Description Pipeline irrigation is an alternative in application of irrigation technology that theoretically has a higher efficiency than open channel irrigation. In application, a highly irrigation efficiency can only be achieved if pipeline irrigation designed and operated properly. Laboratory test shows that to dissolve sediment, flow velocity in pipe is recommended at least 0.5 m/sec. The result shows that on farm scale pipeline irrigation using gravitation in Cikurubuk, Buahdua Sub District, Sumedang District needs to pay attention to: (i) capturing consists of 3 (three) parts of the sediment trap, intake, and safety (strainer and overflow), (ii) intake discharge, water quality, and operation system (iii) pipeline system consisting primary, secondary, and tertiary must take into pipe depth, pipe fittings, and thrust block, (iv) complementary component of the pipeline irrigation system aims to keep it functioning properly. Complementary components consists of valve and drain valves, air vent, pressure gauge, water meter, and pressure release.
Irigasi pipa merupakan salah satu alternatif teknologi aplikasi irigasi yang secara teoritis mempunyai efisiensi lebih tinggi dibanding irigasi dengan saluran terbuka. Dalam penerapan di lapangan, efisiensi irigasi yang tinggi dapat dicapai apabila jaringan irigasi pipa dirancang dengan benar dan dioperasikan secara tepat. Hasil pengujian laboratorium menunjukkan untuk melarutkan sedimen dalam pipa kecepatan aliran disarankan minimal 0,5 m/detik. Hasil penerapan jaringan irigasi pipa skala hamparan petani secara gravitasi yang diterapkan di Desa Cikurubuk, Kecamatan Buahdua, Kabupaten Sumedang menunjukkan bahwa rancangan jaringan irigasi pipa di lapangan khususnya pada skala hamparan petani, perlu memperhatikan : (i) bangunan pengumpul yang terdiri dari 3 (tiga) bagian yaitu bangunan pengendap, bangunan pengambilan, dan bangunan pengaman (saringan dan pelimpah) (ii) debit pengambilan, kualitas air, dan sistem operasi jaringan, (iii) saluran pipa yang terdiri dari pipa primer, sekunder, dan tersier harus memperhitungkan penanaman pipa, sambungan pipa, dan bangunan penguat, (iv) komponen pelengkap pada sistem jaringan irigasi pipa bertujuan menjaga sistem jaringan agar tetap berfungsi dengan baik. Komponen pelengkap terdiri dari katup pengatur dan katup penguras, pelepas udara, pengukur tekanan, meteran air, dan bangunan pelepas tekan.
