People have lived alongside the River Lim, in southwest England, for centuries.

Children paddled in the water on hot summer days, sharing it with fish and birds.

Last Friday, the Lim was declared "ecologically dead". A sign warns people to stay out. The river is coated with a "brown layer" of human waste, filled with the deadly bacteria E. coliEscherichia coli is a large group of bacteria. Many are harmless, but some can cause sickness. . This was caused after 2,200 hours worth of untreated sewage split into the water.

The tragedy of the Lim is one among many. Britain's rivers have become filthy. Last year raw sewage was spilled into rivers 389,000 times, or for over 2.7m hours.¹

England's sewers send toilet water and rainwater to sewage treatment works. When the pipes are overrun, the water companies are allowed to dump it into rivers instead. 

This was meant to be an emergency measure. But it happens all the time.

People have taken note. Last year, MPs called Britain's rivers a "a chemical cocktail" of sewage, micro-plastics and slurryA mixture of water and small pieces of solid, typically manure, cement or coal. .

On Thursday, Water UKA group representing the UK water industry. chair Ruth Kelly offered an apology. Kelly said: "We're sorry about the upset and the anger from the fact that there have been overspills of untreated sewage onto beaches and into rivers over the past few years."

A new law forces water companies to cut sewage or face fines. Kelly announced that they will invest £10bn in reducing spills. New sewers are already being built.

But activists warn it will take 20 years to clean Britain's rivers under these plans. But it may be too little too late.

Water companies are responsible for about 35% of water pollution. Another 40% comes from the chemicals used in farming.² Farmers often dump chemical-filled waste into rivers. This sort of polluting is hard to stop.

Can we ever have clean water again?

Yes: The new rules are a promising start. Upgraded sewer systems should have a big effect. And public anger has reached a fever pitch that might lead to further changes. Change is slow but sure.

No: The speed and scale with which we have despoiled our waterways is incredible. Everyone needs to join to force a change. But with so many causes, this will take a miracle.

Or... The real question is whether we will have any water. The global demand for freshwater is increasing. But supply is going down due to global warming. Before too long, we might be without freshwater at all.
