What is slurry?

Slurry is a fantastic resource for farmers. Made from a mixture of manure and water, it’s a natural and nutritious fertiliser that helps grass and other crops to thrive. Some dairy farmers spread slurry onto the land; others inject it directly into the soil. It’s storage comes with many restrictions though.

What restrictions apply for the storage of slurry?

The storage of slurry in slurry pits and lagoons is governed by various legislation, such as the SSAFO regulations, NVZ and OSR Wales. The legislation requires that new or renovated slurry stores must have an expected life span of 20 years without maintenance for any part of the tank that sits underground.

It is essential that your slurry lagoon has an impermeable barrier between the stored slurry and the surrounding soil and water table. This is to prevent seepage that could contaminate the area.

Traditionally, farmers have used an earth-baked base as a liner due to its low cost. The problem with this though is that it needs to be checked for permeability and once installed it can be awkward to repair. The cost of repairs can often exceed the cost of a geomembrane installation.

How to store slurry?

Our Lagoon Liners provide a cost effective and compliant means to contain agricultural waste on farms until it is ready to be applied to the land as a fertiliser. We supply liners in a wide range of materials including Polyethylene , Polypropylene , Butyl rubber, Elvaloy & PVC in water and sewage projects. The material selected depends upon the chemicals, liquids and solids they have to contain. We can advise you on the best material for your specific application.

Soil/subgrade conditions should also be taken into consideration when choosing a membrane for a farm lagoon liner. The most commonly used membrane for slurry lagoons is a high-density polyethylene HDPE. This is due to its high strength and durability. This material provide an impermeable barrier against a wide range of solids and liquids. Designed to withstand the harsh effects of nature, is is chemical and UV resistant.

In summary, the benefits of using HDPE for farm slurry lagoons include:

  • Strong & durable
  • Puncture resistant
  • Withstands heat/cold weather fluctuations
  • High impermeability
  • Environmentally friendly

Why choose our slurry lagoons?

High strength & durability

Our geomembranes are designed to be strong and durable to ensure they last.

Puncture resistant

Our geomembranes are designed to have a high resistance to punctures, preventing root growth and other items puncturing the membrane and causing leakages.

Withstands heat/cold weather fluctuations

Our membranes are designed to withstand all fluctuations in weather from extreme heat to the freezing cold.

High impermeability, high yield and welded seam strengths

Our geomembranes provide an impermeable barrier against a wide range of solids and liquids. They also have excellent chemical and UV resistance, impermeability, and high yield and welded strengths.
