How to increase a building's water efficiency

When constructing a new build, there are a number of measures you can take to ensure the new property complies with water efficiency standards. To make sure you're saving as much water as possible, take a look at these tips:

Use water closets that meet IPC requirements

Older water closets that have a higher flow might seem cheaper, but newer models with low flow rates improve your water efficiency greatly. There's also no need to worry about blockages and clogging as although the first low flow designs suffered from this, the problem has been rectified now.

Dual flush

Having the option to flush toilets with more or less water helps to increase a building's water efficiency and allows users to have more control over their impact on the environment. Different flushes will offer varying numbers of litres in a flush, so browse the market to find the right one for you.

Restrictive aerators

When it comes to installing sinks, opting for restrictive aerators will save water. Standard 2.2 gpm sizes can be replaced with 0.5 gpm aerators to significantly reduce the amount of water that's being wasted when taps are in use.

Greywater supplies

Although not suitable for drinking, greywater can be used in toilets to reduce a building's use of the domestic water supply. If the area you're building in supports greywater use, it's a viable option to make your building more water-efficient.
