Feasibility Study of Proposed Tibangran Small Reservoir Irrigation Project
Country: Philippines
PRIMEX provided the services of four specialists in the consultant team: (i) a Geologist, who reviewed/updated geodelogic parameters and tested considered in previous studies; conducted the required geologic and geotechnical mapping, surface geological mapping, sub-surface geological investigation, seismic analysis on damsite, slope stability analysis on damsite’s abutments; and provided recommendations on the safety and stability of the foundation; (ii) an Irrigation and Drainage Engineer, who reviewed/updated design and cost parameters of irrigation and drainage structures considered in previous studies in coordination with other key experts; provided a location map showing the name, location, and the general description of the project; assessed drainage system and improvement needs in the project area; determined the water requirements for crops to be grown in the service area and based on conveyance and farm level efficiencies, determined irrigation water requirement; prepare feasibility level design of irrigation canals and associated control structures and measurement facilities as well as other required supporting infrastructure as well as farm level facilities, drainage channels, drainage structures; showed the cost of the annual O&M of irrigation facilities; and recommended and adopted innovations/other available alternatives or technology into the design of canal and drainage systems improvement that would improve farming operation through the service area; (iii) a Soil and Land Classification Specialist, who reviewed/updated soil and land classification data/analysis considered in previous studies; collected, updated, reviewed, and validated any soil and land classification report, publications, and other references such as FS reports related to project concerned; collated and studied the existing available soils and land resources data; performed slope quantification or the determination and delineation for the various slope class based on topographic maps; performed semi-detailed soil and land classification survey using topographic maps and satellite imagery printouts and termine possible location of boreholes and master pits in the potential service area; conducted soil profiling and collected soil samples that would be subjected to physical and chemical analysis in order to facilitate the fertilizer recommendation for the different crops to be grown in the area; and carried out land use mapping, soil characterization, and land class correlation based on the inherent and morphological characteristics of the solid such as physical and chemical properties, topography, drainage and parent materials, and design into appropriate mapping units for the report, and (iv) an Environment and Social Assessment Specialist, who reviewed/updatied environmental and social assessment parameters considered in previous studies. Prepared the Social and Environmental Impact Assessment (SEIA) Study Report of the Project inclusive of all its components and consistent with the requirement of NIA and the prescribed guidelines of the Department of Environment and Natural Resources (DENR) Administrative Order No. 2003-30 and its Revised Procedural Manual for the acquisition of Environmental Compliance Certificate.
