Commercial & Residential Underground Utilities
Built right, below the surface.
A successful project doesn’t start at the walls or the roof—it starts in the ground. Cinnabar Construction provides complete underground utility services for both commercial and residential properties, handling the critical infrastructure that keeps buildings dry, sanitary, and functioning the way they should.
From city sewer tie-ins and underground retention to wastewater evaporation beds and other buried systems, our team focuses on doing the work right the first time so you don’t have to worry about what you can’t see later.
Overview
Underground Utility Services
We provide turnkey installation and coordination for a range of underground systems, including:
- City sewer tie-ins for new builds, remodels, and septic-to-sewer conversions (commercial and residential)
- Underground retention systems to manage stormwater on-site and protect structures and surrounding properties
- Underground utilities for water, sewer, and related services serving homes, multi-family, and commercial buildings
- Commercial wastewater evaporation beds and other specialty wastewater solutions
- Coordination with grading, drainage, and foundation work to keep the entire site working as one system
A Coordinated, Code-Compliant Approach
Underground utilities must be planned and installed with precision. Cinnabar Construction works closely with engineers, inspectors, and local jurisdictions to ensure:
- Compliance with city and county codes and requirements
- Correct elevations, slopes, and connections for sewer and water lines
- Proper integration with septic systems or city sewer, depending on the project
- Thoughtful planning around access points, cleanouts, and future maintenance needs
Our crews understand both the technical requirements and the real-world conditions in Arizona, from soil types to extreme weather. That experience helps prevent issues like improper flow, backups, or premature system failure.

Whether you’re a property owner, developer, or general contractor, we can take ownership of the underground utility portion of your project so it’s done safely, correctly, and on schedule.
- For homeowners and property owners, we help you understand your options (septic vs. sewer, tie-ins, retention needs) and walk you through each step.
