The existing water treatment plant has a capacity of 13,200 cubic meters per day. In order to piped water process is run respectively (a figure shown below illustrates the piped water treatment process) in which the latter consists of odor removal, chemical addition, coagulation and flocculation, sedimentation and clarification, sand filter, chlorine disinfection, storage, and finally distribution processes.
The University constructed and installed a water recycling system for reuse in the sanitation and garden sprinkler systems. The sprinklers are used for watering plants to reduce the problem of dependency on raw water when there is lack of water. The treated wastewater has been conditioned to have appropriate qualities for use and meets standard requirements for utility water for recycled water. Each year, SU is able to recycle water at the amount of 317,880 m3/yr. This reduced the use of tap water by 20%. The recycled water is used in the sanitary system throughout 73 buildings accounting for 60% of the buildings in the university. Recycled water is also transported for use for watering plants in 24 garden sprinkler locations throughout the university which is 70% of all the green areas that needs watering.
Suranaree University of Technology (SUT) promotes an installation of water efficient appliances to replace conventional ones. In fiscal year B.E. 2563 (2020), more water efficient appliances have been installed and that makes the total number of them equal 6,129 or 77% of all appliances used in SUT campus. In contrast, only 23% of conventional appliances are found at the number of 1,850.
Suranaree University of Technology (SUT) has 3 water wells with overall storage capacity of 1.50 million cubic meters for harvesting rain and producing piped water, respectively. High Density Polyethylene (HDPE) plates are used for leak reduction and underground water tanks are built at SUT buildings for rain storage. In addition, 4 wells are dug underground to store groundwater at the rate of 20,000 cubic meters per year, reducing the use of piped water by 1.5%.
The university has its own three water production systems and distributes this water through the pipe network for consumption within the campus. The water supply plant sourced from raw water from all reservoirs, capacity 9,600 cu.m./day, producing 1,256,080 cu.m./year Read more
In the water supply production, there will be water sediments which are those discharged from the settling tank (thick water sediments) and those resulted from sand wash (thin water sediments). The water sediments, occurred during the two processes, amount to 13 percents of the raw water fed into the supply water production. Read more
The university has a specific pipe network system to collect wastewater from residential, office, and academic zones to its own water recycling plant. These wastewater flows by the gravity and enter into the wastewater recycling plant which is located at the lowest ground level of the campus area as shown in the Figure. Currently the plant can recycle 393,442 cubic meter per year. Read more
The university has tried to survey for groundwater within the campus area since the surface water supply nearby the campus is deficient. In this region of Thailand, the groundwater is usually contaminated by the rock salt formation. Read more
Promote using sanitary wares by replacing old ones. In fiscal year 2018 (2561 B.E) we have changed the toilet to save water 216 set The proportion of use of sanitary ware, including the campus 7,342 set Calculated as a percentage 77% and traditional sanitary ware. 2,236 set Calculated as a percentage 23% of total sanitary ware
