National Disaster Response Force (NDRF) and teams began relief works in rain affected parts of Hyderabad on Saturday.
Some residential areas remaind under water for the fourth successive day.
Personnel from the Army and the NDRF swung into action to relief works in Alwal, one of the worst hit suburbs in Hyderabad.
There was no respite for flooded residential colonies in Alwal, Kukatpally, Miyapur, Nizampet and Begumpet as more rains lashed the city since Friday night.
The locals saved 40 children when a school bus was stuck in flood water in Dharaninagar in Kukatpally on Saturday morning.
According to eye witnesses, the driver ignored the warning and tried to pass through flood water. The children belonged to a private school, which was open despite the government declaring two-day holiday for all educational institutions in the city.
Telangana Deputy Chief Minister Kadiam Srihari said action would be taken against the schools which were open despite the government orders.
In the meantime, people in flooded areas were facing shortage of drinking water, food and other essential items. Some non-governmental organisations were distributing food, milk and water packets.
