Crowds are expected to gather at Tettenhall Pool in Upper Green, Wolverhampton, on Saturday.
But council bosses have warned the water quality must meet the appropriate standard before it can reopen – and families are urged to avoid it for the time being.
Councillor Steve Evans, cabinet member for city environment and climate change, said: "The pool has been filled and treated, and tests to ensure the water quality meets the required standards for bathing have been sent to a lab to be checked. During this time people are asked not to use the pool and signs advising this are located around the site.
"As long as the water quality meets the appropriate standards, the pool is expected to open from May 28.”
And people have been reminded to be respectful of people living in the village – and ensure they pick up any litter and keep noise low – should the pool reopen on Saturday.
Councillor Sohail Khan, who represents Tettenhall Regis, said: “The weather is getting nicer now and people flock there from all around – families love it.
“It’s been a difficult period for everyone due to Covid and it’ll be good for people to go when it opens, but I would urge people to be a bit responsible.
“Be respectful if you use the pool itself, and if you use the green for a picnic be mindful about the litter. Of course we welcome it opening, it’s one of the great things we have in the city and lots of people come down to see it.
“But please be mindful of residents who live close by and be respectful of people.” One person said on social media: “Cannot wait to visit the kids have missed this” whilst another added: “Great as long as everyone respects the area and disposes of their litter properly.”
Testing is currently taking place ahead of the reopening – checking it is safe to do so – and people have been urged not to use the pool whilst the checks are taking place.
The popular pool reopened last year, after two years away due to Covid-19. It was permanently closed during that period due to fears over Covid-19 cases and people gathering.
MPs and councillors said the move was necessary due to fears people could flout lockdown rules and lead to a spike in cases at a time when the NHS was under considerable pressure.
Frustration was sparked due to the pool being closed for the majority of 2019, throughout the summer months, due to necessary repair work after a consultation was held on whether it should become an outdoor gym instead.
More than 95 per cent of the 3,796 responses to the public consultation rejected plans for the gym and decided to save Tettenhall Pool – which reopened on August 1 in 2019, before closing in March 2020 due to lockdown.
