OH2 Sanitation



Intent 1:

To exempt certain fixture drains from the requirement for an indirect connection in Subclauses to, and to permit direct connection to pipes that:

  • are terminated to form an air break above the flood level rim of fixtures that are directly connected to storm drainage systems, and
  • are extended through roofs when fixtures on 3 or more storeys are connected to them.

This is to limit the probability that backflow will lead to sewage contamination of clear-water waste fixtures and devices, which could lead to unsanitary conditions, which could lead to harm to persons.
