"Water is life… the need and utilization of ground water is increasing, while the need to recharge water into the soil is being underestimated,” said Dr. Lilik Sudiajeng, PNB Professor of Civil Engineering and head of research. High demands for fresh water from Bali’s densely populated urban and tourism areas, has seen water supplies diverted from vital agricultural areas to tourist precincts in the south that now threatens the island’s future food security, UNESCO designate…
Project ResultsThe main function of this absorption wells is as a place collect rainwater and absorb it into the soil. Some Functions of absorption wells, among others: 1) Flood controllers, many surface streams that can be reduced through absorption wells depend on volume and number of absorbing wells. 2) Groundwater conservation, water infiltration through absorption wells is very important given the changes in land use on the surface of the earth as a consequence of the development of the population and the economy of the community. Changes in land use will reduce the ability of the soil to absorb water. It is remembering the more soil covered by walls, concrete, asphalt, and other buildings that would have an impact on the increase in surface flow rate. Closure of the soil surface by settlements and public facilities of large impacts of its parts, meaning that every 30 mm rainfall there will be 225,000 m3 of rainwater that can not seep into soil. This amount will congregate with surface flows from other areas on low land which may result in flooding. 3) Suppressing the rate of erosion, with a decrease in the flow of the surface then the rate of erosion will decrease. If the surface flow decreases, the eroded and drifted soil will decrease. As a result, small rainwater surface flows and erosion will be small. In the plan of making absorption wells need to be considered climate factors, groundwater conditions, soil conditions, land use, and socio-economic conditions of the community. Climate factor to consider is the amount of rainfall, the greater the rainfall in a region means the greater absorption wells needed. The deep groundwater conditions, the absorption wells need to be made massively because the soil really needs the water supply through the absorption well. Meanwhile, the benefits that can be obtained from making water absorption wells include: 1. reduce surface flow and prevent puddles, thus minimizing the possibility of flooding and erosion, 2. Can increase the groundwater potential because in addition to accommodate and drain, can also absorb some rain water into the soil, so it can help maintain water balance and save water resources for the long term. 3. Can help reduce puddle inundation and widespread sea water intrusion into the land. 4. preventing land subsidence from causing excessive groundwater removal, and reducing the concentration of groundwater contamination. 5. Making absorption wells can also attract labor and labor-intensive projects through community empowerment programs, for example 6. How to manufacture absorption wells does not require high technology 7. With the regulation of water flow, it is expected that groundwater contamination can be kept as low as possible.
