Septic Tanks: Precision in the Details
Septic tanks might not be the most glamorous of all the things we make with concrete, but they may just be one of the most important. That’s why we take great care and precision when making ours. After all, your septic tank is responsible for quietly doing some of the most crucial work, and it needs to be built to last.
What is a Septic Tank?
A septic tank is an underground, watertight container that treats wastewater from your home or building.
As water flows into the tank, solids settle at the bottom, forming sludge. Oils and grease float to the top, creating a scum layer. The middle liquid layer — called effluent — then exits the tank and is further filtered by a drain field.
It’s the foundation of any property without a centralized sewage system, making it a critical component of your home’s infrastructure.
