Water Saving

OK so I think we probably all understand that water saving is very important.  Maybe not an instant priority for us in Scotland as we seem to have plenty of the blummin’ stuff but let’s face it we are part of a global community and there are countless millions of folk out there for whom clean water is not freely available.  That means it is our duty – in my opinion – to make every effort to save this precious resource.

clean drinking water should not be taken for granted - water saving is our duty

Now water saving happens to save money for many of my clients so there is some synchronicity here with my energy saving work.

Where do business use water?

How long is a piece of string?  The uses for water are so many – however, there are some essential common areas that we can investigate and see where useful / valuable water savings can be achieved.


The humble WC nowadays comes with a dual flush so you can save water by flushing according to the job in hand shall we say – for politeness.  However I still find many single flush WCs during my site surveys and many of these are attached to cisterns that exceed water bye-laws by some serious margins – only last week I surveyed a building with 13L and 15L WC cisterns and no mechanism to reduce flush volume.

So what can you do?  Water saving in WCs is simple and cheap.  Use a “hippo”.

The WC Hippo - water saving at it's simplest and cheapest

The humble hippo – which costs around £5 – sits in your cistern and holds back it’s own volume every time you flush.  How simple and elegant is that.  You’ll probably even comply with the bye-laws now!

If your toilets have big cisterns fit these right now – please.

Bathroom Taps

Flow rates through bathroom taps vary massively and the waste of water associated with just washing your hands can be very significant. Water saving can be very simple.

I can’t get my head around this but I am sure you will have walked into a bathroom many times and found that someone has just left a tap running – deliberate of merely thoughtless doesn’t matter.

End result is a waste of water.  Solution – percussion taps that spring closed after a set period of flow – passive infra red sensor taps – bathroom police with heavy blunt sticks – whatever works.

Gent’s Urinals

The urinal – sorry Ladies but I need to discuss this – frequently responsible for huge waste of water because they can be left to flush 24/7 – but hey the toilets are probably not open or occupied 24/7.

Water saving in urinals is nothing new.

A battery operated PIR sensor to control a valve supplying the cistern set on a simple timer to ensure that the maximum number of flushes per hour meets the local bye-laws.

These controls usually pay for themselves within 1 year.
