Ulawulo lwe-sludge yase-US kunye nobungakanani bemakethi yokukhupha amanzi kulindeleke ukuba ifikelele kwi-USD 3.88 yezigidigidi ngo-2030 kwaye kulindeleke ukuba yandise kwi-CAGR ye-2.1% ukusuka ngo-2024 ukuya ku-2030.
Sinokubonelela ngeenzwa zokujonga ilindle, kwaye sinezinzwa zomgangatho wamanzi ezifanelekileyo kwiimeko ezahlukeneyo zesicelo, wamkelekile ukutyelela.
Ulwakhiwo lwezi zixhobo zitsha zokucoca lwenzelwa ukujongana nomthamo omkhulu wodaka kunye namanzi amdaka aveliswa ziindawo zokuhlala, zorhwebo, kunye nemisebenzi yemizi-mveliso. Oku, ke, kulindeleke ukuba kube negalelo kwimfuno yolawulo lodaka kunye nokucocwa kwamanzi e-US ngexesha lengqikelelo.
Ukunyuka kwabemi e-US kunegalelo kwisidingo sezityalo ezintsha zokucocwa kwamanzi amdaka. Njengoko abantu besanda, umthamo wamanzi amdaka aveliswayo nawo uyenyuka ngokulinganayo. Abantu abaninzi bathetha imisebenzi emininzi yokuhlala, yorhwebo, kunye nemizi-mveliso. Zonke ezi zinto zinegalelo ekwandeni kwemveliso yamanzi amdaka kweli lizwe. Kukho ulwazi olukhulayo loluntu malunga nokukhuselwa kwendalo kunye nokuzinza. Olu tshintsho lwentlalo lutyhala kwiinkqubo ezilungele ngakumbi i-eco-friendly kulawulo lwenkunkuma, kubandakanywa ukurisayikilishwa kunye nokusetyenziswa kwakhona kodaka kwezolimo kunye nokujonga umhlaba, ukuqhubela phambili ukukhula kwemarike.
Imimiselo kunye nemigangatho ebekwe ngurhulumente wesigqeba malunga nolawulo lwe-sludge, kuye kwakho imfuno ekhulayo yeenkonzo zolawulo lwe-sludge. I-Arhente yoKhuseleko lokusiNgqongileyo (EPA) imisele imigangatho engqongqo yokulawulwa kodaka, kwaye imimiselo emininzi iphinde yapasiswa ngurhulumente ukubeka iliso nokukhuthaza iindlela ezisebenzayo zokulawula udaka.
Umzekelo, iBipartisan Infrastructure Legislation (i-BIL) ijolise ekuxhaseni uqoqosho lwasekhaya kunye nokunyusa amalinge akhoyo eziseko ezingundoqo akhoyo ukujongana nesidingo seziseko zokucocwa kwamanzi amdaka kwimimandla yelizwe.
Ukufudukela kwabantu ezidolophini okuqhubekayo nako kukhokelela ekwenyukeni kwemfuno yolawulo lwamanzi amdaka. Kwiindawo ezinabantu abaninzi, ukulahlwa ngokungafanelekanga kodaka kunokukhokelela kwiingozi ezinkulu zempilo, kuquka ukusasazeka kwezifo. Njengoko inani elikhulu labantu lihlala kwiindawo ezixineneyo, imfuneko yokucocwa okusebenzayo kwamanzi amdaka iba yeyona nto ibalulekileyo. Ulawulo olusebenzayo lwe-sludge luqinisekisa ukulahlwa okukhuselekileyo okanye ukusetyenziswa kwakhona kodaka, ngaloo ndlela ikhusela impilo yoluntu.
Ngokusekwe kudidi, icandelo lemisebenzi yonyango ephantsi koluntu (POTW) likhokele kwimarike ngesona sabelo sikhulu sengeniso esiyi-75.7% ngo-2023. Le misebenzi iyilelwe ukunyanga ilindle lasekhaya. Baqokelela amanzi amdaka kwimithombo eyahlukeneyo kwaye babandakanya naziphi na izixhobo kunye neenkqubo ezisetyenziselwa ugcino, unyango, kunye nokulahlwa kwamanzi amdaka kamasipala okanye kwimizi-mveliso kunye nodaka.
Icandelo lezixhobo ezikwisiza kulindeleke ukuba linikele ubungqina ngeyona CAGR ikhawulezayo kulo nyaka uqikelelwayo, ngenxa yokwabiwa kweenkqubo zokucocwa kwamanzi amdaka. Ukwanda kwabemi belizwe kunye nokuqhubekeka kwabantu basezidolophini kuphembelela imfuno yezisombululo zasekhaya zokuphatha udaka kunye nokucocwa kwamanzi, eziluncedo nezingabizi kakhulu.
Ngokusekwe kumthombo, icandelo likamasipala likhokele imarike ngesona sabelo sikhulu sengeniso ye-51.70% ngo-2023. Enye yezona zinto ziqhuba icandelo likamasipala kukunyuka kwemfuno yeenkonzo zokucocwa kwamanzi amdaka kwimimandla yasezidolophini. Njengoko izixeko zisanda neminyaka yeziseko ezingundoqo, kukho imfuneko enkulu yokucocwa kwamanzi amdaka okusebenzayo ukukhusela impilo yoluntu kunye nokusingqongileyo
Icandelo lemizi mveliso kulindeleke ukuba linikele ubungqina kweyona CAGR ikhawulezayo ngexesha loqikelelo, njengoko imizi-mveliso isanda kutyalwa imali kulawulo lodaka oluphucukileyo kunye nobuchwephesha bokukhupha amanzi ukuphucula ukusebenza kakuhle kunye nokunciphisa iimpembelelo zokusingqongileyo kunye nokuhlola amathuba okusetyenziswa kwakhona okunenzuzo kunye nokubuyiswa kobutyebi kubudaka.
