India’s Latest Rainwater Harvesting Success Stories & Government Initiatives (2025)

🌆 Urban Innovations & Government Initiatives

1. New Delhi (NDMC)

The New Delhi Municipal Council (NDMC) has adopted modular rainwater harvesting pits using crosswave technology. These eco-friendly structures require minimal construction materials and can store up to 95% of collected rainwater. NDMC has developed 272 RWH pits, including 105 modular ones, and plans to install more at 27 major waterlogging points to mitigate flooding and enhance water conservation.  

2. Bengaluru, Karnataka

Despite mandates, around 42,000 properties in Bengaluru remain non-compliant with RWH regulations. In January 2025 alone, the Bangalore Water Supply and Sewerage Board (BWSSB) collected ₹2.7 crore in penalties from such properties. To promote RWH, BWSSB has implemented systems at 3,000 locations, including schools and parks, serving as demonstration projects to inspire broader adoption.

3. Hyderabad, Telangana

The Hyderabad Metropolitan Water Supply & Sewerage Board (HMWS&SB) launched the 'Prathi Intlo Inkudu Guntha' campaign to enforce RWH in all houses with an area of 300 sq. meters and above. From January 2025, defaulters are charged double for each water tanker delivery, incentivizing compliance. T

4. Raipur, Chhattisgarh

The Raipur Municipal Corporation (RMC) constructed over 900 rainwater pits in large residential colonies within two months during the last monsoon season. This community-driven initiative earned national recognition and was showcased at the National Builders Conference as a model for urban water conservation. 

5. Rajasthan

The state's Water Resources Department mandated RWH systems for all new residential buildings measuring 225 sq. meters or more and commercial buildings of 500 sq. meters or more. Non-compliance results in denial of water connections and potential legal consequences. 

🌾 Rural Success Stories

1. Kattakada, Kerala

Under the 'Jal Samriddhi' project, the Kattakada assembly constituency initiated a campaign to construct rain pits in house yards, public spaces, and farmlands. Each pit can store 200 liters of rainwater, and with 100 pits, up to 20,000 liters can be collected, significantly improving groundwater levels in the region. 

2. Giridih, Jharkhand

With support from NITI Aayog, Giridih district renovated 57 ponds, enhancing their capacity to store 67 crore liters of rainwater. This initiative benefited over 1.17 lakh people by improving water availability. 

3. Bantwal, Karnataka

Six women from the Chiguru Sanjeevini Federation constructed over 200 RWH pits to boost groundwater levels. Their efforts exemplify community-driven water conservation in rural areas. 

🇮🇳 National-Level Programs

Jal Shakti Abhiyan

The central government released ₹3,551 crore to Andhra Pradesh under the Jal Shakti Abhiyan over the past three years. In 2024 alone, the state completed 13,519 water conservation and RWH works, renovated 10,814 traditional water bodies, and set up 3,026 recharge structures.

Watershed Yatra

Launched by the Union Minister of Rural Development, the 'Watershed Yatra' campaign aims to generate public participation and awareness about watershed development activities under the Pradhan Mantri Krishi Sinchayee Yojana. Projects demonstrating excellence receive additional rewards, promoting effective water conservation practices.
