Apex Environmental specialises in the design and build of bespoke water and wastewater treatment plants of all sizes throughout New Zealand, solving the challenges often thrown up by remote locations, having to integrate works into existing facilities and the unique environmental circumstances of each site.

The company, which is a Citycare Water subsidiary, works with industrial and municipal clients and has delivered projects in the food and beverage, dairy and winery sectors as well as for councils.

Constant adoption of new technology for sustainable and healthier outcomes is a key part of Apex Environmental’s mantra.

An example of this is a fat, oil and grease skimmer, The GreasebusterTM, which enables the continuous removal of fat, oil and grease using a hydrophilic belt.

Apex Environmental has recently installed this skimmer for the first time in New Zealand in a wastewater treatment process for a food processor.

Once extracted, grease and oil can be disposed of properly or re-used.

“It’s great to see the continuous introduction of new technologies for improved environmental outcomes,” Citycare Water Chief Executive Tim Gibson says.  

“Water quality is at the heart of Citycare Water’s work and we are pleased to share this passion with the team at Apex Environmental by supporting them in providing smart and adaptable water treatment solutions for our communities.

“The team at Apex Environmental is expanding and delivering their expertise into a variety of projects across New Zealand,” Tim says. 

Apex Environmental projects underway currently include industrial and municipal water and wastewater treatment plants.

These include a membrane bioreactor wastewater treatment plant for Watercare Meremere; one sequencing batch reactor wastewater treatment plant for Cardrona Valley Wastewater and Queenstown Lakes District Council and another for Whakatohea Mussels Ltd; an activated sludge wastewater treatment plant for NZSki at Coronet Peak; and a water treatment plant for Tasman District Council at Motueka.
