Amapayipi omliloziyingxenye ebalulekile yengqalasizinda yethu yezokuphepha yomlilo kazwelonke. Asetshenziswa abezicishamlilo ukuze bathole amanzi aphuma kumapayipi amakhulu asendaweni. Itholakala kakhulu emigwaqweni yomphakathi noma emigwaqweni emikhulu ngokuvamile ifakwa, iphethwe futhi inakekelwa izinkampani zamanzi noma iziphathimandla zendawo zokucima umlilo. Nokho, niniizicishamlilozitholakala endaweni yangasese noma yezentengiso umthwalo wesondlo ulele nawe. Amapayipi okucisha umlilo angaphansi komhlaba adinga ukuhlolwa nokunakekelwa njalo ngokuhambisana ne-BS 9990. Lokhu kuqinisekisa ukuthi azosebenza esimweni esiphuthumayo okuvumela abezicishamlilo ukuthi baxhume amapayipi abo aseduze nomlilo ukuze bathole amanzi kalula.

Amanzi angaphandleumshini wokucisha umliloIngabe indawo yokuhlinzekwa kwamanzi exhunywe nenethiwekhi yokulwa nomlilo inethiwekhi yangaphandle yokwakha. Isetshenziselwa ukuhlinzeka ngamanzi ezinjini zomlilo ezivela kunethiwekhi kamasipala yokuphakela amanzi noma inethiwekhi yamanzi yangaphandle lapho ingekho ingozi yezingozi zezimoto noma umkhathi obanda. Kungcono ukusetshenziselwa ezitolo ezinkulu, izikhungo zokuthenga, amakolishi, ezibhedlela, njll. Kungaphinde kuxhunywe kuma-nozzles ukuvikela umlilo.
