This is the Gisborne Trade Waste Bylaw, effective from 1 July 2021.
The purpose of this bylaw is to:
- Protect people and the environment from potential adverse effects of harmful substances discharged to the public wastewater system.
- Protect the public wastewater system from damage and provide for the efficient operation.
- Assist treatment plants within the public wastewater system to process wastewater and produce biosolids of a guaranteed quality.
- Encourage waste minimisation, cleaner production, efficient recycling and reuse of waste streams at business premises.
- Enable Council to carry out its compliance monitoring and enforcement functions.
(1) Clause 9(3) and (4) and paragraph (b) of the definition of prohibited waste in clause 5(1) (which relate to mortuary waste) come into force on a date determined by resolution of Council.
(2) The rest of this bylaw comes into force on 1 July 2021
Clause 2(1) provides for the later commencement of the provisions which prohibit mortuary waste from being discharged into the public wastewater system.
(1) This bylaw applies to the district of the Gisborne District Council.
Trade waste is liquid waste that is created by any Trade Premises and discharged to the public wastewater network.
Limits for concentration levels are set out in this Bylaw (see Schedule 1). Any trade premises that produces liquid waste that exceeds these limits are required to have a trade waste consent. It is normal for wastewater from trade premises to be first treated on-site before entering the public wastewater network. This is because some substances – at certain concentrations - are detrimental to the wastewater network, the wastewater treatment plant processes, the environment, and to the health and safety of people working in the wastewater plant.
Council may refuse to accept any type of trade waste which is not in accordance with this bylaw section 196 of the Local Government Act 2002.
The WWTP uses a biological trickling filter to treat wastewater from the Gisborne urban area.
It is an essential asset, critical for protecting people and the environment from the harmful impacts of wastewater.
The effective and efficient operation of the WWTP depends on our community using the wastewater network in the way it is designed. This means – for domestic users: only flushing the 3 P’s, and for trade premises: adhering to their consent conditions and this Bylaw.
Gisborne District Council – Te Kaunihera o te Tairāwhiti (Council) is committed to the careful management of wastewater, for the protection of the health and wellbeing of our community and environment.
(1) The purpose of this bylaw is to:
