Ngokwezibalo ezingaphezu kwesigidi esingu-1 umkhiqizi wephampu okhona emhlabeni wonke, ukukhiqizwa kokugeleza kwepompo okuhlukahlukene kusuka ngaphansi kwegalani ngomzuzu kuya kumalitha angaphezu kuka-500 ngomzuzu. Ukuthengiswa kwephampu ye-centrifugal yokuthengisa, ukuthengiswa kwephampu ye-diaphragm 73%, okunye ukuthengiswa okungu-9% kusuka kuphampu ye-rotary ephindaphindayo kanye. Kubathengi abaningi, isikhungo sikamasipala sokuhlanzwa kwendle yisona esithenga kakhulu, ngo-2007 sizofinyelelwa ku-$6.8 billion. Okwesibili ngokulandelana: ukuhlinzekwa kwamanzi kamasipala, amakhemikhali, ukucwengisiswa, amandla kagesi, uwoyela negesi, njll.
