20000 Litre Shallow Dig Silage Effluent Tank – GRAF Platin XXL
Product code
From £6,666.49 Exc VAT (£7,999.79 Inc VAT)
Product Description
The 20000 Litre Shallow Dig Silage Effluent Tank from GRAF is the first Platin XXL silage tank, giving large storage in a tank that stays close to the surface.
Like all Platin tanks, the 20000 litre shallow dig silage effluent tank is wide and flat rather than tall. The tank body is just 1300 mm high, which keeps the excavation shallow, cuts digging costs and makes it a strong choice where the water table is high. GRAF designs Platin tanks to stay stable in groundwater, and the tough polyethylene body is far lighter than concrete.
Silage effluent is highly polluting and acidic, so it must go into a sealed tank rather than soak away. Polyethylene will not corrode in silage liquor, and the tank also suits dirty water from yards and parlours.

Sizing a 20000 Litre Shallow Dig Silage Effluent Tank
In England, SSAFO rules ask for at least 20 litres of effluent tank capacity for each cubic metre of silo, up to 1,500 cubic metres. On that basis a 20000 litre silage effluent tank covers a silo of up to around 1,000 cubic metres.
Scotland, Wales and Northern Ireland have similar rules, and below-ground tanks must stay watertight for at least 20 years. Speak to us if you need the manufacturer paperwork for the Environment Agency or your local regulator.
