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.

4.1 Project/activity on water consumption in internal office 

4.1-1 Kasetsart University appointed a committee on energy management to set an overall policy, plan and conduct energy conserva (Figure 4.1-1)

Figure 4.1-1 Appointment of committee on energy conservation.

4.1-2 Kasetsart University has water conservation and energy saving campaign on both poster and website. (Figure 4.1-2)

4.1.8 Rain water saving

– Rain water saving for vegetable watering on the Central Library building (Figure 4.1-8)

Figure 4.1-8 Rain water saving

– Rain is saved in our specific reservoirs for sanitization. A campaign on water saving is developed by using water saving taps. (Figure 4.1-8)

 Figure 4.1-8 Rain reservoir

– The ground water tank has been installed at the Ngamwongwan 2 parking building for protecting the landslide. Moreover, this installation would help the university for space-saving.

4.3 Efficiency usage of electrical appliances

Efficiency usage of electrical appliances can reduce 75% of water consumption in Kasetsart University. 

4.3-1 Dual flush toilet system can save 3 liters of tap water to drain on an idea of new water flow to replace the old one. (Figure 4.3-1)

4.4 From 100 percent of water consumption in Kasetsart University, two campuses, namely: Kamphaeng Saen Campus and Chalermphrakiat Sakon Nakhon Province Campus can produce tap water on their own. 

Information of Tap water consumption (monthly)

Water supply process of Kasetsart University

– High water tower serves to store tap water for consumption.  In addition, it helps to increase the pressure in the pipe line, to deliver tap water to the area of 7,951.75 rai of the campus. Besides, the water is distributed to the community around Kamphaeng Saen Campus. The campus can produce about 4000 m3/day of tap water at 59 meters height above sea level.
