More than 3,000 people a week are now using the Trinity Swimming Pool since Bedford College took over the former Bedford High School.
The award-winning college pledged to make facilities at the prestigious Bromham Road site available to the community.
The 25 metre pool is now UV cleansed making it more environmentally-friendly and more welcoming for those who have allergies and other health conditions.
It is used by clubs and groups seven days a week.
Meanwhile other facilities such as the sports hall and gym are increasingly booked up.
Deputy general manager of BCS Ltd, which runs Trinity Arts and Leisure, Amanda Riches, said: “We are finding more people turning to our community facility for their fitness and well-being.”
The Trinity Theatre is also now open to groups and clubs.
The Bedford Film Society, Marianettes and Bedford Dramatic Club stage their events there regularly and the venue is also open for community, corporate and family activities.
Amanda added: “We are proud to have made such a success of the services here to the community in such a short time and look forward to more joining us in the year ahead.
