Our Installation Process
Installing a septic system in Central PA requires coordination with local Sewage Enforcement Officers (SEOs) and an understanding of regional terrain.
1. Site Evaluation & Stake Out
We assist in the initial stages, ensuring your site is ready for the SEO’s deep probe and perc testing. We follow the approved design plan to stake out the exact location of the tank and absorption area, verifying all isolation distances from wells and property lines.
2. Tank Excavation & Placement
We handle the precision digging required for your septic tank, creating a level, stable base to prevent future settling or pipe stress. We install concrete or poly tanks depending on your specific design needs, ensuring all inlets and outlets are set to the correct elevations for proper flow.
3. Absorption Area (Drain Field) Construction
The “drain field” is where final treatment occurs. We prepare the ground through careful scarification to maintain soil porosity before installing:
- Standard In-Ground Trenches: For lots with suitable, well-draining soil.
- Seepage Beds: Efficient solutions for specific lot layouts.
- Chamber Systems: Modern, gravel-less solutions that often have a smaller footprint and high treatment capacity.
4. Sand Mound Systems
When soil has a “limiting zone” (high water table or bedrock), a traditional system is often not an option. We build Elevated Sand Mounds according to strict state codes, using the specific sand type and pressure distribution lines required for successful operation.
Reliable Site Service
- Equipment for the Job: We use the right machinery to handle the rocky terrain and shale common in the Susquehanna Valley without unnecessary damage to your lot.
- Inspection Coordination: We coordinate with your SEO for all required “open-hole” inspections before the system is backfilled.
- Full Site Restoration: From clearing the lot to the final grade and seeding, we handle the project from start to finish.
Frequently Asked Questions
What is the first step in getting a new septic system?
In Pennsylvania, you must first contact your local SEO for a permit and soil testing (probes and perc test). Once you have a design plan, we can provide an accurate installation estimate.
How long does installation take?
Most residential installations take 3 to 5 days once the permits are issued and the weather allows for proper soil handling.
What prevents a system from being covered immediately?
State law (Act 537) requires that no part of the system be covered until the SEO performs a final inspection and provides written approval.
