Water Conservation Program Implementation Suranaree University of Technology (SUT) has 5 water wells with overall storage capacity of 1.85 million cubic meters for storing rainwater and producing piped water later on. High Density Polyethylene (HDPE) plates were used for leak reduction and underground water tanks were built at SUT buildings for rainwater storage. In addition, 4 wells were 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 carries out two following projects to reduce loss of water supply in the campus area. The first project is to replace the leaked water supply pipes made of iron and asbestos cement due to long-time use and the second project is to reduce loss of supplied water in buildings where rust and leakage are detected on water pipes. These two-project implementation decreases amount of water supply by 21.65% compared to the average amount reported in the last 3 years (the average amount of water supply in October-July period of the 2019-2021 fiscal years equals 1,080,537 cubic meters). In addition, the university can increase stored water by 1,500 cubic meters (in vertical storage tank) for use at SUT hospital and other buildings.

During the dry season every year, the university requires untreated water from outside the campus to support the internal use and be stored. Untreated water from Ban Makham Thao water treatment plant is collected (348,313 cubic meters) from September to December. The university also retrieves rainwater from Sura reservoir at the amount of 1,478,000 cubic meters, making the total amount of water stored in the reservoir 1,826,313 cubic meters (from October 2021 to July 2022). However, some water evaporates and is lost from the reservoir resulting in the leftover untreated water as of 31 July 2022 (1,737,737 cubic meters) being 93.93 % of the full capacity of reservoir inside the campus (1,850,000 cubic meters).

In addition, the university implements water-saving measures including installation of water meters at 1,690 sites to analyze water use at buildings which account for 100% water use in the campus, the monthly inspection for water pipe leakage to reduce water loss, the notification of broken, leak, or water pipes via @SUT.SOS Line application for quick response, and the continual publication of water-saving campaign via university media to raise awareness among water users in the campus.
