Abstract: This paper analyzes the impending water and energy crisis in Davao City. Three statistical models namely linear, exponential, and cubic were used to predict future water and energy demands. The Tamugan River offers a potential source to address this looming problem, yet, it has become a source of conflict mainly between the Davao City Water District and Hedcor, Inc. The former is bent on harnessing the river which is known to have an abundance of high-quality surface water, while the latter proposes to establish cascaded hydropower plants given the river’s immense volume of flowing water. Notwithstanding the sincerity of both parties, the current conflict on who should harness the Tamugan River and how it be harnessed has to be resolved to avoid forestalling Davao City’s development.
