Clean water in human life has a very important function. The trend that is happening now is reduced availability of natural water resources that can be used directly from day to day. This is due to influence of increasing development progress, population growth increase so that the capture of water by the soil as a source of ground water is reduced and industrial waste pollution in rivers as one source of clean water on the surface.  The Human need for clean water is directly proportional to the population growth in an area. In Balikpapan, which is the capital city of East Kalimantan Province has population 735,850 people by 2015, which represents 22% of total population of East Kalimantan.

This research is done by calculating the projection of clean water requirement in Balikpapan up to 20 years ahead and testing water quality by direct testing in the field using some tools that want to know the physical parameters contained in that water. The results obtained for needs of clean water have not been fullfilled and the water quality data distribution obtained from the test water sample Tirta Manggar PDAM has fullfilled the water requirements Class I.  In the calculation of clean water needs of Balikpapan City above, the percentage of non domestic with domestic demand is 50.30% its mean Balikpapan City have a lot of facility especially office and international company. Balikpapan City needs to immediately add the capacity of Intake because in 2017, Intake in Tirta Manggar PDAM is unable to meet the needs of clean water in Balikpapan City. Tirta Manggar PDAM Tirta Manggar has almost reached 80% service coverage, but loss of water equal to 36.92%, so Tirta Manggar PDAM must reduce water loss by 20%.
