Central Ground Water Board (CGWB) has taken up Aquifer Mapping and Management Programme (NAQUIM)since 2012, under the scheme of Ground Water Management and Regulation. NAQUIM is aimed to delineate ·aquifer disposition and their characterization for preparation of aquifer/ area specific ground water management plans with community participation. The management plans are shared with the respective State Governments for taking appropriate measures/ implementation.

Out of the total geographical area of around 33 Lakh Sq Km of the entire country, an area of around 25 Lakh Sq Km of mappable area has been identified to be covered under NAQUIM programme. So far, an area of 24.57 Lakh Sq. Km (as on 30 Dec 2022) has been covered under the programme. The remaining areas are targeted to be covered by March 2023. State/UT wise area covered under NAQUIM studies are given at Annexure I.

Water being a State subject effective use of treated waste water for conserving fresh water resources falls under States’ mandate, however, Central Government has initiated a number of steps in this direction. The important measures in this regard are given as under.

(i) National Water Policy (2012) formulated by this Department advocates for reuse of urban water effluents from kitchens and bathrooms, after primary treatment, in flush toilets ensuring no human contact. Further, NWP advocates that Industries in water short regions may be allowed to either withdraw only the make up water or, should have an obligation to return treated effluent to a specified standard back to the hydrologic system.

(ii) Central Ground Water Authority (CGWA) has been constituted under Section 3(3) of the "Environment (Protection) Act, 1986" for the purpose of regulation and control of ground water development and management in the country. The latest guideline for control and regulation of groundwater extraction with pan-India applicability was notified by the Ministry on 24 September 2020. Guideline stipulates that the requirement of water, with respect to all industries (wherever feasible), for greenbelt (horticulture), shall be met from recycled / treated waste water. Further, it states that installation of Sewage Treatment Plants (STP) shall be mandatory for new infrastructure projects, where ground water requirement is more than 20 m³/day. The water from STP shall be utilized for toilet flushing, car washing, gardening etc. Further, guidelines stipulate implementation of dual water supply systems in infrastructure projects.

(iii) A national framework for the reuse of treated waste water has been published by the National Mission for Clean Ganga (NMCG) The framework gives guidelines for the formulation of State reuse policy and is intended to build appropriate market and economic models for the reuse of treated waste water.

(iv) Thermal Power Plants (TPPs) are required as per Ministry of Power's Tariff Policy-2016 to use treated sewage water from STPs operated by municipalities or, other local authorities within a 50 km radius.

(v) Ministry of Housing and Urban Affairs through Atal Mission for Rejuvenation and Urban Transformation (AMRUT) is supplementing the efforts of State Government to provide safe and clean drinking water in urban areas. The recycle / reuse of used water is one of the focus area under AMRUT in 500 selected cities. Through AMRUT projects, 2,840 Million Litres per Day (MLD) sewage treatment capacity has been created so far, of which 1,437 MLD capacity has been developed for recycle/reuse. State-wise detail in this regard is given at Annexure II.

(vi) AMRUT 2.0 (FY 2021-22 to 2025-26)aims to make towns / cities ‘water secure’ with focus on recycle/ reuse of treated used water, which is an admissible element of projects. So far, through AMRUT 2.0 approved projects, 2,795 MLD of sewage treatment capacity creation is planned of which 1,126 MLD is planned to be recycled or reuse.  State-wise detail in this regard is given at Annexure III.

This information was given by the Minister of State for Jal Shakti, Shri Bishweswar Tudu in a written reply in Rajya Sabha today.
