Worcester Warriors' Sixway stadium is in the Wychavon district, between Droitwich and Pershore. The team secured their promotion to the Aviva Premiership in a thrilling two-leg clash with Cornish Pirates in May.
Speaking at the council meeting, Wychavon Chairman Councillor Tony Miller said: "Worcester Warriors - how proud are we to have them in Wychavon? Very proud!
"They moved to Sixways in 1975 and that was welcomed by everyone. The way it has grown and inspired the area is tremendous.
"Your promotion is a marvellous achievement. I would really like to say thank you for the hard work and dedication of the team, the managers, the players and the coaches - and for everything you have doen to really put Wychavon on the map."
Wychavon Leader Cllr Paul Middlebrough said: "I would like to stress the importance of the relationship between the club and the council. You bring thousands of people into our area, into Droitwich and Pershore - and they spend money in those towns.
"The economic activity you you bring to Wychavon is fantastic. We thank you for that and I think all the traders and businesses in the area want to thank you.
"I would like to wish you every success now that you're back in the Aviva Premiership."
Richard Hill, Warriors Head Coach, told councillors: "I would like to thank Wychavon District Council for all their support. I hope you stay with us again next year in the Premiereship."
Charlie Little, of Worcester Warriors, said: "We all appreciate the suport you give us and we genuinely appreciate our location in Wychavon."
He also mentioned that, in addition to the established conference centre at Sixways, the club hoped to shortly confirm plans to bring a hotel and leisure centre to the site.
