Campaigners’ dream of building a new swimming pool in Swaffham could cost between £1.5 million and £6 million to fulfil.
The estimates were revealed during the annual general meeting of the town’s Swimming Pool Association (SPA) on Monday night.
And organisers of the latest campaign say the association has pledged to work with them in order to pursue the goal.
The ambition of a public pool in Swaffham was revived earlier this year when mothers Carolyn Watts and Helen Manson made their pitch for a heated outdoor pool to the town council.
Since then, the pair have been gathering costings for the project and surveying residents for their views on what they would like to see if such a facility is built.
The meeting was told that a six-lane, 25 metre outdoor pool, with changing facilities, would cost around £1.5 million to build.
However, an indoor pool of the same size would cost four times that much.
Ms Watts said they have already received around £4,000 worth of pledges towards the costs of the project, as well as offers of professional development help and volunteers to run the facility if it is built.
She said: “We are meeting with the SPA committee again in the imminent future as it was agreed to combine the forces of their long-standing reputation and our new approach.
“Our vision is to set up a charity run as a community interest organisation so our next steps are to move that forward so that we can begin sourcing funding in earnest.
Meanwhile, more than 400 people have also taken part in a survey, which Ms Watts said showed “a vast majority” in support of the outdoor pool proposal.
