Sustainable Water Management at Chulalongkorn University Land Development Project, Saraburi Province

Chulalongkorn University recognizes the importance of sustainable water resource management both within and beyond its main campus. The University has implemented various programs and initiatives to enhance water-use efficiency and promote responsible management of natural water resources located within and surrounding its properties.

One of the key sites exemplifying this commitment is the Chulalongkorn University Land Development Project in Saraburi Province, located in Kaeng Khoi District. The project is administered by the Center of Learning for the Region, Chulalongkorn University and serves as a center for academic services, research, and knowledge transfer to local communities. It also functions as a learning site for agriculture, natural resource management, and sustainable area development. [ https://km.rdpb.go.th/Project/View/6075 ] [ https://clnr.chula.ac.th/ ]

The Saraburi Land Development Project covers a large area where water is essential for various activities—including agriculture, research experiments, and building operations. In addition to using the municipal water supply, the project area has its own reservoir with a storage capacity of 700,000 cubic meters, which supports water supply needs and reduces dependence on external sources.

To ensure long-term water security and management efficiency, Chulalongkorn University has collaborated with the Saraburi Provincial Irrigation Project to develop a Sustainable Water Management Plan, comprising the following key strategies:

1. Reservoir Expansion Project

The University plans to upgrade and raise the crest of the existing reservoir dam, increasing its capacity from 700,000 cubic meters to 2 million cubic meters. This enhancement allows the reservoir to store excess water from the nearby Ban Dong Reservoir, which holds an average of over 5 million cubic meters annually. By capturing more surface water during the rainy season, the project ensures sufficient water availability during dry periods and reduces reliance on the municipal water supply.

2. Gravity-Fed Water Distribution System

A gravity-fed water distribution system is being planned to deliver water from the reservoir to operational zones within the project area. By utilizing gravitational force instead of electric pumps, this approach reduces energy consumption and environmental impact. The system exemplifies sustainable water extraction and distribution technology that conserves energy while providing adequate water for agricultural activities and restoring soil moisture in degraded forest areas—thereby lowering the risk of forest fires during dry seasons.

3. Groundwater Recharge Study

A Groundwater Recharge Potential Analysis has been conducted to assess the feasibility of replenishing underground aquifers. Using Geographic Information System (GIS) technology, suitable areas for groundwater recharge have been identified to enhance the sustainability of water extraction and use. This method helps prevent excessive groundwater withdrawal and maintains the natural hydrological balance of the area.

4. Community-Based Water Management

Chulalongkorn University also promotes community participation in water conservation efforts. The University conducts training and educational programs for local farmers on efficient water use, water quality maintenance, and cooperative water management during dry seasons. These initiatives foster collaboration between the University and surrounding communities, ensuring sustainable and inclusive stewardship of shared water resources.
