180. In column H15 ask, 'where do members of this household go for toilet?'

Code the answers according to the categories given below (e.g., code '3' for pit latrine, '5' for cesspool, etc).

Sewage is the liquid waste matter drained away from the structure for disposal.

The main types of sewage disposal are:

(a) Main sewer means the sewage liquid waste from the structure is drained by pipes into a main tank of the estate. This type of sewage disposal is common in main urban centers like Nairobi, Mombasa, etc.

(b) A septic tank is a tank into which sewage is conveyed and remains until bacteria make it liquid enough to drain away. Examples of septic tanks are found in urban areas, where the tank is often located within the dwelling structure's compound. Ask the respondent if they have this tank in the compound or whether sewage drains into some main sewer.

(c) A bucket latrine is a bucket designed for human excrement. It is emptied occasionally. This type of waste disposal is rare, but can still be found in urban residential estates.

(d) A cesspool drains and collects liquid waste from dwelling units.
