KMUTT has implemented over fourteen rainwater harvesting systems across campus, allowing for the collection and storage of rainwater rather than letting it run off. This efficient system not only cuts irrigation costs but also reduces reliance on tap water for plant care, conserving over 136,600 cubic meters of water annually.

To ensure safe and sustainable usage, KMUTT conducts monthly monitoring of the water quality in each rainwater harvesting system. Key indicators such as Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and pH levels are tested to maintain water quality. By managing phosphorus levels and preventing excessive algae growth, KMUTT protects dissolved oxygen levels essential for plant health.

Through rainwater harvesting, KMUTT enhances its green campus initiatives, showcasing an effective and eco-friendly approach to water management.

Goal : 35% of rain water conservation for usage in campus by 2024
Current Status: In 2024, 36.31% of rain water conservation for usage in campus


At KMUTT’s Ratchaburi campus, 100% of the water consumed is supplied by an on-site potable water plant with a production capacity of 5 m³ per hour. The campus relies heavily on rainwater harvesting as the primary water source, significantly reducing dependence on the Metropolitan Waterworks Authority.

This self-sustaining system not only secures a reliable water supply but also contributes to the campus’s long-term sustainability goals. By implementing high standards in water production and distribution, KMUTT ensures both stability and environmental responsibility in its water management practices.

This process exemplifies KMUTT’s commitment to innovative water conservation and resource management, setting a standard for sustainable campus operations.
