The apartment I live in is located on Anzac
Parade, and has been used for over ten years. Since most equipment and
furniture are quite old, plenty of unsustainable issues take place at home. For
example, we attempt to close the taps every time we finish using water, but
leaks still happen.
One or two drops may not seem like much at
first glance, but imagine, a large deal of water could be wasted over a long
period of time. According to the institution of Sydney-sustainable Living, one
leaking tap can waste up to 3L in an hour, that is 2000L in a month. It is
necessary to fix leaking taps or replace washers as soon as taps/shower heads
begin to drip. Moreover, similar issues could happen in the toilet. Placing a
sheet of dry paper at the back of the bowl could be a quick way to find out
whether there is a leak. Fortunately, in my bathroom, the paper remains dry
between flushes, which indicates the toilet does not drip.
On the website hunterwater.com, water usage
in each household (including waste water) could be calculated, in accordance
with your daily activities. In my calculation, the total amount of water used
annually is approximately 339 kL, which indicates 232L water is used by each
member per day. The amount is below the average usage (300L/day), but it is
only because we do not have gardens and cars. Except the 500L water waste per
week, caused by dripping tap, inefficient shower is another problem. On
average, more than 25% of household water use is for showering. The standard
shower equipped in my apartment rose supplies up to 20L every minute. However,
if a low flow shower is installed, only 9L or less water will be used per
minute. In addition, an 8-minute shower for each member of my household might
be too long. Hope we could try to shorten it to 4 minutes, as recommended. It
could not only save water, but save on the energy cost associated with heating
water.
In the next blog, I would discuss the WELS
Star Rating Scheme.
