Case Study
Wankhede Stadium Turf Revitalization
Optimizing water quality for superior turf health
Summary
Wankhede Stadium, an iconic cricket venue in Mumbai, required high-quality water for
stadium turf maintenance. was facing a recurring issue of grass degradation,
uneven dew retention, and pitch dryness, especially during peak usage in the summer IPL
season. Despite standard maintenance practices, the ground conditions were inconsistent
and required high water input with suboptimal results. Avior Aqua deployed its Nanobubble
Technology to purify and stabilize water quality without the use of chemicals or conventional
RO systems, aiming for enhanced potability and ecological safety.
Location
Wankhede Stadium, Churchgate, Mumbai.
Client
Cricket Association of Mumbai.
Type of Case Study
Potable Water Quality Enhancement.
Start Date
08th May
2025
End Date
10th June
2025
Objective
To evaluate the effectiveness of nanobubble
technology in:
→ Improving grass health and color consistency.
→ Reducing water consumption.
→ Reducing water consumption.
→ Enhancing pitch moisture retention.
→ Ensuring dew control for late evening matches.
→ Ensuring dew control for late evening matches.
Problem
Water samples collected on 05/05/2025
revealed:
High Total Dissolved Solids (TDS) : 750 mg/L.
Low pH : 6.09, acidic in nature.
High Electrical Conductivity : 1153.8 μmhos/cm.
Turbidity: 5 NTU.
Alkalinity imbalance and elevated hardness
(CaCO₃ – 150 mg/L).
Presence of ammonia and magnesium beyond
desirable limits.
Solution Implemented
Avior Aqua deployed its Nanoxy Nanobubble Generator at Wankhede Stadium for a 30-day pilot program. The system infused ultra-fine oxygen nanobubbles (<100 nm) into irrigation water to improve oxygen delivery at the root level, stimulate microbial soil activity, and enhance water penetration.
Results
Visual Improvement:
• Significant visual contrast between pre and post treatment turf quality.
• Patchy and dull zones revived into lush green, visibly healthier areas (See attached before-after photos).
• Patchy and dull zones revived into lush green, visibly healthier areas (See attached before-after photos).
Pitch Performance:
• Moisture retention increased, reducing over-drying of the central pitch zone.
• Dew impact during night matches minimized, improving match playability.
• Reduced patch recovery time.
• Dew impact during night matches minimized, improving match playability.
• Reduced patch recovery time.

Conclusion
In just 30 days, Avior Aqua’s nanobubble technology delivered a holistic transformation of Wankhede Stadium’s turf and pitch conditions. The visibly greener and denser grass,
enhanced root zone health, and uniform color restoration significantly improved the overall
aesthetics and playability of the ground. Dew reduction and superior moisture retention
created optimal match conditions even during peak evening hours. Additionally, the system
turned poor-quality tanker water into a clean, odorless, and pH-balanced resource—
sustaining the turf without any chemical inputs or RO filtration. The pilot sets a new
benchmark for sustainable, non-invasive turf management and water optimization for
stadiums and large urban landscapes.
