Answer
Correct option: D.
All of the above
To improve sanitation, low - cost onsite sewage disposal systems are being encouraged.
Examples are septic tanks, chemical toilets, composting pits.
Septic tanks are suitable for places where there is no sewerage system, for hospitals, isolated buildings or a cluster of $4$ to $5$ houses.
Some organisations offer hygienic on - site human waste disposal technology.
These toilets do not require scavenging. Excreta from the toilet seats flow through covered drains into a biogas plant.
The biogas produced is used as a source of energy.
A chemical toilet collects human excreta in a holding tank and uses chemicals to minimize odours.
These toilets are usually, but not always, self - contained and movable.
A chemical toilet is structured around a relatively small tank, which needs to be emptied frequently.
