Geographic information system (Sig) water distribution Pdam Tirta Daroy Banda Aceh using ArcGIS 10.3 and evaluation of distribution network system

Clean water demands in the community that is increasingly rising must be followed by the availability of adequate water. Supply of clean water in the settlements must be provided with the quality that meets the health standards, sufficient quantities, sustainable as well as easy to get and affordable. Efforts in improving the water service especially to customers of PDAM Tirta Daroy in Kutaran and Podiamat, Alue Naga Village Banda Aceh is related with supply and demand method. The research method performed by evaluating the distribution system (supply) and the customers (demand) of the clean water. This research is in the form of data processing of a survey that conducted by adopting ArcGIS 10.3 and Epanet 2.0 software. The purpose of this research is to create a database of distribution network and customer geographically based, evaluation of distribution system and also to analyze the capacity of the distribution towards the distribution of clean water to customers. The results of the study are creation of distribution network and customers of clean water geographically database by adopting software ArcGIS10.3. The evaluation of distribution network installed toward the amount of water demand is evaluated by using software Epanet 2.0. Objects used in this research is 152 junction, 1 reservoir, 173 pipes, and one pump rated flow at the pump curve by 1.64 litre per second tailored to the needs of customers in Kutaran and Podiamat of 1,453 litre/person/second for needs an average of 150 people per litre per day. Pressure on the simulation relatively stable with the smallest value of 2,840 bar, but the level of water supply to customers less than 50% of the amount of water needed by the customer. The flow value of the pipes 150 with a speed of 0.2965 litre per second. On pipes 308 and 206 pipes there is no flow of water because there is no demand at the junction and the upstream end.
