With the addition of the wave pool and other aspects of the $5.7 million expansion now underway at Splash in the Boro water park, Statesboro's largest generator of part-time summer jobs for teenagers will hire even more young people. In recent years, Splash alone has employed more than 200 summer workers in the range from 16 years old through college-age and older, and the expansion is boosting that number to nearly 300. Overall, Statesboro-Bulloch County Parks & Recreation will have somewhere around 450 summer employees, also including those hired for its sports and after-school programs and the maintenance of other parks, said Mike Rollins, the department's director.
