Infiltrator Septic Tanks — FAQs

What is an Infiltrator septic tank?

Infiltrator septic tanks are injection molded plastic (polypropylene) tanks that replace traditional concrete. They're lighter, faster to install, and don't require a crane. The IM-1530 is Infiltrator's 1,500 gallon model, the largest in the IM series and a common choice for 4 to 5 bedroom homes.

What are the dimensions of the Infiltrator IM-1530?

The IM-1530 measures 62" W x 176" L x 55" H, with 1,537 gallons of working capacity (1,787 gallons total capacity). Despite its size it weighs only 501 lbs, allowing placement with a backhoe or excavator already on site. No specialized delivery equipment needed.

How much does an Infiltrator septic tank cost?

Infiltrator tanks range from about $919 for the 500 gallon IM-540 to $1,700 for the 1,000 gallon CM-1060 to $2,125 for the 1,500 gallon IM-1530, plus freight. Crane free installation typically keeps total project cost lower than concrete. See our 500 gallon IM-540 and 1000 gallon CM-1060 for smaller applications.

How long do Infiltrator plastic septic tanks last?

Infiltrator polypropylene tanks are engineered for a design life comparable to or exceeding concrete. The material doesn't crack, corrode, or degrade from septic gases. Infiltrator backs its septic tanks with a five year limited warranty against defective materials and workmanship, provided the tank is installed per their instructions by a qualified installer.

Can I install an Infiltrator tank myself?

Installation must follow Infiltrator's published instructions and local health codes. Most jurisdictions require a licensed installer to pull the permit, and Infiltrator's warranty itself requires installation by a licensed or properly qualified installer. The tank installs like concrete but without a crane: excavate, level bedding, set, connect, and backfill per spec. Download the official installation instructions from Infiltrator.
