Water management is an important factor for the University. Therefore, the University has a policy to promote and support students and staff to aware of conservation of energy by set campaign, project and activity on energy conservation. In addition, put more effort on operation of underground water storage ponds, wastewater treatment, and water recycling. Moreover, using of energy saving electrical appliances so that students and staff will change behavior of energy consumption and reduce the use of the wrong equipment which waste energy.

       The Sustainable Development Goals, or SDGs, also known as the Global Goals, were adopted by all united nation members. The SDGs are integrated,universal and transformative—that is, they recognize action in one area that will affect outcomes in others, and development must balance social, economic and environmental sustainability. Simultaneously, UI GreenMetric World University Ranking is one of the most important organizations which believes that many universities around the world have strong efforts to implement environmentally friendly and sustainable policies and programs. In 2019, the UI GreenMetric World University Ranking has the major important topic which involves the SDGs “Sustainable University in a Changing World: Lessons, Challenges and Opportunities”. The subtopics can be described from Kasetsart University’s concepts as following: Lessons–This suite of lessons looks at the environmental threats to the planet and provides plenty of involving interactive tasks to help people in community understand how they can live more sustainable lives. Particularly, the lesson is defined as one of the most significant procedure to transform the community. Hence, the lesson is one of the most important practices that the university always realizes. Challenges– – Basically, sustainable development is a long- term solution to how the university plans indefinite progress in the future without causing damage to the environment so as to guarantee a safe habitat for the next generations who will continue to develop their economies, societies, and care for the environment with a similar ideal in mind. This satisfies the needs without sabotaging the opportunities of others. The concept covers a broad scope of matters such as environmental, social, and economic development which continues to prove its importance in our lives as it affects all aspects of them. 

       The challenges are so necessary in current environment and they can help in living a more conscious and altruistic life. Kasetsart University has an effort to conduct knowledge resources by integrating with agricultural, environmental management and so on. Opportunities— The Sustainable Development Goals present a unique and critical challenge for universities around the world. But they’re also bringing to light some of the biggest investment opportunities in a generation. There are big opportunities for purposeful development in the universities’ community. By finding better solutions to some of the challenges which are not only helping to achieve the SDGs; they are also opening up substantial growth opportunities, because they are meeting an unmet need and tapping into long- term demand drivers. From the three significant subtopics are the university’s intentions which are steadily and regularly concerned to construct identity of community in Kasetsart University. As it was mentioned earlier, Kasetsart University has intentionally concerned in what the world has being faced and what the university have to necessarily do. Continuously, there are many university’ s policies that relate to enhance quality living of all people in the university and community around us. The mentioned policies earlier, they are called “Three Paradigms of Transformation” which are the main concerns for developing the university. The paradigms are the key elements to integrate people’ s cooperation surroundings the community and in Kasetsart University. Firstly, the first paradigm is determined as “ Public Service” which is a significant service intended to serve all members of the community. Latterly, the second paradigm relates to Social Engagementwhich includes activity, interaction, social exchange, and lack of compulsion. The university has built the continuum of community commitment to develop this paradigm such as transactional, transitional and transformational engagement. 

       And the last paradigm is defined as “Agricultural Innovation” which means working process with leading agricultural researchers, businesses, landowners, and farmers to develop the knowledge and technologies that will make modern farming more sustainable, resilient, and productive. Through practical and interactive workshops, farm walks, and on- farm demonstrations, this will help the community to put knowledge into practice. Furthermore, Kasetsart University always realize in constructing a happy, vibrant community, and also making strong social connections that create a sense of belonging. And along with belonging comes a sense of responsibility to support each other. With a strong sense of belonging and knowing other community members will take care of each other comes a sense of peace, security, and meaning. Consequently, the “Three Paradigms of Transformation” are the major factors that can be seen in Kasetsart University’ s activities.

        In response to important master plan issues of the 20-year water resource management, both public and private sectors have increased its role in terms of supporting water conservation activities. The awareness of increasing importance of water conservation is established. Therefore, projects and policies of Kasetsart University have been supported in terms of budgets and cooperations from various organizations. It is clear that resulting in variety of campaign activities both in innovation and academic, and increasing awareness of the problem. Guidelines for project development in a variety ways are increasing in the future. 

