The budget for the new Allander Leisure Centre has been increased from £18 million to £25 million.
The council’s contribution has been more than doubled - from £8m to £19m.
The replacement project is scheduled to formally commence in early 2021 and the Champions Group has been re-established and met recently, with a second meeting scheduled for next month.
The Champions include East Dunbartonshire councillors, representatives from the main user groups and local community organisations, council officers and EDLC Trust staff.
Their job is to provide valuable input into the scope and future design of the new Allander Leisure Centre.
Councillor Rhondda Geekie, council leader, said: “I am delighted that the Allander Champions Group has been re-established and want to thank everyone who attended the recent meeting.
“It has been a complex process to finalise the planning and land transactions between the various parties, and I commend all involved for their patience - particularly local residents.
“The Champions’ enthusiasm to take forward the process of designing and developing the new Allander Centre is inspirational and I look forward to maintaining the momentum.
“I’m glad a second meeting has already been arranged for December, reviewing previous work on specifications for the new centre.”
Councillor Geekie added: “The council remains fully committed to the Allander Leisure Centre project - which is reflected in the additional £11m of investment within the capital programme.
“This is on top of Bearsden Community Hub, the future Milngavie Community Hub, new primary school and rejuvenation of Kilmardinny House.”
