1. LPPT Waste Management
The university has a procedure for managing laboratory waste so as not to endanger the laboratory and the environment. This procedure includes procedures for implementing temporary storage of laboratory waste in each laboratory room, temporary storage of all laboratory waste, and further handling.
2. Wastewater Treatment Plant at Academic Hospital
Wastewater treatment data in academic hospitals are accounted for through quality testing by accredited laboratories in accordance with applicable regulations.

The Faculty of Dentistry implemented the IPAL system because environmentally friendly technologies such as bioreactors, membrane technology, and biofiltration are used to process wastewater. The Faculty routinely monitors the quality of the wastewater produced by the WWTP to ensure that it complies with applicable environmental standards.
4. Wastewater Treatment at UGM Bulaksumur Residence with Magic Tank Treatment
Wastewater at the Faculty of Dentistry is under strict control. Wastewater processed by the WWTP will be treated to a safe standard for release back into the environment or even recycled for reuse, such as garden watering and toilet flushing.
Implementing the WWTP system at the Faculty faces several challenges, including limited land to construct adequate facilities, variations in waste from various activities on campus, and considerable operational costs. In addition, laboratory waste containing chemicals requires special handling so as not to pollute the disposal system.

Wastewater treatment in Bulaksumur Residence using the Magic Tank Treatment. The Magic Tank Treatment solved environmental problems such as wastewater from washing activities and bathing in the bathroom that appear in residential areas or residences. At the end of 2019, the wastewater treatment system was installed in Bulaksumur Residence in the scheme of Community Service activities as a pilot application of research results developed at the Faculty of Engineering UGM.
6. Implementation of Water Recycling Program at UGM
The picture below shows the Schematic of The Sewage Treatment Plant (STP) or Biological Treatment Process for Greywater (left) and Schematic of the Water Treatment Process for Greywater (left). Several faculties, including the Faculty of Engineering, have implemented a greywater recycling system.
Some pictures above depict the Ground collector tanks at the UGM residence where the greywater resides after finishing the Water Treatment process until it is needed. Also, The greywater recycling system on the rooftop of Kinanti Residen (one of UGM’s student dormitories) is used for flushing toilets and watering gardens. Rainwater harvesting and recycling tanks at the Faculty of Engineering and at UGM Residence, which are part of the campus rainwater harvesting system.

A water recycling program is the process of collecting, treating, and reusing wastewater for various purposes. Through these programs, we can reduce the need for freshwater and minimise environmental impact. Water from sinks, showers, or stormwater is treated and reused for non-potable applications such as irrigation, toilet flushing, or cooling systems.
UGM has several ongoing water recycling programs.
- Greywater recycling: A system that captures water from dormitory showers and sinks, treating it for reuse in landscape irrigation.
- Rainwater harvesting: A system that collects rainwater from rooftops and reuses it for toilet flushing or garden irrigation. UGM uses both rainwater harvesting systems and ducted rainwater harvesting systems.
- Other water recycling programs include a recycling system for the University Mosque pond, the Faculty of Animal Science, which uses recycled water from the canteen, and UGM, which uses two water recycling methods: upflow and downflow.
The figures above show the water quality control of UGM Valley Lake and the upstream Code River. In addition, the tabular programme shows water quality monitoring data from several locations over the period 2020-2023. The locations are different water bodies, such as rivers and lakes, in and around the UGM main campus in Yogyakarta, Indonesia. The table is organised by year and semester (SEM 1 and SEM 2), displaying the parameters measured at each site.
A table displaying the total coliform count (measured in CFU—colony-forming units) for various water sampling located in UGM over different semesters from 2020 to 2023. Data is used to monitor water quality and safety across these locations, indicating the presence of potential contamination and areas that may need intervention or further investigation.

Regional regulation on domestic sewage water treatment which enforces institutions in the provice of the Special Region of Yogyakarta, including Universitas Gadjah Mada, to dispose the sewage water in their system.
Each semester, UGM sends teams to conduct quality control of the water available on campus.
- UGM monitors and tests the quality of water sources and bodies of water located inside and near the main campus area, such as the lake in UGM Valley, the shallow wells near faculty buildings, and the Belik and Code River.
- In 2023, UGM widened the parameters of their water quality monitoring study, tracking pollution indicators and water health over the years.
- In monitoring water pollution and quality control, UGM refers to regional and national regulations.
UGM Water Quality Test Lab Results
- Universitas Gadjah Mada conducts clean water testing.

The test laboratorium result of water quality in the university results in twenty-one clean water quality samples based on quality standards according to government regulations and management recommendations prepared by a team of Chemical Geophysics experts at the Center for Environmental Studies of Gadjah Mada University. Based on the monitoring results, most of the clean water sources used by UGM have high Total ColiJbrm and E.Coli content. The total coliform content ranges from 1.8-300 CFU/100 ml. while the e.coli content ranges from 1-77 CFU/100 ml. Based on Permenkes RI number 2 of 2023 concerning clean water quality standards for total coliform and e.coli parameters, it is 0 cFU/100 ml.
2. Universitas Gadjah Mada tests lake and river water around the campus

The UGM Campus Environmental Monitoring Plan (RKL) is reported through the test results of four river water quality samples and two lake water quality samples, which were taken by a team of Chemical Geophysics experts at the UGM Center for Environmental Studies. River and lake water quality monitoring quality 2 refers to Permenkes No. 2 of 2023 concerning Regulations for the Implementation of Government Regulation No.66 of 2014 concerning Environmental Health.
