1) Ngokwendawo yokuphuma kwamanzi, kukho iintlobo ezintathu eziphambili: ishawari ephezulu yokutshiza, ishawa yesandla kunye neshawari yokutshiza esecaleni.
Ishawa ephathwa ngesandla iyimfuneko kwikhaya ngalinye, kwaye yeyona isetyenziswa kakhulu. Ingasetyenziselwa ukuhlamba ngokuyibamba ngesandla, okanye inokulungiswa kwisokethi okanye kwisitulo sokutyibilika.
2) Ukwahlulwe ngezinto eziphathekayo: Kukho izinto ezintathu eziqhelekileyo zeshawari, ezizezi iiplastiki zobunjineli be-ABS, ubhedu kunye nentsimbi engatyiwayo. Iplastikiiintloko zeshawa: Iintloko zeshawari ye-ABS ngoku zithatha ubuninzi bemarike, ngesabelo esimalunga nama-90%. Eyona ixhaphakileyoiintloko zeshawazezi zinto. Ishawa yeplastiki ye-ABS ineemilo ezahlukeneyo kunye nonyango lwenkangeleko, kwaye inokuphuhliswa ibe yimisebenzi eyahlukeneyo, elula kwaye elula ukuyisebenzisa. Ubheduintloko yeshawa: Ngenxa yeendleko kunye neengxaki zenkqubo, kukho iindlela ezimbalwa kunye neemilo ezilula. Imisebenzi ngokusisiseko i-single-function, kwaye inzima kwaye akulula ukuyisebenzisa. Okwangoku, zimbalwa kakhulu iishawa zobhedu emarikeni, kwaye zisetyenziswa kakhulu kunyango lomphezulu wePVD. , Maninzi amazwe angaphandle kunawasekhaya. Intloko yeshawari yentsimbi: Kunzima kakhulu ukwenza isitayile kunentloko yeshawari yobhedu. Umsebenzi ngokwesiseko ngumsebenzi omnye, ngoko ke isitayile kunye nesiseko somzekelo nazo zilula kakhulu. Nangona kunjalo, intloko yeshawa yensimbi engenasici ineenzuzo ezi-3: 1. Intloko yeshawari ingenziwa ibe nkulu ngobukhulu kunye neshawari ephezulu inde. I-Hekuan inokuba ngaphezu kwemitha enye, kwaye ihlala isetyenziswa kwisilingi yokuhlambela yeehotele eziphezulu okanye iivillas. 2. Ishawari ingenziwa ibe yincinci kakhulu, inxalenye encinci malunga ne-2MM, enobuhle obuthile kunye nokusebenza. 3. Iindleko ziphantsi kunezo zemvula zobhedu, ngoko ke imvula yensimbi engenasici ineemfuno ezithile zeemarike ngokubhekiselele kubhedu.
3) Ngokomsebenzi wokuphuma kwamanzi: iishawari zinokwahlulwa zibe ziishawa ezinomsebenzi omnye kunye neeshawari ezinemisebenzi emininzi. Iindlela eziqhelekileyo zokuphuma kwamanzi ziquka amanzi eshawa, amanzi okuphulula, amanzi ahlwahlwazayo (akwabizwa ngokuba ngamanzi e-columnar / amanzi athambileyo), amanzi okutshiza kunye namanzi axutywe (oko kukuthi, amanzi okuhlamba + amanzi okuphulula, amanzi okuhlamba + amanzi okutshiza, njl. njl.), kunye namanzi angenanto , Amanzi ajikelezayo, amanzi acocekileyo kakhulu, amanzi eengxangxasi, njl.njl iindlela ezahlukeneyo zokukhupha amanzi. Ngokusisiseko zonke iishawara zineesona sitshizi samanzi seshawa eqhelekileyo. Phakathi kweeshawari zasekhaya ezinemisebenzi emininzi, ishawari enemisebenzi emithathu kunye nentlanu iyona idumileyo. Kwiimarike zaseYurophu naseMelika, kukho imfuno eninzi yeeshawa ezinemisebenzi engaphezulu kwe-5, kwaye kukho iishawari ezisebenzayo ezi-9. Ngokwentelekiso, abantu basemzini banikela ingqalelo ngakumbi kumanzi eshawa. Amaqhinga.
I-4) Ngokwamanqaku omsebenzi wokutshintsha: ngokuyintloko tshintsha iswitshi, cinezela tshintsha.
Zininzi iindlela zokutshintsha, njengokujikeleza umqheba wokutshintsha, iswitshi yokutyhala, isigubungelo sokujikelezisa isigqubuthelo sobuso, njl. Ukutshintsha ukuguqula yeyona ndlela ixhaphakileyo yokutshintsha kwimarike, kwaye ukutshintshela okuphambili yeyona ndlela idumileyo yokutshintsha kwiminyaka yakutshanje. Zonke iimpawu ezaziwayo-kakuhle ziye zayisungula. Inokuthi iqhutywe ngesandla esinye, esilula kwaye silungele.
