S&A Holden, Effluent Management System, Southland New Zealand

Opus was engaged by S&A Holden to provide services associated with the upgrade of their effluent management system, on their farm near Invercargill.  The client’s preference for effluent storage was an earthen pond (with geosynthetic clay liner) and a double weeping wall sludge bed as effluent treatment.  Our inputs into this project were undertaken in three phases: investigation and design, resource consents, and contract management and certification.

IPENZ Practice Note 21: Farm Dairy Effluent Pond Design and Construction, New Zealand

This industry leading IPENZ Practice Note was funded by DairyNZ and developed by an Opus team of specialist engineering and science professionals. It embodies the first industry-agreed set of good practice standards in the design and the construction of farm dairy effluent storage ponds in NZ. The practice note assists in addressing prevailing industry concerns about the environmental risks of poorly performing ponds by detailing good procedures and practices in the investigation, design and construction of new ponds. This practical reference document has been adopted by design engineers, contractors, suppliers and regional council staff. Click here for more information.
