How to get further design advice

Further design advice is available on how to size the loading and washdown area and holding tanks and on pesticide washing volume calculations, from Catchment Sensitive Farming and in the Biobed Manual on the Voluntary Initiative website.

How to choose a location

The item should be constructed in an area set aside for pesticide loading and washing operations where there is no other traffic.

It can be constructed on the same area as the following features, even though they are ineligible for the Basic Payment Scheme:

  • farmyards
  • areas of land, or farm buildings, not used for production

What to do with pesticide washings

The pesticide washings collected in the holding tank should be pumped before the tank reaches capacity using a pump float switch.To dispose of the washings transfer them to a biobed or biofilter for treatment (a T32 waste exemption will be required for this). Alternatively, pesticide washings can be disposed of via a registered waste carrier to a suitably permitted disposal site or to a permitted area approved by the Environment Agency on the farm.

How to main the slab, bund and pumps

The concrete slab and bund regularly and repair any damage or deterioration. The pumps will also need to be checked regularly to make sure they are operating properly.

Also ensure that:

  • the area is not used for any purpose other than pesticide handling operations
  • the concrete in not damaged so that the area becomes impermeable
  • the storage tank does not overflow

More information about pesticide handling areas, biobeds and biofilters, including sizing and volume calculations, is available from the Voluntary Initiative.
