Secondary Air System in Cricket Stadium: Despite the innovative drainage facility, the chances of a 5th T20I resumption between IND vs SA look bleak.

In the fifth T20I of the ongoing South African tour of India at the M. Chinnaswamy Stadium in Bangalore, the rain gods made an appearance again after just 3.3 overs in the match.

It should be mentioned that the start of the game had already been delayed by 20 minutes due to a brief but intense downpour just before the first delivery, which caused the decisive game of the series to be reduced to 19 Overs-a-side. . each.

The bad news for fans is that the current rain at the venue does not look like a passing downpour as the downpour is quite intense, which has started to pierce the spirits and excitement of onlookers.

The aforementioned development meant that the match loses an Over for every four minutes lost, which ultimately means that for it to be a 5 Overs contest, play will need to resume at 10:12 p.m. IST, which is approximately 25 minutes into the game. now (at time of writing).

A torrential downpour seen in the stadium meant that despite the SubAir system, the drying process will take some time, if the rain gods show some mercy.

The SubAir Surface Aeration and Vacuum Drainage System, or simply the SubAir System, is the first cricket infrastructure innovation in the country, which was installed at Mr. Chinnaswamy Stadium in 2017.

The technology helps prevent water from accumulating on the stadium grounds for a long time, as it is said to be able to drain water 36 times faster than under normal circumstances (source of information: Cricbuzz).

The system works by drawing water through the super absorption pipes at over 10,000 liters per minute from the moment it starts raining on the ground. The technology works via signals activated by remote sensors installed in the field.

The aforementioned technology resulted in an investment cost of INR 4.25 crore, borne by the Karnataka State Association Stadium (KSCA). Moreover, the maintenance of this vacuum powered drainage system will force the KSCA to reduce its maintenance cost by INR 7 lakh per year.
