<![CDATA[Abstract Water is an essential and vital resource for all living organisms; without it, life on Earth would be unsustainable. Although the Earth has abundant water, the available supply of clean water is insufficient to meet demand, causing many people to suffer from water scarcity. Water shortages can be triggered by rising demand due to population growth, uneven water distribution, increasing water pollution, and inefficient water use. The misuse of water, especially in large cities, is alarming, as water exploitation can reduce water sources and disrupt water sustainability. Groundwater has various benefits, particularly as a primary source of clean water for communities, compared to surface water sources. Additionally, groundwater supports environmental stability by preventing land subsidence, sea water intrusion, and worsening groundwater pollution. To anticipate water shortages, alongside wise and controlled water usage, rainwater harvesting can be employed as an alternative water source. One method of water conservation in every household is rainwater harvesting, which involves collecting, storing, and conserving rainwater. Rainwater harvesting has been practiced for centuries in various countries experiencing water shortages. Harvested rainwater can be used for multiple purposes, such as watering plants, washing, bathing, and even cooking if the water quality meets health standards. The creation of biopores is another alternative in groundwater conservation, as this method returns surface water back into the ground. Given the above points, a team of lecturers and students from the Civil Engineering Study Program is attempting to provide training to the Kramatjati community on how to independently conserve water in each household.
