Developers must install rainwater toilets when building new homes to stop river pollution, campaigners have said.
Britain’s Victorian water system is already struggling to cope, with sewer systems frequently overflowing, making England’s rivers the dirtiest in Europe.
Now there are calls for tougher restrictions on developers, limiting their ability to connect new homes to sewers and requiring new homes to meet water efficiency standards.
Water companies can dump raw sewage in rivers and the sea when rainfall mixed with waste water from households overloads the system, something which is only supposed to happen on rare occasions but in practice happened 400,000 times last year.
Campaigners said measures such as reusing rainfall to flush toilets as standard, reducing the volume of water going into sewers, would stop the system becoming overloaded.
The system works by capturing rainwater and filtering it into a tank where it is kept at a suitable temperature to avoid bacteria. The water is then pumped through the plumbing system when a toilet is flushed.
By diverting rainwater from sewer systems into household plumbing, sewers become less overwhelmed, decreasing the likelihood of river pollution.
Bit Heath Robinson. Every house now has to have an additional system.
Why not just build out the central sewer system a bit more?
And wouldn’t it be nice to see the proper costings on this?
BTW, doesn’t the water company own all the rainfall anyway?
