Reducing Pollution from Council-Owned Assets

Sewage Discharges

Sewage Treatment System Upgrades

Upgrades are either in process or imminent at Tapawera, Murchison, Motueka, Takaka and Collingwood. The Collingwood sewage treatment plant, which currently consists of an oxidation pond and artificial wetlands, now has an ultraviolet treatment system.

Sewerage Reticulation Projects

Several townships have had reticulated sewerage installed in the last five years, including St Arnaud, Richmond (Hill Street), Motueka, Tapu Bay-Kaiteriteri and Takaka/Pohara.

Stormwater-Sewer Separations

A programme of separation of stormwater and upsizing of sewerage reticulation systems is ongoing.

Monitoring Sewage Discharges

Monitoring for each discharge is specified as part of the resource consent to discharge from each wastewater treatment plant. This monitoring is tailored to the scale, nature, intensity of the discharge and the receiving environment for each set of discharges. Council’s compliance monitoring officers are responsible for auditing the consent monitoring data and information.

Stormwater Discharges

Council is looking to improve the quality of water from their stormwater network to streams in Richmond and Motueka. As part of this process investigations have been undertaken to assess the current impact of the discharges.
