Water Audit (CGWA)

CGWA stands for Central Ground Water Authority, which is a regulatory body under the Ministry of Jal Shakti, Government of India. It was established in 1997 to regulate and control the development and management of groundwater resources in the country. The CGWA is responsible for granting permits for groundwater abstraction, regulating groundwater use, and ensuring sustainable use of the resource. It also monitors the groundwater levels and quality in various parts of the country and takes measures to prevent overexploitation and contamination of groundwater. The CGWA plays an important role in the management of India’s water resources and in ensuring access to safe and clean drinking water for its citizens.

 the water audit is an important tool for ensuring the sustainable use of groundwater resources and protecting the environment from the adverse impacts of over-abstraction and pollution of groundwater.

A water audit also helps in identifying the areas where water conservation measures can be implemented, and helps in optimizing the use of water resources in a sustainable manner. It is mandatory for certain industries, such as mining, thermal power plants, and textiles, to carry out a water audit and submit a report to the CGWA annually.

As per the guidelines of Central Ground Water Authority (CGWA), a water audit is an assessment of the water balance in a particular area or water system. The objective of a water audit is to quantify the total quantity of water available in the area, and how it is being used, including the amount of water being abstracted from groundwater sources, the quantity of water used for various purposes, and the quantity of water being discharged as wastewater.

The water audit report should include the following information:

  1. Water balance sheet: This should include the total water available in the area, the sources of water, and the amount of water being used for different purposes.

  2. Water consumption pattern: This should include the quantity of water consumed for different processes or activities, such as irrigation, domestic use, industrial use, etc.

  3. Identification of areas where water conservation measures can be implemented: This should include an assessment of the potential for rainwater harvesting, wastewater reuse, and other measures that can help conserve water.

  4. Recommendations for sustainable water management: The water audit report should provide recommendations for sustainable water management practices that can be implemented in the area to ensure the long-term availability of water resources.
