54-Inch Redundant Sewer Installation — Euclid Avenue

The 54-Inch Redundant Sewer Project along Euclid Avenue represents a major infrastructure improvement initiative led by David Mancini & Sons, Inc. (DMSI) for the City of Miami Beach, designed to enhance wastewater reliability, system redundancy, and long-term service capacity in one of the region’s most active and high-profile urban corridors.

This critical three-phase project introduced a 54-inch redundant sanitary sewer system spanning multiple city blocks and connecting major pump stations and distribution lines. The project involved both open-cut and horizontal directional drilling (HDD) methods, carefully executed to minimize disruption to the city’s heavily trafficked, tourist-oriented environment.

DMSI implemented an extensive public outreach program throughout the project duration, including weekly public advisories, homeowner coordination meetings, and ongoing stakeholder communications — ensuring transparency and community engagement at every stage

  • Phase 1: Installation of a 54-inch PCCP sewer along Washington Avenue from Commerce Street to Commerce Court, totaling approximately 191 linear feet. This segment was installed via open-cut trenching, involving careful planning around existing utilities and high-density commercial activity.
  • Phase 2: Construction of 30-inch and 36-inch ductile iron (DI) sewer lines and approximately 1,000 linear feet of 54-inch PCCP sewer along 11th Street, connecting to Meridian Avenue and Pump Station #1. This phase also included the design and installation of 405 linear feet of multiple sewer mains and a 24-inch force main connection, all completed using the open-cut method.
  • Phase 3: Final integration of Phases I and II with the installation of approximately 4,450 linear feet of 54-inch HDPE sewer along Euclid Avenue (from 11th Street to Washington Avenue) and Washington Avenue to Commerce Court. This segment was installed using Horizontal Directional Drilling (HDD) and included tie-ins to Pump Station #31, completing the redundant network with minimal surface disturbance.

  • Over 6,000 linear feet of large-diameter sewer mains installed using both open-cut and HDD methods.

  • Multi-phase coordination across Washington Avenue, 11th Street, and Euclid Avenue, ensuring seamless integration between new and existing systems.

  • Connections to Pump Stations #1 and #31, enhancing redundancy and operational reliability for the city’s wastewater network.

  • Comprehensive public communication program, including weekly notices, homeowner meetings, and outreach initiatives to maintain transparency.

This project stands as a testament to DMSI’s leadership in complex municipal sewer construction and urban infrastructure modernization. By combining engineering innovation, advanced installation methods, and exceptional community coordination, DMSI successfully delivered a redundant 54-inch sewer system that enhances Miami Beach’s resilience, service capacity, and sustainability for decades to come.
