Izaqhwithi zelanga ze-G5 kunye nokusinda kwigridi yombane kukucima¶

I-geomagnetic superstorm imele enye yezona ngozi zinzima zendalo ezijongene nempucuko yetekhnoloji yanamhlanje. Xa ummandla welanga osebenzayo ukhupha i-Coronal Mass Ejection enkulu, eyaziwa ngokuba yi-CME, iibhiliyoni zeetoni zeplasma yelanga enemagnethi zigqabhuka ziye emajukujukwini ngesantya esidlula iikhilomitha ezingama-2,000 ngesekhondi (1,240 yeemayile ngomzuzwana). Ukuba indawo enemagnethi edibeneyo yemagnethi ikhomba emazantsi, inxibelelana ngokuthe ngqo ne-geomagnetic field. Olu qhagamshelo lubangela uqhagamshelo olunogonyamelo lwemagnethi, luqhuba amakhulu amawaka ee-amperes ezibangelwa yi-geomagnetic currents ngokusebenzisa iigridi zamandla, luzalise iziguquli zothumelo lombane ophezulu, kwaye lugrogrisa ngokudilika iigridi zombane zengingqi kangangeenyanga.

Ngokungafaniyo neengozi eziqala ngokukhawuleza ezinjengeenyikima okanye iinkanyamba, imozulu yendawo ilandela amaxesha ahlukeneyo okuqhubela phambili ngokomzimba. Iindawo zokuphonononga zesathelayithi ezimi kwi-Sun-Earth Lagrange Point 1 zibonelela phakathi kwe-15 kunye ne-48 yeeyure zesaziso kwangethuba phambi kokuba ilifu elikhulu leplasma lingqubane nemagnetosphere yethu. Ukuthabatha inyathelo eliqinisekileyo ngeli xesha lesilumkiso kuvumela amakhaya, abaqhubi bakamasipala, kunye nezixhobo zokukhusela izixhobo ezibalulekileyo, ukugcina amanzi acocekileyo, ukhuseleko lwemithombo yombane engenye, nokulungiselela ixesha elide ngaphandle kombane kamasipala, amanzi asele esebenza, okanye unxibelelwano ngeselula.

Physics of Coronal Mass Ejections and Solar Superstorms¶

A coronal mass ejection represents an immense bubble of magnetized solar plasma composed of ionized hydrogen protons, alpha particles, and free electrons. These plasma ejections originate from areas of twisted magnetic fields known as active solar regions or sunspots. When opposite magnetic field lines within these active regions shear and reconnect, an explosive release of stored energy occurs. This process propels billions of tons of solar material into space at velocities ranging from 400 kilometers per second (250 miles per second) during minor events to over 2,500 kilometers per second (1,550 miles per second) during superstorms.

As this plasma travels across interplanetary space, it compresses the ambient solar wind into a dense shock front. The orientation of this magnetic field along the north-south axis, defined as the Bz component, dictates ground consequences. When the field points northward, parallel to Earth's dipole, the magnetopause deflects the particle cloud safely around the planet.

Xa icandelo le-Bz lijikela ngamandla emazantsi, i-antiparallel kwimigca yamandla oMhlaba, uqhagamshelo lwemagnethi lwenzeka ecaleni kwemini yemagnetopause. Oku kudityaniswa kwakhona kuvula umjelo womzimba wamandla omoya welanga ukuze utofe ngokuthe ngqo kwimagnetosphere yangaphakathi. I-plasma engenayo ikhawuleza kwimigca yebala ukuya kwimimandla ye-polar, iqhuba i-auroral electrojet currents kwi-ionosphere kwindawo ephakamileyo phakathi kweekhilomitha ezili-100 kunye ne-150 yeekhilomitha (iikhilomitha ezingama-62 kunye neekhilomitha ezingama-93).

