DAY 14

On the 21st, we started an hour earlier than usual, because we had a guest, Mr. Gautham Reddy, the head of RAMKY Industries, who came to address us. He shared with us a lot of valuable information about waste management and waste recycling.  He informed us about how our city alone produces about 4000 tons of waste EVERYDAY.

His speech was very informative, and  through it, he informed us about the importance of segregation of waste. Through his speech he made it possible for us to think on a broader spectrum about how if we produce more waste and do not segregate it, we would have to face the consequences.  He had to leave early for Delhi, so his speech was short and to the point.  We wished it was longer as we wanted to talk in more detail about the problems being faced by the people due to production of so much waste.

After his speech, we got some time to work on our projects after which we were off to the Sewage plant in Necklace Road . This sewage plant did smell terrible, but it was interesting to find out how the dirty water is treated to make pure water that is sent to the Hussain Sagar Lake. This water contributes greatly as it helps purify the lake bit by bit.

We had an amazing guide who explained to us the three different steps of clearing the water and also explained to us the Sewage Plant's objective  to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Using advanced technology, it is now possible to re-use sewage effluent for drinking water. 

After we returned to school, all of us decided that it was time we got serious and started doing our project work, so after that we worked on them until 3 o' clock, after which we left for home.
