Initial text
Ventilation subsystems shall be provided in both sewer and rainwater systems. Primary Ventilation, Secondary Ventilation, Tertiary Ventilation, and Ventilation with Aeration-Ventilation Valves subsystems will be used.
Primary Ventilation:
A single ventilation system is considered adequate in buildings up to 7 stories or up to 11 if the downspout is too large and the drainage spigots are less than 5 m.
So I take it that at least primary ventilation has to be done.
