Time to Flush Our Water Wastage Down the Drain
Byline: By ROBIN TURNER Western Mail
Families could soon be using sea water to flush the toilet as part of an innovation aimed at solving the world's water crisis. Welsh scientists have created a system which draws on sea water rather than fresh water for any household needs that do not require drinking or washing water.
Tests on the project, which could prove invaluable for highly populated areas with little rainfall in parts of Africa, Asia and the Middle East, are under way in Gorseinon, Swansea.
It could also prove important for Wales - a nation known for its wet weather - as the sea water system can save up to 30% on water bills.
Poseidon Water Ltd, a spin-off company from Cardiff University, is already in talks with German manufacturers to provide equipment for the process.
Rod Howells, Poseidon's business development manager, said sought-after homes on Swansea waterfront's SA1 development would be ideal candidates for the sea water flush.
Mr Howells said, 'The SA1 development, where there will be more than 1,000 new homes and a lot of businesses, will use a lot of fresh water.
'It is a peninsula going out to sea so it would be ripe for using the system. It would not only cut bills for people living and working there, it would leave a lot more fresh water for the rest of us.
'Although Wales is a water rich, country in comparison to most, we should never waste fresh water on things like toilet flushing. Flushing typically uses 30% of a home's fresh water so changing to a sea water system means that water can be saved for other applications.
'The system is much cheaper to run and maintain and is more flexible than a desalination system because it can be used on a much smaller scale.'
With 70% of the world's population living within 50km of the coast, the waste water treatment system has the potential to tackle the growing problem of water shortages.
Initially, the company is targeting environmentally sensitive coastal sites such as holiday resort islands. …