4.1.2 The project of water storage in different areas of Kasetsart University. 

       Thailand is a country that mainly engages in agriculture. Therefore, there is an area that is high level of necessary to use water for agriculture. Due to fluctuating rainfall or climate change, some areas still face the problem of water shortage. 

Public Service :

       Kasetsart University has realized the importance of the said problem. Therefore, the University has determined a policy to build an area to store water for using of the university and nearby communities, including a campaign to use treated water or water from natural resources instead of tap water. This is in accordance with the main objectives of the energy conservation policy of Kasetsart University as for the reduction of tap water usage and increasing of proportion of reused water, and reducing water shortage problems in nearby areas. This is to ensure that water consumption is balanced with the amount of contained water in that area both present and future. There have been drilling of 9 artesian wells scattered in various areas of the Faculty of Agriculture at Kamphaeng Saen campus for sharing to use in agricultural areas which belonging to Kasetsart University and areas of nearby communities. The artesian wells can pump 156 cubic meters per hour of groundwater and then packed into 5 storage ponds built to hold water, with a total capacity of 32,000 cubic meters. A groundwater storage tanks were built in the area of residence of personnel and nearby communities which working within agricultural area in order to collect groundwater that is pumped from the artesian wells and distributes to the personnel building in the area of the campus, as shown in the picture.

[Figure The storage ponds were built to contain water which pumped from the artesian wells, thendelivered to underground pipes for using in plantation.]

[Figure The storage tank which pumped water from the artesian wells and delivered to the residencearea of personnel.]

       Kamphaeng Saen Campus drills storage ponds to contain water for various uses in the area of the campus and surrounding area. The purpose is for consumption and supporting agricultural activities and raising animals around the campus. There are 7 storage ponds built to store water in Kamphaeng Saen campus area, total area of 416 rai, as shown in the picture. 

[Figure A map of the 7 water storage ponds within Kamphaeng Saen Campus.]

       The Number 1 pond is the largest pond, which a total area of 150 rai, uses to store treated water, then to produce tap water with an average production volume of 48,000 cubic meters / year for using within the campus. All tap water is used in Kamphaengsaen campus produced from pond number 1 (as shown in the picture)

[Figure The Number 1 pond use to produce tap water to consumption within Kamphaeng Saen Campus.]

       Aside from producing tap water in Kamphaeng Saen campus area, there are 6 storage ponds that are used to store rainwater and treated water for other usages that support various activities of the university, such as teaching and learning activities, farming, raising animals including reserving water for use, in order to prevent water shortage in dry season etc.

       7 reservoirs were drilled in the area of Chalermphrakiat Sakon Nakhon Province Campus to contain rain water for using in the campus and surrounding agricultural area, such as Sakon Nakhon, Kalasin, Nakhon Phanom, Mukdahan, Nong Khai and Udon Thani (North and South). All 7 reservoirs can contain approximately 1,400,000 cubic meters of water as in the picture. [Figure A map of 7 reservoirs in the area of Chalermphrakiat Sakon Nakhon Province Campus.]

       After Kasetsart University has allocated enough water resources, then a policy to build a delivery system of treated water or natural resource water to use in different areas thoroughly and most efficiency. There is a system to deliver water from reservoirs to use in many areas as follows: There are 2 ponds for retaining of rainwater for agricultural activities, in front of Suwanvajokkasikit Research Station, the Faculty of Agriculture in Nakhon Ratchasima province. Both ponds are used to retain the amount of rainfall throughout the year in order to use in agriculture area, including to pass through treatment system for consumption inside the station. The university has set up a system to manage the direction of the rainwater flew into drainage pipes around the area and then transported into a water storage tank built for further use as in the picture.

[Figure The water flow system goes down together to the drain and store in a water tank.]

       Two drilled ponds, for retaining of rainwater in agricultural areas within the Faculty of Agriculture, Kasetsart University, were built to retain rainwater that falls each year and to be used in nearby area with a capacity of 10,000 cubic meters.

[Figure The drilling ponds to collect rainwater for agricultural areas inside Suwanvajokkasikit ResearchStation of the Faculty of Agriculture, Kasetsart University.]

       Agricultural innovation Kasetsart University has a policy on water conservation. The rainwater tanks have been installed in various buildings for reuse. It has been divided into two categories: rainwater contained in a sterilizing tank ready to place a pipe directly from the tank for toilets using, and the one that can be used without disinfecting used in various activities, such as watering plants, cleaning areas of buildings, washing cars, etc. (as in the picture)

[Figure Rainwater storage tanks for using in departments within Kasetsart University.]

