What’s Included With Septic System Replacement

System Evaluation

We assess your existing septic system and site conditions to determine the most effective replacement approach. This evaluation helps ensure the new system is properly sized and suited to your property.

Septic System Design

Every replacement includes a professionally designed septic system built to meet current New Hampshire standards. Design considers soil conditions, household use, and long-term performance.

Permitting and Approvals

We coordinate required permits and approvals so your replacement complies with state and local requirements. This helps avoid delays and ensures the project moves forward smoothly.

Removal or Abandonment of Existing System

Old septic components are safely removed or properly abandoned as required. This step prepares the site for installation and prevents future issues.

New Septic System Installation

We install a new septic tank and soil treatment system using proven construction practices. Proper placement and installation are key to system reliability.

Aggregate and Drainage Materials

Quality sand and stone are used to promote drainage and protect system performance. Adequate aggregate helps extend the lifespan of your new septic system.

Final Inspection and Documentation

Once installation is complete, we perform final inspections and provide documentation for your records. This confirms the system is installed correctly and ready for use.
