NEW PRODUCT WILL SAVE LIVES
Drinking water that looks clean may still contain bugs, which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it to destroy anything harmful. It was invented by scientist Dr Adrian Parton, who started Genera Technology five years ago. He and his employees have developed the test together with a British water company.
Andy Headland, Genera’s marketing director, recently presented the test at a conference in the USA and forecasts good American sales for it. Genera has already sold 11 of its tests at £42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government.
Genera was formed five years ago and until October last year had only five employees; it now employs 14. Mr Headland believes the company should make around £ 1.9 million by the end of the year in the UK alone.

The new product has been a commercial success in the USA.
