Explanatory note: This part of the Bylaw allows us to regulate the discharge of trade waste from trade premises into sewerage drains under our control. Under this part of the Bylaw, we can grant consent to occupiers allowing them to discharge trade waste. We may also set charges for trade waste discharged from any trade premises.
9.1 Introduction and purpose
This part of the bylaw covers the discharge of trade waste to North Shore City Council’s sewerage system and/or wastewater treatment plant.
This Bylaw sets out uniform requirements for contributors into the wastewater collection system of North Shore City Council and enables the Council to comply with all applicable consents required by the Resource Management Act of 1991.
The objectives of the of the bylaw are:
- To prevent the introduction of contaminants into the wastewater system which will interfere with the operation of the system or contaminate the resulting biosolids.
- To prevent the introduction of contaminants into the wastewater system, which will pass through the system, inadequately treated, into the receiving waters or the atmosphere or otherwise be incompatible with the system.
- To provide for the equitable recovery of the cost of the wastewater system.
- To protect persons who may come in contact with wastewater sludge and effluent in the course of their employment as well as protecting the general public.
This Bylaw provides for the regulation of contributors to the wastewater system through the issue of trade waste consents, which will define monitoring, and reporting requirements for North Shore City Council.

Measurement of flow shall be carried out by the occupier in accordance with BS 3680: Part 11A, BS 3680: Part 11B and BS 5728:Part 3 (refer Schedule 6).
9.11.3 Records
Records of flow and/or volume shall be available for viewing at any time by the Council, and shall be submitted to the Council at prescribed intervals.
9.11.4 Location
Meters shall be located in a position, which is readily accessible for reading and maintenance, and as close as practicable to the point of discharge.
9.11.5 Meter calibration
The occupier shall arrange for confirmation of the flow metering equipment and instrumentation by a company with appropriate accreditation in accordance with NZS 10012:Part 1 (refer Schedule 6) upon installation and at least once a year thereafter to ensure performance within ±10 % of its reading. A copy of independent certification of each calibration result shall be submitted to the Council.
9.11.6 Meter in error
Should any meter, after being calibrated, be found to register a greater or lesser discharge than the quantity of wastewater actually passed, the Council may make an adjustment in accordance with the results shown by such tests backdated for a period at the discretion of the Council but not exceeding twelve (12) months, and the occupier shall pay a greater or lesser amount according to such adjustment.
9.11.7 Where the metered water supply to a premise is used to assess the trade waste discharge the Council shall ensure that flow meters are calibrated in accordance with an appropriate calibration programme.
9.11.8 Estimating discharge
Where no meter or similar apparatus is warranted, the Council may require that a percentage of the water supplied to the premises, or other such basis as seems reasonable, be used for estimating the rate or quantity of flow for the purposes of charging.
9.11.9 Faulty meters
Should any meter be out of repair or cease to register, or be removed, the Council shall estimate the discharge for the period since the previous reading of such meter, (based on the average of the previous four billing periods charged to the occupier) and the occupier shall pay according to such estimate. Provided that when by reason of a large variation of discharge due to seasonal or other causes, the average of the previous four billing periods would be an unreasonable estimate of the discharge the Council may take into consideration other evidence for the purpose of arriving at a reasonable estimate, and the occupier shall pay according to such estimate.
9.11.10 Interference
Where a meter has been tampered with the Council (without prejudice to the other remedies available) may declare the reading void and estimate discharge as provided above.

9.13.2 Review of decisions
If any person is dissatisfied with any decision of an Authorised Officer of the Council made under this part of the bylaw, that person may, by notice delivered to the Principal Administrative Officer not later than twenty (20) working days after the decision of the Authorised Officer is served upon that person, request the Principal Administrative Officer to review any such decision.
On the receipt of such a notice, the decision of an Authorised Officer shall be suspended provided that the occupier complies with the provisions of this part of the bylaw at all times. A decision relating to the matter in the request shall be made within twenty (20) working days by the Principal Administrative Officer in accordance with the relevant provisions of this part of the bylaw. Where a decision, which is the subject of a request for a review, imposes a time limit, the time shall not begin to run until such time (if any) as the Principal Administrative Officer notifies the occupier of his or her decision.
Nothing in this clause shall affect any right of appeal under the Local Government Act.
