Flood events often have severe socio-economic impacts, such as loss of lives and livelihoods, food, water and energy scarcity, and adverse impacts on human health and the environment. As far as feasible, human interference into the processes of nature should be reversed, compensated and, in the future, prevented. This study explores the possible solutions for the drainage system to ensure peak performance that might be adopted in España Boulevard, Manila. It aims to describe the wastewater management system to prevent and protect the adverse impact of flood events on human health and safety, on valuable goods and property, and on the aquatic and terrestrial environment.

Potable water is a commodity and basic necessity of life for which metropolitan areas and adjacent areas are to pay. Water from Manila Waterworks and Sewerage System (MWSS) has also become a problem considering the low water supply coming from their sources. Because of El Nino phenomena and other problems of the water system, rationing Metro Manila was implemented. This descriptive study aimed to assess the performance and effectiveness of community water supply management in terms of the quality of water such taste, odor, color, sediments, service and cost and design water safety plan for the community. Purposive sampling was used to determine the participation of the knowledgeable homeowners of Karangalan Village in the province of Rizal. Some interesting insights of the study are: Potable water is the water delivered to the homeowners. However, there are sediments and brownish color observed in the water due to pipe corrosion. In terms of service, the performance of the water system delivered to the homeowners is acceptable based on the volume delivery, accessibility, availability, promptness, and reliability. Homeowners who use potable water are satisfied in terms of its efficiency, effectiveness, user-friendly, promptness and expandability. Water safety plan is an integral part of the whole planning process and helps improve the management of Karangalan village water supply and may be undertaken or updated at any time

Flooding is a natural event that replenishes the groundwater and revitalizes the soil through the deposit of sediments. However, when communities settle within floodplains, flooding can cause adverse social, economic and environmental impacts. Flood protection works, such as dikes, can further reduce flood risk. These structures particularly relevant in protecting historic communities that were settled before floodplain management policies were implemented. However, it is technically and economically impossible to completely eliminate flood risk with dikes. During severe floods, dike failures may occur due to erosion, overtopping or seepage. This study predicts that dike construction may lead to water level lowering for in-bank flows and to water level increases for out-of-bank (flood) flows. This confirms that, in principle, the existing Pampanga dike and specifically on the construction of Taguig City dike along the Laguna Lake may have contributed to the observed flood water level trends in the Metro Manila.

Floods have large environmental consequences for communities and individuals. As most people are aware, the immediate impacts of flooding include loss of human life, damage to property, destruction of plants and trees, and deterioration of health conditions owing to waterborne diseases. For decades, Manila City has been battling with flood risk. The area has been inundated with flood waters several times, whether it is due to tropical weather, strong rain fall events, or rising waters. This has resulted in millions of pesos in damages, and in some instances, the same home has been affected multiple times. Given the age of the existing Quiapo pump station even with current upgrades and the potential development of other areas within the catchment area, there is a need to identify, review, and recommend some alternatives solution for the future of the Quiapo pump station. The researcher is thus undertaking this study to review alternatives for upgrades or replacement of the existing Quiapo pump station. It aims also to describe the common plants and trees damaged by typhoons and floods, animals affected by devastating floods, common diseases during floods, effectiveness of existing pumping stations and advantages of the new pumping station, the effects of high floods on trees, animals and human health, and the impact of some alternatives solutions of the Quiapo pump station on natural environment to prevent and protect the adverse impact of flood events on human health and safety, on valuable goods and property, and on the aquatic and terrestrial environment.
