Raw service system Mranggen Unit is divided into areas service (service area Mranggen, Batursari I, Batursari II, Batursari III and Kebon) which utilize raw source treatment plant (IPA Waru) and 8 Wells In a total discharge 0 liter/second. The number home connections in Pucang Gading area is currently,7 house connections, with a total usage. liter/second Water discharges from clean sources in Pucang Gading region are currently not maximally available to supply to Pucang Gading service area. In this research will know the problems and readiness that exist by looking from the achievement Medium Term Development Plan Demak Regency Year 0-0. This research uses SWOT analysis method that is internal and external factors. The selection raw sources for drinking should pay attention to aspects quality, quantity and continuity. Demak Regency has the potential surface either river/ reservoir/dam. The problems and challenges drinking supply include issues safe access to supply, and regulation ground utilization for the community. Keywords : raw supply, SWOT analysis, government policy, resources management. Introduction Mranggen Sub-district is one the sub-districts in Demak District. In the north it is adjacent to Sayung Subdistrict, Regency Karangawen in the east, Regency Semarang in the south and Regency Semarang in the west. The farthest distance from west to east is km long and from north to south along 9 km. Distance to the Capital Demak 9 km, while the distance to the district around is to District Karangawen 7 km and to District Sayung km. The condition clean production in drinking supply in Pucang Gading area Mranggen district Demak Regency is 77.%. This shows that in Pucang Gading service, the loss rate is quite high, because it exceeds the maximum allowable loss rate 0% (General Cipta Karya Dinas PU). While the level loss in the distribution pipe is 0.7%. he current condition drinking supply in Indonesia is that access to safe drinking is only 7.7% consisting 7.9% pipeline network instead 9.8% pipeline network. For the drinking service Provincial Government Central Java for urban areas amounted to 7.8% while for rural areas reached.7%. Referring to the policy drinking provision in Indonesia with the goal meeting the needs drinking adequately that meet health requirements, the targets mandated in the National Medium-Term Development Plan 0-09 namely the achievement 00% secure access to drinking in 09, consisting from drinking service through piped network (JP) 0% or 7.7 Million house connections, and through non-piped network (BJP) protected by 0% or.9 Million Household. In order to achieve 00% safe and sustainable drinking access target in 09, the Directorate Development Drinking Water Supply System proclaimed the 0 million house connections program which is the target adding % per year pipeline access network or million house connections per year, with the total addition house connections to with 09 0 million house connections.
