You can request copies of 'as-constructed' drainage plans for residential dwellings and commercial premises. Note that plans may not be available for all applications. The plans detail exactly how the drainage was constructed at the time the dwelling or premises was built. These plans may vary from the original designs.
Residential house drainage plans for detached houses and attached dwellings such as townhouses (Class 1a or Class 10a):
- These plans show the in-ground private sanitary drainage within a property that connects plumbing fixtures within the building to a sewer connection or on-site sewerage facility. They may not show water supply or stormwater drainage.
Commercial as-constructed drainage plans or large requests for apartments and commercial premises (Class 1b and Classes 2–9):
- Large requests may require a quotation (for example: multi-unit buildings, shopping centres, hotels, hospitals, factories).
