M Chinnaswamy Stadium: How Cutting-Edge Drainage System Ensures Cricket Continues After Rain Interruptions In Bengaluru

The ongoing ICC Cricket World Cup 2023 match between Pakistan and New Zealand at M Chinnaswamy Stadium in Bengaluru has been halted due to drizzle on Saturday (November 4). The fans and organisers are hoping for the match to be completed as it isn't just evenly poised but also critical from the tournament's point of view.

Both Pakistan and New Zealand's fate for qualification in the semi-finals hangs in balance on the result of this virtual quarter-final. A win will in Bengaluru will keep their hopes alive in the competition.

The iconic M Chinnaswamy Stadium in Bengaluru is one of those venues in India where rain plays spoilsport every now and then. The weather in Bengaluru is pretty unpredictable as rain plays hide and seek for the most part of the year, in return dampens the mood of the players and fans alike.

To counter the impact of rain interruptions and ensure matches reach a fruitful conclusion, the Karnataka State Cricket Association in 2016 set a groundbreaking precedent for cricket stadiums worldwide by implementing the state-of-the-art subsurface aeration and vacuum-powered drainage system from SubAir, USA.

Cost of SubAir Drainage System?

The imported SubAir system cost approximately Rs 4.25 crore to the KSCA but since its installation, this innovative technology revolutionized the way the ground is prepared for matches, ensuring minimal disruption due to rain.

Swift Drainage, Swift Resumption:

One of the primary advantages of the SubAir system is its ability to rapidly and automatically manage water accumulation on the outfield. As soon as rain begins, the system springs into action, preventing the build-up of water and swiftly evacuating any standing water.

In fact, it can remove water 36 times faster than traditional gravity-based drainage methods. This means that even if it rains in the early hours of the day, the system responds without manual intervention, activating suction through embedded remote sensors. Water is efficiently drained at a rate of over 10,000 liters per minute, making the outfield ready for play within minutes of the rain subsiding.

A Game Changer for Cricket:

The implementation of the SubAir system not only enhances the fan experience but also addresses a significant financial risk associated with matches getting washed out. With losses that could amount to Rs 80-100 crore (US$12-15 million), including losses to spectators, TV broadcasters, advertisers, and in-stadium advertisers, there's a lot at stake. The SubAir System greatly mitigates this risk, ensuring that more games can be saved in the future.

Benefits Beyond Drainage:

The SubAir Sport System not only expedites drainage but also promotes healthier, stronger, and safer turf. Its aeration function operates continuously, creating an optimal environment for the root zone, which minimizes turf diseases, algae, excessive thatch, and black layers. Additionally, the aeration function reduces the surface temperature on the turf, enhancing player comfort.

Meticulous Ground Preparation:

To complement the SubAir system, the renovation of the M. Chinnaswamy Stadium's outfield adhered to USGA standards. This extensive project involved excavating over 1,000 truckloads of soil, grading, compaction, laying geotextile, trenching, and installing perforated pipes ranging from 150mm to 800mm in diameter, totaling over 4.5 kilometers.

The groundwork also included a layer of finely graded sand mixed with organic manure and nutrients before the Bermuda grass was planted. The result is an outfield that possibly surpasses the best in the cricketing world.

Sustainability and Water Harvesting:

The integration of the SubAir system also optimizes water use for the turf and captures rainwater or excess irrigation, redirecting it for rainwater harvesting. This approach ensures efficient water management and contributes to the stadium's sustainability efforts.

The M Chinnaswamy Stadium's adoption of the SubAir system has not only set a precedent but has also drawn the attention of other cricket stadiums looking to modernize and ensure uninterrupted play. This technology, which has been successfully used in various sports worldwide, has now become an essential component for cricket stadiums worldwide.

SubAir System - A Win-Win Deal For All Stakeholders

The M. Chinnaswamy Stadium's investment in the SubAir system has not only transformed the way cricket grounds respond to rain but also minimised the financial risks associated with match cancellations.

By enhancing drainage efficiency and promoting healthier turf, the stadium ensures that cricket fans enjoy uninterrupted matches, and millions of dollars are safeguarded. This forward-thinking approach represents a significant step in the evolution of cricket stadium technology and sets a new standard for the industry.
