When it comes to septic system installation, you need more than just a contractor—you need a team with the knowledge, certifications, and experience to do the job right the first time. At Keystone Excavation Services, we provide complete septic system solutions for homeowners, businesses, and contractors across Pennsylvania.
Whether you’re building a new home, upgrading an outdated system, or replacing one that has failed, our PADEP-certified team manages every step of the process—from planning and permitting to installation and final inspection. We work closely with engineers, local authorities, and property owners to ensure your system is efficient, reliable, and fully compliant with Pennsylvania Department of Environmental Protection (PADEP) regulations.
We provide septic system installation services for both individual homeowners and professional contractors.
For contractors, we deliver dependable installation support that keeps your project moving on schedule and in compliance with all Pennsylvania DEP regulations. Whether it’s a new build or a large development, our experienced team handles the excavation, system installation, and site restoration so you can focus on the rest of the project.
For homeowners, we make the process clear and stress-free. From explaining your system options to guiding you through permits and inspections, we’ll ensure your septic system is installed correctly and built to last. Whether it’s a sand mound, an alternate system, or a simple holding tank, we take care of every step so you can feel confident your home is protected.
We install a wide range of systems to meet the needs of different properties and site conditions:
- Elevated Sand Mounds – A proven solution for properties with shallow soils or poor drainage, common throughout Pennsylvania.
- PADEP-Approved Alternate Systems – For lots not suited for traditional systems, we install approved alternatives such as:
- Premier Tech Ecoflo® Coco Biofilter Systems – A compact, sustainable option using natural coconut husk media.
- Eljen GSF (Geotextile Sand Filter) Systems – A modular, low-profile solution ideal for poor soils or tight lots.
- Small Flow Treatment Facilities (Stream Discharge Systems) – Designed for properties without adequate soil absorption areas, these systems safely treat and release effluent into nearby streams.
- Holding Tanks – For properties unable to support other systems, we install holding tanks that provide reliable wastewater storage with regular maintenance.
