Maybe you just bought a house and learned there is a tank buried in the yard. Maybe the drains slowed down on a Sunday morning. Or maybe you are selling and the buyer's inspector wants to see your septic records. However you got here, you have questions about a system most people never think about until they have to.
Tank & Field exists for that moment. We explain how septic systems work, what maintenance they need, what repairs should cost and when something is actually urgent, all in plain English.
Know what is under your lawn. That is the whole idea.
Why we exist
Our mission: make the buried part understandable
About 1 in 5 US homes runs on septic instead of city sewer. That means millions of homeowners are responsible for a private wastewater system, and most of them got no manual with it.
Our mission is simple. Give those homeowners the same clear explanation a good inspector would give at the kitchen table. What the tank does. What the drain field does. When to pump, what it should cost and which warning signs mean call someone today.
We write for the owner, not the industry. When an additive is a waste of money, we say so. When a drain field quote deserves a second opinion, we say that too.
What you get on this site
- Tank & Field explains septic tanks, drain fields, aerobic and mound systems in plain English for US homeowners.
- Every guide opens with an At a glance box: what it covers, which systems it applies to, the typical cost range, how urgent it is and whether it is a homeowner job or a pro job.
- Problem articles lead with a Do this now box, so a backup or a soggy yard gets the next step first and the background second.
- Cost guides give dollar ranges by US region, the factors that move the price and a Last checked date.
- State rules pages name who regulates septic, whether an inspection is required at sale and link to the official source.
How we approach every guide
We write the way an experienced septic inspector talks to a neighbor over the fence. Concrete numbers where they help: tank sizes in gallons, lid depths in inches, costs as dollar ranges with the year noted. Technical terms get explained in a few words at first use, so scum layer, baffle, effluent filter and biomat never slow you down.
Problem articles put the next step first. If you have sewage in the basement, you should not have to read six paragraphs of history before learning what to do.
How-it-works articles use one labeled cutaway diagram, drawn the way an inspector would sketch it, showing the tank, baffles and drain field in a single view.
Made for homeowners
Who this site is for
First-time septic owners who want to know what is buried in the yard and how to keep it healthy. Buyers and sellers facing a septic inspection at closing. Owners with a problem today, from slow drains to standing water over the field. And planners who want a maintenance calendar and a fair idea of pumping prices before they call.
Landlords with rentals on septic and people building on rural land will find their questions answered here too.
One group we do not write for: septic contractors, pumpers and engineers. If you want industry depth, a trade journal will serve you better. If you want to understand your own system well enough to make a good decision, you are in the right place.
How a guide is built
Our approach, step by step
Start with the situation
Each guide opens with the concrete moment that brings you in, never a dictionary definition. A slow drain, a first pump-out, a sale inspection.
Give the next step early
Problem articles lead with a Do this now box. You get the immediate action first, the background after.
Put real numbers on it
Cost guides show dollar ranges by US region, what moves the price up or down and the questions to ask before you hire, with a Last checked date.
Say when not to spend
Honest advice includes advice against. Some products and some quotes are not worth your money, and we say that plainly.
