The 16000 Litre Silage Effluent Tank from GRAF is the entry size in the Carat XXL range. It is designed for dairy and beef farms with a large clamp, where effluent volumes in the first days after filling can be substantial.
Silage effluent is highly polluting and acidic, so it must be collected in a sealed tank rather than allowed to soak away. The 16000 litre silage effluent tank is made from tough polyethylene that resists the acid in silage liquor, and it can also be used for dirty water from yards and parlours.
Key Features
- 16,000 litre capacity (approx. 3,520 gallons)
- Sealed tank for silage effluent, slurry and dirty water
- Tough, lightweight GRAF Carat XXL polyethylene construction
- Polyethylene will not corrode in acidic silage liquor
- Maxi telescopic dome shaft with 150kg pedestrian lid as standard
- Optional 3.5 tonne traffic lid for yards and tractor routes
- 15 year manufacturer warranty and 50 year design life
Sizing a 16000 Litre 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 16000 litre silage effluent tank covers a silo of up to around 800 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.
