Kwiindawo zasemaphandleni, uninzi alubandakanywanga kuthungelwano lwemijelo yamanzi amdaka ngenxa yemida yendawo, yezoqoqosho neyezobugcisa. Oku kuthetha ukuba unyango lwamanzi amdaka asekhaya kwezi ndawo lufuna indlela eyahlukileyo kuneyezixeko.
Kwiindawo zasezidolophini, iinkqubo zonyango lwendalo ziyindlela eqhelekileyo yokunyanga amanzi amdaka. Le ndlela isebenzisa amandla okucocwa kwendalo komhlaba, izityalo kunye nezidalwa ezincinci ukunyanga amanzi amdaka asekhaya. Imizekelo ibandakanya iindawo ezimanzi, amachibi kunye neenkqubo zokunyanga umhlaba. Ezi nkqubo zihlala zingenisa amanzi amdaka asekhaya kwindawo ethile kwaye zicoce amanzi amdaka ngokusebenzisa isenzo sokufunxa nokucoca umhlaba nezityalo, kunye nesenzo esonakalisayo sezinto ezincinci. Iingenelo zale ndlela kukuba ixabisa kancinci, kulula ukuyigcina kwaye inobuhlobo nokusingqongileyo. Nangona kunjalo, ineengxaki zokusebenza kakuhle konyango kwaye ifuna indawo enkulu yomhlaba.
Kwezinye iilokishi ezinkulu, okanye kwiindawo zokuhlala ezixineneyo, kunokwakhiwa izitishi zokunyanga amanzi amdaka ezikwindawo enye. Olu hlobo lwesitishi sokunyanga ludla ngokugxininisa amanzi amdaka asekhaya avela kuluntu luze emva koko lwenze unyango olufanayo ngokwasemzimbeni, ngokwekhemikhali nangokwebhayoloji. Ukungcola okucociweyo kudla ngokucocwa, kucocwe kwaye kususwe i-phosphorus, kwaye kukhutshwe emva kokuba kuhlangatyezwane nemigangatho yokukhutshelwa. Iingenelo zolu hlobo lokunyanga kukuba lunamandla amakhulu okunyanga kunye nokusebenza kakuhle; ingxaki kukuba lufuna imali eninzi kunye nezixhobo ukuze lutyalwe ekwakhiweni nasekusebenzeni kwalo.
Ngaphandle kweendlela ezibonakalayo nezobunjineli ezikhankanyiweyo apha ngasentla, urhulumente ukwadlala indima ebalulekileyo ekuphathweni kwamanzi amdaka asekhaya kwiilokishi. Urhulumente unokukhokela abemi kunye namashishini ukuba banikele ingqalelo engakumbi ekuphathweni kwamanzi amdaka kunye nokukhuselwa kwendalo ngokuqulunqa imigaqo-nkqubo efanelekileyo, efana neentlawulo zamanzi amdaka kunye nezikhuthazo zokukhuselwa kwendalo. Kwangaxeshanye, ngemfundo kunye nokwazisa, ukuphakamisa ulwazi lwabemi ngokukhuselwa kwendalo, ukuze bakwazi ukuthatha inxaxheba ngakumbi kwinkqubo yokunyangwa kwamanzi amdaka asekhaya.
Kwezinye zeendawo eziphuhlileyo, izixhobo zokucoca amanzi amdaka ezisetyenziswa ekhaya nazo ziyindlela eqhelekileyo yokukhetha. Olu hlobo lwezixhobo ludla ngokufakelwa ebaleni okanye kufutshane nosapho ngalunye, kwaye lunokusetyenziselwa ukunyanga amanzi amdaka asekhaya aveliswa lusapho oluhlala kulo. Ezi zixhobo zinezinto ezininzi zangaphakathi ezifana nokuhluzwa ngokwasemzimbeni, ukusabela kwamakhemikhali kunye nokubola kwezinto eziphilayo, ezinokususa izinto eziphilayo, i-nitrogen, i-phosphorus kunye nezinye izinto emanzini amdaka asekhaya. Inzuzo yolu hlobo lwezixhobo kukuba ziguquguquka kwaye zilula, kwaye zingafakwa kwaye zisetyenziswe naphi na nangaliphi na ixesha.
Ngamafutshane, unyango lwelindle lasekhaya kwiindawo zasezidolophini ezingabandakanywanga kuthungelwano lwelindle yingxaki ebanzi efuna ukudityaniswa kweendlela ezahlukeneyo kunye nobuchwepheshe bonyango. Ekukhetheni izixhobo zokunyanga amanzi amdaka ezidibeneyo zasezidolophini, iLiding Environmental Protection inokubonelela ngezisombululo kunye nezixhobo ngokweemfuno ezahlukeneyo kunye neemeko zokwenyani.
