Buller District Council

Sewerage

The Buller District Council operates three sewage treatment facilities. These are located in:

  • Westport – Contact Stabilisation Plant
  • Reefton – Oxidation Ponds (Primary, Secondary and Tertiary Treatment)
  • Little Wanganui – Oxidation Ponds (Primary Treatment only)

These are all operated by WestReef Services Ltd under supervision from Council staff. These are all monitored frequently to ensure that all effluent leaving the facilities complies with their respective Resource Consents and is sufficiently treated prior to entering their receiving waterways.

Stormwater Infiltration – Westport

Prior to the commissioning of the Westport Wastewater Treatment Plant foul sewage and stormwater were often discharged to the same pipe which was then discharged to the receiving waterways. This stormwater infiltration now causes significant loadings on the plants during wet weather, with sometimes as much as ten times more flow entering the plants than during normal dry weather flow.

As some areas of Westport experience a considerable backup of sewage/stormwater during moderate to heavy rainfall, Council are investigating where stormwater infiltration can be removed. This may include the separation of stormwater at various residential properties.

Council would appreciate any efforts by property owners to separate stormwater from foul sewage lines on their properties, particularly in areas where problems exist. If you require advice please contact Councils Operations Division on 03 788 9111.

Orowaiti Sewerage Scheme

The Orowaiti Sewerage project has been operable since February 2009 with approximately 160 properties connected so far. Council has invoiced the residents $3,000 plus GST and this sum can be paid in one or more instalments over a three year period until 30 June 2012.

The debt is registered against the property owner as at 1 July 2009, therefore if your property is sold (or title is otherwise transferred) before the sewerage connection fee is paid in full, it is your responsibility as the liable debtor to either:

  • Settle the debt with Council; or
  • Make suitable arrangements to transfer the debt to the new owner and to advise Council accordingly.

As the sewerage system is now operational ratepayers are liable to pay the targeted sewerage rate even if not connected.

Property owners are required to connect to the reticulation within this three year period up to 30 June 2012. A building consent is required to carry out drainlaying work on your property. Drainlaying work must be carried out by a registered drainlayer. Building consents can be lodged with Council at any time, they need to include an onsite drainage plan indicating where the new drainage lines will be located.

Once connected to the reticulation, the septic tank needs to be cleaned out by an suitably qualified contractor, and the tank filled with an appropriate material.

The new sewerage system is only designed to accept sewerage, therefore stormwater needs to be separated from any existing pipework and disposed of separately. It may be possible to then use the redundant septic tank as a soak hole for stormwater disposal if required.

A code compliance certificate verifying that all building work has been completed will not be issued until the septic tank has been emptied and subsequently filled.

Westport wastewater treatment

The Westport wastewater treatment plant was opened on Saturday 19 May 2007. It is a Contact Stabilisation Plant which uses an aerobic process to treat Westport’s raw sewage.
