NIA MIMAROPA undertakes project feasibility study preparation seminar workhop headed by Regional Manager William P. Ragodon on March 12-15, 2019 for Batch 1 and March 19-22, 2019 for Batch 2 at Calapan City, Oriental Mindoro. Said activity aims to strengthen the knowledge and skills of Project in-Charge (PIC) or Irrigation Engineers, Irrigators Development Officers (IDOs) and Sr. Water Resource Facilities Technicians (SWRFTs). Regional Manager Ragodon and Engr. Myra B. Madriaga served as the resource speakers for the said activity.
Engr. Madriaga tackled the topic on project irrigation development program which involves the following activities: investigation, evaluation and selection, gathering of climatic data, soils survey, topographic survey, report preparation, project profiling to know whether the project is technically, economically & institutionally feasible.
She also explained the significance of conducting feasibility study where data from investigation and survey are used for preparing the plans and designs of the irrigation project. Poorly conducted and inadequate investigation have often resulted in high construction cost and serious problems in the operations and maintenance of the completed irrigation system
For the project investigation and survey, it has 4 processes including Preliminary investigation, Planning Data Gathering, Profile Writing and Final Project Feasibility Analysis.
Criteria for Selection of Projects
- TECHNICAL ASPECT
1.Expected cropping intensity is at least 130%.
2.Average slope of irrigable area is not more than 8%.
3.No problem on salinity, mine tailings and construction of complex structures.
4.No quarrying of the river within 1 km. upstream and 1 km. downstream of the proposed diversion dam.
- ECONOMIC ASPECT
- Internal Rate of Return is not less than 10% (updated by NEDA-Investment Coordination Committee (ICC) through a Memorandum dated Sep 30, 2016).
- Cost per hectare is less than P250,000 for new and P200,000 for rehab
- There should be no conversion of land use from productive permanent crops (coconut, orchards, etc.) to rice.
- Project is more than 30 has. for regular and at least 50 has. for foreign assisted projects except when it is for vegetables
- INSTITUTIONAL ASPECT
- At least 60% of the farmers are willing to organize into an association and amortize project cost.
- Irrigators’ Association is amortizing its loan; this is applicable when a proposed project is to rehabilitate an existing system with an outstanding loan.
- At least 60% of the irrigable area is not owned by only one landowner.
- Average size of landholding is 2 ha. or less
Engr. Ragodon stressed the roles of the irrigation engineers in the irrigation development program of the agency. From the hardware of irrigation like construction of dams and other irrigation facilities to the software which includes operation and maintenance. He also taught the participants how to compute the percolation and evaporation rate including water discharge.
To properly apply the learnings for the training, participants were instructed to prepare feasibility study report and submit them by the end of the seminar.
