Presby Products are specified for many projects within our service area because designers see how they reduce treatment field size. Phoenix Precast offers a precast concrete septic tank with a Presby Maze installed and delivered for the designer/installer that requires this product. This comes as a complete package, so you don’t need to call an alternate supplier or coordinate having both on site during installation time.

• Reduces treatment field size
• Increases the life span of the treatment field

What is the Presby Maze® & How Does it Work?

The Presby Maze® separates and traps the suspended solids within the septic tank. A network of vertical mesh panels increases the travel distance. This larger surface area allows the suspended solids to separate naturally from the wastewater before it can exit the tank, increasing the lifespan and effectiveness of both the septic tank and the treatment field.
