Scadding, who scooped a £45.5millionEuromillions prize in 2009, was one of several Welsh lottery winners who gave up their time to scoop sludge and perform other restoration work at the Monmouthshire and Brecon Canal at Llantarnam.
The team of lottery winners was taking part in the Waterworks project-led by Torfaen Council and the Monmouthshire, Brecon and Abergavenny Canals Trust, which recently received a Heritage Lottery Fund grant of £845,500.
