Types of Water Supplies

The main types of water supplies are:

  1. Community water supplies (or 'networked' supplies)

This is drinking-water that is reticulated across a property boundary from the property the water is sourced from. The water supply can be council- or community-owned. They range in size from:

  • large (for more than 10,000 people)
  • medium (for 5,001-10,000 people)
  • minor (for 501-5,000 people)
  • small (for 101-500 people)
  • neighbourhood (25-100 people)
  • rural/agricultural (where more than 75 per cent of the water can be proven as used for agriculture)

    2. Self supplies

This is drinking-water that serves only one property and is not reticulated across a property boundary. Properties include houses, eateries and wineries. Refer to the Household Water Supplies HE4602 guide [Ministry of Health PDF] 

    3. Self supplies with a community purpose

This is drinking-water that serves only one property but where that property has a community purpose – eg, a school or church.

   4. Temporary water supplies

This is drinking-water temporarily supplied at an event, or to replace a usual source in an emergency.
