When wastewater leaves your home, it all flows into the same place: the septic tank. Here, it separates into three layers. Fats, oils, and greases rise to the top, forming a scum layer. Some particles lose their buoyancy and settle to the bottom of the tank, forming a sludge layer. The middle layer is the clear zone, which eventually makes its way out to the field lines. Modern day septic tanks are usually made of concrete or plastic.
Both modern day concrete and plastic tanks are known for their structural integrity. During the manufacturing process, our tanks are treated to combat the concrete corrosion problem.
Both concrete and plastic tanks are excellent products and have their place. The best material to choose differs from project to project. Example: you may want to use a plastic tank on a small, wooded, steep building site where it may be hard to get to in a big truck.
When it comes down to it, a tank is a tank, no matter what it is made of. The best material to choose differs from project to project, which is why it is always best to know the pros and cons early on in order to make an informed decision.
