Ithangi lokunweba liyisitsha esishiselwe ngepuleti lensimbi, kunezinhlobo ezahlukene zobukhulu bemininingwane ehlukene. Amapayipi alandelayo avame ukuxhunywa ethangini lokunweba:
(1) Ipayipi lokwandisa Lidlulisela umthamo okhuphukile wamanzi ohlelweni ngenxa yokushisa nokukhulisa liye ethangini lokukhulisa (elixhunywe emanzini ayinhloko okubuyisa).
(2) Ipayipi lokugcwala lisetshenziselwa ukukhipha amanzi angaphezulu ethangini lamanzi adlula izinga lamanzi elibekiwe.
(3) Ipayipi elisezingeni loketshezi lisetshenziselwa ukuqapha izinga lamanzi ethangini lamanzi.
(4) Ipayipi lokujikeleza kwamanzi Uma ithangi lamanzi kanye nepayipi lokukhulisa lingase liqine, lisetshenziselwa ukujikeleza amanzi (enkabeni engezansi yethangi lamanzi, elixhunywe emanzini ayinhloko okubuyisa amanzi).
(5) Ipayipi lendle lisetshenziselwa ukulahla indle.
(6) Ivalvu yokugcwalisa amanzi ixhunywe ebholeni elintantayo ebhokisini. Uma izinga lamanzi liphansi kunenani elibekiwe, ivalvu ixhunywe ukuze igcwalise amanzi.
Ngenxa yezizathu zokuphepha, akuvunyelwe ukufaka noma yiliphi i-valve epayipini lokunweba, ipayipi lokujikeleza kanye nepayipi lokugcwala.
Ithangi lokunweba lisetshenziswa ohlelweni lokujikeleza kwamanzi oluvaliwe, oludlala indima yokulinganisela umthamo wamanzi kanye nokucindezela, lugwema ukuvulwa njalo kwevalvu yokuphepha kanye nokuphindaphinda njalo kwevalvu yokunweba amanzi ngokuzenzakalelayo. Ithangi lokunweba aligcini nje ngokudlala indima yokwamukela amanzi okunweba, kodwa futhi lisebenza njengethangi lokunweba amanzi. Ithangi lokunweba ligcwele i-nitrogen, engathola umthamo omkhulu ukuze ivumelane nomthamo wamanzi okunweba. Hlikihla amanzi. Ukulawulwa kwephuzu ngalinye ledivayisi ukusabela okuxhumene, ukusebenza okuzenzakalelayo, ububanzi bokuguquguquka kwengcindezi encane, ukuphepha nokuthembeka, ukonga amandla kanye nomphumela omuhle wezomnotho.
Umsebenzi oyinhloko wokusetha ithangi lokunweba ohlelweni
(1) Ukwanda, ukuze amanzi ahlanzekile ohlelweni abe nendawo yokwanda ngemva kokufudunyezwa.
(2) Lungisa amanzi, lungisa inani lamanzi alahlekile ngenxa yokuhwamuka nokuvuza ohlelweni bese uqinisekisa ukuthi iphampu yamanzi ahlanzekile inomfutho owanele wokumunca.
(3) Ukukhipha umoya, okhipha umoya ohlelweni.
(4) Ukulinganisa, ukulinganisa izinto zamakhemikhali zokwelapha amanzi aqandisiwe ngamakhemikhali.
(5) Ukushisa, uma kufakwa idivayisi yokushisa kuyo, amanzi abandayo angafudunyezwa ukuze kufudunyezwe ithangi.
