Chennai: Monsoon is here.
The rain has caused flooding but Tamil Nadu almost always lacks water.
More because of the absence of groundwater policy.
The wings of groundwater and surface resources from the Department of Public Works, in a study conducted last year, orders passed last week, found too much floating ground water (with more than 100% extraction) in 435 firkkas income (sub-divisions in it on it) in the state.
At least 26 firkkas in Chennai regency is too much exploited, including everything in Egmore-Nungambakkam, Fort-Tondiarpet, Mambalam-Guindy, Mylapore-Triplicane, Purasawalkam-Payprud, Bachelor, Maduravoyal and Tiruvottitiur.
Only Alandur, Sholinganallur, and Palikarani are safe.
Thanjavur, Delta Inti area, and Salem Top District-district that are too exploited.
The only consolation is that the number of fires exploited and critical respectively reduced from 462 and 79 each in 2017.
This study showed 99 Firkes had increased since the latest assessment.
Sustainable efforts such as strengthening the Bund and Refill Wells, Water Body Restoration and Dam Check by Government Institutions in recent years may have helped, but the condition of the country is precarious.
Water experts said TN was the third worst condition in terms of groundwater exploitation after Punjab and Haryana.
“First the country must harvest rainwater and use it wisely.
Most of our ‘closed’ basins, the meaning of demand cannot be fulfilled anymore.
Demand continues to grow with increasing population and urbanization, while the amount of rainfall remains the same.
Climate change has caused rainfall Intense in a shorter period, “said BV Mudgal, Anna’s water resource center, called for steps to store as much rainwater as possible.
In terms of ground water tables, tirupur, namakkal, district of Tuticorin and Dharmapuri have recorded a sharp decline.
Because of the availability of poor groundwater, providing household tap water connections in rural areas is piping.
City Administration and Minister of Water Supply Nehru and Rural Development Minister K R Perakaruppan Meets Union Jal Shakti Minister Gajendra Singh Shekhawat recently, seek funds for drinking water projects.
Urbanization that has quickly taken victims in the state, which is very dependent on its neighboring countries to meet the needs of irrigation and drinking water.
“People want to waste runoff as soon as possible.
The government has tried to overcome this by encouraging roof rainwater harvesting.
But we have to surpass it and see a sustainable urban drainage system (sud).
Suds has a focused approach to intercept rainfall and runoff at Various levels.
This provides sufficient opportunities and time for the possibility of infiltration and refills.
“Charging the shaft embedded in the storm waterways is the idea of welcome in the newly arranged integrated storm water channel in Chennai.
However, the scale of suds adaptation in storm waterways must start from the planning stage to increase the ground water level, quality and to reduce flooding.
Building regulations must be enforced to ensure that there are undeveloped areas in each project to facilitate water infiltration to the ground, “Balaji Narasimhan Professor in IIT Madras Engineering Environmental and Water Resources.
Narasimhan was associated with the development of a water resource information system at the Union Jal Shakti Minister.
At present, Chennai Metropolitan Air Ground (regulation) ACT regulates groundwater extraction in Chennai and 304 villages in Kancheepuram and Tiruvallur.
“The government is working on the draft groundwater bill, which will soon be introduced in the Assembly.
There is no mechanism for checking extraction for irrigation, which accounts for 70% of total extraction.
There are plans to put a hat on the power of the motor used for irrigation or limit the extraction hours, “said a senior government official.
The new law tends to form a water supervisory authority with legal force, led by the main secretary and consists of representatives from government institutions Like a twad board and metrowater.
This will force punishment for violations and dismiss the restrictions on the use of ground water.
Refill groundwater only ways to encourage thirst for TN
