About this project

Built for homeowner planning, not engineered outputs.

This site exists to give homeowners and homebuyers a faster starting point for septic budgeting, likely system class, and the next practical questions to ask before they request quotes.

What this site is for

The goal is to reduce permit anxiety and cost uncertainty without pretending the result is permit-ready.

  • Planning ranges for septic cost, likely tank size, and likely system class.
  • State-aware pages with official-source links, agency attribution, and last verified dates.
  • Short quote-request flow after the user has already seen value.

What this site is not

This product is intentionally conservative where inputs are weak or local conditions are unknown.

  • Not engineering design software.
  • Not permit-ready calculation software.
  • Not a code-compliance certification tool.

How data is handled

Research data is versioned in files and reviewed before it becomes publishable guidance. Runtime leads and events are stored separately for auditability and export.

  • Official sources are preferred for rules and permit process context.
  • Commercial sources are used only for broad public cost anchors.
  • Where rules are unclear, the estimate widens instead of inventing certainty.
Important note

Estimate-first and source-transparent

Every result should be read as a planning estimate that still needs local verification.
