I'm Elizabeth Hotson. Welcome to Business Daily from the BBC. On today's programme, I'll be looking at some ingenious solutions to some very pressing water-related problems.

From a Victorian feat of spectacular engineering. Building this sewer system must have saved the lives of tens of thousands of Londoners.

To a way of stopping water crime.

They know where some of the water pipes are,

so they're able to dig up and connect themselves to the system,

and now they get few water, which is basically stealing water.

And a quick and cheap test for water quality.

It's safe to drink just or no, and it takes like three minutes to get the results.

You can do a very large-scale monitoring with field tools like this.

That's all in Business Daily from the BBC.

What would you say is the most valuable commodity on the planet?

Gold, diamonds, how about water?

You can live without fancy jewellery, but life would literally be nothing without H2O.

It's quantity, whether you have too little or too much,

and how clean it is, a fundamental to human existence.

And if you follow the news, you'll have heard dozens of reports about water this year alone,

whether it's drought in southern Europe or hurricanes in North America?

We're keeping a close eye on Hurricane Milton, which is getting stronger as it heads toward landfall in Florida on Wednesday. Meanwhile, thousands in the southeast are still reeling

The Catalan government in the northeast of Spain has declared a state of emergency

in response to a record-breaking drought.

While there's also flooding in Central Europe.