       Office of Kasetsart University Library has installed rainwater retaining system to store water for vegetables planting inside the building. In which personnel of the Office can consume these vegetables in their households. Considered as another way to reduce household expenses, as in the picture.

[Figure Installation of rainwater retaining system to store water for vegetables planting inside thebuilding of the Office of Kasetsart University Library.]

       There is a water pump installed on the 1st floor of Vibhavadi Rangsit Parking Building which has some cultigens on the 6th floor (rooftop). A water supply system from a storage tank to water the vegetables has been installed and also sunlight can reach to them. Therefore, vegetables can be grown and it is beneficial to personnel of the department (as in the picture).

[Figure Pumping water of Vibhavadi Parking Building to pump water up from treatment pond tovegetable on the 6th floor.]

       Ngamwongwan Parking building 2 within Kasetsart University Bangkhen Campus has installed an underground tank to reserve rainwater for use. The advantage of installation an underground tank is to prevent subsidence that may occur in the area and space-saving installation as well. Also, the underground tank causes the stable temperature of the contained water because it is not exposed to the outside air directly (as in the picture).

[Figure Underground water tanks at Ngamwongwan Parking building 2 within Kasetsart University.]

       Due to Sriracha Campus is located on the area of mountainous terrain with a high slope. The Faculty of International Maritime considered the benefits from the physical characteristics. Therefore, the Faculty had built a waterway system that transports rainwater that flows from highlands to store in wells which built within the faculty’s area for using in education that require to test ships in the field of shipbuilding engineering, etc. (as in the picture).

Social engagement :

       The benefits of water retention are not only good result for the resource management system within Kasetsart University, but also nearby communities, both in the field of agriculture, livestock, and so on. Therefore, communities nearby and the University collaborate to look after surrounding ecological conditions. The increasing of interaction that intends to sharing problems, experiences and suggestions between personnel of the University and villagers. As mentioned above, it can develop the relationship between the university and the surrounding community (as in the picture).

[Figure Nong Han Noi Lotus Park at Sakon Nakhon reservoir is an important tourist destination of Sakon Nakhon Province.]

Results :

       Building water storage and natural water resources such as rainwater, groundwater, including treated water used within these parts can reduce the shortage of water used for consumption as well as in agriculture. Also engaging with villagers nearby areas in terms of cooperation, creating a water management system that are favorable to one another. Causing the use of water from natural sources to benefit Great value. 

Challenges :

       Kasetsart University constructed water reservoirs to provide enough water for consumption and also plans to improve the quality of water including increasing the value of treated water in order to be able to use as utmost benefit, while plans are made to create a database of water resources for using to analyze used water situation to compare with reserved water. As well as, the University having plans to develop the area around reservoirs as tourist attraction and to increase public relations to be a tourist attraction of the province which will help to promote occupational opportunities for nearby villagers. 

Opportunities :

       The government has set up a master plan for water resources management to support the country’s water strategy for 20 years. Therefore, Kasetsart University has implemented the policy, in accordance with the strategy of constructing reservoirs to ensure stability. In addition, increasing efficiency of water resource project. When the policy is driven as same direction as the government, the management of water storage areas will be more efficient.

4.1.3 A policy on water-lavishness reducing and waste-water reduction in the departments

Social Engagement :

       The students of the Faculty of Engineering and expert team collaborate with checking up the condition of the water pump installed in various areas that affect the irrigation systems within Kasetsart University so that the water pump is extended and is ready to use the reducing wasting of time and cost to repairs can be used efficiently. Besides, every pump has record of use history, as well as the complete maintenance period. There are check up and maintenance schedule (as in the picture).

[Figure Experts check the pump system to be able to use fully efficiency]

Agricultural Innovation :

       Kasetsart University has widespread innovation of water-bottle replacement in the toilet tank. It has been used within various departments, so that it can help to reduce the amount of used water in each flushing toilet. 2-3 bottles of water were put inside the water tank at the back of the toilet, then close the water tank lid as normal which can reduce the amount of water that was used in every flushing. The replacing method does not obstruct the water system in and out of the tank. However, this method can save up to 3 liters of water per once use (as in the picture).

