Service Portfolio
Underground Utilities
Water mains, sewer lines, storm drains, septic systems, and deep excavation for residential, commercial, and municipal clients across Metro Detroit.
Underground Work Done Right
Underground utility work requires the right equipment, the right permits, and a crew that knows what they're doing. Mistakes underground are expensive, dangerous, and sometimes catastrophic. At Delpres Services, we handle water mains, sewer lines, storm drains, and septic systems for residential, commercial, and municipal clients across Metro Detroit — with the experience and equipment to do it correctly the first time.
We work in Macomb County, Oakland County, St. Clair County, and Wayne County. We know the local code requirements, soil conditions, and utility infrastructure in each area. Whether you're connecting a new build to city water and sewer, replacing a failing septic system, or installing storm drainage for a commercial site, we handle the permits, the excavation, and the restoration from start to finish.
What We Handle
Water Main Installation & Repair
New service connections, main replacements, and emergency repairs for residential, commercial, and municipal water systems.
Sewer Line Installation
Full sewer line installations and replacements using proper bedding, slope, and connection methods compliant with local codes.
Storm Drain Systems
Catch basins, culverts, retention drainage, and storm sewer installations for residential subdivisions and commercial sites.
Septic System Installation
New septic system design and installation including tank placement, drain field layout, and inspection coordination for rural and suburban properties.
Deep Excavation
Large-scale excavation with the right equipment for the job — from mini-excavators for tight residential access to full-size equipment for deep commercial work.
Emergency Utility Repairs
24/7 emergency response for broken water mains, sewer collapses, and urgent drainage failures. We have an emergency line for a reason.
Our Process
Site Assessment
We evaluate scope, call MISS DIG for locates, identify utility conflicts, and pull all required permits before any excavation begins.
Excavation
Digging to spec with the appropriate equipment for site access, depth, and soil conditions.
Installation
Pipe, fitting, and connection work completed to code with proper bedding material and backfill specification.
Inspection & Testing
Pressure tests, camera inspections, or other required testing completed and documented before final backfill.
Backfill & Restore
Proper compaction in lifts to prevent future settlement. Disturbed surfaces — concrete, asphalt, or lawn — are restored.
Common Questions
What is MISS DIG and why does it matter?
MISS DIG is Michigan's underground utility notification system (call 811 before you dig). Before any excavation, we call for locates — this identifies buried gas, electric, phone, and water lines so we don't accidentally hit them. It's legally required and critical for job safety. Every Delpres Services excavation starts with proper locates.
How do I know if I need a sewer line replacement?
Warning signs include slow drains in multiple fixtures, sewage odors inside or outside the home, unusually green or soggy patches in the yard, and recurring backups. We can run a camera inspection to assess the actual condition of your line and give you an honest recommendation — repair or replace.
Do you handle emergency utility repairs after hours?
Yes. We maintain an emergency phone line available 24/7 for urgent utility failures — broken water mains, sewer collapses, and critical drainage issues. Call (877) 6-DELPRES. We serve Macomb, Oakland, St. Clair, and Wayne Counties.
