A Waihi and Te Moana catchment group field day, later this week, will focus on optimising water use.
The field day, to take place on Saturday, will focus on how a deer farm and a food processing plant use and conserve water.
Spokesman Rhys Taylor said the event would showcase how water access and behaviour among deer herds could be best-managed to reduce silt loss from the paddocks.
The name of the farm to be used for the workshop had not been released to prevent people from turning up if they had not registered prior to the event, Mr Taylor said.
A wetland area, fenced off from farming activity to allow native plant species to recover, will also be showcased on the day.
