Advanced production method
SNIGO tanks are manufactured from polyethylene by modern process of rotational moulding. The automatic production method ensures the perfect stability and allows to
avoid manufacturing failures caused by human factor. All finished products are made with the highest accuracy. Polyethylene material used for the production can be easily recycled reducing waste and environmental impact.
SNIGO underground polyethylene tank is a perfect solution for many applications: domestic wastewater treatment, rainwater harvesting etc. Standard cylindrical modules are connected to get the required size of the tank. The tank volumes from 1000 to 12000 liters are manufactured to suit to the customer needs. SNIGO tanks can also be supplied with the integrated baffles. To facilitate the installation the inlet and outlet pipes can be connected from the end or from the top.
Design inspired by nature
SNIGO distinguished by the unique exterior design made by well-established British specialists. By developing the tanks the natural shapes have been implemented. The shape of a snowflake reflected in the tank’s design is not only very elegant but also providing great resistance to the external loads.
SNIGO’s manhole shaft is equipped with the integrated ladder ensuring easy and safe access into the manhole.
SNIGO provides a perfect load-bearing capacity by keeping the low weight of the product. The great stiffness of the tanks is achieved thanks to the advanced design and
structure of the ribs. The consistent quality of the product is ensured by the automatic
manufacturing method. SNIGO is designed to withstand the heavy ground loads without significant deformations. The tanks are groundwater-stable as well.
Telescopic shaft is designed to adjust the manhole cover flush with the ground surface. The adjustment is helping the cover to avoid becoming an obstacle by cutting the grass or by making the paving. The height of the shaft can be adjusted in the range of 200 mm. The shaft is designed for connection with standard polyethylene or cast iron covers for load classes from A15 to D400 according to standard EN 124.
Watertight to the ground surface
SNIGO is equipped with two special seals. The first seal is located between tank body and manhole shaft, the second seal is between the manhole dome and telescope. The seals ensure that no liquid droplet will penetrate into the tank or from the tank.
