[4.1] Water Conservation Program Implementation
Description:
Halu Oleo University has widely implemented measures to conserve water resources across campus land. The water conservation measures primarily consist of wetlands both natural and artificial, porous pavements, biopore installation, and vegetated. Original Natural wetland as a reservoir and protection place for water that is formed naturally due to low elevation factors. Natural wetlands are generally covered with endemic aquatic plants and aquatics. Artificial wetlands, which are also water reservoirs that were deliberately created by the campus to accommodate excess water during the rainy season as retention and detention ponds. Porous pavement is a pavement that has voids so that it can absorb water to the ground and then replenish groundwater. At Halu Oleo University, porous pavement is largely implemented in road pavement and parking areas. The Biopores are artificial holes with a diameter of 3″ and a depth of 40 cm each. The total number of biopore holes is around 215 holes, spread throughout the campus area. This type of water conservation is placed in flat land. Vegetated swales are a place for accelerating the process of water infiltration into the ground to anticipate inundation or flood disasters. This is also home to various plants and aquatic creatures. These water conservation programs have been implemented in all faculties and its surrounding environments at Halu Oleo University
[4.2] Water Recycling Program Implementation
Description:
Haluoleo University has implemented a water recycling program by utilizing almost all water from air conditioners and rain harvesting for reuse. Air conditioning is collected in a container and used to water plants around the building and cooling car machine. By doing this, it significantly reduces the use of clean water. Rainwater from the roof of the building is also collected in the water tower and then flows into the toilet, which is used for flushing the toilet and sink, and flows into the handwashing taps located around the building. In addition, rainwater harvesting is largely used for watering flowers and ornamental plants. Rainwater that enters the canal is put into a water tank embedded in the ground and reused. Collecting rainwater from roofs and drainage channels can reduce the use of clean water during the rainy season. These programs have been fully implemented in all faculties at Halu Oleo University
[4.3] Water Efficient Appliances Usage (e.g. hand washing taps, toilet flush, etc.)
Description:
In terms of water efficient appliances, all campus buildings in Halu Oleo University have been installed with a wide range of water-efficient appliance types both inside and outside of the buildings. For Inside building, It applies water efficient appliances such as flushing or censored urinoirs, flushing toilets and censored hand washing taps. For outside buildings, it primarily includes a landscape watering system, such as sprinkler water distribution system. The main objective is to save water. All of this technology has been implemented in all faculties at Halu Oleo University.
[4.4] Consumption of treated water
Description:
Halu Oleo University has implemented a range of measures to treat water for consumption or use. All treated water has been mainly used for drinking water, flushing toilets, watering landscape plants, washing cars and fire hydrants. For these reasons, water treatment methods have been applied and installed based on water source quality and use. For example, for drinking water purposes, cleaner water sources are thoroughly treated using commercial filters to meet drinking water standards. The lower treated water quality is used for flushing toilets and watering vegetation. These treated water consumption programs have been undergone in all campus building at Halu Oleo University. In the future, volume and quality of treated water will be increased.
[4.5] Water pollution control in campus area
Description:
Since 2016, Halu Oleo University has a strong commitment to control water pollution within campus areas by launching green campus policy through Rector degree No. 1630b/UN29/SK/KP/2016. Under this policy, a green task force has been formed to manage water pollution issues at the campus. One of the task force activities is that each year the task force holds green metric assessments for each campus building and surrounding areas. In terms of water pollution control, the assessment includes monitoring the water quality from water bodies that are closely connected with wastewater outlet from campus buildings. In addition, cleaner water sources for drinking water purposes are regularly sampled to control water pollution to this source. This is by taking water samples and testing some parameters at Laboratory.
