The linings of both Tettenhall Pool and East Park Pool have been cleaned with the pumping mechanisms tested and any cracks which may have formed over the winter months sealed.
Severn Trent Water carries out the time consuming task of filling each pool - Tettenhall Pool holds 153,978 gallons of water, or 1,231,842 pints and because of its size will take nearly 4 days to fill, while East Park Pool holds 32,995 gallons, or 263,960 pints.
Finally, the purity of the water will be tested before the pools are officially opened to the public.
Councillor Steve Evans, the City of Wolverhampton Council's Cabinet Member for City Environment, said: "The paddling pools at Tettenhall and East Park are always incredibly well used, and with some forecasters suggesting 2016 could be the hottest summer for 40 years, we're expecting them to be even more popular this year."
The pools are expected to open in time for the Bank Holiday Weekend, 28 to 30 May, and will remain open throughout the summer.
