Discharging industrial trade wastewater is an operational, environmental and safety risk for us and the community. You must have written approval to connect your business to our network, and properly install and maintain appropriate treatment equipment. Commercial trade wastewater has different requirements.
Trade wastewater is wastewater produced at industrial or commercial premises that contains substances that could affect the environment or the health of the community. It may even affect our ability to serve the community by damaging our equipment. It includes wastewater transported by vehicle, including septic effluent. It also includes wastewater from ships and boats, contaminated groundwater and contaminated surface water.
If your business is listed below, it's likely to produce industrial trade wastewater:
If you're not an industrial trade waste customer, you might be a commercial trade waste customer. Commercial customers must install specific treatment equipment before discharging commercial trade wastewater into our systems.

We'll consider an application to discharge groundwater during a site remediation if you:
An open area is defined as any unroofed or partially roofed area where water collected on the surface can discharge into our wastewater system. Our base position is that no open areas discharge to our wastewater system. However, we understand that in some situations only limited options will be available to manage the discharge of contaminated surface water from open areas.
Discharge from open areas is classified as industrial trade wastewater. Therefore, approval to discharge from an open area to our wastewater network is managed under a Consent to discharge industrial trade wastewater.
You need to apply for approval to discharge industrial trade wastewater through Sydney Water Tap in. If we approve your application, you'll be required to install a first flush system. The first flush volume must be treated to meet our acceptance standards before discharge. To apply, you'll need to provide:
If contaminated groundwater or surface water is collected during excavation and construction, it must not be discharged to our wastewater network. It must be treated and discharged to the site's stormwater drainage system. Talk to the EPA or local council about your requirements.
