Rehabilitation Program of Lambiki River: A Proposed Aeration Design and Sustainable River Management Plan in Brgy. Sta. Teresa 2nd, Lubao, Pampanga

The Environmental Management Bureau (EMB) in the Philippines has identified 14 rivers needing waterquality monitoring and potential rehabilitation. This research focuses on creating a program to restore theLambiki River in Brgy. Sta. Teresa 2nd, Lubao, Pampanga, through sustainable water management.Objectives include evaluating water quality parameters like Biochemical Oxygen Demand (BOD),Chemical Oxygen Demand (COD), and Dissolved Oxygen (DO); testing a prototype aeration system;identifying causes of water quality deterioration; and devising a river management strategy. Usingquantitative methodologies and mixed methods, the study conducted water laboratory tests and anInterpretative Phenomenological Approach (IPA). Initial water quality did not meet standards set by DAO2021-19 for fisheries but improved after implementing the prototype aeration system for three and sevendays. Findings pointed to overpopulation and community practices as key factors in water quality decline.The river management plan developed emphasizes community involvement, environmental education, andinnovative strategies, highlighting the importance of engaging communities, raising environmentalawareness, and employing sustainable methods to address water pollution and foster growth.
