FAQ
What information do you need to design my septic tank system?
I'll need your site address, household size or occupancy load, soil percolation test results if available, and any local health department requirements or lot survey.
Do you calculate the correct tank size for my household?
Yes, tank sizing is based on daily wastewater flow estimates using occupancy, fixture count, and local code minimums to ensure your system is neither undersized nor over budget.
Will this design pass health department or county approval?
All designs follow standard onsite wastewater system codes and setback requirements. Final approval depends on your local jurisdiction, but plans are prepared to meet standard submission criteria.
What if I don't have a soil percolation test yet?
I can guide you on how to obtain one, or work with available soil data to provide a preliminary design that can be finalized once testing is complete.
Can you handle drainage field or leach field sizing too?
Yes, drainage field and leach field sizing based on soil absorption rate is included starting at the Standard package, ensuring your full system functions properly long term.
