Silage effluent tanks

What is a silage tank?

A silage tank is a sealed, single-chambered system that temporarily stores silage effluent underground. It is most often used in areas with impermeable soil, where waste cannot be discharged into the ground.

Silage effluent can be up to 250 times more polluting than domestic sewage. If surface runoff carries it into a watercourse, the consequences for aquatic ecosystems can be dire.

Our underground silage tanks offer a reliable solution. Made with glass-reinforced plastic (GRP), our corrosion-resistant tanks feature an internal protective liner that keeps silage effluent safely on site until it can be removed by a professional.

Example applications

  •     farms
  •     stables
  •     agricultural sites

How do our silage tanks work?

Our silage effluent tanks are watertight GRP tanks that store silage underground. There is no processing or treatment involved.

Similar to cesspools, they require regular emptying by a licensed waste disposal company and are usually used in areas where the discharge of effluent into the ground is not possible due to unsuitable soil conditions.

Our silage effluent tanks can be fitted with alarms to inform you when they require emptying.
