Abstract

The main objective of this research is to assess the harvesting capacity of the deep rainwater harvesting wells as one of the solutions to prevent the ground water crisis. Water is life, for present and future generations. Groundwater is a renewable natural resource; however, over exploitation can cause various disasters, it leads to the decreasing of water table, seawater intrusion and worse can cause land subsidence. This phenomenon has allegedly occurred in Bali, a beautiful small island with an area of 5,780 km2 and a population of 4.22 million. The 3–5 stars hotels increased significantly from 120 hotels in 2010 to 498 hotels in 2022. The international community claims that this hotel growth, which considered to be less controlled, will lead Bali to face the water crisis in Bali soon. The research conducted in 2010 showed that in 11 tourism areas there was a decrease in the level of ground water and the occurrence of seawater intrusion, which reduced the quality of ground water. Based on this data, the research re-conducted in the 11 tourism areas and in several other developing tourism areas. The result shows that the water quality from the chlorine content and hardness, does not meet the recommended quality standards. This shows that the area has experienced seawater intrusion. One of the alternative solutions to avoid the groundwater crisis is by saving the water through the rainwater harvesting wells. Deep rainwater harvesting wells was designed and implemented in some recharge area and the assessment showed that it can harvest the rainwater 41.087 m3/jam/wells during the wet season.

Bali has 4 wet months or around 120 rainy days per year. If each star hotel builds at least 1 well to compensate for the production well used for hotel operations, then the rainwater harvested is about 58,928,618.88 m3 per year.
