Ranchi, March 26: Worried about the chlorine content in swimming pools? An alternative is here and Sapphire International School would be one of the firsts to implement it.

Two indoor solar-heated swimming pools boasting an ozone-based filtration plant are under construction. The solar heating technology is estimated to cost the school anything between Rs 35 and Rs 75 lakh, while the whole project is estimated at over Rs 1 crore.

The ozone-based technology has been imported from Australia and the construction of the two pools is expected to be complete by April-end.

“At present most filtration plants use chlorine. But for the first time we would use an ozone-based filtration system,” said Rohit Sahu, the chairman of Sapphire International School.

Ozone is considered to be an effective alternative to chlorine. Though installation of the ozone system is relatively higher, it would result in a much cleaner pool. This means that dirt, grease, organics and other materials will be filtered out much faster than the chlorine system. Ozone would also help kill bacteria and other infectants.

In fact, S.S. Choudhury, a dermatologist at the Rajendra Institute of Medical Sciences (RIMS), said ozone is a smart alternative.

“Ozone gets mixed with water and is a great disinfectant. It not only improves water quality but also leaves no chemical residue, unlike chlorine. It is a natural by-product and increases the amount of oxygen in the water. Moreover, it is good for the skin.”

The ozone technology would also help reduce operating and maintenance cost. Chlorine is known for destroying pool infrastructure and rusting out ventilation systems. With ozone, one would not face any such problems.

The two pools would measure 25m X 12m and 4m X 12m, respectively. The pools would be covered with bright magnesium sheets to avoid rust. A first-aid room would also be built close at hand.

The pool will work on a solar heating panel. Water would be transferred into the pool through tubes that also absorb solar heat. The system could be electronically monitored and the temperature could also be regulated.

To facilitate a complete workout for students, a multi-gym would also be built on the premises of the larger pool. Here, students could avail of ab-crunchers, rowing machines and treadmills, besides other equipment. Aerobic classes would also be held here.

Sahu said two coaches would be hired to train the boys and girls.

The chairman added that no separate fee would be charged from the students. “This facility comes under the sports fee,” he said. However, the students would have to buy their own swimming costumes.
