EXPLAINED: Sub Air system that could have helped start Nagpur T20I race on time even after rain | Cricket News

As the rain continues to affect the 2nd T20I between India and Australia, fans are angry that the Vidarbha Cricket Association Stadium does not have the sub-air system to dry the water features and restore the right conditions for a cricket match. After it rained all day in Nagpur and other regions of Maharashtra, some areas in the ground were wet even after the rain stopped. And because there was sunshine to dry it out, the officials could only wait for the outfield to be playable again. If there had been a subair system, the match could have started sooner rather than later.

What is the sub-air system?

The sub-air system is a technology invented by the US-based company SubAir Systems. It is a surface aeration and vacuum operated drainage system. This technology has the capacity to remove water from the ground 36 times faster than under normal conditions. In India, only M. Chinnaswamy Stadium in Bengaluru has installed this system and the Karanataka State Association had to pay Rs 4.25 crore to make it happen. It has helped delay cricket matches due to the wet conditions on the ground.

How does the sub-air system work?

What this system does is suck the water out through a super absorption pipe. From the moment it starts to rain, it can suck more than 10,000 liters per minute from the ground. Remote sensors are installed in the field that help the technology work through activated signals.
