The geomorphological condition of Fakfak Regency is dominated by limestone. It makes ground water difficult to access. The clean water crisis in Fakfak Regency requires people to look for alternative sources of clean water such as rainwater. However, during the dry season, people will have great difficulty with clean water. Cloudfisher or fog catcher is a technique for collecting fog that have condensed into water. Cloudfisher's ability to catch fog or dew and produce water varies depending on the situation with an average of around 2 liters – 10 liters/m2/day. The ability of this technology to produce water depends on the net material used, the size of the net, the direction and model of the net, and the location of the net placement. In this research, the potential cloudfisher to produce water in Fakfak Regency will be examined, with the ultimate aim of seeing how effectively this technology is applied in Fakfak Regency in terms of the amount of water produced. The method used in this research is a field study by reviewing locations in Fakfak Regency with the altitude, fog conditions, temperature and humidity that are most suitable for the application of cloudfisher technology. The fog catcher was installed using a standard research model using 65% and 85% cover nets. Each fog catcher material was installed for 1 month and the amount of water captured by the tool was checked every morning at 06.30 am. The location of the fog catcher is based on several factors including altitude, air humidity, fog frequency, temperature and wind speed. The average water volume obtained in the 65% cover net was 59.6 ml while in the 85% cover net it was 26.24 ml. Factors that influence the amount of water obtained are net material, net cover, fishing area, equipment placement, and weather. The fog catcher (cloudfisher) in Fakfak Regency has the potential to be used but still requires further research regarding the design and materials used so that more water can be obtained and can be used by local communities as an alternative source of clean water

Water loss can be defined as the difference between the recorded amount of water in the system and the amount of water out of the system shown, in a water supply system is not entirely produced water installations reach consumer. Usually there is a leak here and there, called the loss of water. Then to reduce or minimize the water loss rate needed the right solution. One of solution that can be used is the Non Revenued Water (NRW) program. NRW can be defined as water that can be measured and a known amount of be chased but can not or may not be income, but it can be justified. The one of the methodologies that can be used to determine the amount (NRW) is a method of infrastructure leakage index (ILI) used Software WBEasycalc3. Water loss rate is the percentage ratio between water loss and the amount of water distributed in piped water network, while the water balance is calculated based on the amount of incoming water flow, consumption meter-Revenue, customer meter inaccuracies, water loss and physical loss. Both of two magnitudes in the ILI value is calculated by using Table Matrix Target that compiled by regulators of water service DKI Jakarta.
