The best way to prevent water system pollution is effective wastewater management. The treatment system employs a combination of physical, chemical, and biological processes to remove contaminants, organic matter, and harmful substances from the wastewater. By implementing effective wastewater treatment practices, ITS not only safeguard local water resources and ecosystems but also contribute to a cleaner and safer community.
ITS has a waste treatment system to prevent water pollution. Wastewater management at ITS is regulated in Circular Letter of ITS Rector No. T-95007-IT2-TU.00.08-2019 about ITS’ Initiatives towards Sustainable and Environmental Friendly Campus, item A, where in point 3 it is explained that the ITS community strives to encourage efforts to save water by avoiding unnecessary water use and encouraging efforts to utilize water return of wastewater for watering activities, then at point 9 which is to encourage efforts to manage domestic wastewater by managing and recycling efforts. Waste water management at ITS is carried out through the installation of Anaerobic Baffled Reactor (ABR) Wastewater Management (IPAL) or simple WWTP using grease traps and settling ponds. These are the locations of IPAL:
- Rectorate: Wastewater from restroom urinals, sinks, and floor drains for toilet flushing water.
- Research Center: Wastewater from restroom urinals, sinks, and floor drains for toilet flushing water.
- Departments of Chemistry and Departement of Environmental Engineering: Organic wastewater by laboratory operations.
- Manarul Ilmi Mosque: Wudu wastewater is controlled using storage and aeration ponds and repurposed for watering plants and raw water for fish ponds.
- Department of Mechanical Engineering: Collected in a holding pond and repurposed to irrigate plants.
- Central Canteen: processes wastewater from the central canteen using IPAL ABR.
