Uphononongo lweSizwe lokususa izondlo kunye neeTekhnoloji zeSibini-isivamvo somgangatho wamanzi

Uphononongo lweSizwe lokususa izondlo kunye neeTekhnoloji zeSibini
I-EPA ihlola iindlela ezisebenzayo nezingabizi kakhulu zokususa izondlo kwiindawo zonyango eziphethwe ngurhulumente (i-POTW). Njengenxalenye yophando lukazwelonke, le arhente yenze uphando lwee-POTW phakathi kowama-2019 nowama-2021.

Ezinye iiPOTW zongeze iinkqubo ezintsha zonyango ukususa izondlo, kodwa olu phuculo lusenokungabi naxabiso lifikelelekayo okanye lungadingeki kuzo zonke izibonelelo. Olu phononongo lunceda i-EPA ifunde ngezinye iindlela iiPOTW ezinciphisa ngazo ukukhutshwa kwazo kwezondlo, ngelixa ziphucula iindlela zokusebenza nokugcinwa kwazo, kwaye ngaphandle kokusebenzisa iindleko ezinkulu zemali. Olu phononongo luneenjongo ezintathu eziphambili:

Fumana ulwazi kuzwelonke malunga nokususwa kwezondlo.
Khuthaza ukuphucula ukusebenza kwePOTW ngeendleko eziphantsi.
Nika iqonga labathathi-nxaxheba ukuze babelane ngeendlela ezilungileyo zokusebenza.
Iingenelo kwi-POTWs
Olu phononongo luza:
Nceda iiPOTWs ziphucule ukususwa kwezondlo ngokubonelela ngolwazi lokusebenza kunye nokusebenza oluvela kwiintlobo ezifanayo zePOTWs esele zifikelele kwiindlela eziphumelelayo nezingabizi kakhulu zokususwa kwezondlo.
Sisebenza njengomthombo wedatha omtsha kuzwelonke malunga nokususwa kwezondlo ukunceda abachaphazelekayo ukuba bavavanye kwaye baphuhlise amaxabiso okunciphisa izondlo anokufezekiswa.
Nika isiseko sedatha esityebileyo sokusebenza kokususwa kwezondlo kwi-POTWs, kumazwe, abaphandi bezemfundo, kunye nabanye abantu abanomdla.
IiPOTW sele zibone iingenelo zokuphucula ukutya okungabizi kakhulu. Ngo-2012, iSebe leMigangatho yoBume beNdalo laseMontana laqala ukuqeqesha abasebenzi bePOTW kurhulumente malunga nokususwa kwezakhamzimba kunye nokwenza ngcono ukutya. IiPOTW ezazinabasebenzi ababandakanyeka ngokupheleleyo kwinkqubo yokwenza ngcono ukutya zinciphise kakhulu ukukhutshwa kwazo kwezakhamzimba.

Ukususwa Kwezondlo Kuphunyeziwe Kuzwelonke
Iziphumo zokuqala zemibuzo yovavanyo zinceda ukubonisa inkalo ebalulekileyo yoPhando lweSizwe: ukususwa kwezondlo okuphuculweyo kunokufikelelwa zizo zonke iintlobo zePOTW. Iziphumo zophando ukuza kuthi ga ngoku zibonisa ukuba iiPOTW ezingaphezu kwe-1,000 ezineentlobo ezahlukeneyo zonyango lwebhayoloji (kuquka zombini ubuchwepheshe bonyango oluqhelekileyo noluphambili) zinokufikelela kwi-nitrogen epheleleyo ye-8 mg/L kunye ne-phosphorus iyonke ye-1 mg/L. Umfanekiso ongezantsi ubandakanya ezo POTW ezinabantu abakhonzwa ubuncinane ngabantu abangama-750 kunye nokuhamba komthamo woyilo ubuncinane iigaloni ezi-1 yezigidi ngosuku.
