Wash Bays for Heavy Equipment & Trade Waste Systems

Scooper Plumbing designs, installs and services wash bays and trade waste systems for heavy equipment, industrial sites and commercial operations. We specialise in oil water separators, compliant drainage solutions and purpose-built wash bay construction, tailored to site conditions, environmental requirements and council regulations.
Every wash bay is different. The correct system depends on:
  • Equipment type
  • Wash frequency
  • Contaminants present
  • Water reuse or discharge requirements
  • Council trade waste rules

What Is a Wash Bay

A wash bay is a dedicated area designed to safely wash down heavy equipment, machinery, vehicles or industrial assets while controlling contaminated wastewater. Wash bays prevent oil, grease, sediment and pollutants from entering stormwater systems, creeks and soil, protecting the environment and ensuring regulatory compliance.

Custom Engineering

Wash Bay Design & Construction

We design and construct wash bays to suit your operational needs and site layout. Our role is to ensure your wash bay is effective, compliant and practical for daily use.

Layout & Drainage Design

Practical wash bay layouts with correct drainage falls and runoff control.

Concrete & Containment Works

Slab preparation, bunding, and containment built for heavy equipment use.

Runoff & Trade Waste Control

Systems designed to capture oils, sediment, and contaminants before discharge.

Treatment System Integration

Seamless connection with approved treatment and separation systems.

Treatment Options

Recommended Treatment Solutions

We recommend the most suitable treatment solution based on your wash bay usage, site conditions and council trade waste requirements, ensuring effective separation, compliance and long-term reliability.

Oil Water Separators

For separating oils and hydrocarbons from wash-down water.

Filtration & Recycling Systems

Designed for water reuse and reduced waste discharge.

Catchment & Storage Systems

Controlled collection for removal or off-site disposal.

Combined Treatment Solutions

Tailored systems to meet site-specific and council requirements.

New Addition

Oil Water Separators & Trade Waste Systems

An oil water separator (OWS) is designed to separate oil & hydrocarbons from wash water before discharge or reuse. Oil water separators can:
  • Direct oil to a catchment area for removal
  • Allow treated water to be reused for washing
  • Allow treated water to be discharged to sewer (where approved)
  • Prevent environmental contamination

Technical Specs

Oil droplet size

Smaller droplets separate more slowly and need system design.

Oil density

Different oils separate at different rates based on weight.

Water temperature & viscosity

Hot or thick water affects how efficiently oils separate.

Flow rate (daily & peak)

Systems must handle both normal use and high-demand periods.

Contaminant concentration

Higher levels of oil and solids require stronger treatment capacity.

Costs & Timeframes

Understanding Costs

Wash bay installations vary significantly in price depending on site conditions.
Because every project is different, pricing is assessed on a site-by-site basis. We provide clear advice upfront so you understand the most cost-effective and compliant approach for your business.

Wash bay construction costs vary depending on:
  • Size of the wash bay
  • Ground preparation requirements
  • Drainage complexity
  • Type of oil water separator required
  • Whether water is reused or discharged
  • Roofing or enclosure needs
