Bosses from the firm which runs Aqua Vale will be grilled by councillors later this month.
Everyone Active pays the district council £500,000 to manage the complex on its behalf.
On Tuesday, June 30 managers will face the finance and services scrutiny committee for its annual review of the contract.
Aqua Vale received 157 complaints last year, representing 0.024% of the 644,457 visits to the centre during 2014/15.
There were 368 accidents, an increase of 8.9%, including six which were serious enough to be reported to the Health and Safety Executive.
A report to councillors said many of the minor injuries were suffered by young children in the leisure waters.
Everyone Active’s objectives for 2015/16 include increasing visitor numbers, launching a new GP referral scheme to improve the health of inactive people, retaining and promoting more of its staff, developing user forums and building a client base for the new synthetic turf pitches in Vale Park.
