Smart Water use in the home

August 31, 2009

We were provided handouts on A quick and easy Smart water use check up to see how we can save water, power and money!

I am providing below a short synopsis of tips that I think are great and easy to measure.

Get a pen and paper and record the results as you work around your home.

1. TAPS

If any of the taps in your kitchen, bathroom or laundry are:

  • Individual hot and cold taps mounted on the counter top or
  • Single lever (mixer) faucet/tap or
  • Individual taps with a combined spout

To check the flow rate – do this:

a. Turn the water on and run it at your normal flow

b. Place a container under and tap and collect water for 10 seconds

c. Measure the volume of water collected (e.g. pour into a measuring cup)

d. Multiply the volume x 6 to determine flow rates in litres per minute (l/min)

If the flow rate is more than 12l/min on any tap, consider installing an aerator or flow restrictor to reduce to 9l/min ir less – a minimum 25% reduction.

2. TOILETS

Check toilet type. Is the toilet:

  • Single Flush orDual flush (can’t be imrpoved)

If the toilet is single flush model:

a. Take the top off the tank behind the toilet

b. Locate the centre post with washes that keeps the water in the tank

c.Flush the toilet and watch the action of the lever arms and centre post.

To reduce the volume of water used during each flush. you can:

a. Adjust the lever arm so that the float stops the tank refilling at a lower level – this gives a modest reduction in water us or

b. Install a cistern weight, hanging it over the centre post – this can reduce water use by as much as 60% every flush!!! To function properly, hold the flush lever down until the bowl is clear then release it. when you do this. the weight forces the washer to close and prevents any more water escaping.

3. SHOWER

If the shower is a :

  • Standard/wall mount shower or
  • Slide and hose type

Check the flow rate. To do this:

a. Turn the water on and run it at your normal flow.

b. Place a container (e.g. a pail) under the shower flow and collect water for 10 seconds.

c. Measure the colume of water collected (e.g. pour into a standard size container)

d. Multiply the volume x 6 to determine flow rate in litres per minute.

If the flow rate is more than 18l/min, you can install a low-flow showerhead or flow restrictor to reduce it to 9 or 12l/min – this provides a minimum 33% reduction in water use.

Start saving water, power and money!

Save even more money by reducing your shower time. Go for the famous ‘four-minute’ shower (I need to practice this when I am preaching this) 😛
