Water and waste water

Welcome to Scotland - a Hydro Nation


Water and waste water issues are cited as the top global risk in terms of impact.

1.9 billion people rely on unsafe water - with global water demand set to rise 30% by 2030. In fact, by 2025, it has been estimated that two-thirds of the world's population could face water shortages. Water scarcity threatens public health and reduces food production.

Answering these issues demands innovative and proven technologies - and Scotland's 200 water technology companies are ready to help.

Wherever you are in the world we can help you connect with the Scottish expertise needed to address your own water and waste water challenges.
