If the lake level falls to 469 feet, Raw Water Pump 3 would no longer be able to pump water from the lake, Hickey said; at 470 feet, Raw Water Pump 2 would be in the same situation.
Uma izinga lechibi liwela ezinyaweni ze-469, i-Raw Water Pump 3 ngeke isakwazi ukupompela amanzi echibini, kusho uHickey; ezinyaweni ze-470, i-Raw Water Pump 2 ibizoba sesimweni esifanayo.
