It is quite easy to reduce the flushing volume as there are several solutions available on the market. You could try reducing the ball-valve setting, using displacement devices such as water saving bags, purchasing half dual setting toilets at your next refit, or even having toilets which flush for however long a person keeps a button depressed for. Naturally also check your bowl for internal leaks on a regular basis - these can waste tons of water a year if undetected. 

Water saving bags

These bags are placed in the flushing cistern and displace a fixed amount of water, decreasing the flush volume. Different sizes of bag area available to fit different sizes of cisterns. Prices range from €1.50 to €2.00 per unit.

Dual flush toilets

These toilets have a half flush mode for liquid waste, and full flush mode for solid waste. Coupled with an awareness raising programme amongst users, they can be an effective water saving fixture.

Push button line flushing

Push buttons can normally be adjusted by removing the cap and screwing the spring into its minimum setting. This releases the smallest amount of water permitted by the producer.

Manual flush control

Some toilets allow for operator-controlled flushing where the toilet flushes water for as long as a button (or a flap) is pushed. This allows the user to adjust the flush volume according to the nature of the waste being discharged, as is considered to be a very water-efficient flushing device.  

In-bowl leakages

Warning – severe water loss can easily be prevented by monitoring in-bowl leakages. These are normally caused by a faulty flushing mechanism and result in a trickle of water leaking from the flushing cistern into the bowl. This tiny trickle leaks water 24 hours a day, 7 days a week, for however long it takes to fix it. Spotting this leak is easy if one looks for it; cleaning or maintenance personnel can report it, alternatively maintenance personnel can insert dyes into the flushing cisterns and check the bowls a few hours later for colour. Fixing the leak normally involves replacing the faulty flushing mechanisms.
