Important notices about the water supply and water restrictions in Selwyn District, including what is required of you if there is a water restriction in your area.

Temporary restrictions in place

  • NO formal restrictions due to high demand for water are currently in place for Council water supplies in the Selwyn District.
  • Council will be reviewing water use throughout summer for mandatory restrictions. If demand for water increases in light of receding water levels or reduced rainfall in the region, formal water restrictions are likely to be introduced.

Our current water use

  • Water use by Selwyn households is very high – the average household uses over 1,000 litres per day (by comparison, typical consumption for a New Zealand household is around 675 litres per day).
  • Water is not an unlimited resource and we want to encourage Selwyn households to use water in a sustainable way.
  • The best time to irrigate lawns is from 9pm to 6am, as water has the opportunity to soak into the ground and be retained there. Irrigation during daytime, during hot or Nor-West weather is wasted as a lot of water evaporates.
  • For further information on water supply and water demand, please read our Questions and Answers.

Levels of Restrictions

We have four levels of restrictions:


Level 1

  • Watering of lawns is permitted between 9am-4pm and 9pm-6am only.

  • Garden watering is permitted.

Level 2
  • Watering of lawns is permitted between 9am-4pm and 9pm-6am on alternate days only
  • Garden watering is permitted.
  • There is a requirement to decrease demand especially during peak periods.

    (Note. If your street address number is even then water on even-numbered days, if your street address number is odd then water on odd-numbered days. For example if your property number is 2, 24b or 108 you can water your lawn as needed on the 8, 10, 12 December and so on during the permitted times. If watering during the daytime we recommend choosing a cooler day to reduce evaporation.)

  • There is a requirement to decrease demand.

Level 4
