To maintain water quality standards within the faculty area, the Faculty of Public Health, Universitas Indonesia has a guideline for water disposal especially liquid waste coming from the Matoa Canteen.
Wastewater from the Matoa Canteen was handled technically using a grease trap, so that oil/fat can be handled separately before being disposed elsewhere by the university’s facility maintenance team. This method was also implemented in other canteens within the faculty area, but the grease trap was in the form of a control tank which is cleaned every day. The faculty also installed a filtration tool to process wash water from the canteens. This tool was installed in October 2023 and was fully used in November 2023 with expected output that the canteens’ wash water can be reused.
Furthermore, the Faculty of Public Health also utilizes liquid waste by having condensation water reservoirs for all air conditioners in the faculty. Condensed water is stored in holding tanks located at 6 points within the faculty, each with a capacity of 1,000 liters which is full within 2-3 days. The water collected in the tanks are used to clean floors and water plants by the faculty’s janitors. Aside from reusing water from the condensation water reservoirs, a rainwater storage treatment plant was also installed within the areas of the faculty. Rainwater collected in the ground tank is channeled through pipes and filtered into clean water, then channeled to the toilet in Building G.
Action plan to reduce plastic waste within the Faculty of Public Health, Universitas Indonesia includes providing a free water dispenser which can be used by everyone in the faculty. With the provision of this free water dispenser, the faculty encourages everyone to start bringing their own drinking bottles. Furthermore, the faculty also stopped providing bottled drinking water for lecturers. Instead, lecturers are provided with a glass of water which will be washed and refilled before the class starts.
The Faculty of Public Health also issued SE-744-UN2.F10.D-HKP.04-2020 – Appeal for Limiting the Use of Plastic and Paper as an updated circular and reminder for the community.
