THE DRYSAN TOILET

The DRYSAN toilet has been developed to reinvent the toilet in a way that enables people in all walks of life to have a simple, inexpensive, and compact and ouderless ablution facility that will raise their personal dignity, improve their health, and aid in the preservation of natural resources

The DRYSAN toilet may also be adapted for a squat toilet

BACKGROUND TO THE DRYSAN

The DRYSAN is NOT a composting toilet

The DRYSAN waterless and urine diversion toilet system is intended for use in areas where sewerage lines and sewerage works are unavailable, have been corrupted, or where chemical toilets are currently used. The system may also be used where household’s lack water or have a ‘green’ attitude to the environment.

The use of the DRYSAN extends to informal housing, low cost housing, smallholdings, disaster areas, water challenged areas, military facilities, lodges, farms and many other areas deprived of waterborne toilet facilities

The DRYSAN may be placed in the smallest of informal houses, mud huts, tents etc providing privacy for the occupants and safety at night where women and children do not need to leave their premises for ablution purposes. The installation requires only a small, flat, level (preferably solid) surface partially inside and partially outside the residence. The DRYSAN because of its simplicity can also be considered portable

Currently there are numerous formal, informal settlements and properties where water borne sewerage is collected in septic tanks, untreated pits and long drops. These long drops and sewerage pits may be at a residence or at distance from the residence, in a communal pit. A sewer line or channel may run to this communal pit, but often does not; excess sewerage often flows into the open, causing health problems and contamination risks for residents

Long drops, pits and chemical toilets (individual and communal) are sometimes emptied, but often infrequently and erratically. They are a major health hazard and have damaging environmental implications as the contents of the pits leach into surrounding ground, causing diseases and polluting underground and above ground water supplies (Known diseases include ascaris, salmonella, shigella, taenia, vibrio cholera, hookworm, ecoli etc)

The DRYSAN may further be used to replace chemical toilets that are inherently eco unfriendly, often very smelly because they are used communally. Furthermore chemical toilets are seldom emptied on a regular and consistent basis, and become a major health hazard

Long drops, faeces pits and chemical toilets are a major creator of smells and encourage the breeding of flies and parasites

The advantage of the DRYSAN is the separation of faeces and urine at source – the faeces is deposited in a sealed bin, bucket or bag and may then be removed from the DRYSAN unit when full

The size of the container or bag, and the toilet usage will determine the frequency of removal

The ability of the individual to remove the stored faeces from even the most crowded settlement makes this system unique. Trucks and tanks are not required. The removal of the faeces may be done by wheeling the bin or carrying the plastic bag to a local authority or private collection point (maybe a skip)

The urine may also be removed in a rolling container

Both urine and faeces are saleable products as both may be used as fertilizers
