A properly designed washdown bay contains wastewater, prevents contamination and supports compliance with SA Water and EPA requirements. We work with transport depots, workshops, council depots, construction and agricultural businesses to design, install and maintain systems tailored to each site.
We also handle trade waste in Adelaide, large diameter drain cleaning in Adelaide and backflow prevention in Adelaide, so one call covers the whole job. Browse our full range of commercial plumbing services in Adelaide, or book a plumber online in under a minute.

Washdown Bays questions
Washdown Bays for Adelaide businesses: what you need to know
These are the questions Adelaide business owners ask us most about washdown bays, answered by plumbers with 70+ years of local experience.
Do washdown bays need SA Water approval?
Usually. Washdown water is trade waste, so bays generally need approval and correct pre-treatment before connecting to sewer.
Which businesses need a washdown bay?
Transport depots, councils, mines, farms and plant hire yards that wash trucks, machinery or equipment on site.
What treatment does a washdown bay need?
Most need a silt trap and an oil separator, and some need a roof to keep rainwater out of the sewer.
Can you maintain existing washdown bays?
Yes. We clean silt traps, service oil separators and fix drainage so your bay stays compliant.
