Holistic Water Management System

Q. Why is this in News?

A. With the rapid growth of cities, water demand has exponentially increased. Even as aspirations cause people to migrate to urban areas, water depletion and scarcity remains a huge challenge staring at people’s faces in the near future.

Q. What is the Need for a Holistic Water Management System?

A. 

• Around 35 % of India’s population lived in urban areas as of 2020, it is expected to double by 2050.
• In urban areas, only 45 % of the demand is met using groundwater resources. Apart from this, climate change, pollution and contamination have also added to the burden on water resources.
• As water demand exceeds supply in most cities, water management needs to undergo a revolution to ensure most urban areas can be self-sufficient in the future.
• In India, there are different water management systems based on utilities like sanitation, urban water, stormwater and wastewater that deal with water-related issues in different localities. Since areas and localities define distribution and water allocation, it is often a challenge to find a unified solution.
• Thus, water management needs to undergo a revolution and Integrated Urban Water Management (IUWM) system for reliable supply is ensured in most urban areas for self-sufficiency in the future.

Q. What is an Integrated Urban Water Management System?

A. 

• About:
  • IUWM is a process, which ensures water supply, used water management, sanitation and stormwater management can be planned in line with economic development and land use.
  • This holistic process makes coordination among water departments easier at the local level.
  • It also helps cities adapt to climate changes and manage water supply more efficiently.
• Approaches:
  • Collaborative Action:
    • Clear coordination amongst all the stakeholders, it is easily defined and prioritizes accountability.
    • While effective legislation will help guide local authorities, engaging local communities will lead to faster solutions in water management.
  • Shift in Perception of Water:
    • It is essential to understand how water is inseparable in its connection to economic development, city infrastructure and land use.
  • Understanding Water as a Resource:
    • Water is a resource for various end goals thus it will be easier to treat different kinds of water based on agricultural, industrial and environmental purposes.
  • Customized Solutions for Different Cities:
    • IUWM focuses on specific contexts and local requirements and prioritizes a rights-based solution approach over a one-size-fits-all approach.

Q. What are the Challenges Regarding Water Management in India?

A. 

• Potential Rural-Urban Conflict:
  • Cities are rapidly expanding as a result of rapid urbanisation, and a large influx of migrants from rural areas has increased the per capita use of water in cities, which is causing water to be transferred from rural reservoirs to urban areas to meet the deficit.
• Ineffective Waste Water Management:
  • In a highly water-stressed environment, the inefficient use of wastewater is leaving India unable to make the most economical use of its resources. In cities, most of this water is in the form of greywater.
  • According to a recent report published by the Central Pollution Control Board (March 2021), India’s current water treatment capacity is 27.3% and the sewage treatment capacity is 18.6% (with another 5.2% capacity being added).
• Food Security Risk:
  • Crops and livestock need water to grow. Water is used extensively for irrigation in agriculture and serves as a major source of domestic consumption. Given the combination of rapidly declining groundwater levels and inefficient river water management, food insecurity is likely to follow.
  • The impacts of water and food scarcity can undermine basic livelihoods and exacerbate social tensions.
• Rising Water Pollution:
  • There is a large amount of domestic, industrial, and mining waste that is discharged into water bodies, which can lead to waterborne illnesses. Moreover, water pollution can lead to eutrophication, which can significantly impact aquatic ecosystems.
• Overexploitation of Groundwater:
  • 256 of 700 districts in India have reported critical or overexploited groundwater levels according to the most recent study of the Central Ground Water Board.
  • A NITI Aayog report says that India is suffering from the worst water crisis in its history, citing that, 21 cities- including Bangalore, Delhi, Hyderabad and Chennai- probably exhausted their groundwater resources in 2021
  • Wells, ponds and tanks are drying up as groundwater resources come under increasing pressure due to over-reliance and unsustainable consumption. This has escalated the water crisis.

• Swachh Bharat Mission.
• Jal Jeevan Mission
• National Water Policy, 2012
• Pradhan Mantri Krishi Sinchayee Yojana
• Jal Shakti Abhiyan- Catch the Rain Campaign
• Atal Bhujal Yojana
• Sujalam 2.0
• Amrit Sarovar Mission

Q. What is the Way Forward?

A. 

• With climate change and population growth leading to increased water use, new solutions have to be conceived for better urban water management. More people in different local contexts need to be made aware of the challenges.
• Similarly, there are changes required in institutions like local departments that play a crucial role. It is essential that holistic and systemic solutions are implemented to solve water issues.
