About the Project
Donegal Services’ Sewer Division recently completed underground utility work for a luxury home development in downtown Naperville, Illinois. The project included installation of a StormTrap® stormwater management system along with new water mains to support the growing residential community.
The StormTrap® system required precise excavation, engineered stone base preparation, and coordinated structural placement. To ensure safe and accurate installation, Donegal worked alongside Atlas Crane to lift and position system components efficiently within the excavation footprint. Proper coordination between crane operators, ground crews, and utility installers was critical to maintaining schedule and safety standards.
In addition to the stormwater system, our team installed new water mains in accordance with municipal specifications, ensuring long-term reliability for the development’s infrastructure.
Working in a high-visibility downtown Naperville environment required careful staging, traffic awareness, and disciplined site management. From trenching and pipe alignment to inspection coordination and final backfill, every phase was executed with precision.
This is what we call Flat Out Sir — strong partnerships, professional crews, and infrastructure built the right way the first time.
Key Project Stats
- Location: Downtown Naperville, Illinois
- Scope: StormTrap® system installation, new water mains, excavation, backfill
- Partner: Atlas Crane (crane placement support)
- Project Type: Luxury residential housing development
- Division: Donegal Sewer Team
- Final Condition: Backfilled, compacted, and build-ready
- Completion: On schedule and fully compliant with local utility standards
The Challenge
Installing a StormTrap® system in a luxury residential development presented several technical challenges:
- Large excavation footprint and structural stone base requirements
- Coordinated crane lifts for system components
- Precise water main grade and alignment control
- Tight downtown access and staging constraints
- Strict municipal inspection and compliance standards
This project demanded experienced underground utility professionals capable of managing heavy components, engineered stormwater systems, and complex scheduling.
The Solution
Donegal’s sewer team handled excavation, StormTrap® placement, water main installation, and final backfill operations with strict adherence to engineering plans.
By partnering with Atlas Crane for safe and efficient lifting operations, we ensured accurate placement of stormwater system components while maintaining a clean and controlled jobsite.
Our crews completed trenching, bedding, alignment, testing, and compaction to deliver a site fully prepared for vertical construction.
We don’t just install pipe and infrastructure.
We build communities from the ground up — Flat Out Sir.
Final Result
The StormTrap® stormwater management system and new water mains were successfully installed, inspected, and approved. The site was backfilled, compacted, and prepared for the next phase of luxury home construction.
Donegal Services continues to provide professional sewer, water main, and stormwater installation services throughout Naperville and across Chicagoland — delivering performance, reliability, and execution Flat Out Sir.
