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/sub-grade 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 provides an impermeable barrier against a wide range of solids and liquids. Designed to withstand the harsh effects of nature, is chemical and UV resistant.
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.
Its storage is governed by various legislation, such as the SSAFO regulations and OSR Wales. Within the legislation it is required 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
Your slurry lagoon has an impermeable barrier between the stored slurry and the surrounding soil and water table
Traditionally, farmers have used an earth-baked base as a liner due to its low cost. The difficulty with this option, however, is that it needs to be checked for permeability and once installed it can be awkward to repair.
In contrast, lagoon liners provide a cost effective and compliant means to contain agricultural waste on farms.
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
