Recharging water, recharging hope: How Managed Aquifer Recharge system is saving the parched Barind Tract
An initiative funded by the Green Climate Fund (GCF) turns rooftops into ecological recharge zones, aligning local action with the Bangladesh Delta Plan 2100. As a direct access entity (DAE) of the GCF, PKSF leads the initiative.
In the sunbaked expanses of Bangladesh's High Barind Tract, where climate change has pushed the groundwater table to historically low depths, a silent infrastructure revolution is underway. Local communities, once plagued by chronic dry-season water scarcity, are now replenishing their own underground aquifers using rainwater captured from institutional rooftops.
Through the implementation of innovative rooftop Managed Aquifer Recharge (MAR) systems, the Extended Community Climate Change Project-Drought (ECCCP-Drought) is providing a blueprint for localized, climate-resilient water management. Funded by the Green Climate Fund (GCF) and implemented by the Palli Karma-Sahayak Foundation (PKSF), the initiative directly supports Bangladesh's national vision for a climate-resilient future as outlined in the landmark Bangladesh Delta Plan (BDP) 2100.
A Hotspot in Crisis: The Barind's Water Struggle

The High Barind Tract (HBT) encompassing Rajshahi, Chapainawabganj and Naogaon districts is officially categorized as a severe dry region. Under the Bangladesh Delta Plan 2100, the "Barind and Drought-Prone Areas" hotspot (spanning about 22,848 square kilometers) is prioritized as highly vulnerable to rising temperatures, shifting monsoon patterns, and rapidly depleting groundwater tables.
Unprecedented irrigation demands and a historical lack of rainfall have depleted the shallow upper aquifers. During the dry months, the natural recharge from local rivers stops entirely as they dry up, creating a massive structural water crisis that threatens local agriculture, hygiene, and daily survival.
In response, the ECCCP-Drought project collaborating with partner organizations of PKSF has rolled out an innovative decentralized solution.
Harvesting the Monsoon: How Rooftop MAR Technology Works
Instead of relying on expensive and space-consuming surface tanks, the ECCCP-Drought project capitalizes on the earth's natural geology, converting aquifers into secure underground reservoirs. The four-step filtration and recharge cycle work as follows:
Water Collection (WC): Rainwater is harvested from large institutional and household rooftops.
Water Filtration (WF): Water is channeled through engineered sand-and-gravel filtration chambers to eliminate dirt and turbidity.
Water Injection (WI): The filtered water is safely directed into underground aquifers through specialized injection borewells.
Water Storage (WS): The earth's natural, permeable layers store the clean water underground without evaporation losses.
The results of this decentralized infrastructure are highly encouraging:
- A collective catchment footprint of 139137 m² has been created, utilizing an average of 200 m² of rooftop area per structure.
- Approximately 105471 m³ of rainwater was filtered and injected directly into the aquifers during the 2025 rainy season.
- On demand, 500-liter localized plastic storage tanks have been integrated into the system arrays to provide immediate drinking water access for local communities.
Aligning with National Policy and Vision
The National Water Policy: Bangladesh's peak water strategy strongly advocates for "assisting the natural processes of groundwater recharge" to combat over-exploitation and secure long-term resource sustainability.
The Bangladesh Delta Plan 2100: The BDP 2100 emphasizes freshwater preservation, water safety, and adaptive delta management in drought hotspots. The MAR initiative serves as a decentralized, low-maintenance model that aligns perfectly with these national goals.
National Adaptation Plan (NAP): Promoting low-cost, nature-based technologies that can be easily managed by local communities without highly skilled labor is a core pillar of Bangladesh's climate adaptation roadmap.
Turning the Tide: Unexpected Environmental Gains
Beyond replenishing depleted water tables, the MAR systems have brought an unexpected environmental benefit to the region. The injection of rainwater has started improving the localized water availability of the shallow aquifers. By reducing the risks of naturally occurring harmful substances in the groundwater of this region, the systems have accelerated the delivery of water much faster than originally projected.
Community Spotlight: Rohonpur Govt. A.B. High School, Chapainawabganj
Like other areas, the dynamic impact of this technology is highly visible at Rohonpur Govt. A.B. High School in Gomostapur, Chapainawabganj. Despite its academic reputation, the school historically suffered from water insecurity.
To address this, a rooftop MAR system is installed at the school. Utilizing a massive 3,860 m² rooftop catchment area, the school's system has already successfully injected more than 9,000 liters of rainwater into the local aquifer while maintaining full immediate storage capacity.
"After the installation of the MAR system, all the students and teachers of this school are experiencing visible improvement with water availability and quality. Students now collect drinking water directly from the storage water tank. It has created access to water in all the seasons and lessened the burden for all."
Scaling Up for the Future
As the project moves forward, PKSF and its partner organizations plan to carefully monitor the injection metrics through the upcoming monsoon seasons. In close coordination with local administrations, the project management team is working to secure localized ownership and explore opportunities to replicate the MAR model across other public buildings. By successfully demonstrating that climate-resilient water infrastructure can be cost-effective and highly impactful, the ECCCP-Drought project is showing how Bangladesh can turn the tide against climate-induced drought, one drop at a time.
