Commercial Drain & Sewer Services
Elge Plumbing Company installs complete drain and sewer systems for commercial buildings, institutional facilities, and large-scale developments. From underground sanitary lines and storm drainage to grease waste and trench drains, we deliver plumbing infrastructure that meets both construction deadlines and code compliance standards.
These systems are often among the first installed on-site and are essential for inspections tied to slab pours, foundation work, and overall construction sequencing. We support this phase with strong planning, early coordination with civil teams, and a deep understanding of inspection timelines. From laying out a trench drain network for a commercial kitchen to connecting sanitary mains for a senior living complex, Elge keeps the schedule moving forward.
With over 100 years of experience, we understand how to integrate storm and sewer scopes into the broader construction plan. Our team helps clients avoid slab conflicts, utility delays, and costly rework. We self-perform across New England and the Southeast and extend service to key national markets through a trusted subcontractor network.

Our team installs full-scope drain and sewer systems to support commercial projects from early excavation through to final plumbing tie-ins. We bring both the technical expertise and manpower to deliver under pressure while coordinating closely with other trades on site.
- Underground sanitary sewer piping

These scopes can be integrated into full plumbing packages or handled as standalone phases depending on the project timeline.
Code-Compliant & Inspection-Ready
Drain and sewer systems must meet precise code requirements to pass inspection and avoid rework. Elge plans each install carefully, starting with layout reviews, trench elevations, and slope planning, and finishing with system testing and inspector coordination.
- All systems installed per state and local code
- Slopes, cleanouts, and venting verified during installation
- Testing services include air or hydrostatic pressure verification
- Walkthrough preparation and on-site inspector communication
- Coordination with AHJs, civil engineers, and utility authorities
- As-builts, cut sheets, and inspection documentation provided as needed
By focusing on accuracy and readiness from the start, we help eliminate delays tied to underground approvals or missed utility milestones.

Supporting Systems
Commercial drain and sewer systems do not operate in isolation. Elge ensures every underground system integrates smoothly with interior plumbing and mechanical installations that follow. From slab coordination to vertical risers, we plan for what comes next.
- Interior tie-ins for storm and sanitary lines
- Coordination with slab pours, embeds, and core drilling
- Piping stub-ups and protection during concrete work
