Drainage, Plumbing, Sanitation and Water Disposal
We get a number of requests asking us for the number of toilets, urinals, wash-hand basins and baths that have to be installed in buildings. This depends on how many people will live or work in a particular building. Part A20 states that:
“The occupancy of any building shall be classified and designated according to the appropriate occupancy class given in column 1 of table 1 and such classification shall reflect the primary function of such building: Provided that, in any building divided into two or more areas not having the same primary function, the occupancy of each such area shall be separately classified.”
There are two tables below Table 5 for residential accommodation and Table 6 for personnel in the workplace these are extracted fron the SANS 10400 Part P – Drainage.
