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