System Template 9
This is a water-based system that requires a Urine-Diverting Flush Toilet (UDFT) 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.
This system is only appropriate when there is a need for the separated Urine and/ or when there is a desire to limit water consumption by using a low-flush UDFT (although the system still requires a constant source of water).
This system is most appropriate when there is a high willingness and ability to pay for the capital investment and maintenance costs and where there is a pre-existing treatment facility that has the capacity to accept additional flow.
