Historically, the river was used to be a good route for transportation and an important source of water for the old Spanish Manila. However, the river is now very polluted due to human negligence and industrial development, and biologists consider it unable to sustain aquatic life. Many researchers have conducted studies on the Pasig River, unfortunately, no considerable progress from the point of view of purification process have succeeded. Hence, in this study, the use of fine-bubble technology for the purification of the polluted sludge from the said river is being explored. The critical point in using this technique is on the activation of the bacteria existing in the area using fine bubbles. The sludge is decomposed and purified by activating the aerobic bacteria after creating an aerobic state.

  • 1 Introduction
    Formulation of an Integrated River Basin Management and Development Master Plan for Marikina River Basin VOLUME 1: EXECUTIVE SUMMARY 1 INTRODUCTION The Philippines, through RBCO-DENR had defined 20 major river basins spread all over the country. These basins are defined as major because of their importance, serving as lifeblood and driver of the economy of communities inside and outside the basins. One of these river basins is the Marikina River Basin (Figure 1). Figure 1 Marikina River Basin Map 1 | P a g e Formulation of an Integrated River Basin Management and Development Master Plan for Marikina River Basin VOLUME 1: EXECUTIVE SUMMARY Marikina River Basin is currently not in its best of condition. Just like other river basins of the Philippines, MRB is faced with problems. These include: a) rapid urban development and rapid increase in population and the consequent excessive and indiscriminate discharge of pollutants and wastes which are; b) Improper land use management and increase in conflicts over land uses and allocation; c) Rapidly depleting water resources and consequent conflicts over water use and allocation; and e) lack of capacity and resources of stakeholders and responsible organizations to pursue appropriate developmental solutions. The consequence of the confluence of the above problems is the decline in the ability of the river basin to provide the goods and services it should ideally provide if it were in desirable state or condition. This is further specifically manifested in its lack of ability to provide the service of preventing or reducing floods in the lower catchments of the basin. There is rising trend in occurrence of floods, water pollution and water induced disasters within and in the lower catchments of the basin.

  • Impact of Climate Change on the Frequency and Severity of Floods in the Pasig-Marikina River Basin
    E3S Web of Conferences 117, 00005 (2019) https://doi.org/10.1051/e3sconf/201911700005 ICWREE2019 Impact of Climate Change on the Frequency and Severity of Floods in the Pasig-Marikina River Basin Cris Edward Monjardin1,*, Clarence Cabundocan1, Camille Ignacio1 and Christian Jedd Tesnado1 1School of Civil, Environmental and Geolocgical Engineering, Mapua University, 1002 Intramuros Manila, Philippines Abstract. This study assessed impacts of climate change on the frequency and severity of floods in the Pasig-Marikina River basin. Researchers used the historical data from PAG-ASA (Philippine Atmospheric, Geophysical and Astronomical Services Administration), specifically from Science Garden weather station. The historical data are coupled with a global climate model, the Hadley Center Model version 3 (HadCM3) to account for the natural variability of the climate system in the area. The observed data and the hydroclimatic data from HadCM3 was processed in Statistical Downscaling Model (SDSM) that results to rainfall data from 1961-2017 and change in temperature data from 2018-2048. A rainfall time series for the river basin was generated considering average seasonal effects in the area. A flood frequency curve was modelled. From that, flood value for 2048 was derived to be at 3950cu.m/s. Additionally, the rapid urbanization in the area has contributed to the changes in the river system making it more vulnerable to floods. The results of this study supports the claim that the Pasig-Marikina River basin will be affected by the climate variability in terms of the increase in rainfall depth and average temperatures, higher flood frequency and more massive floods in the future.

    Journal of Advanced College of Engineering and Management, Vol. 3, 2017 URBANIZATION AND RELATED ENVIRONMENTAL ISSUES OF METRO MANILA Ram Krishna Regmi Environment and Resource Management Consultant, Kathmandu, Nepal Email Address: [email protected] __________________________________________________________________________________ Abstract Due to rapid urbanization, Metro Manila is facing many environmental challenges with its continuous accelerating urban growth rate. According to 2010 census of population Metro Manila accounts about one-third of the total urban population and about 13% of the total national population of Philippines.The impact of urban growth of the Metro Manila to its urban environment relating on demography, solid wastes problem and problems in water bodies as well as air pollution and greenhouse gas emissionis emphasized here in this study.The flood prone areas within the Metro Manila is about 31%, most of the risk areas located along creeks, river banks or coastal areas.Metro Manila produces total garbage equivalent to 25% of the national waste generation in which about 17% is paper wastes and about 16% are plastics. In terms of water quality classification the upper reaches of the Marikina River is of Class A, but all remaining river systems are of Class C. Accordingly, the classification of Manila Bay is of Class SB. Similarly, the quality of ambient air of the Metro Manila is also poor. Using 2010 as base year, the major contributor to greenhouse gas is from vehicular emissions followed by the stationary sources. An urgent need is felt to incorporate environmental issues into planning its urban area to reduce the risks of further environmental degradation. Keywords: Metro Manila; urbanization; environmental issues; solid wastes;water quality; air pollution _________________________________________________________________________________ 1.
