Big Kahuna's Water & Adventure Park — Humunga Lazy River - commercial aquatic construction by Torwyn Solutions

Big Kahuna's Water & Adventure Park — Humunga Lazy River

Destin, FL
March 2023

Project Summary

Mid-December 2022 to mid-March 2023 - the river that started it all in the big leagues. Like other Big K attractions, covered in layers of paint and leaked water so badly couldn't maintain correct height even with two wells. Took long time to fill because water had to soak ground around it first. Approximately 6-7 staircases all around, handicap lift room, wave generator interior lined, small splash pad for slide, coping all the way around, 2 LARGE surge tanks, several still-big surge tanks (could comfortably fit 3 people standing), and bunch of rectangular concrete skimmer boxes with pipe in bottom. Trained on this project, managed it, put in countless hours figuring out and designing solutions. Result: watertight, beautiful, long life ahead without annual repainting and crack refilling.