Iimpembelelo zemozulu emajukujukwini zibonakala kwizigaba ezithathu ezahlukileyo zexeshana kulandela ugqabhuko-dubulo olukhulu lwelanga:

• I-Electromagnetic Radiation Shock (Ifika ngemizuzu eyi-8.3): Ukuhamba ngesantya sokukhanya, ukukhanya kwe-ultraviolet kunye nee-X-reyi zigqobhoza kwi-ionosphere yasemini. Le mitha yemitha ihluba ii-elekhtroni kwiimolekyuli ze-atmospheric, ibangele ukucima kukanomathotholo ngoko nangoko kuwo wonke amabhanti e-frequency ephezulu phakathi kwe-3 megahertz kunye ne-30 megahertz.
• Isaqhwithi soMtha weSola (Ifika kwimizuzu engama-20 ukuya kwiiyure ezininzi): Iiprotons ezihambelanayo kunye neeyoni ezinzima zihamba ngemigca yebala ukuya ngqo kwi-atmospheres yesibanzi esiphezulu. La masuntswana abangela ukuphazamiseka kwesiganeko esinye kwiisathelayithi ze-orbital, zonakalise ulungelelwaniso lwelanga, kwaye aveze iinqwelomoya ezidlulayo kwiidosi eziphakamileyo zemitha.
• I-Geomagnetic Storm Shock Front (Ifika kwiiyure ezili-15 ukuya kwezingama-48): Ilifu leplasma lifikelela eMhlabeni, licinezela imagnetopause yasemini ngaphakathi ukusuka kwi-10 Earth radii ukuya ngaphantsi kwe-4 Earth radii. Iziphumo zokuguquguquka kwehlabathi jikelele kummandla we-geomagnetic kuvelisa imisinga yombane emikhulu kwiziseko ezingundoqo zomhlaba.

I-Space Weather Prediction kunye ne-NOAA Scales¶

Iziko leSizwe lokuQikelela iMozulu yeNdawo yoLwandle kunye ne-Atmospheric libeka ngokweendidi imozulu emajukujukwini kusetyenziswa izikali ezithathu ezisemgangathweni ezinemigangatho emihlanu. Ezi zikali zichaza i-Geomagnetic Storms, iSolar Radiation Storms, kunye neRadio Blackouts. Ii-arhente zamaqabane eziquka i-Arhente ye-European Space kunye ne-UK Met Office zabelana ngolu hlelo lusemgangathweni.

The planetary K-index, quantified on a scale from 0 to 9, measures horizontal geomagnetic field disturbances over three-hour intervals using ground magnetometers. For extreme G5 events, scientists measure the disturbance storm-time index, known as Dst, tracking equatorial ring current strength in nanoteslas. While moderate storms reach Dst values of negative 50 nanoteslas to negative 100 nanoteslas, extreme superstorms exceed negative 500 nanoteslas, with the 1859 Carrington Event estimated between negative 850 nanoteslas and negative 1,000 nanoteslas.

Space weather agencies also monitor solar radiation storms across the S1 to S5 spectrum based on flux levels of energetic protons exceeding 10 megaelectronvolts. Radiation levels at the S5 threshold present biological hazards to astronauts outside shielding and induce complete radio absorption throughout both polar caps. Radio blackouts, categorized from R1 to R5, track peak solar X-ray flux, where an R5 extreme blackout causes complete high-frequency communication blackout across the sunlit hemisphere.

Geomagnetically Induced Currents and Transformer Physics¶

Indlela ebonakalayo edibanisa izaqhwithi ze-geomagnetic eziphezulu kwi-atmospheric kunye nokusilela kweziseko ezingundoqo zomhlaba zisekelwe kumthetho we-Faraday wokufakwa. Ukwahluka okukhawulezayo kumhlaba wemagnethi weplanethi kukhuthaza iindawo zombane zengingqi ngaphakathi koqweqwe oluqhubayo kunye nengubo yoMhlaba. Le mimandla ye-geoelectric ethe tyaba, elinganiswa ngeevolthi ngekhilomitha, iqhuba imisinga yombane ngeesekethe zokuqhuba ezivaliweyo eziqhagamshelana nomhlaba kwiindawo ezininzi. Ngenxa yokuba uthungelwano lwamandla elizwekazi, imibhobho, kunye neentambo ezingaphantsi kolwandle zithatha amakhulu eekhilomitha, zisebenza njengee-eriyali zokuqokelela le misinga.

Imisinga eyenziwe nge-geomagnetic, edla ngokufinyezwa njenge-GIC, isebenza kwii-ultra-low frequencies phakathi kwe-0.001 hertz kunye ne-0.1 hertz. Kwizixhobo ze-voltage eziphezulu ezenzelwe ukutshintshwa kwangoku kwi-50 hertz okanye i-60 hertz, le misinga iziphatha njengombane othe ngqo. Xa i-geomagnetically induced current ingena kwi-substation ephantsi, ihamba ngoqhagamshelo olungathathi hlangothi ngokuthe ngqo kwii-winding zobhedu ze-extra-high-voltage transformers.

