Mu gutwara intera ndende, agace ka serivise gafite uruhare runini mugutanga serivise yihuse nuburyo bworoshye bwurugendo rurerure kugirango borohereze umunaniro uzanwa namasaha menshi yo gutwara abashoferi nibinyabiziga. Ariko ubwiza bwakarere ka serivise bufite ubwiza bwabwo, serivise nyinshi zitukura net, gukundwa kwayo bizatuma abamotari benshi bahagarara, gukundwa, mubyukuri, muri make, sitasiyo ya serivise kumenyekana neza, ibidukikije nibyinshi ingenzi, izavuga ku kibazo gikomeye cyo gutunganya imyanda.
Umwanda w’ahantu hakorerwa imyanda harimo amazi y’ubwiherero, kugaburira amazi y’amazi, amazi y’amazi aturuka ku icumbi, icyatsi n’ibindi bice by’imyanda ituruka igihe amazi, ndetse no gukaraba imodoka, sitasiyo ya lisansi n’ibindi bice by’umwanda.
Bimwe mu bice byihariye bigize imyanda iva mu bice bya serivisi birashobora kugira ingaruka zidasanzwe ku bidukikije, guhera ku binyabuzima, biva mu myanda iva mu bice bya serivisi ahanini biva mu myanda iva mu biryo, amacumbi n’ibindi bikorwa. Ibi binyabuzima, iyo bisohotse mu bidukikije bitavuwe, birashobora kubora mikorobe mu bintu byangiza nka azote ya amoniya na hydrogen sulphide, bishobora kwanduza amazi n’ubutaka.
Amavuta n'amavuta nabyo ni igice cyingenzi cya puzzle. Amavuta hamwe namavuta mumyanda ituruka ahakorerwa serivisi ahanini biva mumyanda ituruka mubikorwa byo kugaburira. Amavuta, iyo asohotse mu bidukikije atabanje kuvurwa, arashobora gutwikira hejuru y’amazi, bikagira ingaruka ku guhumeka no gufotora kw’ibinyabuzima byo mu mazi, ndetse no kwanduza ubutaka munsi y’amazi. Azote ya Amoniya ivuye mubikorwa nkubwiherero irashobora gucikamo nitrite na nitrate na mikorobe. Ibi bintu bishobora kwanduza amazi y’amazi nkamazi yubutaka, inzuzi n’ibiyaga, biganisha kuri eutrophasi no kwangirika kw’amazi. Indwara zanduza imyanda iva mubikorwa nko gucumbika no gukaraba imodoka. Izi virusi, iyo zisohotse mu bidukikije bitavuwe, zishobora gutera indwara z’abantu n’inyamaswa nka infection enteric.
Kubwibyo rero, imyanda iva kuri sitasiyo ya serivise irakenewe rwose kugirango isukure hanyuma isohore hifashishijwe ishyirwaho ry’ibikorwa byo gutunganya imyanda, gushyira mu byiciro no kuyivura neza, no kuyitaho buri gihe, cyane cyane ko sitasiyo nyinshi za serivisi ziri mu turere twa kure dukikijwe n’icyaro, n'ingaruka kuri ibidukikije byo mucyaro nabyo biragaragara cyane. Ibintu kama, amavuta namavuta, azote ya ammonia nibindi bice bigize imyanda iva mukarere ka serivisi, iyo bisohotse mumigezi, ibiyaga ndetse nandi mazi y’amazi bitavuwe, bishobora guteza ibibazo nka eutrophasi no kwangirika kw’amazi, bikagira ingaruka ku mibereho y'ibinyabuzima byo mu mazi n'umutekano w'ikoreshwa ry'amazi y'abantu, kandi birashobora kwanduza ubutaka, bikagira ingaruka ku bwiza bw'ubutaka no gukura kw'ibihingwa, ndetse bikagira ingaruka ku bidukikije ndetse no ku buzima bw'abantu.
Nka rwiyemezamirimo mukuru mu gutunganya amazi y’amazi yegerejwe abaturage, Liding Environmental ifite uburambe bukomeye mu mishinga yo gutunganya amazi y’amazi kandi irashobora guhitamo igisubizo cyumvikana cyo gutunganya amazi mabi kuri sitasiyo ya serivisi, aho ubunyamwuga ari ngombwa muguhitamo ibikoresho byo gutunganya amazi mabi.
