What is the Klargester Gamma Septic Tank?
The Gamma septic tank is a two-stage, underground wastewater treatment unit. Unlike older traditional cesspits, it does more than store sewage—it provides a level of treatment by separating and breaking down solids before releasing the effluent into a soakaway or drainage field.
Its robust polyethylene construction ensures long-term durability without risk of corrosion or cracking. With its shallow-dig design, the Gamma tank requires less excavation, which reduces installation costs and environmental impact.
How the Klargester Gamma Works
-
Primary Settlement: Wastewater from the property enters the first chamber, where solids settle at the bottom to form sludge.
-
Scum Separation: Oils and grease float to the top, leaving the middle layer of liquid clearer.
-
Secondary Treatment: The partially treated effluent flows into the second chamber for further settlement.
-
Discharge: The clarified liquid effluent exits the tank into a soakaway system or drainage field, where it undergoes final natural filtration.
This simple yet effective process reduces pollution risks while keeping maintenance minimal.
