How Biologic™ SR2 Septic Works

Helps control odors and supports drainfield health as part of regular maintenance – effective septic care for less than $15/month.

Septic Systems

There are many types of septic systems, but most follow the same basic steps: wastewater leaves your home, solids settle in the tank, and clarified water flows to the drainfield.

SeptiCorp

Your septic system has two main parts:

The Tank
where solids settle to the bottom and lighter materials float, while liquid effluent flows out.

The Drainfield
where liquid effluent soaks into the soil and gets naturally filtered as it moves through the ground.