[Figure An innovation of water bottle replacement in the toilet tank.]

       Kasetsart University has taken action on reducing water consumption by using the easy-digested toilet paper instead of using water from a spray hose. The objective of this action does not adversely affect the environment and reducing water loss (as in the picture).

[Figure Reducing water consumption by using the easy-digested toilet paper.]

Results :

       Using of innovation or new concepts to response to the water conservation policy of Kasetsart University significantly reduces water consumption and also helps to facilitate the use. In addition, the drainage system that has been checked and regularly maintained can reduce the problem of flooding and water clogging very well. 

Challenges :

Therefore, Kasetsart University is planning to take this opportunity to utilize tools and equipment checking up process, which related to the university’s irrigation system including using of technology to develop new innovation to the existing systems more efficiently for water saving in the future.

4.1.4 Using of innovation from research integrated with water conservation activities in working section. 

       Kasetsart University is an institution that has ongoing research for sustainable development in various fields. The University’s courses are focusing on both industrial support and agricultural growth. Many researches can be practical use and observably developed in terms of water conservation. 

Agricultural Innovation :

       Kasetsart University has a policy to treat wastewater by using bio-fermented water, to comply with the energy conservation policy. According to some water resources in the university that has flooded, causing waste water. Therefore, Kasetsart University uses bio-fermented water which was developed by researchers to solve problems. The positive effect on the community is concerned and enhanced. There are microbes in bio-fermented water that have the ability to help the decomposed organic residues. that can improve water quality, and treat wastewater caused by various activities and also stop various odors in water sources or drainpipes, including unwanted smell from sewers around buildings. The fermented water production can also reduce wet wastes that are generated from departments as well (as in the picture).

[Figure Treating wastewater by using bio-fermented water.]

       Problems of drainage in various areas are also caused by a large number of weed species that clogged the drainage including a problem of ecosystem of water resources. At present, propagation of water hyacinths is a big problem that causes widespread damage to the ecosystem both causing sewage and obstructing water flow. Kasetsart University has a policy to eliminate weeds around water resources. A responsible units were appointed for monitoring and removing of weeds along water sources in order to maintain quality of water in natural sources to prevent spoilage due to weed growth (as in the picture).

[Figure Eliminate weeds around water resources.]

       Kasetsart University researches on a project to eliminate water hyacinths by using fungi. The use of mold or suspension of fungus to spray on water hyacinths that cover water sources, to control the propagation of water hyacinth. This can reduce the impact on environment instead of using herbicides. The properties of the fungus will cause water hyacinths to burn on the leaves and spread to the death of the whole tree. It does not only helps eliminate all hyacinths and add oxygen to water but also reduce the obstruction of waterway. In addition, Fungi, which is a natural method, can also improve water more clarity. This is the result of the scientific processes of researchers at Kasetsart University. Water in canal is more clean and can be used for more benefits such as floor cleaning, plants watering, and truck washing etc. (As in the picture).

[Figure Eliminate water hyacinths by using fungi.]

Social Engagement :

       The research has been cooperated between the Department of Science, Faculty of Liberal Arts and Science ; and the Department of Plant Pathology, Faculty of Agriculture of Kamphaeng Saen Campus which funded by the National Research Council of Thailand (NRCT), while also receiving a part of the research budget from the government. That is likely to be further developed for use at the national level. 

Public Service :

        The innovations which were developed by researchers at Kasetsart University widespread to nearby communities. The bio-fermented water has been distributed to people who are interested in developing the water sources nearby their residence including consulting services on the stopping of water hyacinth propagation in nearby areas. The impact of these innovations are biological safety and do not affect the environment. 

Results :

       Water sources that have been treated by innovation can be used to do more activities. The number of water hyacinths, that is problematic to water sources, decreases including the University has more interactions with other nearby communities. 

Challenges :

       Kasetsart University plans to establish a center for consulting the treatment of wastewater by using the innovation of fungi from water hyacinth, which is a research of the university personnel, including educating to those who are interested in making bio-fermented water for wastewater treatment of their household. 

Opportunities :

       Kasetsart University has carried on government policy on water resources management and conservation, especially in Nakhon Pathom and Sakhon Nakhon. Having realized social policy, a university operates all projects on the concept of sustainability and also promotes agricultural technology system to KU students, staff, and the neighboring community to realize water resources preservation and water use efficiency as well as increase an amount of recycled water usage in all campus and the neighboring community. 

