WATCH: Here's what a 260-foot crane ride looks like.

When you talk about underground work, "heights" are not something that comes to mind. But to get into and out of our Tunnel Dewatering Pump Station project in Bratenahl, workers need to take this crane ride that may leave some of you catching your breath.

EVENT: Go underground and behind the scenes as we #FollowTheFlow during Infrastructure Week May 11

"Go with the flow" has a meaning of its own. "Follow the flow" is going to get a little more interesting.

May 11-15 marks the third year for Infrastructure Week, a national celebration of country’s infrastructure systems and the essential role they play in our economy. To celebrate Infrastructure Week 2015, the Northeast Ohio Regional Sewer District is planning a week-long series of behind-the-scenes tours for local media and elected officials, and you can #FollowTheFlow with the Sewer District all Infrastructure Week long and trace wastewater’s path from the sewer system to Lake Erie.

Here's what we're planning and we'll be covering it all week long on Twitter, Instagram and Periscope.

LOOK: Can you be afraid of heights 200 feet underground?

Can you say "Don't look down," when you're already 200 feet below the earth's surface? Based on the photo shown here, um yes.

This is the current state of construction of the Easterly Tunnel Dewatering Pump Station taking shape 240 feet under Bratenahl. Upon completion, this cavern will house enormous pumps capable of drawing more than 160 million gallons of wastewater per day from three of our Easterly plant's four storage tunnels.

The photo was taken from near the location of the star below.

Construction is scheduled to be substantially complete in 2016.
