About Sewage Treatment
You are new to domestic sewage treatment?
And then there are those systems that are so complicated that trained technicians are required to service the plant every time. Load-shedding and power surges adversely affect electronics and specialist equipment, and are no more reliable than most other systems. They just become difficult to manage, particularly when the homeowner has left the overseeing of the system to the grounds man, or garden service.
So, sewage treatment systems should be simple electrical & mechanical designs.
The Stink Factor
Wrong! In today’s lifestyle, we have come to the reality that our waste has some value, and particularly our domestic wastewater. Several Scarab clients have included our sewage systems as features when selling their properties, and it certainly is an asset, even offering images of the system.
And the stink factor – yes, this has some negative perceptions, as sewage does stink. But only when it’s sewage. Once sewage becomes properly aerated, (the aerobic stage) the smell stops, leaving an almost odourless condition - an earthy smell. Quite pleasant! When raw sewage is open to the air, will it smell. The large municipal systems (WWTW) do smell, since they are primarily open sewers, and this technology is classified as “activated sludge”. Very few package plants are based on this technology, since no household is prepared to have open sewers outside their kitchen. This technology is best suited for large municipal flows from towns and cities.
So, if your system stinks, its not working.

Buried Concrete & Plastic sewage systems
These underground sewage systems are favourites in Australia, but they are so much different. All our (SA) systems are either plastic, or fibre glass, but Ozzies are concrete, weighing maybe 6 tonnes. When they go in, they don’t ever come out. They don’t leak, implode, crack or float out the ground. But, they are a terrible design. Those down under are not too concerned about water quality.

Steel and Sewerage
Some sewerage treatment systems are supplied using shipping containers, and / or mild steel frameworks. Special coatings have been applied to metal parts, in the factory, which is essential, and offers great oxidization (rust) protection – while in the factory. These systems, do, however leave the factory, travel maybe 5000 - 10 000 kilometers, on dirt and dusty potholed tracks, through war zones, and flooded rivers to reach a remote mine-site in the African bush, where they get off loaded and reassembled using local inhabitants, without any damage to this coating? After 3 / 4years, the system is a rust bucket, and would require replacement – yet again. Manhandling these sewage systems in the factory are pretty easy, but on the remote mine-site, craneage is a must. The alternative - roto-moulded (plastic) tank systems, are easily manhandled into position. And they don’t rust, ever.
Most sewerage systems are manufactured using plastic roto-moulded tanks, although there are a few fibre-glass designs The roto-plastic base-material is flexible, U-V stabilized, tough and does not oxidize easily. The plastic itself is resistant to chemicals, sewage contaminants, and toxic / corrosive gasses. These tanks are easily welded, cut, and even shaped, often on site. We have repaired a few of our Scarab systems after damage occurred during delivery, and quite successfully.
