The reticulated water supply is provided by a network of intake structures, reservoir storage, pump stations and an extensive underground pipe network. This water is utilised by rural, urban and commercial users for domestic and business purposes. 

Registered water carriers

Rain Tanks 

All new premises in the Waikato District are required to have a rain tank under the Water Supply Bylaw.

This helps create more sustainable water supplies and encourages rainwater storage for non-drinking use.

A rain tank is required for all new premises that will:

  • be more than 30m2; and
  • connect to a Council water supply; and
  • have facilities that use water such as a toilet/laundry that the roof water could be used for.

How to maintain water quality

Water quality in improperly maintained tanks and roof catchment systems is a risk to public health. Preventative measures and corrective actions for safe rainwater harvesting include:

  • Keep roof catchments clean of moss, lichen, debris and leaves
  • Keep roof catchments clear of overhanging vegetation, branches provide roosting points for birds and provide access for animals, such as rodents and possums
  • If appropriate install gutter guards or screens as well
  • Install screened down pipe rainheads or other debris protection devices on each down pipe - Recommended screen mesh size is 4-6 mm, these should be self-cleaning devices
  • Install a first foul flush diverter to prevent contaminated water entering the tank. These should have automated diversion and drainage systems
  • In the event of any weed/chemical spraying in an adjacent location, advise the contractor that the roof is used for collecting drinking water. There should not be any overspray. Organochlorine pesticides should not be used
  • Prevent access by small animals to the rainwater tanks by screening all inlets and overflows, access hatches should be left closed
  • Inspect tanks annually - Have a professional clean the tanks
  • If tank contamination is apparent the water should be chemically disinfected and boiled before the water is used for consumption
