Clean Water and Sanitation

Water usage and care

KMITL has 2 septic tanks in which each tank is connected to an aerated lagoon. It is a simple wastewater treatment system consisting of a pond with artificial aeration to promote the biological oxidation of wastewater by using aerators to mix the contents and add oxygen to the pond. It is an efficient and cost-effective system for primary and secondary wastewater treatment, low maintenance, and reliable treatment. Treated water is collected in many reservoirs in the institute and mix with rainwater from our drainage system again. Each reservoir also has aerators for oxygen adding to improve water quality. Treated water is used for watering the tree in the institute, and some of them are discharged into the public sewer.

We rely on green space and unpaved area as the natural filtering and treatment system for stormwater runoff and polluted water before entering natural water bodies. We ensure to have the maximized area for water absorption. In 2018, there was an approximate total of 40% of campus area as green and water absorption space. We also have several retention ponds on campus for receiving polluted water by accidents and incidents.

Free drinking water

The institute also provides free drinking water for students, staff, and visitors by setting drinking water tanks in all canteens, the Central Library, and all departments in KMITL, while promoting personal water container campaign to fill up free drinking water at any of the service points. This facility

supports good health, well-being, good hygiene of everyone, and also reduce plastic waste in our campus area.

Minimise water usage

KMITL follows the Thai’s Rating of Energy and Environmental Sustainability (TREES) building standard of the Thai Green Building Institute (TGBI), which is a certification body for energy-efficient and environmentally friendly buildings according to the green building standard. We are currently constructing two new buildings, the Hitech Building, and the new Faculty of Education building. The buildings have won the Energy Efficiency Building Award 2018 in the silver rank. In terms of water saving, we have focused on both water-saving and water efficient consumption. We have used water- efficient appliances wherever it is possible. For example, toilet flushes are equipped with flushing sensors, dual button systems, sensor equipped urinals, and automatic taps. The institute’s ratio of water-efficient appliances divided by total appliances is 58.34%.

Our Chumphon campus hosted vetiver grass plant campaign for soil and water conservation around Theen Jub creek and Wat Nay canal in Chumphon province. Vetiver grasses help reducing damages from water flush during rainy season, increasing soil humidity in arid season, acting as a nursing crop for forestation, and soil and water conservation in economic crop plantation. Our students, staff, and also local people were well participated in this campaign.
