Windley Key Transmission Main Replacement Project

What are we doing? 

We are replacing 8,250 linear feet (approximately a mile and a half) of the existing 30-inch transmission main in Windley Key with a new 36-inch cathodically-protected steel water main.

What’s a transmission main?

The transmission main carries your drinking water from the water treatment plant to your faucet.

Why does it have to be replaced?

Because clean drinking water is a MUST. As pipes age, they become more susceptible to corrosion, leaks, storm surge, and other effects.

Where is the new transmission main going?

The new transmission main will be between the Whale Harbor bridge crossing to just south of Snake Creek.

What is the project timeline?

Work is slated to begin in April 2024 and will take crews approximately one year to complete. Crews will work 24-hours a day, Monday through Friday and pause work for major holidays and events. 

How much will this project cost?

The Windley Key Transmission Main Replacement Project will cost approximately $15 million. The project will be partially funded by the Water Infrastructure Finance and Innovation Act of 2014 (WIFIA), a federal credit program.
