SubAir Drainage System: Revolutionizing water management at Chinnaswamy Stadium

The SubAir drainage system, implemented at Bengaluru’s M Chinnaswamy Stadium, has revolutionized how rainwater is managed on cricket grounds, enabling quick resumption of play after downpours. This state-of-the-art system, widely used in football grounds, golf courses, and rugby stadiums globally, is designed to clear standing water from the outfield in record time, minimizing weather-related disruptions.

The system operates through a network of perforated tubes, drains, and pipes installed beneath the outfield surface. These pipes are arranged in a closed-loop structure connected to the SubAir system. When rain hits the field, the water is quickly sucked up and transferred to a nearby tank or drainage system. Brijesh Patel, former secretary of the Karnataka State Cricket Association, highlighted that the system removes water at "36 times the speed of gravity," ensuring rapid drainage of the outfield, as reported by First Post. 

In addition to drainage, the SubAir system supports turf health by monitoring moisture levels, salinity, and grassroots temperature using embedded wireless sensors. It can pump in cool air or water as required, while also aerating the roots to keep the grass healthy.

Installed with a built-in sprinkler system, the SubAir technology allows groundskeepers to maintain the field efficiently, ensuring that play can resume promptly after rain stops, helping minimize delays and enhancing game readiness.
