Effluent Systems

What to do with the effluent and waste produced by the herd is a common problem that all dairy farms suffer from. Effluent disposal is an important farm activity but it doesn’t need to be costly and time consuming. The correct collection, storage, treatment and distribution of effluent will result in real benefits for your pasture and your pocket.

If you have and well designed effluent system that manages and deals with waste effectively you will have few problems. However, if your effluent systems are not correct or are outdated you could well be looking at reduced income, health issues or even heavy fines.

There are many different systems available for dealing with effluent and all have their pros and cons. That’s where getting the right advice before construction starts is invaluable.

Don Chapman Waikato are specialists in farm effluent systems and can design and construct a range of treatment options to suit your particular requirements.

Effluent treatment system options

Weeping Walls

Shed and yard water flow into a bunker with a weeping wall, which holds back up to 80% of the solids. The Chapman DairyTM  weeping wall design is a well-engineered solution for extremely efficient and economical management of solids. The wall and containment area is divided into two sides. Only one of the two sides is used at a time, allowing solids in the other side to dry. Dry solids can then be safely spread onto the land as zero-cost fertilizer.

Effluent bunkers / pumping sumps

These can be constructed to any size depending on farm requirements. Effluent bunkers are usually used after a stone trap or weeping wall to pump effluent to a pond or spray applicator.

Slope screens or rotating drum separators

We can either just construct the necessary concrete structures and drying areas, or manage the entire effluent separation stage. The choice is yours.

Sand wedges / traps

Farmers often find that precast sand traps are too small for the job at hand, typically requiring emptying several times per week. This is time consuming and is often not done, allowing solids to pass through the effluent trap when it’s full. Because Chapman Dairy sand wedges and traps are custom designed to a size that meets your needs exactly, they may only need emptying monthly or even less frequently.
