I-San Andreas District Sanitary Waste Water Treatment Plant ifumene isibonelelo-mali sokwenza uphuculo oluyimfuneko kwiziko kunye ne-digester yalo eneminyaka engama-60 ubudala.
UMphathi weSASD uHugh Logan ume phambi komprosesa wamanzi amdaka kwiziko lolawulo lwenkunkuma yesithili.
I-San Andreas District Sanitary Waste Water Treatment Plant ifumene isibonelelo-mali sokwenza uphuculo oluyimfuneko kwiziko kunye ne-digester yalo eneminyaka engama-60 ubudala.
UMphathi weSASD uHugh Logan ume phambi komprosesa wamanzi amdaka kwiziko lolawulo lwenkunkuma yesithili.
Ulwakhiwo kuthotho lophuculo lweziseko ezingundoqo luyaqhuba kwiSithili saseSan Andreas Sanitary (SASD) kwiZiko lokucoca amanzi amdaka eSan Andreas.
“Sineziko lonyango elidala, kwaye uninzi lwezixhobo zisekupheleni kobomi baso obuluncedo,” utshilo uHugh Logan, umphathi wesithili, kwindawo kwiveki ephelileyo.
Iprojekthi ye-6.5 yezigidi zeerandi ixhaswa ngenkxaso-mali evela kwi-State Revolving Fund kunye neSebe lezoLimo lase-US (USDA).Olo hlahlo lwabiwo-mali lubandakanya iindleko zokucwangcisa, ukuyila, ukuthenga, uphononongo lokusingqongileyo kunye nolwakhiwo.
“Ukufumana inkxaso-mali kwakubalulekile ukuze isithili sibenako ukufikelela kwiprojekthi, ngelixa sigcina amaxabiso ogutyulo afanelekileyo,” utshilo uTerry Strange, umongameli webhodi yeSASD.Ulwakhiwo olutsha lweereyithi lwamkelwa ngo-2016, kwaye ukunyuka kwesantya se-1.87% kwavunywa ngoJulayi 1, 2019, ukuhambisana nokunyuka kwamaxabiso, uLogan uthe.
"Ifilosofi evela kwibhodi yabalawuli kukuba siqhuba ngenkuthalo izibonelelo kunye neemali-mboleko ezinenzala ephantsi ukuze sigcine amazinga ogutyulo ephantsi kangangoko sinakho," utshilo uLogan.
Olona phuculo lubalulekileyo kukutshintshwa kwe-anaerobic digester eneminyaka engama-60 ubudala, itanki enkulu eyicylindrical eyenza inkunkuma eqinileyo, okanye i-biosolids.
Yakhelwe ekuqaleni kweminyaka yoo-1950 kubahlali abancinci, lo matshini awusekho mkhulu ngokwaneleyo ukunyanga kunye nokulungisa izinto eziqinileyo ezenziwe kwiziko, utshilo uLogan.Isithili sithetha nje sibonelela ngeenkonzo zamanzi amdaka kubathengi abangaphezu kwama-900 abahlala kunye nabezorhwebo.Ngaphezulu kokukhula koluntu ukusukela ngo-1952, uphuculo olugunyaziswe ngurhulumente ukunceda ukususa i-ammonia emanzini ngo-2009 yongeze inkunkuma eyongezelelekileyo ukuze isetyenzwe.
“Asinakukwazi ukufumana imveliso eyaneleyo kunye nonyango ngaloo digester, okuthetha ukuba iyanuka kancinci kwaye ayiphathwa kakuhle njengoko kufuneka,” utshilo uLogan.“Esinye sezizathu zokuba sakwazi ukufumana inkxaso-mali kukuba siye sabonisa ukuba ayindala nje, indala kwaye ayisebenzi.”
ULogan wafanisa inkqubo yokwetyisa nenkqubo yomntu yokwetyisa: “Ithanda ukuba kuma-98 degrees;iyathanda ukutyiswa rhoqo kwaye ixutywe kakuhle.Iza kuvelisa igesi, izinto eziqinileyo kunye nezilulwelo.Njengesisu somntu, ukuba utya kakhulu, i-digester inokuphazamiseka.I-digester yethu iyakhathazeka kuba asikwazi ukuyigcina ikwiqondo lobushushu elifanelekileyo kuba sinezixhobo ezindala ngokwenene.Kufuneka siyityisa kakhulu ukuze ingabi naxesha lokwetyisa kakuhle, kwaye ayixutywanga kwaphela, ngoko ke imveliso ayiyomveliso ilungileyo.”
