1.13 Drainage
Does this dwelling have drainage:
[] 1 Connected to the public system? Go to 1.16
[] 2 Connected to a septic tank? Go to 1.16
[] 3 With a discharge to a gully or crack? Go to 1.16
[] 4 With discharge to a river lake (or sea)? Go to 1.16
[] 5 Does not have drainage? If it has sanitary services per question 1.9, go to 1.14 otherwise go to A1.15
The objective of the question is to identify if dwellings have a system of eliminating residual waters (waste waters, from the lavatory, kitchen sink, etc) and classify them according to the place where the system sends them.
A drainage system is an instillation of pipes that is planned and built in a dwelling to eliminate human remains and/or water from the lavatory, sink or shower. The system can drain to a public drainage system, the sea, a gully, etc.
Collecting the drainage is asked with three questions, since the informant does not always understand what is to be learned with the first question.
[graphic of the question from the census form]
When public drain pipes at a regional level are known by other names, for example: tube, tubes, drain, sewer system, they can be mentioned as synonyms for a better understanding for the informant.
If a dwelling has drainage, circle the corresponding option, from 1 to 4 and don't ask questions 1.14 Waste water, and 1.15 Soapy waters, and continue with question 1.16 Electricity.
[p. 73]
If an informant says that a dwelling does not have drainage, consult the information of question 1.9 Sanitary service. If here it was registered that there is some type of service (options 1 to 4), ask question 1.14 Waste waters. If it is written down that it does not have sanitary service (option 5) go to question 1.15 Soapy water.
