Home 9 Case Studies and Results 9 Colmar Pool: 2,535m³ Water Saved, 0.7-Year ROI
Key results
2,535m³ annual water saving
15% chlorine reduction
0.7 year ROI

Case Study from HydroFLOW France

The Challenges

  • High backwash water consumption per wash
  • 78 filter washes per year
  • Heated chlorinated water wasted during washes
  • Rising operating costs from water and energy use

The Solution

One HydroFLOW® P160 unit was fitted upstream of the filtration system in October 2014. The signal supports better flocculation before filtration, reducing backwash demand and cutting losses of heated, chlorinated water across the indoor pool.

Key Outcomes

R

Annual backwash water cut by 2,535m³

R

Heat loss reduced by 41,275 kWh

R

Filter washing used 15% less chlorine

R

Return on investment in 0.7 years

Independent Verification

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