Water bourne toilets

Key Criteria

- Dignity to every man, woman and child
- No sewage pollution
- Be a totally flush toilet
- Acceptable by the people
- Totally safe, hygienic and healthy
- Complete environmentally friendly
- Totally odourless
- Limited external water usage
- No dependency on expensive time consumingcivil reticulation
- No electricity needed
- Affordability

The Concept

The principle is that naturally-occurring micro-organisms as opposed to chemical possesses, are selected as a biological additive to the digester tank of the self-sustainable flushable, portable and/or fixed biological water-borne toilet.

The biological process occurring in the digester tank converts raw sewage into re-usable filtered water, ready for re-use to the toilet cistern.

The Science

The modern onsite wastewater treatment system (OWS) includes a wastewater soun (typically a dwelling unit), a tank-based treatment unit (e.g., septic tank), and a soil infiltration unit (e.g., subsurface trench, drain field or drip irrigation).

In these types of systems, water use from all fixtures and activities generates a combined raw wastewater which flows into a septic tank buried outside and adjacent to the dwelling unit or similar establishment.

Flow Pattern Design

  

Applications

- Rural areas, because of the difficulty in installing water-borne sewerage due to topographic factors, or to distances between villages
- Rural schools, which lack infrastructure
- Farming communities, for the same reason
- Camp sites, including holiday sites
- Densely populated informal settlements
- Special events
- Disaster management

Assembly

Product can be supplied as a pre assembled unit or it can be supplied in kit form to be assembled on site. This will make transport of the unit much easier and no heavy equipment will be needed for installation. The parts can easily be handled and carried by hand.

Special features

The top structure is moulded double sided causing it to have a cavity wall. The purpose for the cavity is to form a sealed tank. The roof of the top structure is designed in such a way that it will collect rainwater into the top section of the top structure for cistern supply water and into the middle section of the top structure to supply the hand wash basin with clean water for hand washing. Each toilet unit has a hand wash basin as a standard feature. On the roof is also fitted a solar panel which supply power to the recycle pump in the digester unit.
