PigBal is a tool to assist piggery planning and management by modelling waste outputs. It estimates waste outputs so that you can evaluate and design:  

  • Piggery management systems 
  • Sustainable reuse areas

It can also be used to estimate Greenhouse gas emissions (GHG).  

The latest version (PigBal_v4.099) was reviewed and revised in May 2018. Updates were made to improve the accuracy of manure and GHG predictions.  

You can download a copy of the model below.


WatBal can help you design your effluent system. It calculates a daily water balance on piggery effluent treatment and storage systems.
