Ibiciro bibiri binini byuruganda rwo kumesa ni amafaranga yumurimo nigiciro cyamazi. Umubare wibiciro byakazi (usibye ibiciro bya logistique) mu nganda nyinshi zo kumesa ugera kuri 20%, naho igipimo cyamazi kigera 30%.Sisitemu yo gukarabairashobora gukoresha automatike kugirango igabanye ibiciro byakazi, kandi ibike amazi na parike. Na none, ibishushanyo bitandukanye bizigama ingufu za sisitemu yo gukaraba birashobora kongera inyungu zinganda zo kumesa.
Mugihe tugura sisitemu yo gukaraba, dukwiye gusuzuma niba izigama ingufu. Muri rusange, gukoresha ingufu za sisitemu yo gukaraba ni munsi ugereranije no gukoresha ingufu zo gukaraba no gukama. Nyamara, uko biri hasi bisaba gusuzumwa neza kuko ibi bifitanye isano n’uko uruganda rwo kumesa ruzabyara inyungu igihe kirekire mu gihe kiri imbere, n’inyungu rushobora kwinjiza. Kugeza ubu, amafaranga yumurimo yinganda zo kumesa hamwe no kugenzura neza (usibye ibiciro bya logistique) zingana na 15% -17%. Ibi biterwa na automatike yo hejuru hamwe nubuyobozi bunonosoye, ntabwo bigabanya umushahara w abakozi. Ibiciro byamazi bigera kuri 10% -15%. Niba amafaranga akoreshwa buri kwezi ari 500.000, kandi hakabaho kuzigama 10%, inyungu ya buri kwezi irashobora kwiyongeraho 50.000, ni 600.000 kumafaranga.
Imashini irakenewe muburyo bukurikira mu gihingwa cyo kumesa: 1. Gukaraba no gushyushya 2. Kuma igitambaro cyo kumisha 3. Gutera amabati hamwe nigitambara. Gukoresha amavuta muri ubu buryo biterwa n’amazi akoreshwa mu gukaraba, ubuhehere buri mu mwenda nyuma yo kubura umwuma, hamwe n’ingufu zikoreshwa mu cyuma.
Byongeye kandi, ubwinshi bwamazi akoreshwa mu gukaraba nabwo ni igice kinini cy’amafaranga yakoreshejwe mu ruganda rwo kumesa. Amazi akoreshwa mumashini asanzwe yinganda ni 1:20 (kg 1 yimyenda ikoresha kg 20 zamazi), mugihe amazi yo gukoreshasisitemu yo gukarabani bike, ariko itandukaniro muburyo buke buri kirango kiratandukanye. Ibi bifitanye isano nigishushanyo cyacyo. Igishushanyo mbonera cy’amazi meza gishobora kugera ku ntego yo kuzigama cyane amazi yo gukaraba.
Nigute ushobora gusuzuma niba sisitemu yo gukaraba ya tunnel ikoresha ingufu zituruka kuriyi ngingo? Tuzabisangiza nawe muburyo burambuye mu ngingo ikurikira.
