Generally, Central Java Province is quite prone to drought. Based on the balance sheet need’s water in 2020,Java will have a fairly large deficit in water demand. This study aims to overcome its conditions appropriatetechnology-based countermeasures. The method that used in this research is a literature review, secondarydata collection, field observations and round table discussion. The result of this study is an analysis ofconstruction that solving deficit water conditions in districts of Karangmoncol , Purbalingga regency. Theconcept of construction proposed is implementation efforts are made especially for treatment with thetechnology of production ponds, ABSAH (Artificial Aquifer of rain water Deposit, Akuifer Buatan SimpananAir Hujan ) model . Karangmoncol District have problems in the availability of raw water, because well isvery deep in the dry season. As an alternative can be taken the second highest value of ABSAH. In Indonesian,the schemes attributed to the so called ABSAH (Akuifer Buatan dan Simpanan Air Hujan), which stands forArtificial Aquifer and Rainfall Storage (AARS). AARS is a result of modification of the well known rainfallharvesting storage tank (PAH) schemes. A guideline for designing this AARS has been accepted for solvingwater shortage problems elsewhere in Indonesia. This paper discusses the concepts and philosophy ofdesign and modification view points behind these new schemes. Based on population data 2350 person in535 household we taken 5 person every household. Everyday water demand calculated ais 125liter/man/day , so we should provide 625 liter/day every household. We have taken rainfall data inKarangmoncong district and it required 70 m2 roof area of the house for providing everyday needed byevery household. By the calculation of the dimensions as needed every day obtained the valid dimensionis 12m in length , 5m in width and 2.5m in depth.Keyword : Karangmoncol, Rainfall, population data, roof area, absah, harvesting rainfall storage
