Lake water consumed by the community in the Gresik upland area, Indonesia, contains contaminants that exceed the quality threshold. This research focuses on factors that can influence people's actions to adopt fixed bed filters and highlights strategies for the community to be willing to treat lake water before consuming it. This study builds an adoption of a fixed bed filter model and examines the effect of 15 factors (independent variables) on community actions to adopt the tool. A total of 248 samples from 3 villages were randomly selected to test the hypothesis. Data is collected, sorted, and analyzed statistically. Data analysis uses descriptive statistics and multiple linear regression analysis. Data representation, validation, and correlation of data are carried out in MS Excel and SPSS. The adoption of the fixed bed filter model shows that of the 15 factors analyzed, 3 factors significantly influenced the adoption decision (Sig. < 0.05): The elements, namely, attitudes toward water treatment, availability of infrastructure, and government assistance. One factor influences the decision on tool adoption quite significantly (Sig. < 0.1), namely the innovation of the lake water management agency. Several elements can carry out the development of the passage of fixed bed filters: Socializing contaminated water and water treatment, procurement of tools, assisting the adoption of tools, increasing the government's active role, and improving the performance of the lake water management agency. This model can be used to make the adoption of water treatment equipment models in other areas.
