Villa Maria have engaged Apex Environmental to deliver a membrane bioreactor (MBR) wastewater treatment plant for their new Te Awa winery for vintage 2018.  Site construction is underway and the wastewater treatment plant must be ready by mid-February for the start of vintage.

Apex has been trusted with securing resources consents, and designing, building and commissioning the plant, based on its extensive experience installing MBR systems for wineries including Mt Difficulty, Spring Creek Vintners and Yealands.  With the discharge of treated wastewater occurring over an unconfined aquifer, a very high level of treatment is required, particularly noting the recent water supply contamination event in Havelock North that had major public health consequences.  A number of affected parties had to be satisfied with the proposed treatment plant and irrigation system before consent could be granted.

With a fixed deadline in place, a number of initiatives will be used to expedite completion of the works, including skid mounting and pre-testing large parts of the mechanical and electrical works and seeding the plant to reduce the time required for process start up.  The plant will also allow for the easy addition of a reverse osmosis unit that will take the treated wastewater from bathing quality to potable standard.
