The semi-finals, third-place play-off and final will be staged at the Twickenham Stoop.
"There are three games in a week - and it usually takes me a week to recover from one match these days," said Evans, who helped Wales to their first Triple Crown in this year's Six Nations.
"It's going to be tough, but we have to fit the tournament around our jobs.
"There will be injuries and the strength in depth needs to show. We are fielding three new caps against Sweden this weekend, that will help the development."
New Zealand speak for themselves, they're the world champions. But England beat them - and we beat England
Having recovered from the disappointment of seeing the draw for the competition, Evans acknowledged that - New Zealand aside - the southern hemisphere challenge is not as formidable as in the men's game.
"South Africa are building and improving and had a recent draw with France," said Evans.
"We don't know so much about Australia as we see less of them, but they won the World Cup Sevens in Dubai.
"New Zealand speak for themselves, they're the world champions.
"But England beat them - and we beat England.
"I was glad when I looked closer at the draw and saw that we are playing New Zealand in the third pool game.
"They looked tired when they lost to England [10-3 at Twickenham on Saturday]. They are not used to playing as regularly as us and in a one-off game we can defeat anyone."
Highlights: Wales Women 16-15 England Women
Evans played a key role in Wales' first-ever win over England, kicking the decisive last-minute penalty in February's 16-15 Six Nations clash.
She knows her team will be facing an England XV thirsting for revenge when the two sides meet in this season's Women's Six Nations opener in February, and in two summer World Cup warm-up games.
"We've never beaten England away, that would be huge for us," said Evans.
"We want a really good Six Nations to build for the Cup, hopefully we'll have some key players back from injury to help."
