Masterton District Council’s water services include drinking water, wastewater and stormwater.

We’re committed to managing our water demand to help preserve and enhance our district’s natural environment. Our water usage has a direct impact on our local rivers; the more water we use, the less that is flowing in our rivers.

We’ve worked with the Greater Wellington Regional Council to better understand how we can balance our water consumption while preserving the health of our rivers. A key element is limiting the amount of water we use during our driest periods.

Over summer there may be some days when you’re asked not to water your garden. When things get a bit dry we need to place priority on water needed for drinking and sanitation –  our gardens need to become less of a priority in these times.

To keep up to date with current restrictions over summer keep coming back to our website, visit our Facebook page, pick up Saturday’s Wairarapa Times Age or listen to the local radio station.

Do your part, be water smart

We all need to play our part in conserving water. To explore ways to save water around your home check out the Smarter Homes website or download our water conservation guide (PDF, 891KB).

You can also try some of these tips to help you save water at home:



  • Water your garden before 7am or after 9pm.
  • Water your garden with a handheld hose only.
  • Most gardens do well, being watered every other day at most.
  • Water your garden at cooler, less windy times of the day to ensure your plants retain the water they need.
  • Set your lawn mower to leave grass slightly longer. Short grass dries out sooner.  


  • Turn off the tap when cleaning your teeth or shaving – you could save 10 litres of water a minute.
  • Reduce your shower time to four minutes or less.
  • Install water-saving shower heads or flow restrictors.
  • Use the half flush on your toilet.


  • Wait until you have a full load before starting your dishwasher. When possible, use the eco-setting.
  • Avoid rinsing dishes.


  • Wait until you have a full load before starting your washing machine, or use the partial load settings.


  • Use a broom to sweep your driveway rather than hosing it clean.
  • Wash your car with a bucket of water on the lawn and you’ll water your lawn at the same time.
