The Emergency Force Main Repair Project demonstrates David Mancini & Sons, Inc. (DMSI)’s rapid response capabilities and technical precision in handling critical utility emergencies involving large-diameter sewage transmission systems.

This emergency response project was initiated after a directional drilling contractor accidentally damaged active 72-inch and 54-inch prestressed concrete cylinder pipes (PCCP) — key components of the county’s main sewage force main leading into the treatment facility. DMSI was immediately mobilized to assess, isolate, and repair the damaged sections, ensuring swift restoration of service while minimizing environmental risk.

The DMSI team employed line stop technology to safely isolate the piping system and shut down sewage flow entering the treatment plant without requiring a full system outage. Once isolated, crews performed controlled excavation and inspection to accurately identify the break locations, assess the extent of damage, and implement precision repairs using specialized PCCP restoration techniques.

This emergency intervention required around-the-clock coordination with municipal agencies, ensuring all repairs were executed safely, efficiently, and in full compliance with environmental regulations.
