Tamarunang is located approximately 10 km from Makassar, and about 4 km from the border of Makassar City and Gowa Regency. As a developing area, Tamarunang Village is a reference for developers to build urban communities houses. The urbanization makes the growth of housing development more rapid. This has an impact on rainwater catchment areas turned into residential housing areas. The problems faced in this community partnership programs are: 1) the living area of partner 1 and 2 have poor drainage and reduced rain water catchment areas, 2) the impact of poor drainage causes water to overflow and pool on the public roads and yard, 3) the garbage and sedimentation that accumulates in the drainage causes clogged water flow, 4) due to the development of housing construction, causing the flow direction and pattern of environmental drainage flow in the partner area to be unclear. The method used in this community partnership program is mentoring method and participatory rural approach (PRA) method. The mentoring method was carried out to change the community's paradigm of thinking in handling environmental drainage, increasing the community's understanding of environmental cleanliness and structuring, and facilitating partners in making infiltration drainage, flow direction maps, and environmental arrangement. The PRA method is carried out to arouse the partner's sense of belonging to the product to be developed, and the partner's sense of responsibility towards the products and environment that surrounds them. The main method adopted in this Community Partnership Program (PKM) activity is the time of presentation of counseling material, the method used is lecture, discussion, question and answer, and simulation, while during the practice of making infiltration drainage, the method used is demonstration. The results are the installation of biopori pipes, overflowing water and pooling on the road and the people's home page has been reduced, and rainwater does not cause standing water on the road and downstream of the housing area. And the construction of the drainage channel is intended
so that the drainage channel is not blocked again which can cause water to overflow into the highway
