In Purwakarta Regency there is a new area designated as a residential, commercial and industrial area, namely the Jatiluhur Estate Area. With the new area, it is necessary to know whether the availability of water can meet its water needs (water reliability) for the next 50 years. This research also carried out the water reliability mapping. Based on the analysis, both water availability with dependable discharge Q80% and Q90% overall and monthly, can fulfil the water needs of Jatiluhur Estate until 2070. However, with the regulation of water intake in the river, a ground tank is needed which takes into account the water loss of 19%, so that Q90% dependable discharge can fulfil the need while carrying out the regulation. From the results of monthly water reliability mapping, water reliability with Q80% and Q90% (overall) generate one color, four colors with Q80% (monthly), and three colors with Q90% (monthly). Whilst, the annual water reliability map generates one color for water reliability with Q80% and Q90% both overall and monthly.
