Munroe island had suffered wide destruction in the tsunami of 2004. Located at the confluence of the Ashtamudi Lake and the Kallada River in Kollam district, Munroe island was created by the land reclamation from the delta and hence vulnerable to flooding. The agriculture sector and fishing sector had suffered worst. Rising of water level due to high tide and seepage of saline water from Ashatamudi lake are the main threat in this island. The island chosen has high frequency of flooding, leading to settlement and collapse of buildings (sanitation unit) and unsafe sanitation. The main treat in the island is the expulsion of ground water from toilet and it spread over the surrounding land create unhygienic condition. The Kerala Rural Water Supply and Sanitation Project broke new ground by institutionalizing the integration of local communities with Panchayats (local government institutions). The logistical analysis is the useful tool for the identification of problems behind poor sanitation technology and structured with possible solution by problem tree and solution tree methods. The study attempts to give solutions to managing flooding as well as to the sanitation problem. Sewage is the part of wastewater that is contaminated with feces or urine, but is often used to mean any wastewater. Suitable sanitation network as per the site condition is being studied in comparison with the other networks of drainage system and analysis the gap between the need of society and the technology. Conversion of sewage waste to fertilizer is the sustainable solution for the agricultural reform by suitable sanitation technology like Ecological Sanitation (EcoSan). Decentralized wastewater treatment can be a sensible solution for communities of any size and demographic. Like any other system, decentralized systems of number of units in the islands must be properly designed, maintained, and operated to provide optimum benefits. GIS and GPS are the useful tool for the designing the network system. A sewage treatment plant (STP) has to handle the designed

quantity of sewage and deliver satisfactory quality of treated water, on a consistent, sustained basis over long term. STP designing is based on various criteria like the population in the islands, economical aspect, minimum water pollution, availability of land, size of treatment plant etc. Multi-unit of treatment plant in different island will create a network of drainage system as per site requirement. Improved sanitation also helps the environment by minimizing the river pollution. Clean drinking water and good sanitation would not prevent infections without practicing good hygiene.
