Trade Waste Bylaw 2018 - questions and answers

What's the Trade Waste Bylaw?

The Trade Waste Bylaw 2007 is a legal document we use to manage trade waste discharges that enter our wastewater system. It allows us to manage and prevent sewer overflows, blockages, infrastructure damage, protect the environment, while also protecting the health and safety risk to our workers and our community.

The bylaw and its rules are for all businesses, corporations, groups, or individuals who want to connect, disconnect, open manholes, discharge trade waste or domestic waste into the Council system, or discharge trade waste or domestic waste directly into the wastewater treatment plant facility. It also assists us (Council) meet our Resource Management Act requirements and provides for an equitable spread of costs and promote the use of waste minimisation and cleaner production techniques.

We recently carried out a review of the Trade Waste Bylaw 2007 to make some improvements. To get feedback we ran formal consultation in late 2018 to make sure we've got it right.

What changes are being made?

The 2018 will replace the 2007 Bylaw with only a few key amendments: 

Add a new grade of discharger

We’re adding a ‘controlled’ classification to the three existing classifications. This means we could classify low-risk discharges separately and manage them accordingly.

While they don't present a significant risk to the wastewater system, these discharges could cause localised disruption, nuisance and additional operational costs if they’re not appropriately managed.

We estimate there to be around 30 existing dischargers that would fall into the new classification. This means that some dischargers might have to tweak what they currently do to demonstrate that they’re managing their trade waste discharges appropriately.

Make reporting requirement compulsory, and explicit in the bylaw

It’s not explicitly stated in the bylaw that consented trade waste customers need to report back to us with their monitoring results. We’re amending this to make this a stated requirement under the bylaw.

Allow us to consider how costs might change in the future

Charge setting is provided for in the scope of the bylaw to allow consideration of the most equitable spread of costs between domestic and trade waste discharges.

The description of the costs that could be considered in future charge setting has been amended to be more explicit and now appropriately includes all operational activity costs associated with the provision of the wastewater activity.

These include but are not limited to the cost of conveying, treating and disposing of, or reusing trade waste and the associated costs of managing the assets, including interest and depreciation, together with monitoring and administration/overheads.

A review of the charging and cost of discharging trade waste could be considered in future with this and the better information gathered from the new classification. If this happened, it would be part of the 2020/21 annual plan process.

What are the next steps?

The consultation period has closed. Council staff have reviewed submissions and are preparing a paper to adopt the new Bylaw in 2019.
