After overseeing last year's inaugural edition in his native South Africa, former international pace bowler Elworthy has been retained to oversee the 2009 event by English cricket chiefs.
Next year's competition will break new ground by having the women's Twenty20 World Cup run alongside the competition with the semi-finals and the final for both sexes taking place on the same ground and on the same ticket.
"It was a new youthful inclusive tournament in 2007," Elworthy said at the launch of the 2009 tournament at The Oval here Tuesday.
He added: "The inclusion of the women's event is an historic moment in terms of the women's game."
England women's captain Charlotte Edwards said: "This is a great chance to showcase women's cricket.
"In January we experienced playing a women's game before a men's game at the MCG (Melbourne Cricket Ground) and we're hoping for more of same."
Matches in the men's tournament will take place at Lord's, The Oval and Trent Bridge with the final at Lord's on June 21 marking the culmination of 42 matches in 15 days.
International Cricket Council (ICC) officials have also moved to ensure home fans are not priced out of the event after many tickets at the 2007 World Cup in the Caribbean proved beyond the reach of ordinary West Indian supporters.
Under-16s will be able to watch the final for as little as 10 pounds (20 dollars while the most expensive adult ticket is 90 pounds (180 dollars).
The 10 Test playing nations plus two associates or junior nations will be split into four groups with the top two going through to the Super Eights.
England begin the tournament against an as yet unknown associate side, to be determined by the winners and runners-up of a tournament in Belfast in August, at Lord's on June 5, where the final takes place on June 21.
"India are the defending champions and captain Mahendra Dhoni said: "It would be a dream to lift the trophy at Lord's."
The semi-finals are at Trent Bridge and The Oval respectively on June 18 and 19 with the final taking place. Meanwhile the bulk of the women's matches before the last four will be played at Somerset's headquarters in Taunton, south-west England.
