Nelson City Council is currently taking submissions on a proposed new wastewater bylaw.

You could be affected by the proposed wastewater bylaw out for public consultation.

The proposed Wastewater Bylaw clarifies what is allowed to be discharged from spas and swimming pools, and also from grease, silt, and oil traps.

The proposed Bylaw means that you can only discharge backwash or empty your spa or swimming pool into the sewer if the water has a residual chlorine level of less than 0.5 parts per million (ppm). 

If the chlorine level is below 0.5ppm you can empty your pool without prior approval to the wastewater network if you follow the following guidelines:
  • It is done between 8pm and 7am
  • There has been no rain in the previous three days
  • The flow rate does not exceed 2l/s.

If the Bylaw is approved, then you will need to contact Council if you can’t meet those guidelines.

If the discharge is chemically imbalanced, including pH, you will also need to contact Council to ensure there are no additional requirements, and to confirm the discharge process.

This Bylaw change also aligns with the Tasman District Council Wastewater Bylaw as far as practicable.

We are proposing changes to the Water Supply Bylaw too.

The changes being proposed to the existing Water Supply Bylaw reflect the new requirements of the National Environmental Standards for Sources of Human Drinking Water. 

These changes will also align the new Bylaw with the Nelson Tasman Land Development Manual 2019 and the new Tasman District Council Water Supply Bylaw as far as practicable.

Water Source Protection Zones are proposed and activities that are allowed within each zone will be controlled. 

The nature of those approved activities will depend on the risk they present to the water supply. High risk activities will be prohibited from areas close to the intakes for the raw water supply.

The deadline for submissions on these two bylaws is Tuesday 27 April.

Nelson City Council, PO Box 645, Nelson 7040

Submissions can be hand-delivered to Nelson City Council, Civic House, 110 Trafalgar Street, Nelson or to any Nelson public library.
