Take the guess work out of designing your effluent system, talk to the team at Waikato Milking Systems.

Farmers struggling to understand effluent regulations will be able to see a clearer picture of what’s required at this year’s Effluent and Environmental Expo at Mystery Creek near Hamilton.

Waikato Milking Systems Dairy Effluent Consultant Samantha Bull said ensuring dairy farms are compliant with regional council rules is paramount.

“But it can be confusing, compliance rules differ from region to region. And there are so many options out there in terms of equipment choices, it can be difficult to decide what’s best,” Samantha said.

Samantha will be part of the Waikato Milking Systems team which will be at expo to pass on expert advice to farmers, from November 19-20.

The company will have a range of pumps, stirrers, separators, irrigation and storage systems for farmers to learn more about.

“The great thing about the expo is that it’ll give people a chance to have a chat with us to see what’s going to work on their property.

“Waikato Milking Systems has Farm Dairy Effluent System Design Accreditation, which means we can visit farms and design a system that takes into account the rules and regulations set out by regional councils.”

Climate conditions, contour of the land, cow numbers, soil composition and farm management are also some of the points to consider when designing a new effluent system.

All could vary from property to property, which is why it’s important to customise each effluent system to match the unique conditions of a farm, Sam explained.

She said understanding soil types is important. 

“Soils that are classified as high risk will increase storage requirements as there are fewer days available to irrigate. Application of dairy effluent can only take place when a soil water deficit exists.

“This is compared to low risk soils where the application of dairy effluent can generally occur 24 hours post saturation, therefore there will be more days available for irrigation in any one year.” 

Farm management regimes can also have an impact on the type of effluent system needed.

“You have to look at how the farm dairy is managed, for example, some farmers may stand cows on a feedpad, how long the cows are on the yard during milking, whether the farmer is using storm water diversion or not.”

Reducing or recycling water can also be a way to reduce effluent storage requirements.

“Some farmers are a bit surprised when you show them how much water they are using, and how big their storage needs to be to accommodate for their water use.”

Samantha said farmers should contact their local regional council if they’re unsure what their dairy effluent systems need to be complaint.

“People can also speak to Dairy NZ, there are discussion groups they can join or they talk to people like us at Waikato Milking Systems, who are effluent specialists.

“Come and speak with us at the Effluent and Environmental Expo, see how we can help you improve your current system.”
