The project presented unique challenges due to the historic nature of the sub-basement levels. Our team coordinated closely with building management to schedule work during off-peak hours, ensuring zero downtime for the high-traffic retail tenants.

The new CIPP lining has extended the life of the plumbing infrastructure by an estimated 50 years, providing a long-term solution that avoided the noise, dust, and cost of traditional open-trench replacement.

Excavation was conducted by hand to protect the 19th-century limestone foundation. We utilized a trench box system that fit within the narrow 5-foot clearance of the service entrance.

The restoration included matching the original sidewalk flagstones, leaving no trace of the major infrastructure work beneath. The timeline was critical, completing the work within a 48-hour municipal permit window.

The network included complex grease traps and storm separators that had not been serviced in decades. We removed over 5 tons of debris using high-vac trucks.

The final CCTV inspection provided the developers with a clean bill of health for the new residential conversion, satisfying all municipal requirements for occupancy.

Operating under flood conditions, our team installed bypass pumps capable of moving 3,000 gallons per minute. Once the water receded, we redesigned the control panel placement.

Elevating the controls 4 feet above the new FEMA flood plain datum has prevented future failures, ensuring the station remains operational even during severe storm surge events.

Our preventative maintenance program identifies potential blockages before they become emergencies. Using high-pressure water jetting, we scour the lines to remove grease accumulation.

This proactive approach has resulted in zero main-line backups over the last 3 years, significantly reducing emergency service calls and maintaining high resident satisfaction.
