Water Saving Devices
Water saving is a great way to reduce total environmental stress and carbon footprint.
Each litre of potable water produced results in ~3kgCO2 equivalent or around 1 tonne per person per year!
Likewise given the current water stress of water bodies, water saving is a simple way to reduce this water stress.
New builds in the UK are required to provide homes with lower water usage, as low as 80 lppd in some cases.
Likewise Water Neutraility makes water saving the first step in the Water neutraility heirarchy.
