00:00water is safe water, we need to be careful about that.
00:05We need to think about how clean the water that falls on the roof of the house will be.
00:11Even there, when we have the opportunity to collect bird litter, it is in a low quantity.
00:20So, in order to recharge the groundwater,
00:25we need to clean the water that falls on the roof of the house with a sand filter.
00:32By doing this, we can recharge at least 30-40% of the water that falls on the roof of the house.
00:42It is difficult to recharge 100% of the water in any situation.
00:46Mr. Karunakareddy, how much of the groundwater in a region can be used?
00:51How much do you use? How much do you recharge?
00:54We need to do mapping with GIS technology.
00:58We need to do geo-fencing in every area.
01:01How many people live in this particular area?
01:05Even if there is no exact figure, we can get a figure of 60-70%.
01:10Based on the number of houses and apartments, we need to do GIS mapping.
01:16In this particular area, we need to do hydro-geology mapping.
01:21There are opportunities for us to recharge water through technology.
01:26We all know that Hyderabad is a tropical area.
01:31It is difficult for us to send all the water that comes to Hyderabad to Hyderabad.
01:36But, by mapping this properly and decentralizing it,
01:42we can do this kind of management.
01:47Secondly, we need to do winnowing.
01:50For example, like Mr. Ramachandran,
01:53let us take the LB Nagar area.
01:56In the LB Nagar area, what is the population density per square kilometer?
02:01In Madhapur, Kokadpet, Gachibowli areas,
02:07what is the population density per square kilometer?
02:11For example, the rainfall in this area is 750 mm per year.
02:19Here, we get 750 liters per square meter.
02:25By converting this per square meter into per square kilometer,
02:29we need to use only 60-70% of the population.
02:35We need at least 30-40% buffer.
02:40So, that is very important.
02:42Secondly, recharging.
02:45How do we recharge?
02:47We need to map the aquifers in this particular area.
02:51How much soil can be sent?
02:53If there are public parks on the land,
02:57or if there are public utilities,
02:59or if there is an underground sump,
03:02where can the underground sump be sent to the public?
03:06Thirdly, individuality.
03:08Whether it is an apartment or an individual house.
03:10In Jubilee Hills, Banjara Hills, or Madhapur,
03:14there is no question of an independent house.
03:16Because there is a Gwajam,
03:18which is more than 2-3 lakh rupees,
03:20all the apartments there are vertical.
03:22So, for recharging,
03:25how much water is needed per capita?
03:27According to urban planning,
03:29per person needs up to 150 liters of water.
03:33Out of these 150 liters,
03:35how much water is needed for what?
03:37When we flush the toilet,
03:39according to the current technology,
03:42we need to have a dual pumping system.
03:44If there is dual pumping for flushing,
03:46the flush water needs to be less.
03:48Then what happens is,
03:50for horticulture,
03:52for washing cars,
03:54many people in Hyderabad don't know,
03:56from 180 to 200 kilometers,
03:58water is pumped.
04:0040% non-return revenue.
04:03If we pump 100 liters,
04:05we will only have 60 liters of water.
04:0740% of the water will be wasted.
04:14Along with this,
04:16if we can do the pricing properly,
04:18then what we can do is,
04:20management,
04:22which is important for many people,
04:24how important is management?
04:26We need to improve the groundwater.
04:28We need to reduce the utilization of groundwater.
04:31What we are doing is,
04:33we are mining water as much as possible.
04:36In Hyderabad,
04:38in some places it is 300 feet,
04:40in some places it is not even 1500 feet.
04:42The reason is,
04:44we have already used up all the water.
04:46We are not recharging it.
04:48What happens because of that is,
04:50water crisis, water deficiency.
04:52There is a big difference in recharging
04:54for re-use and re-use.
04:56Even when it rains,
04:58we do not have water.
