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.
