The SubAir surface aeration and vacuum-powered drainage system, or simply the SubAir system, refers to a technology that helps prevent water logging as it is capable of draining water 36 times faster than normal conditions.
The system functions by sucking the water out via the super absorption pipes at the rate of over 10,000 litres a minute from the time it begins to rain at the ground. The technology works via activated signals from the remote sensors installed in the field.
The state-of-the-art facility was installed at Chinaaswamy Stadium in Bengaluru to eliminate the need of match cancellations or delays due to wet outfield conditions.
The aeration function of the SubAir system offers an optimal growing environment for the root zone, thereby minimising turf diseases, algae, excessive thatch and black layer.
The Karnataka Cricket Association (KCA) had installed the SubAir system at a cost of INR 4.25 crore. The maintenance cost of the state-of-the-art technology is around INR 7 lakh annually.