Ngokutshintshwa, i-aerobic digester, ayiyi kubakho ukukhutshwa kwe-methane, kwaye iya kukwazi ukunyanga inkunkuma eqinile ngakumbi ngesantya esikhawulezayo.Iiplanti ezinkulu ziyakwazi ukubuyisela imethane kwinkqubo yokwetyisa kwaye ziyisebenzisele ukuvelisa umbane, kodwa i-SASD ayivelisi rhasi yaneleyo ukuthethelela ukuthenga ijenereyitha, utshilo uLogan.
I-Aerobic digestion yinkqubo yezinto eziphilayo eyenzeka phambi kweoksijini, utshilo uLogan.Izivutheli zombane ezinkulu zibhubhula umoya kulwelo olukwi-concrete-lined digester ukunceda ukuzinzisa inkunkuma eqinileyo kunye nokunciphisa inkathazo (amavumba, iimpuku), izifo kunye nobunzima bubonke benkunkuma efuna ukulahlwa.
“Ubugcisa obutsha buya kukhuseleka;akukho mveliso yerhasi, unyango olulula,” utshilo u-Logan, ejonge ngaphaya komngxuma wokuvala umngxuma oza kugcina idigester entsha."Kukho ixabiso eliphezulu lamandla okuhambisa umoya, kodwa umsebenzi omncinci kwaye unobungozi obuncinci, ngoko malunga nokuhlamba ekugqibeleni."
Olunye uphuculo oluxhaswa ngemali yinkxaso-mali lubandakanya ukuphuculwa kwenkqubo yombane yomzi-mveliso kunye nokufakelwa kolawulo olutsha lolawulo kunye nenkqubo yokufunyanwa kwedatha yolawulo lwenkqubo nokhuseleko.
Ukongeza, amadama okugcina amanzi amdaka acocwa ukuze kukhuselwe ukhukuliseko lwamachibi kwaye abonelele ngomthamo omkhulu wokugcina ngexesha lemvula enkulu.
Emva kokuba amanqanaba ahlukeneyo onyango kwiplanti egqityiwe, amanzi akhutshwa kumbhobho omde wemayile ukuya kwiFork yaseMantla yoMlambo iCalaveras xa amanzi equkuqela emlanjeni ukuze axutywe, okanye etshizwe ngezitshizi ukuze agalelwe umhlaba.
I-WM Lyles Contractors kunye neqela loLawulo loKwakha le-KASL baye bakhethwa ukuba bagqibezele iprojekthi yophuculo, kwaye ulwakhiwo kulindeleke ukuba lugqitywe ngentwasahlobo ka-2020.
“Injongo yethu kukugqibezela le projekthi ngexesha, ngohlahlo lwabiwo-mali, kunye nelona nqanaba liphezulu lokhuseleko nomgangatho wesithili,” utshilo uJack Scroggs, umanejala wokwakha wesithili.
U-Logan uthe i-SASD ikwafuna i-$750,000 yenkxaso-mali yenkxaso-mali yokwakha ijelo elitsha kunye nokubuyisela isikrini kwi-headworks, iseti yokuqala yeenkqubo zokucoca amanzi amdaka angena kwindawo adlula kuyo.
Ikwafuna inkxaso-mali yokubuyisela isihluzi esincincizayo, inqaba eneminyaka engama-50 ubudala yeeplastiki ezityabukileyo eziqhekeza inkunkuma nge-slime yebhaktiriya.
“Ngotyalo-mali kwiziseko zoncedo, sinamandla okuphumeza oko kufunwa luluntu,” utshilo uLogan.“Ukuba uluntu okanye idolophu inezicwangciso abafuna ukuyiphumeza, ngumsebenzi wethu kumzimveliso wamanzi amdaka ukugcina iziseko zophuhliso zilungele ukufunyanwa.Le projekthi ngokuqinisekileyo iyanceda kulo mba.Linyathelo elisisiseko kulo naliphi na uluntu ukuba libe neziseko eziluncedo zokucocwa kwamanzi acocekileyo nokucocwa kwamanzi amdaka.”
