About

Septic Metrics explains how septic systems work, what they cost, how to look after them and what to do when something seems wrong. It is written for US homeowners, home buyers and anyone who has just found out the house runs on septic.

What we cover

We publish national information on system basics, leach fields, maintenance, warning signs, costs and septic-safe products. We don't list contractors, and we don't publish city or service-area pages.

What we don't do

We don't sell septic services or products, and we don't take leads from contractors. The site earns money from advertising and may earn from affiliate links. See how that works.

How we work

Every guide lists its sources, and safety advice and cost figures get extra checks. Read how we check facts.
