Repairs costing £40,000 are needed to the pool at Stocksbridge Leisure Centre – meaning it will not be able to reopen in the ‘short term’.
Campaign group 4SLC, which has reached an agreement with Sheffield Council to reopen the centre – closed due to council budget cuts, said the news was a ‘major blow’.
Surveyors have said there is a serious problem with the concrete structure supporting the pool at the Moorland Road centre.
But 4SLC said the news will not derail their plans to reopen the centre.
Faye Howard, one of the organisers at the campaign group, said: “We are not giving up. There’s massive will in Stocksbridge for this to happen. We have come too far.”
The group said it was disappointed with the news, but that the likely cost of repairs was money that could be found.
The group, which is working with Stocksbridge Town Council, has commissioned a detailed quote for the repair work and fundraising events are planned to bring in the necessary cash.
The next fundraising event organised by the group will be a raft race at the Peak Pursuits Underbank Activity Centre on Sunday, July 21.
Stocksbridge Leisure Centre closed in May, but last month agreement was reached between 4SLC and Sheffield Council to reopen the building.
The council agreed to contribute £179,000 – less than half the previous annual £400,000 subsidy.
Stocksbridge Town Council and 4SLC are to find the extra cash to cover running costs.
A petition against the closure had earlier attracted about 1,500 signatures and 4SLC was taking Sheffield Council to a judicial review over the closure plans.
The group has not revealed when it is likely to reopen the centre to the public.
In the long-term, the building – which has a swimming pool and teaching pool, and sports hall – requires modernisation, including full disabled access.
Sheffield Council has pledged that if the centre does not reopen, the land will not be built on.
Long-term proposals for a new swimming pool are also being discussed as part of the new £40 million retail scheme on old steelworks off Manchester Road.
