Ubwiherero buciriritse, ikintu cy'ingenzi mu buzima bwacu bwa buri munsi, bwagiye buhinduka cyane mu myaka yashize. Mu batangije udushya mu bwiherero, American Standard igaragara nk'ikirango gifitanye isano n'ubwiza, imikorere myiza, n'ihumure. Muri iyi nkuru yuzuye y'amagambo 5000, tuzasuzuma iterambere ry'Ubunyamerika.Ubwiherero busanzwe, basuzuma iterambere ryabo mu ikoranabuhanga, udushya mu gushushanya, n'ingaruka bagize ku bunararibonye bwabo mu bwiherero.
I. Uko amateka ateye:
Kugira ngo dusobanukirwe urugendo rwaUbwiherero busanzwe bwa Amerika, tugomba kubanza gushakisha imizi y’amateka y’isuku ya none. Kuva ku nkono z’ibanze z’imico ya kera kugeza ku miyoboro y’amazi mabi yo mu kinyejana cya 19, ubwiherero bwageze kure. American Standard, yashinzwe mu 1875, yagize uruhare runini mu gushyiraho inzira yo gushushanya ubwiherero. Tuzasuzuma intambwe z’ingenzi mu mateka y’iyi sosiyete n’uruhare rwayo mu iterambere ry’ibikoresho by’ubwiherero.
II. Iterambere ry'ikoranabuhanga:
American Standard yakomeje gushyira imbere ikoranabuhanga ry’ubwiherero. Kuva ku ishyirwaho ry’imashini igabanya ubushyuhe kugeza ku iterambere ry’udushya two kuzigama amazi, buri terambere rigaragaza ubwitange mu gukora neza no kurambye. Iki gice kizatanga isesengura ryimbitse ry’imikorere y’ikoranabuhanga itandukanya ubwiherero bwa American Standard, harimo uburyo bukomeye bwo kuzigama amazi, ikoranabuhanga rizigama amazi, n’uburyo bw’ubwiherero bugezweho.
III. Imiterere y'igishushanyo:
Uretse imikorere, American Standard yabaye ingenzi mu bijyanye n'ubwiza bw'igishushanyo.imiterere y'ubwiherero, ibikoresho, n'ibishushanyo mbonera bigaragaza impinduka mu byo abaguzi bakunda n'uburyo bigezweho mu miterere. Tuzasuzuma uburyo American Standard yakiriye udushya mu miterere, kuva ku myambarire ya kera n'iy'igihe gito kugeza ku miterere igezweho n'iy'ubukorikori. Byongeye kandi, tuzasuzuma ingaruka z'umuco n'imibereho ku miterere y'ubwiherero.
IV. Ingaruka ku busugire bw'ibidukikije:
Muri iki gihe cyo kongera ubumenyi ku bidukikije, American Standard yashyize imbere uburyo bwo kubungabunga ubwiherero burambye. Iki gice kizareba imbaraga z'ikigo mu kugabanya ikoreshwa ry'amazi, kugabanya ingaruka ku bidukikije binyuze mu bikoresho bitangiza ibidukikije, no kwimakaza uburyo bwo gukora ibintu mu buryo burambye. Tuzaganira kandi ku ruhare rwa American Standard mu guteza imbere kubungabunga amazi no kwita ku bidukikije mu nganda zikora amazi.
V. Ubunararibonye bw'umukoresha n'ihumure:
Igice cy'ingenzi cyaigishushanyo mbonera cy'ubwihereroni ubunararibonye bw'abakoresha n'ihumure. American Standard yakomeje kwibanda ku gukora ubwiherero butuma ubwiherero burushaho gukora neza, ndetse bunatuma ubwiherero burushaho kumererwa neza. Iki gice kizasuzuma imiterere y'imiterere y'ubwiherero, imiterere yoroshye gukoreshwa, n'udushya tugamije kunoza isuku no koroshya ubuzima.
VI. Imbogamizi n'ibyitezwe mu gihe kizaza:
Nta rugendo rutagira imbogamizi, kandi American Standard yahuye n’imbogamizi nyinshi mu isi y’ipiganwa ry’ibikoresho byo mu bwiherero. Iki gice kizaganira ku mbogamizi ikigo cyatsinze, nko guhangana ku isoko, impinduka mu mategeko, n’ihungabana ry’ikoranabuhanga. Byongeye kandi, tuzatekereza ku mahirwe y’ubwiherero bwa American Standard mu gihe kizaza, tukareba intambwe zigaragara mu ikoranabuhanga, imiterere, n’uburyo burambye.
Mu gusoza, iterambere ry’ubwiherero bwa American Standard ni urugendo rushimishije mu mateka, ikoranabuhanga, imiterere, no kubungabungwa. Kuva yatangira mu kinyejana cya 19 kugeza ku mwanya wayo nk'umuyobozi ku isi mu by'ubwiherero, American Standard yakomeje kugira uruhare mu buryo tubona kimwe mu bintu by'ingenzi mu isuku igezweho. Mu gihe tureba ahazaza, biragaragara ko American Standard izakomeza kugira uruhare runini mu gushyiraho amahame yo kwisanzura no guhanga udushya mu miterere y’ubwiherero.
