Onsite Sewage Maintenance With Septic Tanks and Accessories

A septic tank can make it possible to treat sewage for small, onsite plumbing. A septic tank system works underground. They're useful for rural areas where there's no centralized sewage system to treat wastewater from bathrooms, kitchens and other drains.


A small septic tank is suitable as an RV accessory or a smaller onsite sewage system. State codes should be reviewed before buying a new septic tank to ensure it meets code. Small septic tanks are usually made of fiberglass or PVC for durability, especially if they'll be installed underground. Look for two-compartment septic tanks with tees and gaskets included for an efficiently-running tank.


To maintain your tank, septic tank chlorine tablets can be used with RV holding tanks and septic tanks to break down waste and tissue. Look for drop-in tablets that won't stain toilets or harm the environment. Tablets can give off pleasant odors to keep your RV or outdoor toilet smelling fresh for days.
