Ucwaningo Lukazwelonke Lokususwa Kwezakhamzimba kanye Nobuchwepheshe Besibili – Inzwa Yekhwalithi Yamanzi

Ucwaningo Lukazwelonke Lokususwa Kwezakhamzimba kanye Nobuchwepheshe Besibili
I-EPA ihlola izindlela ezisebenzayo nezingabizi zokususa izakhamzimba ezindaweni zokwelapha eziphethwe ngumphakathi (i-POTW). Njengengxenye yocwaningo lukazwelonke, le nhlangano yenze ucwaningo lwama-POTW phakathi kuka-2019 no-2021.

Amanye ama-POTW anezele izinqubo ezintsha zokwelapha ukuze kususwe izakhamzimba, kodwa lokhu kuthuthukiswa kungase kungabi yinto engabizi noma engadingeki kuzo zonke izikhungo. Lolu cwaningo lusiza i-EPA ukuthi ifunde ngezinye izindlela ama-POTW anciphisa ngazo ukukhishwa kwawo kwezakhamzimba, ngenkathi enza ngcono imikhuba yokusebenza nokulungisa, futhi ngaphandle kokufaka izindleko ezinkulu zemali. Lolu cwaningo lunezinhloso ezintathu eziyinhloko:

Thola ulwazi lukazwelonke mayelana nokususwa kwezakhamzimba.
Khuthaza ukusebenza kwe-POTW okuthuthukisiwe ngezindleko ezincane.
Nikeza inkundla yababambiqhaza ukuze babelane ngemikhuba emihle kakhulu.
Izinzuzo kuma-POTW
Ucwaningo luzokwenza lokhu okulandelayo:
Siza ama-POTW ukuthi athuthukise ukususwa kwezakhamzimba ngokunikeza ulwazi lokusebenza kanye nokusebenza okuvela ezinhlotsheni ezifanayo zama-POTW asevele efinyelele izindlela eziphumelelayo nezingabizi zokususwa kwezakhamzimba.
Sebenza njengomthombo wedatha omusha omkhulu kazwelonke mayelana nokususwa kwezakhamzimba ukusiza abathintekayo ukuhlola nokuthuthukisa amanani okunciphisa izakhamzimba angafinyeleleka.
Nikeza isizindalwazi esicebile sokusebenza kokususwa kwezakhamzimba kuma-POTW, izifundazwe, abacwaningi bezemfundo, kanye nabanye abantu abanentshisekelo.
Ama-POTW asevele ebone izinzuzo zokwenza ngcono ngezindleko eziphansi. Ngo-2012, uMnyango Wekhwalithi Yezemvelo waseMontana waqala ukuqeqesha abasebenzi be-POTW esifundazweni ngokususwa nokuthuthukisa izakhamzimba. Ama-POTW abasebenzi bawo abahlanganyele ngokugcwele enkambisweni yokwenza ngcono banciphise kakhulu ukukhishwa kwawo kwezakhamzimba.

Ukususwa Kwezakhamzimba Kufeziwe Kuzwelonke
Imiphumela yokuqala yemibuzo yokuhlola isiza ukukhombisa isici esibalulekile seSifundo Sikazwelonke: ukususwa okuthuthukisiwe kwezakhamzimba kuyatholakala yizo zonke izinhlobo zama-POTW. Imiphumela yocwaningo kuze kube manje ikhombisa ukuthi ama-POTW angaphezu kuka-1,000 anezinhlobo ezahlukene zokwelapha eziphilayo (kufaka phakathi ubuchwepheshe bokwelapha obujwayelekile nobuthuthukisiwe) angafinyelela i-nitrogen ephelele engu-8 mg/L kanye ne-phosphorus ephelele engu-1 mg/L. Isithombe esingezansi sihlanganisa lawo ma-POTW anenani labantu abakhonzwa okungenani abantu abangu-750 kanye nokugeleza kwamandla okuklama okungenani amalitha ayisigidi esingu-1 ngosuku.
