Measuring Water Use Across the University Campus

Universitas Islam Sultan Agung (UNISSULA) monitors the volume of water used across the university campus as part of its commitment to sustainable water management and responsible use of natural resources.

In 2025, UNISSULA recorded a total annual water consumption of 90,491 m³. The university’s water supply is primarily sourced from groundwater extracted through wells and aquifers and from the campus lake.

The university also maintains water treatment, storage, and distribution infrastructure to support the daily needs of students, lecturers, staff, and other campus users. The available documentation identifies this evidence under Consumption of treated water and includes visual documentation of water-related facilities and the campus lake.

Water Sources

UNISSULA uses local water sources to support academic, administrative, and other campus activities.

The main water sources used by the university are:

• groundwater extracted through wells and aquifers;
• water from the campus lake.

The supporting document states that UNISSULA uses water extracted from sources including lakes and aquifers, which is then treated and distributed for campus use.

The use of these extracted water sources makes regular monitoring important for maintaining responsible and sustainable water management.

Total Water Consumption in 2025

UNISSULA measures the total volume of water used throughout the university.

For the 2025 reporting period, the recorded water-consumption data were:

The figure of 90,491 m³ represents the total volume of water measured for university use during 2025.

University-Wide Water Monitoring

Water-consumption monitoring covers the university campus and is used to understand overall water demand across institutional operations.

The monitoring includes water used in areas such as:

• academic buildings;
• administrative facilities;
• supporting campus facilities;
• sanitation facilities;
• worship facilities;
• student activity areas; and
• other operational areas of the university.

This university-wide approach provides UNISSULA with a clear picture of its annual water use and supports more effective planning for conservation and efficiency.

Water Treatment and Distribution

Water from available sources is managed through campus water infrastructure before being distributed for use.

The university has facilities that support water treatment, storage, and distribution. The supporting documentation shows water-related infrastructure, including storage facilities and the campus lake.

This infrastructure supports the daily water requirements of the university community while helping UNISSULA manage water resources in a more organised and sustainable manner.

Supporting Responsible Water Use

Monitoring total annual water consumption provides an important baseline for sustainable campus management.

By recording water use, UNISSULA is able to:

• understand annual water demand;
• monitor changes in water consumption;
• identify opportunities for water-efficiency improvements;
• support conservation planning;
• manage water infrastructure more effectively; and
• promote responsible use of water resources.

The annual monitoring process therefore supports both operational management and long-term sustainability planning.

Sustainable Management of Groundwater and Lake Water

Because UNISSULA uses groundwater and lake water, monitoring consumption is particularly important.

Groundwater extracted from wells and aquifers is a valuable natural resource, while lake water is part of the university’s local water environment. Responsible use of these sources requires the university to understand how much water is being consumed and to manage extraction and distribution carefully.

The measurement of 90,491 m³ in 2025 provides a quantitative basis for evaluating water use and improving future water-management practices.

Supporting Campus Operations

Water is used across many areas of university life, including:

• teaching and learning activities;
• laboratories;
• sanitation;
• administration;
• religious activities;
• student facilities;
• maintenance; and
• other daily campus operations.

By measuring total water consumption, UNISSULA can manage these needs while also maintaining attention to sustainability and resource efficiency.

2025 Water Consumption Summary

UNISSULA’s water-consumption monitoring for 2025 can be summarised as follows:

• Water sources: groundwater from wells/aquifers and campus lake;
• Total annual water consumption: 90,491 m³;
• Reporting period: January–December 2025;
• Coverage: university-wide;
• Measurement purpose: operational management, resource efficiency, and sustainable water use.

Commitment to Sustainable Water Management

UNISSULA recognises that responsible water management is an important part of building a sustainable university campus.

By monitoring the volume of water used each year, the university strengthens its ability to make informed decisions about water conservation, infrastructure, efficiency, and future resource needs.

The university’s water-consumption data also provide an important foundation for evaluating water use in relation to the size of the campus population.
