The aim of this study is to decide the strategy of mitigating the quality of river water of the Surabaya River as raw source for drinking water. The study was carried out during both the rainy (January – February 2021) and dry seasons (September – October 2021). Research sampling uses random sampling in term of observation at four Locations with different activities. The sample obtained was tested for its quality of water indicators, such as temperature, brightness, pH, dissolved oxygen, organic matter, nitrates,and phosphates). The results showed that indicator of pH, temperature, and nitrates, met class II water qualitystandards. However, indicators of dissolved oxygen, organic matter, and phosphates had not met class II as stated in the Regulation of Government 82/2001. Lightly pollution identified the water quality status of the Surabaya River in the rainy and dry seasons. As a result, efforts to mitigate water quality were required,including regulating water infiltration, monitoring water quality at water sources, conducting afforeLocation programs, reorganizing settlements and industries on watershed banks, and incorporating biological treatment using biofilter technology into the Surabaya River's initial water treatment process.
