“...Eight pumps will push 54-million gallons of water 10 miles uphill every day...”

Wow, those pumps must be really low.
I wonder why they have to push the water so high?

I wonder why they have to push the water so high?

Water flows downhill, so gravity pressurizes the water supply. That's why municipal water is often kept in those mushroom-shaped towers—as much water as possible is kept as high as possible.
