At Earthworks of Maine, we understand that a properly installed septic system is the backbone of a healthy, functioning property—whether residential, commercial, or rural. If you’re building a new home, upgrading an existing system, or facing the need for a septic replacement, our experienced team provides reliable, efficient, and code-compliant septic system installation and replacement services throughout Central and Southern Maine, including Augusta, Waterville, Lewiston, and surrounding areas.
Why a Quality Septic System Installation Matters
Your septic system safely treats and disposes of wastewater from your property. A correctly installed system prevents costly backups, environmental contamination, and health hazards. Poor design or installation can lead to early system failure, groundwater pollution, and expensive repairs.
That’s why choosing a trusted contractor who understands Maine’s soil types, regulations, and site conditions is essential.