Ngaphantsi kokusebenza okuqhelekileyo, i-transformer core isebenza ngokulinganayo ngaphakathi kwimida yoyilo lwemagnethi, ukuhamba ngebhayisikile phakathi kwemagnethi elungileyo kunye nengalunganga ngaphandle kokugqithisa imida yokuzalisa. Xa umbane othe ngqo ovela kwisaqhwithi se-geomagnetic ungena kwii-windings, useka i-unidirectional unidirectional magnetic bias. Olu tshintsho lubangela ukuba undoqo ugcwale ngozibuthe ngexesha lesiqingatha somjikelo ngamnye otshintshayo, into eyaziwa ngokuba kukuzaliseka kwesiqingatha somjikelo.

Ukuzaliswa kwesiqingatha somjikelo kubangela iingxaki ezinzima zokusebenza:

• I-Sky Magnetic Flux kunye neTanki Overheating: Wakuba undoqo wentsimbi ugcwele, ukuguquguquka okutshintshisayo kuphalala kumalungu olwakhiwo, kubandakanywa iipleyiti zeqhina kunye netanki yentsimbi. La macandelo amava eeddy currents zasekhaya, ezibangela ukuba amaqondo obushushu angaphakathi anyuke ngaphezu kwama-200 degrees celcius (392 degrees Fahrenheit) kwimizuzu nje embalwa.
• I-Insulating Oil Breakdown and Gas Generation: Amaqondo obushushu aphezulu abolisa i-oyile ekhuselayo kunye nokufakwa kwe-cellulose. Oku kuvelisa iigesi ezinokutsha, kubandakanywa i-hydrogen kunye ne-methane, ebangela ukuhanjiswa koxinzelelo lwe-Buchholz kunye nomngcipheko wokugqabhuka kwetanki.
• Imfuno ePhakamileyo yaMandla aSebenzayo: Isiguquli esigcweleyo sisebenzisa ukuya kutsho kumashumi amabini amandla ayo aqhelekileyo asebenzayo. Xa uninzi lweziguquli zigcwala ngaxeshanye, intsilelo esebenzayo ibangela ukuhla kwamandla ombane kwingingqi.
• ** IsiZukulwana seHarmonic kunye ne-Relay Misoperation: ** Ii-cores ezigcweleyo zigqwetha i-alternating-current waveform, ivelisa i-harmonics enzima. Le misinga ye-harmonic ibangela ukuba iireyidi ezikhuselayo zihambe imigca esempilweni kunye neeyunithi zejeneretha ngaphandle kweintanethi.

Ijoloji yommandla imisela ukuba sesichengeni komhlaba. Imimandla ethotywe ngomgangatho wamandulo wekristale, njengeCanadian Shield, ukwakheka kwePiedmont, kunye neScandinavia Shield, ibonisa ukumelana nombane okuphezulu. Kwezi ndawo, imisinga igxila phezulu ngokusebenzisa iindlela zokumisa eziphantsi ezibonelelwa zizikhululo. Izitya ezinzulu zentlenga zinika ukuxhathisa okuphantsi komhlaba, ukunciphisa i-GIC ingena kwiigridi zothumelo olungaphezulu.

Ubumnyama belizwekazi kunye ne-Cascading Grid Collapse¶

Isoyikiso esibangelwe sisiphango seCarrington-class geomagnetic sahluka ngokusisiseko kukuphazamiseka kwemozulu yasekhaya okubangelwa ziinkanyamba okanye izaqhwithi zomkhenkce. Ngelixa izehlo zemozulu eziqatha zisonakalisa iipali zasekhaya kunye neengcingo ezinokulungiswa ngeentsuku ngabasebenzi abancedisana, i-geomagnetic superstorm ihlasela i-high-high-voltage bulk transmission supergrid ngaxeshanye kwizikali zelizwekazi.

Ukuba sesichengeni kweenkqubo zala maxesha zamandla kubangelwa kuqhagamshelo olusebenzayo kunye nekhonkco lobonelelo oluethe-ethe olulawula inyathelo lokunyuka kombane ongaphezulu kunye neenguqu ezizenzekelayo. Ezi yunithi zikhulu, zisebenza kumbane ophakathi kwama-230 neekhilovolti ezingama-765, zinobunzima obuphakathi kwe-100 yeetoni zemetric kunye ne-400 yeetoni zemetriki (i-110 yeetoni zase-US kunye ne-440 yeetoni zase-US) kwaye zenziwe ngobunjineli obukhethekileyo kwizitishi ezincinci ezithile.

