[i]I have a question to colleagues about the removal and or replacement of vent pipes in the sewer system. Has anyone got a good method that works for the replacement of vent pipes in and around infrastructure? Would they share it with Kyogle Council? Are there any recommended contractors that carry out these works in the northern rivers area?[/i]

Vent stacks were installed in areas where there are traps installed on the service line at the lot boundary. In areas where there are no 'boundary traps' Council's gravity system is vented by house vents. You shouldn't remove vent stacks until you have enough premises that dont have 'boundary traps' otherwise:
1. the system will be inadequately vented and you will create septic issues (eg corrosion) and therefore odour problems for non-trapped houses, and
2. you may cause boundary traps to be sucked dry causing odour issues for those properties.
You can cut them down and put a McBerns the filter at gound level if the problem is aesthetic or the vent stack is structurally unsound. If the request to remove a vent stack is from a property owner, then they should pay its relocation, which is expensive.
