I-San Andreas Sanitary District Waste Water Treatment Plant ithole uxhaso lwemali ukuze kwenziwe ukuthuthukiswa okudingekayo kulesi sikhungo kanye ne-digester yaso eneminyaka engu-60 ubudala.
Umphathi wakwa-SASD u-Hugh Logan umi phambi komprosesa wemfucumfucu endaweni yokulawula imfucuza yesifunda.
I-San Andreas Sanitary District Waste Water Treatment Plant ithole uxhaso lwemali ukuze kwenziwe ukuthuthukiswa okudingekayo kulesi sikhungo kanye ne-digester yaso eneminyaka engu-60 ubudala.
Umphathi wakwa-SASD u-Hugh Logan umi phambi komprosesa wemfucumfucu endaweni yokulawula imfucuza yesifunda.
Ukwakhiwa kochungechunge lokuthuthukiswa kwengqalasizinda kuyaqhubeka e-San Andreas Sanitary District (SASD) Indawo Yokuhlanza Amanzi Angcolile e-San Andreas.
"Sinesikhungo sokwelapha esidala, futhi izinto eziningi ezisetshenziswayo zisekupheleni kokusebenza kwayo," kusho uHugh Logan, umphathi wesifunda, esizeni ngeledlule.
Lo mklamo ongu-$6.5 million uxhaswe ngezibonelelo ezivela ku-State Revolving Fund kanye noMnyango Wezolimo wase-US (i-USDA).Leso sabelomali sihlanganisa izindleko zokuhlela, ukuklama, ukuthengwa kwempahla, ukubuyekezwa kwemvelo nokwakha.
"Ukuthola imali yesibonelelo sikahulumeni kwakubalulekile ukuze isifunda sikwazi ukukhokhela lo msebenzi, sibe sigcina amanani endle efanelekile," kusho uTerry Strange, umongameli webhodi le-SASD.Uhlaka olusha lwamanani lwamukelwa ngo-2016, futhi ukukhuphuka kwamanani angu-1.87% kwagunyazwa ngoJulayi 1, 2019, ukuze kuhambisane nokwehla kwamandla emali, kusho uLogan.
"Ifilosofi evela ebhodini labaqondisi iwukuthi siphishekela ngentshiseko izibonelelo kanye nezikweletu ezinenzalo ephansi ukuze sigcine amazinga endle ephansi ngangokunokwenzeka," kusho u-Logan.
Okunye okubaluleke kakhulu ukuthuthukiswa ukushintshwa kwe-anaerobic digester eneminyaka engu-60 ubudala, ithangi elikhulu eliyicylindrical elicubungula udoti oqinile, noma ama-biosolids.
Wakhelwe ekuqaleni kweminyaka yawo-1950 ukuze uthole izakhamuzi ezincane, umshini awusemkhulu ngokwanele ukwelapha nokucubungula izinto eziqinile ezikhiqizwa kulesi sikhungo, kusho uLogan.Njengamanje isifunda sihlinzeka ngamanzi angcolile kumakhasimende angaphezu kuka-900 okuhlala nawokuhweba.Phezu kokukhula kwesibalo sabantu kusukela ngo-1952, ukuthuthukiswa okugunyazwe nguhulumeni ukusiza ukususa i-ammonia emanzini ngo-2009 kwengeze imfucuza eyengeziwe ukuze umshini wokugaya ugaye.
“Asikwazi ukuthola ukukhiqizwa nokwelashwa okwanele ngaleyo digester, okusho ukuthi iyanuka kancane futhi ayiphathwa ngendlela efanele,” kusho uLogan.“Esinye sezizathu esenze sakwazi ukuthola imali yesibonelelo sikahulumeni ukuthi sikhombisile ukuthi ayisindala nje, indala futhi ayisebenzi.”
ULogan wafanisa ukugaya ukudla nesimiso somuntu sokugaya: “Kuthanda ukuba kuma-degree angu-98;ithanda ukuphakelwa njalo futhi ixutshwe kahle.Izokhiqiza igesi, izinto eziqinile neziwuketshezi.Njengesisu somuntu, uma udla kakhulu, ukugaya kungaphatheka kabi.I-digester yethu iyaphatheka kabi ngoba asikwazi ukuyigcina emazingeni okushisa afanele ngoba sinemishini endala ngempela.Kufanele siyiphakele kakhulu ukuze ingabi naso isikhathi sokugayeka kahle, futhi ayixutshwa nhlobo, ngakho-ke i-byproduct ayiwona umkhiqizo omuhle.”
