Izitanki zesedimente zesilisa ziyizibuko ezingabi nesikhathi eside ezinamandla, zinconywa ukusula isilisa kabefore kusetyenziswa kuzinto eziphambili. Bheka umfula omubi onemithi nezinye izinto ezihlukumeza emanzini. Isitanki sesedimente siyisikhumba esispeciale lapho isilisa esimbi sibaleka ngisho kwezinsuku. Uma isilisa sisekile, izinto ezingabi nesikhathi eside njengomthi nesilisa sibaleka kuqonda futhi sifika emzini. Lezi zinto ezisibalekile ziyichazwa ngokuthi yizisilisa. Isilisa esihle sibaleka emafuleni, sibaleka ukuthi sithathelwe ukuthi sijwe noma ukuthi sisebenzise kuzokufa noma kuzokwenza izinto. Kuyinto encane kodwa enobuhle ukususa izinto ezingafanele, okwenza isilisa sibe yinkulu kakhulu kubo bonke. KuDinghui, sizazi ukuthi isilisa esihle sibizwa kangakanani, futhi sizakha izitanki ezihle ezinokwenza umsebenzi wabo kahle
Uyazi, uma ngasebenze ngokwesilisa kwanje, ngabonakala ngokukhulu ukuthi amakhampani angasusa imali engaphezu kwalokho ngezinqumo ezihle. Akuyiyo kuphela ngokusula isilisa, okuphambili kakhulu, kodwa futhi ngokubhekana ngokuhle nezimali. Futhi lokhu kukuphi isitanki esihle isitanki sokubeka amasweli njengamaDinghui akhanya. Cabanga ngalokhu: uma usebenzisa amanzi ukwenza iphepha noma izindwangu, kudingeka ahlanzeke kahle. Ukungcola nokungcola okuningi kakhulu kungavala imishini, kuyiphule, kubangele izinkinga ezibizayo. Izindleko zokufaka ezinye izingxenye noma zokumisa ukukhiqizwa zingamathani, kanye nesikhathi esilahlekile. I-Dinghui tank isebenza njengendlela yokuqala yokuzivikela, ibamba izinto ezimbi kusenesikhathi. Njengesihlungi esinamandla sokuphakela amanzi phambi kwemishini ebucayi. Lokhu kusho ukuthi imishini ayiphuki, ayigqoki, futhi ihlala isikhathi eside. Omunye umdayisi wasesitolo sokudla wayenezipayipi ezivaleke izinhlayiya, esebenzisa imali eningi ekuhlanzeni. Ngemva kokufaka amathangi aseDinghui, ukugcinwa kwehla cishe ngo-30% ngonyaka wokuqala. Ukonga okukhulu emalini engenayo. Amanzi ahlanzekile asho ikhwalithi engcono yomkhiqizo. Ezokwelapha noma ezobuchwepheshe, ukungcola, ukucekela phansi izinto, izinto zokuphelelwa yisikhathi. Amathangi ethu asusa ukungcola ngempumelelo, ngakho amanzi asezingeni eliphakeme ahlala njalo. Ngaphezu kwalokho, uhlangothi lwemvelo: susa imfucumfucu, wehlise umthwalo ohlelweni, wehlise ukusetshenziswa kwamandla, mhlawumbe wehlise izimali zokukhishwa. Ubuchwepheshe bukaDinghui buwenza kahle umsebenzi ngokuhamba kwezinto nokwakhiwa kwezinto ezenza imfucumfucu ihlale ngokushesha, ngaphandle kwendawo enkulu noma amandla. Ezindala ziyiziqephu ezinkulu nje ezingalungile. Esethu sisebenzisa ubuchwepheshe obuhlakaniphile, njengama-baffle okuhambisa amanzi kancane ngendlela efanele, noma ukuma ukuze imisinga iqondise kahle imfucumfucu. Ngalokhu, inqubo iba bushelelezi. Kulula futhi ukuyinakekela: ukuhlanza imfucumfucu kulula, ngokuvamile kwenziwa ngokuzenzakalelayo, kunomsebenzi omncane nesikhathi sokuphumula. Isebenzisa indlela ephelele, igcina izindleko zisuka nje, ikhokhe ngokuvimbela izinkinga ezinkulu, iqinisekise ukusebenza kahle.
