2009 - 2012

The Wastewater Asset Management Plan (AMP) produced for the public wastewater assets owned and managed by the Nelson City Council provides a 12 year outlook starting in July 2009 and is updated every three years. The AMP demonstrates how Nelson City’s goal, strategic targets and delivering the agreed Levels of Service (LOS), will be achieved through effective, sustainable management of the wastewater assets.

The replacement value of the wastewater infrastructural assets is $144M and accounts for 13% of the total Council infrastructural assets replacement value (2008).

Nelson's wastewater system

Council provides wastewater services from Glenduan in the north to Stoke in the south with 19,208 connected properties (2008).  Sewage from Stoke and Tahunanui is treated at the Nelson Regional Sewerage Business Unit (NRSBU) Treatment Plant on Bell Island.  Fish processing water from Sealord Group Ltd is screened and discharged beyond the Boulder Bank into Tasman Bay.  Effluent from the remainder of the city is treated at the Nelson North Wastewater Treatment Plant (WWTP) at Wakapuaka.

Goal of the wastewater activity

To provide a wastewater system to Nelson City that is capable of collecting and treating wastewater in an efficient, safe and sustainable way whilst ensuring that the cultural ecological and recreational values of waterways and the marine environment are recognised and enhanced.

Rationale for Council’s involvement
Legislative requirements

Council has statutory obligations to provide wastewater services – Local Government Act 2002 requires Council to continue to provide wastewater services recognising the requirement to take a sustainable development approach that takes into account:

  • the social, economic and cultural wellbeing of people and communities; and
  • the need to maintain and enhance the quality of the environment; and
  • the reasonably foreseeable needs of future generations
Public Health and Safety

Adequate treatment of sewage is essential for community well being - The Health Act 1956 places an obligation on Council to improve, promote and protect public health within the District.

Reliable provision

Human health, tourism and industry, in particular, rely on the reliable provision of this service - The Local Government Act 1974 provides the authority for the Council to own and operate the Wastewater service.
