AIT Waste Water Treatment Plant

The Waste Water Treatment Plant (WWTP) of the Asian Institute of Technology with operation capacity : 1500 m3/day was constructed in 2012 by the Ranhill Water Technologies (Thai) LTD (RWTT), with the concept of BOT (Build, Operate and Transfer) Agreement.  As per the agreement dated 22 June 2011, RWTT would construct the plant, operate and maintain the plant duirng the payback period. The construction of the AIT WWP completed on 18 July 2012. Since then Ranhill has been runing the plant to treat waste water collected from AIT campus. On 1 January 2019 the waste water treatment plant ownership was transfered from RWTT  to AIT.  Since then AIT contracted RWTT to operate and provide maintenance service.

The WWTP collects the waste from the AIT campus both residential and academic area through 13 sewage pump located through out the campus and the treated water from the WWTP are then pumped back into the AIT canal system. The canal water in turn are used for watering the plants through out the campus through sprinkler system. And treated water helps to maintain the water level in canals and there by also helps to maintain aqua ecosystem in canals in dry season.
