Fire Station -MAKE A RUN FOR IT!

Fire Station - Make a run for it!

The fire station at Rajajinagar Bangalore can teach you what a rescue operation entails. It can also impart valuable lessons in water conservation

Firemen primarily tackle fire accidents, right? They also help during natural calamities, evacuating people to safety. Their main job remains fire-fighting, for which water is their primary raw material. Water, in any fire station, is stored in a large underground sump. Every fire station has a dedicated, express water line provided by the Bangalore Water Supply and Sewerage Board. The service is unmetered.

 However, for months on end, a fire station may not receive a distress call. The equipment, which lies unused, may not work when required. So, mock drills are conducted every week. But mock drills consume a lot of water. 
The Karnataka State Council for Science & Technology decided to take up rainwater harvesting at the 2-acre Rajajinagar fire station as part of its work in public spaces. As fire stations do not need potable quality water, Karnataka State Council for Science and Technology suggested that the fire station harvest its roof-top rainwater.
Water collected from the roof (area 300 sq. m.) is filtered and stored in an underground sump. An additional sump with a capacity of 60,000 liter is built. This sump can fill 10 fire trucks. It also nurtures a lovely garden.
