Home > Septic Tanks - Standard and Flatbed


Properties in densely populated locations, or in remote areas with no access to mains sewage, have several options for managing their wastewater. One of the most economical and hassle free wastewater management systems are septic tanks. These tanks are designed to hold raw sewage, and allow for natural bio digestion before it is released into the ground. 

Septic tanks are very cost effective, easy to install and ideal for domestic, commercial and industrial use. They consist of two or three chambers, into which solid waste settles at the bottom for partial treatment through anaerobic digestion. The effluent is then released into an underground drainage field. For release into water bodies, the effluent must be fully treated in a sewage treatment plant. 

The remaining sludge at the bottom of the tank must be removed periodically and sent to a treatment plant, to avoid clogging the soak pit and slowing down the digestion process. Septic tanks are an environmentally friendly method of handling wastewater on site, without the risk of contaminating soil or groundwater.

MP Tank Suppliers are leading suppliers of high quality and durable domestic and commercial septic tanks. Our range of Glass Reinforced Plastic tanks is perfect for use in all terrains and conditions. Made from 100% virgin resin with no chalk fillers, they are a tough, long lasting and cost effective solution to wastewater management. 


Advantages of MP Tank Suppliers Septic Tanks

Our Glass Reinforced Plastic tanks are the ideal choice when compared to traditional concrete or steel septic tanks. These old fashioned tanks are heavy and harder to install, requiring more digging, mortar and craftsmanship. Furthermore, they are susceptible to damage by tree roots which bore through concrete, corrosion from exposure to sewage chemicals and rust. This greatly increases the cost of installation, maintenance and repair. 

In contrast, our GRP septic tanks are easy and cheap to install and maintain. They therefore cost much less over the long run. 

Their advantages include: 

•Extra lightweight, making them easy to transport and install
•Keying-in lips and lifting eyes for easy position and anchoring
•Highly resistant to chemical exposure from raw sewage
•Do not rust, corrode or get damaged by plants
•Have an outer protective shell to allow for use in all ground conditions
•Available in onion shape for easy installation 
•Low profile tanks available for use in areas with hard rock or high water table
•Can be converted to sewage treatment plants with the addition of an optional conversion unit 
•Pedestrian frame and cover as standard
