Telkom University Strengthens Its Water Conservation System to Support Sustainable Campus Development

Keywords: WaterConservation, Sustainability, SmartTechnology

Water Conservation Infrastructure

Telkom University already operates a well-structured water conservation infrastructure. Every building at Telkom University has been equipped with infiltration wells, allowing rainwater from rooftops and surrounding areas to seep naturally into the ground rather than flowing directly into final reservoirs or lakes. This mechanism helps replenish groundwater reserves and prevent surface flooding, strengthening the campus’s ecological resilience.

Meanwhile, the sewerage system channels wastewater into a dedicated reservoir with a capacity of 15 cubic meters, which functions as a filtering basin to treat used water before it is released to the final reservoir or lake. This treatment process ensures that only filtered and environmentally safe water reaches the main water body. This eco-friendly infrastructure forms an integral part of Telkom University’s green building design, ensuring that every structure contributes to water conservation and environmental preservation.

Water Reuse and Efficiency Optimization

The main campus lake serves as a central component of Telkom University’s water reuse system. Treated water stored in this lake is reused for irrigating green areas, watering vegetation, and supporting non-consumptive activities across the campus. According to the university’s water management data, approximately 656 cubic meters of water are reused daily, closely aligning with the university’s average daily water consumption. Through this reuse mechanism, Telkom University successfully reduces its dependence on external clean water sources and minimizes its environmental footprint. This initiative exemplifies how the university combines innovation and environmental responsibility to ensure long-term sustainability and resource efficiency.

Water Reuse Measurement

Telkom University also implements quantitative water reuse measurement as part of its smart environmental management program. By regularly assessing the volume of recycled and reused water, the university can continuously evaluate the effectiveness and performance of its conservation systems. This data-driven approach enables evidence-based decision-making, encourages continuous improvement, and ensures compliance with sustainability standards and internal green metrics.

Prepaid Smart Water Meter: A Digital Innovation with LINFLOW

In alignment with its vision for sustainable and intelligent campus management, Telkom University—through Dr. Hanif Fahruroza from the Faculty of Industrial Engineering—has collaborated with LINFLOW Water Supply Equipment to develop the Prepaid Smart Water Meter System. This innovative system integrates smart meter devices, the L-Connect App, and a web-based dashboard to provide real-time water usage tracking, digital payment options, and transparent monitoring of clean water distribution.

The prototype, tested under real environmental conditions, connects multiple smart meters in series to simulate accurate flow measurement, data transmission, and prepaid functionality. This technology addresses Indonesia’s ongoing Non-Revenue Water (NRW) challenges caused by illegal usage, inaccurate readings, and inefficient billing. Through token-based prepaid payments and digital integration with virtual accounts, the system allows users to monitor their consumption directly while enabling PDAMs (local water utilities) to manage billing remotely—reducing operational losses and improving efficiency.

Key Features:

• Token-based prepaid water system
• Real-time usage tracking via the L-Connect App
• Web dashboard for PDAM management and analytics
• Android application for users and field officers
• Integration with digital payment gateways

Real-time consumption and leak monitoring sensors

The Prepaid Smart Water Meter System has undergone pilot testing at PDAM Subang and several modern residential areas. It is currently at Technology Readiness Level (TRL) 5, indicating validation of components and integrated systems in a relevant environment. Copyright protection and industrial licensing partnerships are also in progress to support broader implementation and commercialization.

Commitment and Global Recognition

Through its integrated conservation infrastructure, water reuse innovation, and smart monitoring technologies, Telkom University demonstrates leadership in Water Conservation and Sustainable Campus Development.

The university’s initiatives not only reflect its scientific and technological advancement but also its active participation in global sustainability platforms, such as the UI GreenMetric World University Rankings, which recognize institutions committed to green innovation and environmental stewardship.

Conclusion

By combining accurate water reuse measurement, smart metering innovation, and eco-friendly infrastructure, Telkom University ensures that every drop of water is managed responsibly, efficiently, and transparently. These initiatives reaffirm the university’s vision of becoming a smart, sustainable, and globally competitive campus, where innovation, environmental awareness, and community engagement unite to build a greener and more resilient future.
