The recent and prolonged dry spell has brought water scarcity in the UK into sharp focus. Several water companies in the south of England have triggered restrictions, including hosepipe bans.
On 12th August the Environment Agency declared drought in eight out of 14 water areas. Unfortunately, this is likely to be the future. We can’t just pray for rain. We need to regenerate river catchments and plan for the climate crisis.
Robyn Shaw, Assistant Education and Engagement Officer at the South East Rivers Trust, looks at the factors around water scarcity and introduces our Water Saving Tips page, which emphasises that the issue is one we must all take responsibility for and think about all year round.
The South East Rivers Trust has been working with Sutton Council to deliver a SuDS in Schools project in Carshalton. Delivering a sustainable drainage systems (SuDS) project has been a new and valuable experience for the Trust.
By 2050, the South East of England will need to find at least an additional one billion litres of water per day to meet demand in the region. That is about a fifth of the water used in the region today, and equivalent to the water use of seven million people per day. Demand for water will exceed supply by 2030.
This is because of a combination of different factors. Some of it is because of the expected growth in population (even if personal water consumption is reduced). Some because water companies are trying to ensure that they have enough water available to continue supply even during more significant drought periods.
Finally, climate change will affect when water is available, and how much. Unsustainable abstractions need to be reduced in order to avoid our rivers and wetlands being damaged beyond repair.
