Before you begin any work on your slurry tank, you should inform the environment agency at least 14 days before construction begins. You can do this by calling or writing to your local environment agency office. You will need the following information;
– Your name, address, telephone and email
– Details of the type of storage you wish to build or substantially change
– The exact location of your proposed storage, with the 8 figure grid reference
– A site plan drawing of the proposed structure
– A design plan, showing the design, specification, layout and materials to be used. You may also need to confirm that your design meets the requirements of BS 5502
– If you are planning to use prefabricated products, you should have a copy of the manufacturer’s specification guarantee
When calculating the capacity requirements of your slurry tank, you should include a minimum of 300 millimetres of freeboard. Your slurry tank should have the capacity for at least 4 months of slurry storage. This will depend on how much slurry you use, the size of your tank and the amount of rainfall.
If your slurry tank is fitted with a drainage pipe, it must have 2 valves that are separated by at least 1 metre. Each individual valve must be able to stop the flow of slurry and be locked when not in use. There is one exception to this if your slurry tank drains into another tank of equal or greater capacity.
Newly updated legislation that has recently come into force is the use of covers on newly built slurry tanks. As of February 2021 slurry stores and lagoons must be covered, unless an appropriate alternative is in place.
