Pesticide Handling Area Information

 

Research completed with a local farmer in the catchment, looking at pesticide run-off from the field and farm yard has shown that pesticide contamination from the farm yard contributes around 40% of pesticides found in watercourses and can be 100 times the 0.1ug/l Drinking Water Standard. 

 

The following options below are ways of mitigating against this by improving your sprayer filling area:

 

Biobeds

 

 

 

A biobed consists of a bunded, concrete sprayer filling area, which runs into a catchment tank.  The pesticide washings are then drip fed through a lined hole in the ground, filled with a mix of straw, soil and compost and turfed over.  This process effectively removes the pesticides from the water and the resultant water is irrigated onto a vegetated area.

Biofilters

 

Biofilters operate in the same way as a biobed as they contain the same biomix.  However, they are formed of a stack of three IBC’s.  The water from the bunded concrete pad is pumped to the top IBC and filters down through the three, before being irrigated to a vegetated area.  A biofilter can only treat 15,000 litres of pesticide washings a year – in this way, the concrete filling area will need to be covered in some way.

Roofed Sprayer Filling Area

 

It is also possible to roof your concrete, bunded sprayer filling area.  This will prevent any rainfall entering the system and therefore any drips, spills or splashes could be disposed through a licenced waste contractor or with on an Environmental Permitted area (formerly Groundwater Authorised Area).

 

Pesticide Container Drip Racks

 

 

There are many innovative ways of creating a drip rack for pesticide cans in order to ensure that any liquid is contained before it is fully dry.  Any liquid from this rack can then be disposed of through the biobed or biofilter.
