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

4. 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
