Abstract

The geographical location of Paciran sub-districts located on the coast causes a minimum supply of clean water because the community only relies on 2-3m shallow well water and PDAM water whose distribution is hampered by a long distance between the source of raw water and the service area, water production capacity is not sufficient and management is not healthy. This causes the availability of clean water in the northern coastal area of Lamongan Regency still does not meet the needs of the surrounding community. The purpose of this study is to propose waqf model to build clean water source infrastructure through synergy between Mineral Water Trading Company (PDAM) and productive waqf using third party assistance, namely investors as an effort to support infrastructure financing, known as the Triangle Synergy concept. The method used is descriptive qualitative. The primary data sources in this study are the results of observations and interviews with relevant speakers related to this research Secondary data sources are books and journals relating to productive waqf, infrastructure development, triangle synergy cooperation agreements. The results of the discussion show that, the level of efficiency and effectiveness of development is more easily realized if using the help of investors through the Triangle Synergy in financing infrastructure development.
