Trade Waste is liquid waste generated by any industrial or commercial premises. This wastewater usually goes into the Napier City Council wastewater network (the sewers) to be treated at the Wastewater Treatment Plant in Awatoto, before being pumped into the ocean through a pipe on the sea floor (together with all Napier’s wastewater).Trade Waste can contain substances which can damage our infrastructure and our marine environment.
In order to make sure the system can cope and that the impact on the environment is minimal, the Integrated Trade Waste and Wastewater Bylaw regulates the quality and quantity of trade waste going into the NCC network. The Bylaw also allows NCC to set limits on wastewater, which may require businesses to do some treatment, and also to charge those businesses for the cost of conveying and treating the trade waste. This helps to reduce the effects of trade waste on the environment and spreads the cost fairly across trade waste producers.
Most businesses that are not retail stores and offices will be required to register as a trade waste customer. Once you have registered, your trade waste will be categorised into 1 of 4 of the categories outlined below.
Controlled and conditional trade waste customers will be required to provide an Environmental Management Plan (EMP). An EMP is a plan outlining how a consent holder will make provision for matters including, but not limited to:
A template can be downloaded here.
Businesses that produce high levels of fat, oils and grease such as food premises will be required to install and maintain grease removal systems.
Depending on the type of consent applied for, a site visit from a trade waste officer may be required.
Trade waste costs are covered by a user pays system designed to encourage improvements to the quality of trade waste discharged to the network.
If your business has been consented to discharge trade waste to the public wastewater system, you will be charged based on the characteristics of your trade waste. The majority of trade waste customers will be subject to affordable flat rates as outlined in the schedule of fees and charges while customers that have higher contaminant loads, higher flows or higher risk trade waste will have more personalised rates as determined by the charging model which is described in the Administration Manual.
