This study aims to investigate the plan design and reduction of the runoff discharge using the eco-drainage system in the form of injection well. This research was conducted through an analysis of the injection well plan design at Graha Rektorat of the State University of Malang (SUM) and testing of soil permeability coefficient in the laboratory using Falling Head Permeability method. The result showed that design of injection wells using 1.5 m diameter and 3 m of depth for ten injection wells reduced drainage load by 44%, 34.35%, and 28.9% at return period of 2, 5, and 10 years respectively and the value of soil permeability coefficient was 2.01 cm/hour. © The Authors, published by EDP Sciences, 2018.
