Chapter 17 - Trade Waste

The Council is aware of instances where the discharge of trade waste to the Council’s wastewater systems has or can damage those systems.

The operation of the bylaw over the past five years has shown it to be an effective and acceptable means to protect its wastewater and stormwater systems from inappropriate and potentially damaging discharges of trade waste.

Key changes proposed are:

• Clarification of relationship with other Acts and definition of area[geographic];
• Update of 10 key definitions against NZ Std 2004;
• Inclusion of new trades and clarification that  listed trade activities are not exhaustive;
• Specify  accidents and reporting and include infringement offences otherwise not eligible to be used;
• Include a section to manage ‘tankered wastes’;
• Requirement for the dechlorination of potable water before discharge into the wastewater network;
• Decision review, appeal to the Council to be final;
• Various wording clarification  and numbering corrections and to make forms ‘pro forma’;
• Increase mercury levels to an achievable limit for dentists, without adverse effect and the removal of aluminium from the list of controlled substances;
• Remove outdated charging levels and enable charging on a catchment or other basis.
• Provide for Watercare Services Ltd., [WSL] charging regime to apply where wastewater is discharged into WSL networks.
