Nanobubble water quality enhancement at Wankhede Stadium
A 30-day pilot treating turf irrigation water with a NanOxy, with before-and-after water tests and the limits of the data.
Summary
Wankhede Stadium needed better water for turf maintenance. From 8 May to 10 June 2025 a NanOxy treated the irrigation water supplied to the ground.
TDS fell from 750 to 550 mg/L, pH moved from 6.09 to 7.50, turbidity fell from 5 to 3 NTU, hardness from 150 to 130 mg/L and ammonia from 1.5 to below 0.5 mg/L.
The water was for turf irrigation, not drinking.

What the ground team reported
The grounds team reported greener turf in patchy zones, better moisture retention on the central pitch, less dew during evening matches and quicker patch recovery. These are their observations, not measurements. No turf, soil or irrigation-volume data was recorded.
What this data does not show
- One stadium, one 30-day window, no control plot.
- Irrigation volume was not measured, so there is no water-saving figure.
- Turf observations are qualitative and come from the ground team.
