Indawo egandaywe ngezitini zamanzi, indawo eluhlaza ecwile, ukubaluleka kwemvelo, inhlanganisela yezindlela zemvelo nezindlela zokwenziwa. Emadolobheni amaningi amakhulu naphakathi nendawo, izikhala eziningi eziluhlaza eziyisikwele, imigwaqo yepaki, kanye namaphrojekthi okuhlala aseqalile ukulandela umqondo wokwakhiwa kwamadolobha e-sponge. Idolobha elibizwa nge-sponge liwukudlala ngokugcwele ekuqoqweni kwemvula ngenxa yezakhiwo zomhlaba zakudala, ukungenwa kwamanzi emvula ngezindawo ezingokwemvelo ezingaphansi nendawo ezungezile, nokuhlanzwa kwemvelo kwekhwalithi yamanzi ngezimila, inhlabathi, amaxhaphozi, njll., okwenza idolobha libe njengesipontshi, elikwazi ukumunca nokukhulula amanzi emvula ngendlela eguquguqukayo, futhi livumelane nezimo zemvelo. Njengamanje, ngokwanda kwemizamo yokuvikela imvelo kanye nemvelo, imikhiqizo yezitini evunyelekayo ikhiqizwa kakhulu ngaphandle kokukhiqiza kusetshenziswa imigqa yokukhiqiza izitini evunyeleka ngokugcwele.

Amadolobha e-sponge awakwazi ukuqondwa kancane njengokuqoqwa kwamanzi emvula, ukugcinwa, nokusetshenziswa kabusha, futhi awawona ukongiwa kwamanzi nokulawulwa kwezikhukhula noma ukuvimbela ukugeleza kwamanzi nokugcwala kwamanzi. Sekukonke, bathatha ukuthuthukiswa komthelela ophansi njengombono oyisisekelo oqondisayo, bathatha imvelo yamanzi, imvelo yamanzi, ukuphepha kwamanzi, nemithombo yamanzi njengezinhloso zamasu, futhi bazuze intuthuko esimeme ngokuhlanganiswa kwengqalasizinda empunga neluhlaza. Uma kuqhathaniswa noguquko nokunakekelwa kwakamuva, ukuhlela nokwakhiwa ekuqaleni kanye nokusungulwa kwendlela yokuphatha nokulawula yesikhathi eside kubaluleke kakhulu. Kudingekile ukuqinisa umklamo wezinga eliphezulu ekuqaleni kokuthuthukiswa nokwakhiwa. I-Honcha ingumhlinzeki wesevisi wasekhaya ohlinzeka ngemishini ehlakaniphile esezingeni eliphezulu yemishini yezitini evunyelekayo, futhi imikhiqizo yezitini evunyelekayo ekhiqizwe imishini yenkampani iye yasetshenziswa ekwakhiweni kwamaphrojekthi esipontshi angena amanzi ezigcawini ezinkulu zedolobha le-alkali eChina, njengesidleke seNyoni kanye ne-East Chang'an Street. Sikholelwa ukuthi umqondo othi "isipontshi" kufanele uhlanganiswe kuwo wonke umjikelezo wokuphila wokwakhiwa kwephrojekthi. Ikakhulukazi ekukhiqizeni izitini ezivunyelekayo zesipontshi, ukungqubuzana phakathi kokungena kwamanzi aphezulu kanye nokumelana nokugqoka kanye nokumelana nokucindezela kufanele kunqotshwe ukuze kwakhiwe idolobha lesipontshi eliphezulu. Ngoba izinga eliphansi isipontshi permeable izitini ngeke nje ukwenza ukwakhiwa kwamadolobha isipontshi kuwa mfushane, kodwa futhi ukuletha ingcindezi enkulu ekunakekeleni okwalandela.