Phantsi kwesehlo semozulu esigqithileyo se-G5, amakhulukhulu eenguqu zevoltage ezongezelelweyo kunxibelelwano oluninzi lujongana nobushushu obugqithileyo obungundoqo, umonakalo osisigxina, kunye nokusilela ukujikajika. Amandla okuvelisa i-Global kwi-transformer yamandla amakhulu athintelwa kukufikelela okulinganiselweyo kwintsimbi yombane kunye nezixhobo zokujija. Amaxesha okukhokela ekufumaneni isiguquli esinye esitshintshiweyo esinevoltage ephezulu aqhele ukunwenwa phakathi kweenyanga ezili-18 kunye neenyanga ezingama-36. Ukuba uninzi lweeyunithi ezibalulekileyo zonakaliswa ngaxeshanye, iigridi zothumelo lwengingqi zijongana namaxesha okubuyisela iminyaka emininzi.

Ukunika amandla kwakhona igridi yombane emva kokuwa okuxhaphakileyo kuxhomekeke kwiiyunithi ezikhethekileyo zokuvelisa ezikwaziyo ukuqalisa ngaphandle kwamandla angaphandle, ezifana nezityalo ezizinikeleyo zombane. Iinkqubo zokuqalisa ezimnyama zifuna ulungelelwaniso oluchanekileyo lwamandla okwenene kunye nasebenzayo njengoko imigca inikwa amandla amacandelo ngecandelo.

Ukuvuka kwesaqhwithi se-geomagnetic, abaqhubi begridi bajongana nezithintelo ezinzima zokuqala ezimnyama:

• Ilahleko yoNxibelelwano: Iiyunithi zetheminali ezikude zifuna unxibelelwano oluqhubekayo. Xa iibhetri zogcino kwi-repeaters ziphelelwa, i-dispatchers ilahlekelwa ukubonakala kwizikhundla ze-breaker.
• I-Harmonic Resonance: Imigca emide eyomelezayo ivelisa amandla asebenzayo, amandla ombane okuqhuba aphezulu kwaye ibangela izandi eziyonakalisayo.
• Iibhetri Zolawulo Eziphelelweyo: Iindlela zohambo lokuqhawula isekethe zixhomekeke kwiibhanki ezisebenza ngokuthe ngqo, ezigcina amandla olawulo iiyure ezisi-8 ukuya kwezili-12 kuphela ngexesha lokucima.
• Izaqhwithi zeSibini: Izaqhwithi zeGeomagnetic zibonisa izaqhwithi ezilandelelanayo ezithatha iiyure ezingama-24 ukuya kwezingama-72, zibeka emngciphekweni wohambo oluphinda-phindiweyo kwizixhobo ezisanda kufakwa amandla.

Uthungelwano ngoMnxeba, i-GNSS Scintillation, kunye neZiseko zoMbhobho¶

Ngaphaya kwegridi yothumelo lombane, imozulu yendawo egqithisileyo ithoba isixokelelwano sesathelayithi, usasazo lukanomathotholo, kunye nothungelwano lwemibhobho engaphantsi komhlaba. Ukuqonda obu buthathaka beziseko ezingundoqo kubalulekile ukugcina ukhuseleko lomntu kunye nolwazi lwemeko.

I-Global Navigation Satellite Systems, equka i-United States Global Positioning System, i-European Galileo network, i-Russian GLONASS, kunye ne-Chinese BeiDou, zixhomekeke kwimiqondiso yerediyo esasazwa ukusuka kwi-orbit yoMhlaba ephakathi kumphakamo omalunga neekhilomitha ezingama-20,000 (iikhilomitha ezili-12,420). Njengoko ezi zibonakaliso zihamba nge-ionosphere ephazamisekileyo, zidibana nezakhiwo ze-plasma eziphazamisayo ezibonakaliswe ngeegradient ezibukhali kwiTotal Electron Content. Ezi zitenxo zeplasma zibangela ukuguquguquka okukhawulezayo kwi-amplitude yesignali kunye nesigaba, into ebizwa ngokuba yi-ionospheric scintillation.

