While surface water resources are abundant, groundwater plays a critical role, especially during the dry season when river flows diminish. However, the availability of groundwater varies significantly across the state, influenced by geological formations and topography. In some areas, groundwater is readily accessible through traditional wells and springs, while in others, it is confined to deeper aquifers requiring more sophisticated extraction techniques. The PHED focuses on conducting hydrogeological surveys to assess groundwater potential and develop sustainable groundwater management practices, including artificial recharge techniques to replenish depleted aquifers. Protecting groundwater quality from contamination is also a key priority, ensuring a safe and reliable water supply for future generations. Monitoring and assessment programs are essential components of this effort.

The table above provides a general indication of rainfall and groundwater potential across selected districts of Arunachal Pradesh. These figures are estimates and vary depending on specific locations and microclimatic conditions. Further detailed studies are being conducted continuously to refine these assessments and inform targeted interventions.

The PHED’s Initiatives in Water Supply and Sanitation

The PHED is the nodal agency responsible for providing safe and adequate drinking water to all households in Arunachal Pradesh. This involves the implementation of various schemes and programs, including the Jal Jeevan Mission (JJM), a national initiative aimed at providing functional household tap connections (FHTCs) to every rural household by 2024. The PHED is working diligently to meet this target, focusing on the construction of water supply infrastructure, such as intake structures, treatment plants, and distribution networks. Alongside FHTCs, the PHED also prioritizes improving sanitation facilities, promoting the construction of household toilets and implementing community-led sanitation campaigns. These efforts are crucial for improving public health and hygiene, reducing waterborne diseases, and enhancing the quality of life for the citizens of Arunachal Pradesh.

Community Participation and Sustainability

Recognizing the importance of local ownership and participation, the PHED actively involves communities in the planning, implementation, and maintenance of water supply and sanitation projects. Village Water and Sanitation Committees (VWSCs) are established in each village to ensure community ownership and accountability. These committees play a vital role in mobilizing local resources, promoting hygiene awareness, and managing the water supply systems. Sustainability is a key consideration in all PHED projects. Emphasis is placed on using appropriate technologies, providing training to local communities on operation and maintenance, and establishing viable revenue recovery mechanisms to ensure the long-term sustainability of the water supply systems. The department is also exploring innovative solutions like rainwater harvesting in rural areas.
