The Water Recycling Unit (WRU) is an innovative wastewater treatment technology specifically designed to recycle domestic wastewater from toilets into reusable water, suitable for purposes like toilet flushing. This technology provides a practical solution to reduce groundwater or municipal water (PDAM) consumption, especially in areas with limited access to clean water. Implementing WRU has proven to reduce daily clean water usage by 30-40%, optimizing water resource utilization efficiently. By adopting WRU, not only can water consumption be significantly reduced, but it also fosters a more sustainable future that is responsive to the global clean water crisis.
Pilot Project 1
Launched in January 2025 at SMKN 66 East Jakarta in collaboration with ASTRA, this initiative installed a Water Recycling Unit (WRU) with a capacity of 1,000 liters, serving the 100–200 students who use the school’s toilets daily. Currently, the recycled water is used for watering plants, with plans to extend its usage to toilet flushing. This initiative not only educates students on the importance of sustainable wastewater management but also demonstrates WRU’s capability to reduce reliance on groundwater or municipal water (PDAM) by 30-40% daily, aligning with the school’s Adiwiyata (environmentally conscious school) goals.
Pilot Project 2
Implemented at the Military Dormitory of Yonif Raider 400, Semarang, in June 2023, this project also used a WRU with a capacity of 1,000 liters, serving approximately 70 dormitory residents. Currently, the recycled water is utilized for toilet flushing. This application in a military community setting showcases the effectiveness of WRU in reducing clean water consumption while supporting sustainability principles.
