            Maejo University has a 75,000-cubic meter raw water pond that supplies water for Treatment Plant 1; a 20,000-cubic meter pond that supplies water for Treatment Plant 2; a 32,200-cubic meter pond that supplies water for Treatment Plant3; a 60,000-cubic meter pond that is used for agricultural purposes; as well as the Mae Faek-Mae Ngat Somboonshon Operation and Maintenance Project and natural canals running through the university. Currently, there are sufficient surface-water ponds for both the water supply system and agriculture.

            Maejo University has a pipe system that sends wastewater from all buildings to treatment plants and send the treated water by pipe system to 11 distribution points (as illustrated by the R1-R11 dots on the map). Three of the distribution points further move the water to ponds at seven different points, which are regulated by valves, and one additional point into the natural canal in the university. The 11 distribution points supply water for usage in agriculture and in the forest garden. Virtually all of the wastewater that undergoes treatment in the dry season is used. Meanwhile, approximately 60% of the treated wastewater is used in the rainy season (around 4 months), since there is sufficient rainfall in cultivated areas— resulting in some treated wastewater flow to the natural canal.
