Liquid waste removal is the collection, transport and appropriate disposal of liquid waste generated or stored on a site.

Liquid waste management covers the identification, collection, handling, transport and appropriate disposal or further management of liquid waste. It can involve hazardous and non-hazardous waste, including wastewater, oily liquids, chemical liquids, sludge, sewage and contaminated runoff.
The appropriate approach depends on the source, composition, volume and site conditions. For industrial liquid waste management, understanding these factors helps determine the collection method, transport requirements and appropriate liquid waste disposal pathway.
CSA's liquid waste collection services cover a broad range of waste streams and site applications. The removal method depends on the waste characteristics, quantity and where the material has accumulated.
CSA Specialised Services provides liquid waste management services with a focus on safe operations and compliance with applicable health and safety requirements.
- Industrial and commercial facilities
- Petrol stations and garages
- Car washes
- Utilities and treatment plants
- Mines and resource sites
- Drainage and infrastructure assets
- Food and beverage operations
- Marine applications
- Residential requirements
The service required depends on the waste generated by the site's activities and the asset or system from which it needs to be removed.
Where drainage assets also need attention, CSA can help with clearing blockages and cleaning the affected drains as a separate service.
Frequently Asked Questions
A range of liquid waste can be collected and removed, including oily water, sludge and silt, sewage, waste oil, hazardous liquid and chemical waste, stormwater, food and beverage waste, and non-destructive digging slurry. Liquid waste can also be generated from pits, treatment plants and drainage infrastructure.
Yes. Hazardous and non-hazardous liquid wastes can both require specialist collection, transport and disposal. The appropriate handling method depends on the waste classification, composition and disposal requirements.
Liquid waste removal generally involves identifying the waste, collecting it from the site and transporting it for appropriate disposal or further management. The equipment and removal method required will depend on the type and quantity of waste and the site conditions.
After collection, liquid waste is transported for appropriate disposal or further management according to the type and composition of the waste. Different waste streams may require different handling once they leave the site.
Improper liquid waste disposal can contaminate soil and waterways, potentially affecting water quality, aquatic ecosystems, vegetation and surrounding land. Appropriate collection and disposal help reduce the risk of liquid waste entering the environment.
Liquid waste removal costs vary depending on factors such as the type and quantity of waste, site conditions, access requirements and the equipment and labour required. A site-specific assessment is generally needed to determine the appropriate service and cost.
Liquid waste removal is commonly required across industrial and commercial facilities, utilities, marine operations, treatment plants, petrol stations, car washes, mines, drainage infrastructure, and food and beverage operations. The need for removal depends on the waste generated by the site's activities.
Yes. Liquid waste, sludge and accumulated residues can be removed from tanks, pits, catch pits and interceptors as part of cleaning or waste-removal activities. The required method depends on the waste present and the site or asset being serviced.
