Using Water Wisely

Water Saving Tips

Save Water at Home

There are lots of ways to save water around the home, as much of the water we use is wasted. By making a few small changes in your habits you can help save water, not by going short or without, but by cutting out waste and unnecessary use.

Check for leaks
  • Leaking taps, toilets, showerheads and other water-using devices are major wasters of water. Just one leaking tap can waste 2,000 litres per month and increase your water bill unnecessarily.
  • Most leaks are easy to detect and easy to repair with basic know-how and the right tools.

 Tips around the home
  • Sing shorter songs in the shower: every minute that you don’t spend in the shower saves you seven litres of water. Reduce your shower by one minute, and you’ll save about 2,500 litres of water a year.
  • Turn off the tap when brushing teeth or shaving:  a running tap wastes 10 litres per minute.
  • Washing vegetables: plug that sink when you’re preparing vegetables. It’ll save you up to 10 litres per minute.
  • No half measures in the kitchen or laundry: a full load of dishes or laundry uses less water and power than two half loads.
  • A scrape will do! Today’s modern dishwashers and detergent mean there’s no need to pre-rinse, just scrape and pop the dishes in the machine – give it a go, you might be surprised by the results.
Water saving devices

There are many water saving devices you can buy that reduce your water use. These include aerators (mix air with water), flow regulators (to reduce the flow of water), dual flush toilets and cistern displacement devices (‘gizmos’) for single flush toilets. Many devices aren’t very expensive.

Water wise appliances – shop with the stars!

You can save water and a lot of money in the long run by choosing water wise appliances.To help you choose the most water efficient appliances a water efficiency labelling scheme (WELS) has being introduced. The more stars on the label the more water efficient the appliance. So if you’re replacing an old washing machine or toilet choose models with four stars or more.

In the garden

Being water wise in the garden and outside means we reduce the amount of high quality drinking water used on lawns, plants and pavements. Sprinklers are the biggest cause of unnecessary water useage as they water where not needed and often over water.

Water wise tips in the garden and outside

It’s a lawn not a lake! Even at the height of summer a weekly drink is all your lawn needs. Super smart tip: If the grass springs back when you walk on it, there’s no need to water.

  • Install a rain barrel: a rain barrel is a great way to cheer up your plants and keep your water bill down.
  • Use a bucket to wash your car. This uses up to 125 litres less water than a hosepipe does.
  • Simple mulch for your garden reduces the water that evaporates by up to 70 per cent and means less time spent watering.
  • Water in the early morning or evening to reduce water lost to evaporation.
  • Sweep paths and drive ways instead of washing them.
  • Use a watering can or a hose with a hand-held trigger to minimise wastage and direct water only where needed.
Save Water at Work

Water is a valuable resource yet all too often we take it for granted. Whether your business is large or small it can benefit greatly from using water wisely.
Benefits of saving water at work:
Save your business money
Saving water will have a direct and positive impact on your water and wastewater bill.

By not using as much hot water you’ll also be able to reduce the energy needed to heat water and therefore reduce your electricity/gas bill.

Be seen as environmentally friendly

Demonstrate to customers the importance your business places on caring for natural resources and the environment.

Water and wastewater treatment uses energy – so by saving water you’ll reduce your carbon footprint.

Using water wisely is part of plan for a sustainable future and demonstrates corporate responsibility.

Five tips for saving water at work
  1.  Install dual flush toilets A full toilet flush sends 12 litres of water down the drain. A dual flush toilet can use as little as three litres in a flush. If you have a single flush toilet, you could install a cistern displacement device, often called a “gizmo”. Depending on the size of the cistern, these devices can save one to two litres each time the toilet is flushed. However do check the manufacturer’s instructions to make sure the device is suitable for your toilet.
  2. Repair dripping taps Fixing these could save as much as 2,000 litres of water a month. In most instances all that’s required is a new washer.
  3. Install urinal controls On average, an unmanaged cistern flushes four times an hour 24 hours a day. Sensor controlled urinals can reduce the amount of water used as the urinal only flushes after use.
  4.  Measure and monitor Use meter reads to compare your water use so that you can identify any unusual patterns.
  5.  Awareness: Make your staff aware of how they can save water


Flushing your drinking water tap.

Some plumbing fittings have the potential to allow minute traces of metals to accumulate in water standing in the fittings for several hours.

Although the health risk is small, the Ministry of Health recommends that you flush a large glass of water from your drinking water tap each morning before use to remove any metals that may have dissolved from the plumbing fittings.

We recommend this simple precaution for all households, including those on public and private water supplies.
