Waterman showed superb finishing skills for her two tries
England Women booked a World Cup semi-final against Australia with a six-try, 37-10 win over the United States.
Full-back Danielle Waterman grabbed the first of her two tries and Katy McLean landed a penalty before the US hit back with a Natalie Machino try.
But Kat Merchant collected McLean's neat chip and Waterman sliced through again to help England into a 20-5 lead.
Emily Scarratt grabbed the fourth on the resumption before further scores from Amber Penrith and Maggie Alphonsi.
England head coach Gary Street said: "I'm pleased with that performance, we certainly would have taken that before the match started.
"The girls really showed their determination and physicality tonight. The forwards were tremendous and set the platform, and the backs capitalised. This was a good day in the office.
"The Americans really hit the breakdowns hard and they put in some hard tackling. I think we just kept our resolve, and in the second half especially we played in the right areas and took our chances when they came."
The hosts now advance to a last-four meeting with Australia, who secured the best runner-up spot, at the Twickenham Stoop on Wednesday (2015 BST K0).
"That is going to be an exciting one," Street added. "We have never played them before so there is a sense of the unknown here.
"They won the Rugby World Cup Sevens last year so we know they are used to the big stage, and I think it is going to make for a really thrilling semi-final."
Australia needed to beat South Africa by 56 points in their final pool match and achieved the feat with a 62-0 victory.
That denied Ireland, who beat Kazakhstan 37-3 on Saturday, a semi-final place. The Irish, like Australia, finished on 10 points but lost out on points difference.
They will instead battle it out with Canada, USA and Scotland for the fifth to eighth places.
South Africa, Wales, Sweden and Kazakhstan will play-off for the ninth to 12th places.
Wednesday's first semi-final will feature defending champions and favourites New Zealand, who beat Wales 41-8 on Saturday, against France, who overcame Canada 23-8 in their pool decider.
That game, also at The Stoop, kicks off at 1800, with the same venue hosting next Sunday's final.
