Rural coastal communities have very simple housing conditions. Another view that is often encountered is the poor condition of the environment and pollution with a very minimal infrastructure system. Sanitation facilities and infrastructure in a fishermen's settlement environment are not or less available, if there are then the conditions are inadequate or not feasible. One of the sanitation networks that exist in settlements and has a worrying condition is household waste water sanitation. Without proper management, liquid waste can cause various infectious diseases. but in some poor communities in developing countries, especially in rural areas, people try to dispose of liquid waste as cheaply as possible, in the absence of a sanitation system some people depend on natural processes. Inadequate liquid waste disposal systems are rarely considered a problem by the community. The aim to be achieved is to find out the characteristics of the household waste sanitation system in the form of gray water that exists in fisherman settlements and the appropriate form of handling in accordance with community conditions and environmental conditions. The method used is qualitative observational which is naturalistic
