Irrigation Facilities:
1 - National Irrigation System - a government irrigation system built or constructed and managed by the National Irrigation Administration to provide continuous supply of water for agricultural purposes to farmers in exchange for a fee.
2 - Communal Irrigation System - includes all irrigation facilities constructed by NIA and turned over to Irrigators Association (IA) upon completion. Operation and maintenance become the responsibility of the IA which in turn, collects direct operating cost of the project from farmer members.
3 - Pumps - an irrigation device provided personally by the operator for his farm's irrigation needs. It could be rented, borrowed or owned by him or any other members of his household. Examples are the Shallow Tubewell and Open Source Pump.
4 - Small Diversion Dam (SDD) - A channel and supporting ridge constructed across the slope to collect and divert run off. The purpose of this practice is to divert excess surface water from one area for use or safe disposal.
5 - Small Water Impounding Project (SWIP) - a structure constructed across a narrow depression or valley to hold-back water and develop a reservoir that will store rainfall and run-off during the rainy season for immediate or future use. Its structural height does not exceed 30 meters and has a volume storage not exceeding 50 million cubic meters. The average service area of SWIP is about 60 hectares (25-150 hectares)
6 - Small Farm Reservoir (SFR) - a smaller version of SWIP and is designed to collect and store rainfall and runoff for use in a single farm. It has a reservoir area of about 300 - 5,000 square meters and can serve 0.50 - 1.00 hectare. The embankment height above ground level is 4 meters and below. It can easily be constructed using manual digging or through a bulldozer. Irrigation is done with the use of a PVC siphon pipes or pumps.
