The Dairy Effluent Storage Calculator is a software tool developed by DairyNZ and Massey University to determine the effluent storage requirements of a farm.

It works by looking at a farm’s inputs of soil risk in the effluent block, catchment areas, feedpads or barns and their use; wash water in the dairy, effluent irrigation depths, and the daily volume of effluent able to be irrigated.

The DESC then looks at 30 plus years of rainfall and evapotranspiration data from a local climate site, and from there it can calculate a daily soil water balance to determine how often effluent irrigation could occur, or if conditions are unsuitable how much effluent should be directed to storage.

This produces a graph showing the maximum storage volume required for each season over the past 30 plus years.
