We prioritize responsibility for the environment by implementing efficient wastewater treatment processes that ensure UNIMAS water discharge meets high environmental standards. One of the approach is for research to be translated into practices. Among the efforts that have been done in UNIMAS are :

We take proactive measures in preventing polluted water from entering the water system, addressing incidents or accidents that may occur within UNIMAS's premises. Among the efforts that have been done were :

Application Of Transport Equation For Determination Of Water Pollution

Water pollution is a significant environmental issue that affects the quality of water resources and has negative impacts on human health and ecosystems. The transport of pollutants in water bodies is governed by the advection-diffusion equation (ADE), which describes the movement of a substance in a fluid due to the combined effects of advection (i.e., movement with the fluid) and diffusion (i.e., spreading due to random motion of the fluid particles). In this research, we will investigate the concentration of pollutant transport in a water body using one dimensional advection-diffusion equation (1-D ADE). We will use explicit forward time central space (FTCS) scheme as the numerical method for solving the equation. The results of this research will provide insight into the transport of pollutant in a water body that may contribute to the development of effective management strategies to mitigate water pollution.

To promote hydration and well-being, UNIMAS provides free drinking through conveniently located water dispenser for students, staff, and visitors around the campus.

BUILDING STANDARD MINIMIZE WATER USE UNIMAS Rain Water Collector in CUBE (Academic Block)

Rainwater from the roof enters the gutter downpipes through the filter’s inlet and flushed down through the drain pipe. Clean filtered rainwater then channeled to first flush diverter of the storage tank.


 

FREE DRINKING WATER

UNIMAS has provided safe drinking water to their students by providing water dispenser in every each block in Faculty and Residence College. The Water Cooler is connected to the water mains, guaranteeing constant quality over time and requiring extremely limited maintenance, providing a reliable drinking water system. 

Direct connection to the water mains maximizes hygiene and prevents water from stagnating. Inclusion of glass filler faucets for cold and cold water gives one the versatility to either drink directly from the fountain or fill a water bottle.

UNIMAS has created a project towards minimizing water use in new buildings in the Academic Block, Central UNIMAS Building for Educators (The CUBE) by using rainwater collector for the daily use. 

Rainwater from the roof enters the gutter downpipes through the filter’s inlet and flushed down through the drain pipe. Clean filtered rainwater then channeled to first flush diverter of the storage tank.

Through the use of low maintenance plants and strategically planted plants , UNIMAS strive to create beautiful and eco-friendly outdoor spaces that not only conserve water but also contribute to a more resilient and sustainable campus environment.

In programs such as tree-planting events, indigenous tree species are chosen because native plants have adapted to the soil and climate conditions, requiring less watering. Among the tree-planting events that have chosen indigenous species to be planted in UNIMAS is Tagasako-Unimas Educational Forest .

Understanding the importance of having a comprehensive policy in place to maximize water reuse across the campus, reducing water wastage and promoting sustainability; UNIMAS has put in place the need to establish a water reuse policy in Initiatives and Directions for SDG 6 in the UNIMAS Sustainability 2021 -2025 Masterplan.

Among other water policies that are adopted and use in UNIMAS are 

Technical Standard For Use Of Reclaimed Water

Dasar Sumber Air Negara

 

Plant Landscape Minimize Water Use

Landscape at the university led to the planting of trees or plants that do not require the use of water and care. Mimusops elengi as the dominant species planted and they complied with the urban forest health status guideline, whereby a diverse tree population might slow or prevent the spread of insects or diseases, and in the event that such pests should become established, the impact on a diverse tree population may be less severe In Borneo there is a lot of rainfall and this also helps to revive existing crop.

Wastewater Treatment in UNIMAS

The purpose of the Neutralization Plant in Faculty of Engineering and Faculty of Resource Science & Technology, UNIMAS is to treat the wastewater generated from the laboratory to the acceptable pH range as specified by Department of Environment Malaysia. Design condition as follows:

Total maximum incoming flowrate : 200 m³/day || Design flowrate : 20 m³/hr || Influent Time of Incoming Wastewater : 10 hours/day || Peak flow : 40 m³/hr || Influent pH : pH 4.0 TO 10.0 || Discharge pH requirement : pH 5.5 to 9.0.

Wastewater produced from the laboratory flows by gravity to the Neutralization Plant. Intially, the wastewater will enter the Raw Waste Water Tank which act as a pump station for temporary storage. Depending on the tank’s water level, Raw Waste Pump will pump the wastewater to the Equalization Tank. Coarse bubble diffuser are installed at the bottom of the Equalization Tank to provide well-mixing effect in order to achieve homogeneous wastewater. The homogeneous wastewater is then transferred by pump to the Neutralization Tank for neutralization process. Sodium Hydroxide (NaOH) and Hydrochloride Acid (HCL) are used to adjust the pH to an acceptable range of pH 5.5 to pH 9.0. The treated wastewater is then ready to be discharged.

In conjunction with World Water Day 2024, UNIMAS Water Centre organized the “Leveraging Water for Peace” Creative Video Competition to inspire awareness and advocacy for water conservation beyond campus.

The competition encouraged participants to produce a 3-minute video highlighting the importance of water in promoting peace and sustainability. By engaging students and the wider community, the initiative fostered creativity and strengthened understanding of responsible water management and conservation practices. Winners were announced on 22 April 2024, marking a successful effort to extend UNIMAS’s outreach in promoting sustainable water use.
