What is an EcoSan toilet


The organized construction of urine-separated dry toilets with a double-chamber system (UDDT) gives utility companies the opportunity for the first time to offer an appropriate and economical sanitary service quickly and flexibly in areas without sewerage, in which the drinking water supply is often inadequate.

The whereabouts of all material flows (dry faeces, urine, gray water) must be decided at the beginning of the conception. Each disposal model must be designed depending on the specific conditions: If the transport or use of the products by the user is possible and desired, support should be given. In peri-urban situations in particular, however, it is usually necessary to remove at least the faeces, which enables post-treatment, e.g. in communal compost, and controlled removal and reuse.

The utility company of the city of Juliaca, for example, has developed an alternative disposal concept based on UDDT for a settlement with 750 houses, in which the collection of dry faeces is planned every 6 months. However, since high groundwater levels do not allow infiltration, the monthly urine transport to the municipal sewage treatment plant also had to be taken into account. 7 sewage treatment plants were provided for the treatment of the gray water. The monthly tariff for the service per household (without investment) is USD 2.70 here.

The households benefiting from this sanitary disposal concept “on wheels” benefit from significantly increased comfort and improved hygiene.
