Environmental health requirements

Septic tank removal

The City requires all septic tanks and leach drains be decommissioned and removed prior to any demolition work. 

Decommissioning involves the pumping out or emptying septic tanks and leach drains and the removing them from the site.

Once the system has been emptied, the applicant must submit a Controlled Waste Tracking Form to the City’s Environmental Health Department.

Asbestos removal

If a building or structure contains asbestos materials, the Health (Asbestos) Regulations 1992,  requires 'reasonable' measures to be taken to prevent asbestos fibres entering the atmosphere.

Any business contracted to remove more than 10m2 of asbestos is required to hold an Asbestos Removal Licence (issued by Worksafe WA).