Ngexesha le-G5 superstorm, i-scintillation enzima ibangela ukuba abamkeli be-GPS emhlabeni kwaye kwinqwelo-moya yorhwebo baphulukane nesitshixo sokuthwala ngokupheleleyo. Izisombululo zokubeka izikhundla zikhukuliseka ngamakhulu eemitha okanye uyeke ngaphandle kweintanethi ngokupheleleyo kangangeentsuku. Iimpawu zexesha ezichanekileyo ezithathwe kwi-GPS azithembeki okanye azifumaneki, ukunyanzelisa iinkqubo ezibalulekileyo kwiindlela ezibolileyo ze-crystal oscillator holdover zangaphakathi.

Isiseko sesathelayithi kumjikelo ophantsi woMhlaba sijongene nokuwohloka okumandla kwe-orbital. Imitha yelanga egqithisileyo ye-ultraviolet kunye ne-geomagnetic particle precipitation itshisa i-atmosfera engaphezulu, ibangela ukuba i-thermosphere yande iye ngaphandle esithubeni. Uxinaniso lweatmospheri ephakathi kumphakamo ophakathi kwama-300 eekhilomitha kunye nama-800 eekhilomitha (186 yeemayile kunye nama-497 eemayile) lonyuka ngezinto ezimbini ukuya kwezilishumi. Oku kunyuka koxinano ngesiquphe kudala ukutsalwa okuphezulu kwe-aerodynamic kwiisathelayithi ezijikelezayo, kuhlutha amandla e-orbital kunye nokuguqula iitrajectories zesiphekepheke.

I-hydrocarbon yentsimbi engaphantsi komhlaba kunye nemibhobho yamanzi ifumana ukuthotywa okukhulu ngenxa yemisinga ye-telluric. Imibhobho ineengubo zokhuselo ze-dielectric kunye ne-cathodic rectifiers yokukhusela ukuthintela ukubola. Imisinga ye-teluric eyenziwe nge-geomagnetic iqukuqela kudonga lombhobho wentsimbi onganyangekiyo ifuna iindawo zokukhupha umhlaba. Le misinga iqhuba izinto ezinokubakho zemibhobho ukuya emhlabeni kude ngaphandle kweefestile ezikhuselekileyo ezikhuselayo, zibangela ukuthotywa kwemingxuma ekhawulezileyo kunye neengozi zombane.

Izehlo zeMbali zeGeomagnetic kunye nokuba sesichengeni kwangoku¶

Izehlo zemozulu zembali ezibhaliweyo zibonelela ngemilinganiselo enentsingiselo yokuvavanya ukuba sesichengeni kwethekhinoloji yale mihla kunye nokuqonda ubungakanani obubonakalayo bezaqhwithi ezigqithisileyo zelanga.

Owona mgangatho uphambili wezaqhwithi zelanga siSiyunguma saseCarrington sikaSeptemba 1 ukuya kuSeptemba 2, 1859, ethiywe ngesazi ngeenkwenkwezi saseBhritane uRichard Carrington, owabona idangatye eliqaqambileyo elimhlophe elidubula ngaphezu kweqela elikhulu lelanga. Isiphumo sokukhutshwa kwe-Coronal mass ejection kuhambe i-150 yezigidi zeekhilomitha (93 million miles) ukuya eMhlabeni ngeeyure ezimangalisayo eziyi-17.6, ebonisa i-avareji yesantya sokuhamba esidlula iikhilomitha ezingama-2,300 ngesekhondi (1,430 yeemayile ngomzuzwana). Isaqhwithi se-geomagnetic savelisa imiboniso eqaqambileyo kangangokuba abembi begolide kwiiNtaba zeRocky baqalisa ukulungiselela isidlo sakusasa ezinzulwini zobusuku, ngoxa i-auroras yabonwa kwiindawo ezishushu eColombia, eHawaii nasePanama.

Uthungelwano lwetelegraph yehlabathi lonke lufumene ukuwohloka ngokupheleleyo kokusebenza. Imisinga yomhlaba eyonyanzeliswayo ihlawulise imigca yetelegraph ukuya kumakhulu eevolthi, inika abasebenzi bombane, iingcingo ezinyibilikayo, kunye neteyiphu yephepha elivuthayo. Kwiimeko ezininzi, abaqhubi baqhawula iibhetri ngokupheleleyo baze bathumele imiyalezo eqhutywa kuphela yimisinga yasemhlabeni eyenziwe nge-geomagnetic.

