Universitas Airlangga Implements Measureable Water Reuse for Sustainable Campus Operations

Admin SDGS — Wed, 22 Nov 2023 01:05:35 +0000

Universitas Airlangga is taking groundbreaking steps in sustainable campus management through its meticulously measured water reuse program. Guided by formalized policy, including Rector's Decree No. 1837/UN3/2018 on Water Recycling and Water Harvesting, UNAIR has implemented a comprehensive approach to track and maximize water reuse, a commitment that is transforming environmental responsibility within higher education.

Throughout the year, UNAIR reused 150,259 cubic meters of water, equivalent to tens of thousands of swimming pools. This reclaimed water— sourced from rainwater harvesting and treated wastewater from campus facilities such as mosques and sewage treatment plants—serves non-potable needs, including irrigation, toilet flushing, and cooling systems. The systematic tracking of water usage not only reduces overall consumption but also curbs reliance on external water sources, cutting costs, and underscoring UNAIR's commitment to sustainable resource management. The reuse policy is practical model of resource conservation that aligns with Sustainable Development Goal 6 (Clean Water and Sanitation).

Harnessing Technology for Efficiency

Advanced technologies play a central role in UNAIR's water management strategy. In campus landscapes, automatic control panels monitor and regulate irrigation, delivering water only when needed. These systems significantly improve irrigation efficiency allowing for precision in water usage, a solution particularly crucial for drought-prone seasons. The automatic control panels are located at eight strategic points throughout the UNAIR campus.

Educational Outreach and Research Integration

Beyond operational gains, UNAIR's commitment to sustainable water use has opened doors for educational opportunities, integrating environmental awareness into academic and community outreach programs. Workshops, seminars, and practical demonstrations on water reuse serve to educate the campus and surrounding communities, fostering a culture of sustainability. The policy also encourages student involvement in water conservation projects, making UNAIR a model of how educational institutions can bridge research and practical application to promote environmental stewardship.

In combining policy, technology, and educational outreach, UNAIR's water management initiatives underscore its mission to create a green, more sustainable campus. By optimizing water use and reducing environmental impact, Universitas Airlangga is setting a benchmark for universities worldwide

Universitas Airlangga Implements Water Reuse Policy to Support Sustainable Campus Managemet

Admin SDGS — Wed, 07 Jun 2023 07:20:07 +0000

Universitas Airlangga (UNAIR) has established a robust policy framework to maximize water reuse across its campuses, reinforcing its dedication to environmental sustainability and resource conservation. This initiative is formalized under Rector Decree No. 1837/UN3/2018 on Water Recycling and Water Harvesting, along with Rector's Decree No.2094/UN3/2016 on Green Campus Management. These decrees collectively outline UNAIR's commitment to responsible water management and reuse, reuse supporting its role as a sustainable university leader.

Structured Water Reuse and Conservation Policies

Water Recycling Program

To optimize clean water use, UNAIR's policy mandates the recycling of treated water across campus for various purposes, including irrigation and sanitation. These water recycling initiatives utilize advanced filtration systems to treat wastewater, ensuring it meets safety standards before reuse. The wastewater treatment installations help maintain water quality while reducing the environmental impact of wastewater discharge.

Rainwater Harvesting System

UNAIR has equipped campus buildings with rainwater harvesting sytems to capture and store rainwater for non-potable uses, such as landscape irrigation and toilet flushing. This system reduces the university's reliance on municipal water supplies, promoting a sustainable alternative that makes efficient use of natural rainfal. According to Rector's Decree No.1837/UN3/2018, the harvester rainwater is directer to irrigation networks across campus greeen spaces, supporting the university's efforts to conserve water resources.

Water Conservation and Efficiency Standards

In addition to recycling and rainwater harvesting, the policy emphasizes the reduction of deep well usage and the implementation of efficient water distribution systems. Policy Number 2706/2022 about waste water management outlines guidelines for the installation of efficient faucets and fixtures that minimize water use. Sensor-activated faucets are deployed in many campus facilities to reduce unnecessary water flow, helping UNAIR

These policies align closely with Sustainable Development Goals 6 - Clean Water and Sanitation—promoting resource conservation and sustainable campus operations. By reusing water and prioritizing conservation, UNAIR reduces its environmental impact and contributes to water sustainability on a regional scale. The integration of these policies into everyday campus operations demonstrates UNAIR's proactive approach to sustainable water management.
