Kungani kunganconywa ukusebenzisa amanzi apholile abapholile ezindaweni ezinokuntuleka kwamanzi noma izinga lamanzi eliphansi?

Okokuqala, ukuntuleka kwamanzi kuzokwenza ukuthi uhlelo lokupholisa amanzi luhluleke ukusebenza ngendlela evamile.

Njengoba isiqandisi sipholiswa ngamanzi, amanzi okupholisa ayadingeka ukuze kuqinisekiswe ukusebenza okuvamile kwesistimu yokupholisa amanzi. Ukushoda kwamanzi kuzokwenza ukuthi uhlelo lokupholisa amanzi luhluleke ukusebenza ngendlela ejwayelekile. Ngenxa yalokhu, isiqandisi asikwazi ukufakwa esiqandisini futhi asikwazi ukugcwaliswa ngendlela evamile.

Okwesibili, ukusebenza kahle kokupholisa nokusebenza kuyancishiswa.

Isistimu yokupholisa amanzi ayikwazi ukusebenza ngendlela evamile, noma ukusebenza kahle kokupholisa kwesistimu yokupholisa amanzi kuphansi, okuzokwenza ngokwemvelo ukuthi ukusebenza kahle kokupholisa kanye nokusebenza kahle kwehle, ngoba uhlelo lokupholisa amanzi luyingxenye eyinhloko yawo wonke amanzi apholisa. isiqandisi.

Okwesithathu, izinga eliphansi lamanzi lizobangela ukuvaleka kwamapayipi.

Lokhu akunakugwenywa. Cabanga nje ukuthi izinga lamanzi liphansi futhi amanzi okupholisa aqukethe izinto ezihlukahlukene zangaphandle kanye nokungcola. Lapho ipayipi ngokuvamile lihanjiswa futhi lisakazwa, ipayipi lizovimbeka ngokwemvelo. Ipayipi livinjiwe, hhayi nje “ukuvinjwa” okubonwa phezulu. Kodwa-ke, kuzophinde kunciphise izinga lokugeleza nokucindezela kwamanzi, okuzoholela ngokwemvelo ekuhlulekeni okubi kakhulu kwesiqandisi esipholile ngamanzi.

Okwesine, izinga eliphansi lamanzi liholela ekupholiseni okungekuhle.

Njengoba amanzi okupholisa equkethe ukungcola, kuzokwenza ukuthi amanzi abe nomphumela omubi wokushisa ukushisa, okuzoholela kumphumela wokupholisa ompofu, futhi ukusebenza kahle kokupholisa kwesiqandisi esipholile ngamanzi kuzoba kubi ngokwemvelo. Phela, lonke uhlelo lokujikeleza luyathinta omunye nomunye.
