refill

With little to no precipitation, the main water source of cities in the region are underground aquifers - rock layers that contain water-filled spaces - that were last refilled thousands of years ago.

Pumps are needed to refill high-elevation tanks to maintain water pressure.

Starbucks recently unveiled its brand-new Coffeehouse Code of Conduct, introduced free refills and revived its condiment bars.

Beginning today, Jan. 27, Starbucks customers must make a purchase to use the restroom, sit at a table or even refill a water bottle.

Gravity draws the water down into faucets, pools and hydrants below, and then the tanks are refilled with water pumped up from the city’s pipelines.
