Unauthorised installation, alteration or operation of OSSM


Unauthorised installation or alteration of OSSM

Installing or altering on onsite wastewater system without an approval is an offence. Make sure you, your plumber or service agent are in possession of an approval before any such works commence.

There are no exemptions to this requirement and Council does not approve the installation or alteration to systems informally. Do not accept tradesmen advising otherwise.

Examples of altering a system include

  • Changing the treatment system
  • Changing the location of disposal
  • Changing how treated wastewater is disposed of i.e. if approved to dispose underground it cannot be changed to surface irrigation.
  • Altering the sanitary drainage fittings connected to the system

Repairs to an approved system that do not substantially change the system as approved are permitted without an approval, examples of repairs include:

  • Replacing components like for like
  • Repairing cracks or resealing tanks
  • De-sludge pump-out
  • Restocking consumables such as chlorine

Council cannot grant retrospective approval for any installation or alteration works that have already been undertaken, however depending on the circumstances it may be regularised through an Approval to Operate. For further information see Approval to Operate an Existing System of Sewage Management | CCC

Council will preference a conciliatory approach where a party is proactively seeking to regularise the unauthorised installation or alteration of a system but retains the option to instigate compliance action having regard to our Compliance and Enforcement Policy.

If you are unsure, contact Council’s Customer Service team on 4993 4100 and ask to speak to the Environmental Health Duty Officer.
