The Tricel 6500 litre 25 Population Cylindrical Septic TankThis tank is suitable for granular installations because of its solid structure thus avoiding the need for using large amounts of concrete.
The Tricel heavy duty septic tank is a durable, well built unit.
Produces a high standard of discharge compared to the onion shape septic tank.
Tricel heavy duty septic tanks can be fitted alongside a BIOROCK or JEWEL unit for successful conversion to a sewage system.
About Septic TanksSeptic tanks are like sewage treatment plants – just on a smaller scale.They are chambered,vary in size (typical capacities 2800-5000 litres) and are used for properties with no mains drainage connection.
Septic tanks have an inlet from the waste pipe of the property and an outlet into the drainage field or soak-away. The term “septic” refers to the process of anaerobic bacteria (does not need lots of oxygen) breaking down and mineralizing waste discharged into the tank.
When waste enters the first chamber, solids settle and a surface scum forms a 'crust'. Settled solids then get digested by the bacteria and the remaining liquid waste enters the second and third chambers where more settlement of the waste happens – are you keeping up? Finally, excess water flows out via the outlet to the drainage field for further treatment from the soil. Any remaining solid waste must be removed periodically by tanker.
