The World Rugby Sevens Series is due to resume in Canada later this month at Vancouver on September 18 and 19 followed by an event in Edmonton on September 25 and 26.
The events in Canada will form the 2021 Series with the title awarded in Edmonton as World Rugby look to minimise travel amid the ongoing Covid-19 pandemic.
The events at Vancouver and Edmonton are also due to feature world-class women’s fast four competitions.
World Rugby has already confirmed there will be no relegation from the 2021 Series and the results will not contribute towards seedings for any other future events.
Treharne and Williams will be part of a men’s GB squad for the competition which will see 12 teams divided into three pools of four using the same format as the Olympics.
GB Sevens have been drawn in Pool B with Ireland, Hong Kong and Jamaica.
Tom Bowen, Alex Davis, Robbie Fergusson, Ross McCann and Max McFarland, who all featured for Team GB as they finished fourth at the Tokyo Olympics, are in the squad with Treharne and Williams.
Men’s head coach Tony Roques said: “It’s a real mixed squad. We’ve got guys who didn’t go to the Olympics but were part of the training squad and it will be great to see them get the opportunity to play.
“We’ve also got players who have come back from the Olympics and can’t wait to pull on the GB Sevens shirt again.
“It’s also the first time GB Sevens have competed on the World Series which means a lot to staff and players.
“This is a nice opportunity to continue what was started by the lads who went on the Olympic journey and ensure sevens stays visible. Thank you to the National Lottery for their continued support of our journey.”

Joyce lit up the women’s rugby sevens in Tokyo with her stunning speed and eye for the try-line as Team GB finished fourth.
Women’s head coach Scott Forrest has named a 13-player squad with GB set to take on hosts Canada, USA and Mexico in Canada.
Mexico men’s and women’s teams were added to the event following the late withdrawal of France’s teams due to Covid-19-related international travel logistics issues.
The women’s fast four competition format, which was previously employed at the men’s Series event in Hamilton in 2019, will see all teams play each other before the top two play for gold and the other two teams compete for third place.
Forrest said: “We’ve got a core group of players who were involved and played in Tokyo which is excellent. It gives the programme and the team some consistency which I think is really important. This is the next step on our journey.
“One of the messages we always spoke about was that this journey was bigger than a medal. I would hope the way the team performed in Tokyo would have had an impact back home in terms of the exposure of sevens and also inspired more girls to start playing the game.

“The next few months for us are the next chapter in our journey and the next opportunity to go and play sevens. Having the core group of players is great but if you look at the rest of the squad, there is a really nice mix.
“Finally, I’d like to thank the National Lottery for their continued support and opportunity for the GB7s programme during this period”
