NIA used to solely operate and maintain national irrigation systems (NIS). These are now operated and maintained jointly with Irrigators Associations. Operation and maintenance (O&M) activities comprise of, among others, operation of storage and diversion dams; running of pumps; operation of gates, turnouts and drainage ditches; preparation and implementation of cropping and irrigation schedules; maintenance of the physical facilities including service and access roads, and repairs on minor damages caused by floods and typhoons.
There are 217 NIS nationwide with total area of 793,638 hectares as of end 2012. Thirty percent (30%) of the areas are served by reservoir-backed systems, 65 percent by run-of-the river diversion systems, and five percent by pump systems. The dominant crop in these areas is rice comprising 95 percent. The remaining 5 percent are corn, sugarcane, bananas and some vegetables.
The irrigation service fee (ISF) is charged by NIA from the beneficiaries in national systems as payment for the services rendered in the delivery of water.
NIA is authorized to collect ISF pursuant to the following laws:
PD 1702, Section 1 paragraph b:
(b) Operating capital – All amounts collected by the National Irrigation Administration as irrigation fees, administration charges, drainage fees, equipment rentals, proceeds from the sale of unserviceable equipment and materials, sale of all reparation goods allocated to the defunct irrigation service unit and the National Irrigation Administration, all other income shall be added to its operating capital.
Factors considered in setting the ISF rates are the system's scheme of development (run-off-the-river, reservoir and pump), crops planted, and season. These are denominated in kind, in cavans of palay (paddy) (one cavan = 50 kilograms) per hectare. Rates for pump systems are higher as the cost of power for pump operation is included in the computation. These vary from system to system because power rates are location-specific.
Pursuant to National Economic and Development Authority Resolution No. 20, series of 1978, it is a national policy that the government shall bear the cost of interests on all indebtedness for the construction of irrigation projects in order not to discourage the participation of farmer-beneficiaries in the development and operation of irrigation facilities.
NIA has been authorized to impose charges to generate revenues sufficient to cover only O&M costs of such facilities and to recover within a period not longer than 50 years, the monies initially invested in such facilities; provided that such charges shall not impair the user's incentive to avail of the benefits from irrigation and provided further, that such charges are within the beneficiaries' capacity to pay.
The ISF is primarily used to fund the O&M of national systems.

Dati, ang NIA lang ang nagpapatakbo at nagpapanatili ng mga national irrigation system (NIS). Ngayon, katuwang na nito ang mga Irrigators Association sa pagpapatakbo at pagpapanatili nito. Kasama sa mga gawain sa operation and maintenance (O&M), bukod sa iba pa, ang pagpapatakbo ng mga storage at diversion dam; pagpapaandar ng mga pump; pagpapatakbo ng mga gate, turnout, at drainage ditch; paghahanda at pagpapatupad ng mga iskedyul ng pagtatanim at patubig; pagpapanatili ng mga pisikal na pasilidad kabilang ang mga service at access road, at pagkukumpuni ng maliliit na pinsalang dulot ng baha at bagyo.
May 217 NIS sa buong bansa na may kabuuang lawak na 793,638 hectares hanggang katapusan ng 2012. Tatlumpung porsyento (30%) ng mga lugar ay pinaglilingkuran ng mga sistemang may reservoir, 65 percent ng mga run-of-the river diversion system, at limang percent ng mga pump system. Ang pangunahing pananim sa mga lugar na ito ay palay na bumubuo ng 95 percent. Ang natitirang 5 percent ay mais, tubo, saging, at ilang gulay.
Ang irrigation service fee (ISF) ay sinisingil ng NIA sa mga benepisyaryo sa mga national system bilang bayad sa mga serbisyong ibinigay sa paghahatid ng tubig.
Awtorisado ang NIA na mangolekta ng ISF alinsunod sa mga sumusunod na batas:
PD 1702, Section 1 paragraph b:
(b) Operating capital – Lahat ng halagang kinokolekta ng National Irrigation Administration bilang irrigation fee, administration charge, drainage fee, upa sa mga equipment, kita mula sa pagbebenta ng mga hindi na mapakikinabangang equipment at materyales, pagbebenta ng lahat ng reparation goods na inilaan sa dating irrigation service unit at sa National Irrigation Administration, lahat ng iba pang kita ay idaragdag sa operating capital nito.
Ang mga salik na isinasaalang-alang sa pagtatakda ng mga ISF rate ay ang scheme of development ng sistema (run-off-the-river, reservoir at pump), mga pananim na itinanim, at panahon. Ang mga ito ay nasa anyong produkto, sa cavan ng palay (isang cavan = 50 kilograms) bawat ektarya. Mas mataas ang mga rate para sa mga pump system dahil kasama sa pagkwenta ang gastos sa kuryente para sa pagpapaandar ng pump. Nag-iiba-iba ito sa bawat sistema dahil ang mga rate ng kuryente ay depende sa lugar.
Alinsunod sa National Economic and Development Authority Resolution No. 20, series of 1978, pambansang patakaran na sasagutin ng pamahalaan ang gastos sa interes sa lahat ng pagkakautang para sa pagpapatayo ng mga irrigation project upang hindi mawalan ng gana ang mga magsasakang-benepisyaryo na lumahok sa pagpapaunlad at pagpapatakbo ng mga pasilidad ng patubig.
Awtorisado ang NIA na magpataw ng mga singil upang makalikom ng sapat na kita na sasaklaw lamang sa mga gastos sa O&M ng mga naturang pasilidad at upang mabawi sa loob ng panahong hindi lalampas sa 50 years, ang mga perang unang inilaan sa mga naturang pasilidad; basta't ang mga naturang singil ay hindi makasisira sa kagustuhan ng gumagamit na makinabang sa patubig at basta't ang mga naturang singil ay kaya pang bayaran ng mga benepisyaryo.
Pangunahing ginagamit ang ISF upang pondohan ang O&M ng mga pambansang sistema.
