Submerged Water Main Upgrade- Madeira Beach to Treasure Island

Project ID

006167A

Project Location

29th Ave E to Key Capri, Madeira Beach to Treasure Island

Project Status

Design: Not started

Project Overview

This project aims to replace one 24-inch cast iron and one 20-inch ductile iron submerged water main between Madeira Beach and Treasure Island.  These deteriorated pipes have been subject to a corrosive marine environment, and have reached the end of their service life, necessitating the installation of more durable piping.

The replacement piping will be approximately 2,000 linear feet of 30-inch DR-11 High-Density-Polyethylene (HDPE) and 2,000 linear feet of 26-inch DR11 HDPE pipes. With advanced directional drilling techniques, the new piping is projected to extend the life of the water main system, enhancing long-term reliability and performance for the community.

Project Goals

  • Replace deteriorated cast iron mains with durable, corrosion-resistant materials.
  •  Minimize environmental and surface disruption using horizontal directional drilling.
  •  Extend the service life of critical underwater infrastructure.
