Enhancing Flood Resilience in San Guillermo Village, Tinajero, Bacolor, Pampanga, Philippines: Evaluation of Current Drainage Design and Recommendation of The Provision of Cistern Tank with Pumping System

Abstract

Flooding is a problem that requires prompt attention as it endangers the health and safety of the general public, harms homes and businesses, and interrupts transportation and other important services. The physical and mental health of people can be negatively impacted by flooding in a variety of ways. Populations living in flood-prone locations may experience repeated flooding occurrences given predictions that both the frequency and severity of flooding events will continue to rise in the future. It is one of the most catastrophic natural disasters to hit the Philippines. San Guillermo Village, the study area for this research situated in Barangay Tinajero, Bacolor, Pampanga, has been consistently inundated with severe flooding. As a result, identifying a viable solution that will provide relief to the affected residents from the disastrous consequences of such flooding is paramount such as assessing the factors that contribute to flooding in the study area. The hydraulic performance of the existing storm drainage system design was assessed using Manning's equation and Rational Method, and a suitable drainage system design was proposed, including the installation of appropriately sized pipes to improve the system's performance. In addition, this study recommended suitable strategies to mitigate the effects of flooding in the area, such as the provision of a cistern tank with a pumping system. A more detailed calculation of the cistern tank's capacity and size was also conducted to ensure optimal water storage and usage. Overall, these recommendations aim to address the issue of flooding in the study area and to provide effective and sustainable solutions for the benefit of the affected residents.
