing Materials, Greywater and possibly Stormwater.
The main User Interface technology for this system is the UDFT (U.6). A [[Urinal | Urinal]] (U.3) can be an additional installation for the effective collection of Urine. Brownwater and Urine are separated at the User Interface. Brownwater bypasses a Collection and Storage/Treatment technology and is conveyed directly to a (Semi-) Centralized Treatment facility using a [[Simplified Sewers Sewer | Simplified]] (C.4) or a [[Conventional Gravity Sewer | Conventional Gravity Sewer]] network (C.6). Greywater is also transported in the sewer and is not separately treated.
Stormwater could also be put into the Gravity Sewer network, although this would dilute the wastewater and require Stormwater overflows. Therefore, local retention and infiltration of Stormwater or a separate drainage system for rainwater are the recommended approaches.
Guidelines for the safe use of Urine, Effluent and Sludge have been published by the World Health Organization (WHO) and are referenced on the relevant technology information sheets.
