Dealing with Effluent Issues Post Canterbury Windstorm

Step 1: Be open and honest

  • Inform Regional Council and Milk company
  • Record everything you do
  • Inform staff of new practices and monitor carefully to ensure changes bed in
  • Draft a plan to avoid this problem in the future – share it with everyone

Step 2: Focus on minimising effluent generation

  • Make sure cows are calm coming to the shed
  • Hold them in the yard for the shortest time and keep them calm while there. Keep dogs well away
  • Scrape the yard and stockpile in a secure place or apply back to paddocks as a semi solid (watch loadings)
  • Be very careful with hoses, do not leave any hoses running when not in use
  • Do the minimum acceptable wash down
  • Divert any clean water away from the effluent collection system
  • Make sure all rain water is diverted away safely
  • Manage cooling water carefully, if possible divert any excess

Step 3: Maximise use of storage

Step 4: Apply responsibly

  • Most effluent is dilute and can be applied with a normal traveller – talk to a cropping neighbour
  • Check clean water irrigators frequently for signs of blockage
  • If using small orifice irrigators take extra care. Set intakes off the bottom of ponds to avoid solids blocking the system
  • Solids contain high levels of nutrients – take extra care in applying near waterways or on shallow soils
  • Discuss options to apply solids to crops instead of fertilisers – talk to neighbours
