A NORTH Cotswolds woman is in line for a national environmental prize for her simple invention that helps people re-use their bath water.

Louise Angus of Upper Slaughter created Watergreen, a simple siphon to enable used bath water to be pumped onto flower beds, with her business partner Antonia Lord during the hosepipe ban of 2006.

Watergreen is now a finalist in the Waterwise innovation section of the Future Friendly Awards being presented at the Banqueting House in Whitehall by Sir Trevor McDonald this evening. (Thursday, March 6) If she wins, Louise, who set up and ran MTV's sales and marketing operation for 10 years, will win a £10,000 bursary towards the patent application for her invention.

"We are all using a lot more water. The UK has less water per capita than the Sudan. In the south east we simply don't have enough water to go round," said Louise.

"If everybody made a few behavioural changes we could really make a difference," she added.

Since it was launched, more than 10,000 Watergreens have been sold online at a cost of £19.99. Further information is available on www.watergreen.com
