There are many water saving devices available to buy. The following is some information on a small selection:

• Push taps turn off after a preset period. The user pushes down on the tap head to deliver flow. The tap automatically closes off after a delay period.
• Aerators restrict the flow of water from the tap without reducing water pressure.
• Displacement devices – older toilets may use more water for flushing than necessary. A cistern insert, such as a hippo bag or sealed bottle of water, may reduce the volume of water per flush by up to 3 litres. The insert works by displacing water (the volume of the immersed object will be equal to the volume of the displaced fluid).
• A water butt is a container for collecting rainwater from your roof and downpipes (pictured). Rainwater can be used for watering indoor and outdoor plants.
