Taps
(Kg of CO2)
(based on 40 people's use)
Air is mixed into the water under pressure, reducing the amount of water flowing through the tap whilst providing the impression that there is more water flowing.
Restricts the flow of water through the pipes leading up to the tap. Fitting requires a trained plumber, but it is maintenance free.
Reduces tap water consumption by approximately 40%. Saves water and, if used on hot water connections, energy costs as well.
A small rubber circle used to seal the mechanism within a tap – often replacing this part can stop a tap dripping.
The tap turns on when you apply pressure and turns off after a few seconds when you release the pressure.
A small motion detector turns the tap on or off. These have benefits over push taps in that push taps will always give the set amount, even where it is not necessarily required, and push taps may also stick as a result of scale build up.
Showers
(Kg of CO2)
(based on 40 people's use)
To automatically regulate how long people spend in showers you could install a timer or push operated mechanism. This device prevents showers from being run continuously and can be easily retrofitted onto existing showers.
Showers could be fitted with a water-saving showerhead, which works either by introducing air or creating finer drops. They are able to give the feel of a more powerful shower at a flow rate of 8 litres per minute.

Three buckets – between 10,000 and 100,000 litres
Four buckets – over 100,000 litres
One balloon – below 0.5 kg
Two balloons – between 0.5 and 5 kg
Three balloons – between 5 and 50 kg
