Case Study from HydroFLOW Canada

Indoor pool chlorine reduction at Lyle Hallman pool

Indoor pool chlorine reduction was the aim at Lyle Hallman pool, a 25-metre indoor pool owned and operated by the City of Kitchener in Ontario, Canada. With around 300 to 500 swimmers a day, keeping the water right took a lot of chlorine, shock treatments added to it, and staff noticed a strong chlorine smell. One HydroFLOW® P160 was installed on the pool circulation system, and chlorine use and water quality were monitored. Daily chlorine use fell by 51%, no shock treatment was needed while chloramines stayed low, and staff reported clearer water and less odour.

The Challenges

  • Indoor pool chlorine reduction was needed at a busy public pool
  • Around 300 to 500 swimmers a day increased chemical demand
  • Chlorine shock treatments added to chemical use
  • Staff reported a noticeable chlorine smell

The Solution

  • Unit installed: one HydroFLOW® P160
  • Installation point: pool circulation system
  • Pool: 25-metre indoor pool
  • Swimmers: approximately 300 to 500 a day
  • Monitoring: daily chlorine readings and chloramine levels

For indoor pool chlorine reduction without changing how the pool was run, the P160 was fitted to the circulation pipework. Daily chlorine readings and chloramine levels were then followed, so that any cut in dosing could be checked against water quality, and the need for shock treatment was tracked alongside them.

Independent Verification

All results in this study were measured and verified by third-party facilities managers and technical staff.

Summary

At Lyle Hallman pool, HydroFLOW® cut daily chlorine use by 51%, and no shock treatment was needed while chloramines stayed low. Staff noticed clearer water and less chlorine smell, and the calculated saving was $8,300 a year, with payback just over 20 months. In a busy indoor pool, the smell people notice comes from chloramines, so less chlorine with chloramines kept low is the result that swimmers and staff can feel.
