Participatory Groundwater Management (PGWM) Program

Participatory Ground Water Management (PGWM) Program in Kachchh district, aims at Water Conservation and Management through intense participatory action research. Key activities include:
Institution and Capacity building including (i) Village level “Bhujal Jankars” with knowledge of hydrogeology, water budgeting and coordinating village level action groups and (ii) Community / Village mobilization through farmer and women groups, and Implementation steps including (i) developing comprehensive Village water security plans (ii) Water storage and recharge structures – building new ones and rejuvenating existing ones, (iii) Demand management initiatives like cropping changes, drip irrigation etc.
In 1st term, focus was on Capacity building and Supply side activities. In the 2nd Term, focus was on Demand side activities and in the current ongoing 3rd Term the focus is to bring technology interventions for smarter supply and demand side management, while continuing to strengthen capacity building.

PGWM has also extended its activities to the Khambhailya, Devbhumi Dwarka Dist., Gujarat, to apply the concepts and develop specific strategies, practices and protocols for another hydrogeological region, that of Coastal Saurashtra. This aims to validate methodology to apply PGWM practices to a another hydrogeological region.

Pilot scale material and system development for Arsenic and Fluoride removal

Development of Janus particle embeddable with chosen biopolymer for eventual fabrication of nano-polymer system for safe water production. Pilot-scale in-situ performance demonstration of nano-polymer equipped groundwater well systems.
IIT Gandhinagar


This research, one of its kind in India, aims to calculate the actual fresh water consumption at household level for various uses like cooking and drinking, bathing, toilets, washing clothes, and its seasonal variations, variations across socio-economic groups etc. Understanding these usage patterns can enable intelligent partial recycling of water within the house or society or community, with partial or no treatment. E.g. usage of waste water from kitchen may be usable in garden, or from washing clothes can be fed to flush toilets. This has potential to reduce the fresh water requirements in houses and communities.

This provides high pathogen removal efficiency at low cost and using very low amounts of any additives like silver-nano particles. The project involves (i) development of 50 prototypes and (ii) preliminary business plan for a venture which can take this technology to social impact markets.

People Say

WIN foundation is supporting Arid Communities and Technologies for a participatory groundwater management project (PGWM) at Kutch, Gujarat, named “K-Marc”... (Kankavati – Managed Aquifer Recharge through Communities). ACT started this project in 2010. It started showing significant impact after six years of initial processes. Now the project learnings and processes developed can help others to adopt climate resilient and community managed groundwater management practices. At this crucial juncture, WIN foundation is supporting ACT and her other project partners viz., Geo-science Services, Parab, Tata CGPL CSR for establishing project area as PGWM field laboratory. The ACT-WIN collaboration has opened many avenues for future, through many collaborations, partnerships, and developing linkages with institutes like IIT Gandhinagar. I am sure that this collaboration will help the project and its various outcomes like Bhujal Jankars, PGWM field lab, Farmer Friendly Groundwater Recharge Techniques, among others, and also to pitch this complete strategy and process at various levels of the society. On behalf of all project partners and stakeholders I am heartily grateful to WIN foundation for this inestimable support.

In CGPL ( Tata Power), we always believe in cooperation, coexistence and cocreation in delivering the best for the community to enhance the community satisfaction.... Our delivery mechanism is based on esteemed partnership with likeminded stakeholders to enable is to jointly address and plan for long term sustainable methodologies. Our partnership with WIN is one of the pioneer partnership, and provides the required momentum in augmenting the water availability in the region through various timebound interventions, encompassing systematic study of the region, calculations and assessment of the water deficit, Activity intervention in the demand and supply side , Institution building and creation of the community knowledge bank, Knowledge dissemination etc. The partnership between CGPL and WIN is based on mutual interest, faith and trust, which is becoming a benchmark of consistent delivery platform in the region and signifying a new paradigm of social development in a sustainable manner through Multi stakeholder partnership approach. Our joint commitment and efforts with appropriate equity investment, involvement of suitable technical and implementing agencies is bringing a substantial change in the region. I always cherish this partnership which can only bring the Change and ultimate transformation in the region on the water front.

Due to benefits to people, demand for K-MARC program (under ACT) has increased. People in the community have accepted Bhujal Jankars and interact with them in respectful manner. Initially it was difficult to explain the program details to farmers.... After the recharge activity demonstrated the benefits to the farmers they started cooperating with us. The demand for ground water recharge also increased and the farmers accepted the importance of role of Bhujal Jankars. The Bhujal Jankar training from ACT included relation between water and ground, Kankavati sandstone acquifer, water quality and quantity measurements, water demand and supply for village and village clusters. We carry out water planning and budgeting, plan and execute recharge structures, monitor water quality and quantity measurements and also help conduct village level meetings for water related issues.

I have a 17 acre farm in Gundiyali village, Kutch. I had a 20 year old borewell which stopped working in 2015. I got a new borewell of 400 feet depth done. This borewell is being used for irrigation in my farm....In 2018-29, i joined the K-Marc program being organised by ACT. Under this program, water recharge system was installed in the old and unused borewell. Due to this recharge of ground water, the water level in my new borewell improved from the earlier 350 feet depth to 300 feet depth. The quality of the water too improved. I also guide my neighbourhood farmers. We all continuously learn new useful practices and techniques in the trainings organised by K-Marc.

VIKSAT partnership with WIN Foundation for implementation of the ‘Anandshala se Jeevanshala’ is an effort to facilitate development of school centered WASH approach and extending it ... to develop a model for sustainable rural water and sanitation for the community in the selected project villages. The demonstration of RRWH and improving environment in schools have a triggering effect, which motivates the community to take up similar work in villages. The efforts are leading to behaviour change at household level and improvement in village environment.

In order to reduce the stress on the existing fresh water bodies, it is necessary to encourage treatment and reuse of wastewater for various onsite purposes inside the IIT Kharagpur campus ... to increase the water availability. The demonstration wastewater treatment plant to produce potable quality treated water after successfully and reliably treating sewage to meet the desired water quality norms with the help of WIN foundation enables IIT Kharagpur to develop a robust, cost-effective and replicable technology, which can be the torch bearing know-how of its kind for the underprivileged part of rural India in near future.
