Water pressure – cities at risk

The danger of Cape Town running out of water is severe enough, but our disrespect for water is far wider.

According to a recent BBC News story:

• 1 in 4 of the world’s 500 biggest cities face water stress.
• 1 billion people have inadequate access to water.
• 2.7 billion people face shortages for at least 1 month a year.
• Fresh water demand will exceed global supply by 40% as early as 2030.

The 12 major cities most at risk were reported as Cape Town, Sao Paulo, Bangalore, Beijing, Cairo, Jakarta, Moscow, Istanbul, Mexico City, London, Tokyo and Miami. So no region escapes.

Nor is the Cape Town situation unique. Sao Paulo’s main reservoir dropped to less than 4% of capacity in 2015. Istanbul’s fell below 30% in 2014. Moreover:

• Bangalore loses over 50% of its drinking water through leakage.
• 40% of Beijing’s surface water is unfit even for agriculture or industry.
• 40% of Jakarta is below sea level because of illegal wells.
• London anticipates serious shortages by 2040.

There is certainly enough water. We just don’t use it wisely.

    Water scarcity is a huge global problem.
    A little known but globally patented Australian invention may help solve ( ie 1-3 Trillion litres of water) much of this problem.
    Inside fruit and vegetables is found the most hydrating water in the world. In a global first, Botanical Water Technologies has developed a way to capture, retain and bottle this water. The technology can be used as part of existing infrastructure and the cost of water is at a fraction of other sources such as aquafer etc. The process has been validated via a retail product manufactured in Australia ( http://www.aquabotanical.com.au) but can also be licenced by other beverage manufacturers who are looking for a pure source of operations or drinking water.

    Only nature could improve on something as pure as water…
