The Council approved, in principle, the introduction of water meters and volumetric charging as a water conservation tool, as a way to avoid risks of breaching resource consents, as a way to avoid unnecessary investment in water supply infrastructure and to achieve a greater equity in what people pay for water services.

During 2011/12 Council developed the charging formula to be used based on the advice of the Charging Regime Advisory Group. The decision to proceed with water meters and volumetric chanrging was made in November 2013 and charging was introduced in July 2014. 

Purpose of the Charging Regime Advisory Group

  1. To develop and recommend a draft volumetric water charging formula for introduction in conjunction with residential water meters;
  2. To undertake on-going monitoring of the pricing and charging for water by Kāpiti Coast District Council.   


CRAG had the responsibility to develop a draft volumetric charging formula for water which can be applied to both residential and non-residential properties using the following reticulated water supply. 

CRAG was provided with technical support to gather data, explore, develop and test any charging model or formula, prior to recommendation to Council.   This will include the provision of independent external expert advice commissioned for the Group on charging systems, or any other necessary analysis.   There was opportunities for members of the community to provide ideas on charging regimes into the work programme.

Framework for Development of Volumetric Charging Formulae

The CRAG, in discussing and arriving at any advice on a draft formula worked within the following framework: 

  • water charges must provide revenue for all existing and new costs of the water service activity (Note:  this does not and cannot include any costs associated with wastewater services);
  • in finding a balance between fixed (if any) and volumetric charges, there is sufficient incentive available from volumetric changing to effect behaviour change;   
  • impacts on small and larger households,  in terms of fairness (horizontal equity) and social impacts (vertical equity) are considered and explicitly addressed;
  • the charging regime must be capable of being applied across all geographic communities on reticulated supply and all sectors (e.g. residential and commercial)
  • fairness of impacts on reasonable and high users of potable water are to be explicitly addressed 
  • that particular characteristics of the Kāpiti Coast are provided for in the design of the charging system, in particular:
  • special interest of communities in gardening;
  • large older population;
  • relatively high number of low income households;
  • retirement homes;
  • unit titles;
  • holiday homes;
  • marae


  • be capable of annual adjustments to charging to address fluctuations in consumption;
  • links to the water by-law in terms of landowner responsibilities and to the rating policy in terms of hardship provisions;
  • satisfy Council’s annual cash-flow requirements;
  • not impose unreasonable administration costs.
