SDG 6 – Indicator 6.3.1 – Wastewater treatment
Wastewater Recycling as a Step to Overcome Water Scarcity
The wastewater treatment process is an effort to manage wastewater to remove contamination in accordance with certain standards so that the wastewater is safe and can be reused. Wastewater that is treated or recycled is greywater wastewater. This type of wastewater is non-caustic wastewater. The treatment process will reduce the negative impact produced by the waste. Universitas Sriwijaya (UNSRI) implements a wastewater treatment process before it is reused or flowed through a prepared channel. The wastewater treatment process uses a filtration process. After the treatment process, the water can be utilised for other purposes, such as watering plants and toilets.
SDG 6 – Indicator 6.3.2 – Preventing water system pollution
Water Tanks to Prevent Pollution of Water Sources
Water is one of the main needs for survival. Preventing water from being polluted is the responsibility of all parties including educational institutions. Universitas Sriwijaya (UNSRI) is one of the educational institutions in South Sumatra that has built several water tanks used in the campus environment. This is done to prevent contamination or pollution of water sources. The water tanks are made of concrete, some of which are built on the ground. Proper channels are also built around the tanks to prevent liquid waste from flowing into the tanks. In addition to building water reservoirs, UNSRI also provides storage using commercial water tanks to prevent pollution of the water. The tanks are periodically checked to ensure that they are still functioning properly. The water quality testing process is also carried out periodically.

SDG 6 – Indicator 6.3.3 – Free drinking water provided
Free Drinking Water Access in Universitas Sriwijaya
Water is the main human need for survival and is used in daily life, for example as drinking water. To fulfill the need for drinking water on campus, Universitas Sriwijaya (UNSRI) provides free access to drinking water for teaching and education staff. The provision of drinking water is budgeted through each work unit within UNSRI. The free drinking water can also be accessed by students or guests of UNSRI who need it. The drinking water provided has met the drinking water standards set by the government.

SDG 6 – Indicator 6.3.4 – Water-conscious building standards
Water Saving through Building Construction that Minimises Water Use
Water is indispensable for humans in their daily lives. To fulfill the need for water, it is necessary to have a water source that meets the quality requirements. Excessive water use will certainly disturb the balance between water supply in a particular environment. Several things have been done to minimise the use of water, for example by increasing individual awareness of water and the construction of buildings that can minimise the use of water. In support of this, Universitas Sriwijaya (UNSRI) has installed several hand-washing taps and flush toilets in buildings on the UNSRI campus. UNSRI has also implemented water-conscious building structures through rainwater harvesting in several main campus buildings. The water can then be directly used for plant needs.
SDG 6 – Indicator 6.3.5 – Water-conscious planting
Drought-tolerant Plants as a Way to Keeping the Campus Green
Water is the main source of life, including plants. In supporting the growth and development of plants, adequate water is needed for the plants. Some plants require a lot of water, but there are also plants that are tolerant of little water or require little water (drought-tolerant plants). Some of these plants have been planted at Sriwijaya University (UNSRI), for example Philodendron selloum is one of the plants classified as drought tolerant. Sansevieria pearsonii and Hippeastrum papilio are also drought-tolerant plants.