NgoMeyi 1921, iNew York Railroad Storm yantlitha ihlabathi eliya lizaliswe ngumbane. Imisinga eyenziwe nge-geomagnetic yangena kumqondiso osisiseko kunye neenkqubo zamandla zoMzila kaloliwe oMbindi waseNew York, zivutha umlilo kwinqaba yolawulo yaseManhattan kunye nokukhubaza imiqondiso kuthungelwano lukaloliwe. I-telegraph yehlabathi jikelele kunye ne-subsea cable systems ziye zafumana imililo, kunye neefowuni zokutshintsha iibhodi ezivuthayo ezivela kwi-telluric currents.

Ukuba semngciphekweni kweegridi zangoku ezitshintshisanayo kwaboniswa ngoMatshi 13, 1989, ngexesha lokucima kukagesi kweHydro-Québec. Ukukhutshwa okukhulu kwe-coronal mass ejection kubangele isaqhwithi se-G5 esibangele imisinga ngqo kwi-Canadian Shield. Kwimizuzwana engama-92, ababuyekezi be-var abasixhenxe abangatshintshiyo kuthungelwano lwe-735-kilovolt bakhubeke ngaphandle kwe-intanethi ngenxa yokugqwetheka kwe-harmonic kunye ne-transformer saturation. Ngenxa yokuvinjwa ukulawulwa kwamandla ombane, yonke igridi yamandla ephondo iye yawa, yafaka abantu abazizigidi ezithandathu kubumnyama obuqhaqhazelisa amazinyo kangangeeyure ezilithoba.

Kutshanje, i-Halloween Storms ka-2003 yaqalisa ukucima komnyama eMalmö, eSweden, yaza yavala iNkqubo ye-FAA Wide Area Augmentation System kangangeeyure ezingama-30. NgoMeyi ka-2024, isaqhwithi se-G5 yoSuku loMama saqhubela imiboniso ye-auroral kuyo yonke imimandla yobubanzi obuphakathi kwihlabathi jikelele, sabangela ukukhukuliseka kwezixhobo zezolimo ezichanekileyo, kwaye safuna ukuthomalaliswa okungaqhelekanga ngabaqhubi bothumelo ukunqanda ukonakala kwesiguquli.

Ukuwa kweNkqubo yaManzi kaMasipala kunye nokusinda kweMpilo kaRhulumente¶

Isiphumo esikhawulezileyo sendawo ebanzi, ixesha elide lokuwa kwegridi yombane kukungaphumeleli okukhawulezileyo kokucocwa kwamanzi kamasipala kunye nokuhanjiswa kothungelwano. Ngelixa abemi abaninzi becwangcisela ukukhanyisa kunye nokugcinwa kokutya, inkqubo yefiziksi yamanzi iyalela ukuba ukusinda komntu kuxhomekeke ekuthinjweni kwamanzi kwangoko kunye nolawulo olungqongqo lwezococeko.

Uthungelwano lokuhanjiswa kwamanzi kamasipala luxhomekeke kwiimpompo zombane ezinomthamo ophezulu wokuphakamisa amanzi ukusuka kwi-aquifer, emilanjeni, okanye kwimithombo yamanzi ukuya kwindawo yokucoca, ukuwanyanzela ngeebhedi zokuhluza iikhemikhali, kunye nokuwatofa kwiindlela zokuhambisa ezicinezelekileyo. Ngelixa amatanki okugcina ukutya okuxhuzula okuphakamileyo agcina uxinzelelo losasazo ngexesha lokumka kombane okwesiqhelo okwexeshana elifutshane, amaziko ogcino kamasipala abamba kuphela umthamo owaneleyo wokwanelisa iiyure ezili-12 ukuya kwezingama-24 zosetyenziso lwesiqhelo lwendawo yokuhlala.

Emva kokuba uxinzelelo lomgca wokusabalalisa lwehla ngaphantsi kwe-140 kilopascals (iipounds ezingama-20 nge-intshi nganye yesikwere), iisistim zamanzi zikamasipala zingena kwimowudi yokungaphumeleli kokungcola eyaziwa ngokuba yi-negative pressure back-siphonage. Imibhobho yokuhambisa amanzi angaphantsi komhlaba isebenza kwimisele ekwabelwana ngayo ecaleni kwemibhobho kamasipala yogutyulo, imisele yokuqukuqela, kunye neetafile zamanzi aphantsi komhlaba angcolisekileyo.
