• Shorten your shower. Each minute you add to your shower time uses about 12 litres of water. For a household of three that extra minute costs you about $90 a year in electricity.
  • To help keep track of time, try using a shower timer. Contact us and we'll send you one for free!*
  • Measure your shower flow rate - if it is more than 11 litres per minute, consider swapping your showerhead for a water-efficient one (provides the same shower experience but uses less water).  Alternatively, for minimal cost, install a flow restrictor (available at any local DIY store). 
  • Don't just watch the shower warming up! Use a bucket in the shower to catch water as it warms up. It's easy to carry out of the house so you can keep thirsty herbs happy in summer.

*Free shower timer available to Hamilton City, Waipā District and Waitomo District residents only.

  • When running the bath put the plug in first and adjust the temperature as the tub fills.
  • Reduce the depth of your bath. The average amount of water used for a half full bath is 80 litres, compared to 140 litres for a full bath.
  • Baths typically use more water than having a shower.  However, did you know that a 10 minute shower is equivalent to a bath?  If you feel like a long soak now and again, a bath may well be a better option.    
  • Use eco-friendly products and then you can reuse your bath water on your house plants or garden.


  • Check your toilet doesn't leak. Toilet leaks are often silent. A continuously running toilet can waste more than 700 litres of water a day and is not something you can ignore.
  • Don't use your toilet as a rubbish bin. Only pee, poo and paper should be flushed, the rest should go in the bin.
  • Use the correct dual flush option (half-flush for liquid waste and a full-flush for solid waste).
  • Consider installing a toilet weight flush limiter if your toilet is pre-2005. This simple gadget gives you control of how much water is used each flush.
  • Stand a full 2 litre plastic soft drink bottle in your cistern to save water every time you flush. This can achieve savings of up to 5,000 litres per year.
  • When shopping for a new toilet, use the water efficiency labelling scheme (WELS) to help you choose. Just remember, the more stars on the WELS label, the more water efficient the toilet is.
