Zurich's Try for Charity campaign – now in its third season – ensures that each time a player scores three or more tries during a Zurich Premiership match, six selected charities each receive £500.
Zurich have now upped their contribution by including the Nick Duncombe Memorial Fund to the list of regular beneficiaries, which comprises the Andy Blyth Benefit Trust, The Wooden Spoon Society, The Richard Langhorn Trust, The Jarrod Cunningham Fund and the Wavell Wakefield Youth Sports Trust.
The new trust was set up in memory of Nick Duncombe, the 21-year-old England and Harlequins scrum-half who died of blood poisoning in February of this year.
All the charities are set to benefit from what is shaping up to be a try-heavy season – Waters' achievement is already the third hat-trick of the Zurich Premiership and follows Newcastle Falcon Tom May's effort against Gloucester and Ugo Monye's trio for the NEC Harlequins against the Rotherham Titans.
Last season there were four hat-tricks – scored by Marcel Garvey and James Forrester of Gloucester, Simon Shaw of London Wasps and Brendon Daniel of Bristol Shoguns.
In the 2000/01 season there were nine hat-tricks scored, bringing the total amount donated by Zurich to around £40,000 over the last three season.
