All About Sewage Systems
Package Plants - What are they?
Package plants, by design, are prefabricated sewage systems which are installed on site, specifically to treat that sites wastewater.
These systems are designed (or should be) to cater for a set daily volume, and the treated wastewater is ideally recycled within the property.
Package plants are manufactured from a variety of materials, mainly plastic, fiber glass and steel. Installation is either above or underground.
Generally, the better systems are modular, and therefore able to treat a range of daily volumes.
And then these systems are specifically designed for domestic sewage, as opposed to commercial or industrial wastewater. Establishments like butcheries, bakeries, fast-food outlets, petrol stations, restaurants, and clinics / hospitals produce a variety of chemicals, disinfectants and high biological oxygen demand, so normal systems just wont cope. In many cases, the water from these establishments are toxic, and would be treated with further chemicals, to allow biological action to take place.

The more common system, like the Scarab, are above ground, so you can see them, and know if they stop working. Most are manufactured from roto-moulded plastic.
However, a few are made from used shipping containers, with built-in compartments to facilitate the required biological processes. They would arrive on site, like any other container, off loaded with a crane and "plugged in". Sewage is highly corrosive, and anything made from steel will rust, and therefore have a limited lifespan, despite being extensively corrosion protected.
Package Plants - Inventing flight
But, those were exciting times. There were no rules. and no really complete products, There was an urgency to get to market, and the rush left some designs with serious design flaws, which are still evident in the very same products on the market today.
Scarab was different. We started off with all the correct equipment, designs and technology, based on extensive research. We used a very rare commodity in this industry - common sense! What didn't work on other systems, we discarded in our design. What worked, we kept, modified, updated and tested. When we were informed that a particular design didn't work, we double checked.
