What percent of water in the UK is lost to leaks in pipes as it travels?
Leaks in reservoirs, pipes and taps means that 20% of water in the UK is lost to leaks as it is piped around the country.
What two strategies immediately effect the water lost in the UK?
Fixing leaks in reservoirs, pipes and taps, and dual-flush toilets mean you can save water when flushing liquid waste.
How many water do dual-flush toilets save per flush?

What is subsidence, and what can lead to it to do with water?
Subsidence is when the ground beneath a building sinks, and too much abstraction of water can lead to subsidence of the land.
By reducing the amount of water taken out of the groundwater store and stopping pollution getting in… (conclusion sentence)
this can be a sustainable water management strategy because it means groundwater stores are able to recharge and the supply remains stable.
How is recycling water done (simple)?
Recycling water involves pumping used water from homes and industries to water treatment plants where it is filtered and treated to make it safe to use again.
What could the U-turn be for a point about recycling water?
Recycling water is very time and energy expensive, and the energy is usually generated by fossil fuels.
Recycled water is mostly used for… but it can be…
Recycled water is mostly used for irrigation, industry, flushing toilets but it can be extensively treated to make it potable.
Recycling water puts less pressure on…
groundwater supplies, rivers and lakes.
What can you use ‘grey’ water for?
