Concrete Septic Tanks
Omega Precast manufactures premium precast concrete septic tanks engineered for 30+ year performance.
Our reinforced concrete septic systems resist buoyancy, handle heavy traffic loads, and maintain structural integrity in challenging soil conditions.
Trust by the leaders
Why Choose a Concrete Septic Tank?
Concrete septic tanks stay put, resist buoyancy in groundwater, and protect pipe alignment under traffic and cover.
Superior Structural Integrity
Steel-reinforced concrete construction provides 3x stronger structural performance than lightweight alternatives
Buoyancy Resistance in High Water Tables
Heavy concrete construction prevents floating in Concrete septic tanks weigh 8,000-15,000 pounds, preventing flotation in saturated soils.
Traffic Load Protection
H-20 traffic rated concrete septic tanks handle vehicle loads. Protects inlet and outlet connections from damage that causes expensive system failures
30+ Year Service Life
Concrete septic tanks maintain shape and structural integrity for decades. Plastic tanks can deform under soil pressure, creating maintenance issues within 10-15 years.
How a Concrete Septic Tank works
Simple, effective wastewater treatment that keeps solids contained and prevents clogs
Solids Stay Inside
This flow path keeps solids contained within the tank, reducing risk of clogs and sewage backup in your system.
04
Outlet to Drain Field
The outlet pipe carries treated wastewater toward the drain field for soil-based treatment and final processing.
03
Clarification
Clarified liquid and effluent move to the second chamber for additional treatment and separation
02
Primary Treatment and Solids Separation
Wastewater enters the inlet baffle where heavier solids settle as sludge. Grease and oils float as scum layer. Anaerobic bacteria begin breaking down organic matter in the first chamber.
01
Clarification
Partially treated effluent flows to the second compartment through the outlet baffle. Additional settling removes suspended solids before discharge to the drain field.

Tell us about the project you’ve been planning, your desired timeline, and any challenges you’re facing. With our expert team will recommend the perfect concrete solution that optimizes both cost and quality while exceeding your expectations.
Right Size & Working Capacity
Choosing the right size involves several factors beyond just bedroom count. We help determine working capacity so your system handles weekends and guests without stress.
Proper capacity improves disposal performance and reduces long-term maintenance cost.
We help determine the right working capacity with simple questions about your actual usage patterns.