Remark : All activities in 4.2 refer to the Sustainable Development Goals (SDGs), otherwise known as the global goals, especially relating to Goal 6 : Clean Water and Sanitation which Improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally Another significant target of this goal is to Protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lake

4.3.1 Efficient electrical equipment

       Kasetsart University has realized the onset of drought conditions as the prolonged dry season drags on, and has therefore thought about the concept of water saving in agriculture in the most suitable growing conditions for healthy plants. It found that irrigation technology is a solution for agriculture because the technology has supported water-saving and water use efficiency as well as retaining moisture in the soil and helping agriculturists produce quality products to meet the needs of the market. Moreover, it has gathered the technology and cooperated with the neighboring community for exchanging a knowledge of plant irrigation in the concept of water-saving and water use efficiency. Hence, to reach the goal of reducing water in all campus, a university has implemented by using the irrigation technology in terms of suitable growing conditions and water use efficiency, for example, using linear irrigation that can control working functions with electrical battery and computer system.


       Faculty of Agriculture [Suwan farm] has used linear irrigation to corn and millet; this irrigation is suitable for large agricultural area because it can be controlled the working with application system. In addition, a university provides a training in irrigation technology to agricultural network. 


       Kasetsart University, Kamphaeng Saen Campus has installed sprinkler pump that has automatic water feeding system for water saving.


Public service:

       Kasetsart University, Sakon Nakhon campus has built local community network and has also exchanged knowledge of resources management with the community in order to develop the area through taking irrigation technology to meet the needs of the community and to reduce drought. 

Agricultural innovation:

       Kasetsart University takes an innovation of irrigation technology and gives a chance to the neighboring community to study the activity such as how to save water with efficiency, balance the soil, store water for dry season, and help agriculturists produce quality products to meet the needs of the market, resulting income earned and produce products all year. 


       Kasetsart University has planned to extend the community network so as to give more opportunities to locals to learn irrigation innovation, and to promote community participation as well as to find out new innovation for water use efficiency. 


       Kasetsart University has cooperated with more government agencies in order to campaign on water management, promote community participation and take new agricultural innovation applied to communities for social sustainability. 

4.3.2 Water-saving washing system

       The university has a policy on water management for sustainability and has therefore introduced sanitary ware with flushing system that save a lot of water caused by the principle of using new water instead of old water for washing, which not only using a small amount of water but also quick cleaning. The push button for flushing system is on the top of the water tank with two buttons; they can save up to 3 liters of water. And for the automatic flow stop system of the sink and urinal for men, when pressing the button, the water starts flowing for a moment and then stops flowing automatically. This can reduce water consumption more than 75% as follows. [in the Figure 4.3.2] [Figure4.3.2 Water-saving washing system, Automatic flow stop system]

4.3.3 Sensor system

       Can detect motion and turn on-off lamps and fans automatically. Wash basin- tap sensor system flows automatically and the flowing water is going to stop immediately when hands are pulled out. The urinal sensor system will have water flowing when someone stands. If there is no standing man, the flowing water will stop immediately. This can reduce water consumption more than 75%. [in Figure 4.3.3]

 [Figure4.3.3 Motion sensor system and wash basin-tap sensor system]

Public service:

        The university has a water management policy, campaigning for KU students and staffs to use water efficiently and maximize benefits for sustainability. In addition, it increases more convenient through introducing sanitary ware with motion sensor system to facilitate the disabled people and the elders who come to use the service. 

Agricultural innovation:

       The university has chosen sanitary ware that saves water as the main purpose. In addition, there is an innovative water sensor system use in water closet so as to save electricity and water via stopping the operation of electrical system and the water flow. 


        Kasetsart University realizes an importance of bringing new technology or innovations to develop the university in the future as well as encourages all campus use electrical devices efficiently in order to reduce energy consumption, save water and future budgets. 


        Kasetsart University is going to increase an innovation on efficient electrical equipment in the future in order to reduce electricity bills and save resources as well as to support the public who come to use the service within the university to get more convenient. 

Remark : All activities in 4.3 refer to the Sustainable Development Goals (SDGs), otherwise known as the global goals, especially relating to Goal 6 : Clean Water and Sanitation which Support and strengthen the participation of local communities in improving water and sanitation management.
