We read every message that comes through this page. If you spotted a number that looks off, want a new calculator, run a septic-adjacent business, or noticed something that needs fixing, this is the right place to send it. For questions about your own system, the answer almost always involves a licensed pro or your county health department, and we'll point you that direction.
What We Can Help With
If your message falls into one of these buckets, send it over.
- Site corrections. Wrong gallon count, broken link, table that doesn't match a state's current code, math that smells wrong on a calculator. Tell us the page and what looks off.
- Updates to state code pages. If your state changed its setbacks, gallon-per-bedroom requirements, percolation test standards, or pumping intervals, link us to the rule and we'll update the page.
- Suggestions for new calculators or guides. If there's a calculation you keep doing on the back of an envelope, we want to hear it.
- Business and partnership inquiries. Service providers, manufacturers, lenders, inspectors, real estate folks. If there's a useful overlap with what homeowners need, let's talk.
- Accessibility issues. If a page doesn't work with a screen reader, has bad contrast, or fails on your device, please tell us specifically what broke.
- Press, research, and citation requests. Send a quick note about what you're working on.
What We Can't Help With
We're a calculator and reference site, not a licensed engineering firm. A few things are outside what we can responsibly answer.
- Site-specific permit advice. Permitting depends on your parcel, soils, setbacks, and local health code. Your county or parish health department is the right call.
- Contractor recommendations. We don't keep a vetted installer list, and we won't make one up. Ask your county for licensed installers, or check your state's onsite wastewater association directory.
- System design for a specific lot. Sizing a tank and field for a real property requires a soil evaluation and a designer who can stamp the plan. Our calculators give planning estimates, not engineered designs.
- Diagnosing a failing system from a description. Soggy yard, sewage smell, slow drains: a local pumper or inspector can scope the tank and tell you what's actually happening in an hour or two.
If you're in an active failure or backup, skip us and call a local pumper today.
How to Reach Us
The form below is the fastest way. It lands in our shared inbox and gets read the same day. If you'd rather email directly, use [email protected], which goes to the same place.
Typical reply time is two to five business days. Site corrections and accessibility reports get priority. Press and partnership notes get a real reply, not a form letter, so they take a little longer.
We don't sell email addresses or sign you up for a newsletter when you write in. Your address is used to reply to your message and nothing else.
