Sydney Water Trade Waste Compliance
More than five million people live in Sydney, the Illawarra, and the Blue Mountains. This area is serviced by Sydney Water, which is the largest wastewater service provider in Australia. Each day 1.5 billion litres of wastewater is collected and processed by Sydney Water. Their network is made up of over 25,000 km of piping, almost 700 pumping stations, 14 recycling plants, and 16 wastewater treatment plants.
Sydney Water has also developed a reputation as one of the most proactive wastewater service providers in Australia. Their hydrocarbon limits are much more stringent than most other states, and their inspections are known to be very thorough.
Key trade wastewater limits for Sydney Water compliance
Sydney Water compliance standards for trade wastewater are published online. The purpose of these limits is to protect the workers at Sydney Water, ensure that public health is maintained and also protect the environment from pollutants. Some contaminants may also be damaging to Sydney Water equipment if not strictly controlled.
PH outside of these limits may corrode piping and equipment and negatively impact on wastewater treatment processes, which are microbial in nature.
Petroleum hydrocarbons (flammable)
10 mg / L
Most States have a limit of 30 mg / L highlighting the high standards of Sydney Water.
Types of Sydney Water trade waste agreements
There are two types of trade wastewater agreements with Sydney Water. The first is for commercial trade wastewater and the second is for industrial trade wastewater. Written approval must be obtained from Sydney Water before any trade wastewater is actually discharged into the sewerage system.
Commercial trade wastewater agreements cover businesses like retail food, automotive, commercial laundries, photographic, shopping centres with pre-treatment, car washes, mechanical workshops, and some other activities. Some of these commercial activities may require pre-treatment of wastewater before it is allowed into the Sydney Water system. This could include oil separators, grease traps, and other processes.
Industrial trade wastewater agreements cover manufacturing, textile facilities, the petroleum sector, cement, printing, and surface coatings - to name a few. Trade wastewater must meet the Sydney Water compliance standards, and is subject to random testing to ensure compliance.
Sydney Water trade waste application process
There is a standard process to obtain a Sydney Water trade waste agreement.
- Submit your application with details of your activities.
- Sydney Water evaluates your application and may request additional information.

- Inspectors from Sydney Water inspect your facility should they deem it necessary.
- A consent form is issued by Sydney Water detailing the terms of the agreement including acceptance standards.
- Periodic tests of your trade wastewater will be conducted to determine your compliance. In addition, Sydney Water keeps a close watch on wastewater quality within the system and can track back to potential sources should there be an excursion.