Ngokushintshwa, i-aerobic digester, ngeke kube khona ukukhishwa kwe-methane, futhi izokwazi ukuphatha imfucuza eqinile kakhulu ngesivinini esisheshayo.Izitshalo ezinkulu zingakwazi ukubuyisela i-methane ohlelweni lokugaya futhi ziyisebenzisele ukukhiqiza ugesi, kodwa i-SASD ayikhiqizi igesi eyanele ukuze kuthethelelwe ukuthenga ijeneretha, kusho u-Logan.
Ukugaya kwe-Aerobic kuyinqubo yezinto eziphilayo eyenzeka lapho kukhona umoya-mpilo, kusho u-Logan.Izifutha zikagesi ezinkulu zibhubhula umoya oketshezini olusesigayweni esifakwe ukhonkolo ukuze sisize ukuzinzisa udoti oqinile kanye nokunciphisa inkathazo (iphunga, amagundane), izifo kanye nesamba semfucuza esidinga ukulahlwa.
“Ubuchwepheshe obusha buzovikeleka;akukho kukhiqizwa kwegesi, ukwelashwa okulula, ”kusho u-Logan, elunguza onqenqemeni lwembobo ezoba yisitsha sokugaya ukudla."Kunezindleko eziphakeme zamandla okufaka umoya, kodwa umsebenzi omncane futhi uyingozi encane, ngakho-ke kumayelana nokugeza ekugcineni."
Okunye ukuthuthukiswa okuxhaswe yisibonelelo sikahulumeni kuhlanganisa ukuthuthukiswa kwesistimu kagesi yefekthri kanye nokufakwa kohlelo olusha lokulawula kanye nokutholwa kwedatha yokulawula inqubo nokuphepha.
Ukwengeza, amachibi okugcina amanzi angcolile aye ahlanzwa ukuze kuvikelwe amanzi ekugugulekeni futhi anikeze umthamo omkhulu wokugcina amanzi ngezikhathi zemvula enkulu.
Ngemva kokuba izigaba ezihlukahlukene zokwelashwa seziqediwe embonini, amanzi akhishwa epayipini elingamakhilomitha ubude ukuya eNorth Fork yoMfula iCalaveras lapho amanzi egeleza emfuleni ukuze ahlanjululwe, noma efafazwa ngezifafazi ukuze afakwe umhlabathi.
Osonkontileka bakwa-WM Lyles kanye nethimba le-KASL Construction Management bakhethwa ukuze baqedele umsebenzi wokuthuthukisa, futhi ukwakhiwa kulindeleke ukuthi kuqedwe entwasahlobo ka-2020.
“Inhloso yethu wukuqeda le phrojekthi ngesikhathi, ngesabelomali, nangezinga eliphezulu lokuphepha nekhwalithi yesifunda,” kusho uJack Scroggs, umphathi wezokwakha esifundeni.
U-Logan uthe i-SASD iphinde ifune u-$750,000 woxhasomali ukuze kwakhiwe isiteshi esisha futhi kushintshwe isikrini ku-headworks, isethi yokuqala yezinqubo zokuhlunga amanzi angcolile angena esikhungweni adlula kuwo.
Iphinde ifune uxhaso lokubuyisela isihlungi esigelezayo, umbhoshongo oneminyaka engu-50 wamapulasitiki anothayela odiliza imfucuza nge-slime yebhaktheriya.
“Ngokutshala imali engqalasizinda yalesi sikhungo, sinamandla okwenza lokho okufunwa umphakathi,” kusho uLogan.“Uma umphakathi noma isifunda sinezinhlelo abafuna ukuzenza, kuwumsebenzi wethu endaweni yokugcina amanzi angcolile ukugcina ingqalasizinda ikulungele ukutholwa.Le phrojekthi ngokuqinisekile iyasiza kulokho.Kuyisinyathelo esiyisisekelo sokuthi noma yimuphi umphakathi ube nengqalasizinda ukuze uthole amanzi ahlanzekile kanye nokuhlanzwa kwamanzi angcolile.”
UDavis uphothule e-UC Santa Cruz eneziqu ze-Environmental Studies.Ukhuluma ngezindaba zemvelo, ezolimo, umlilo kanye nohulumeni wasekhaya.U-Davis uchitha isikhathi sakhe samahhala edlala isiginci futhi agibele izintaba nenja yakhe, uPenny.
Izibuyekezo ezihlokweni zakamuva ze-Calaveras Enterprise kanye ne-Sierra Lodestar kanye nezibuyekezo zezindaba ezihamba phambili
