Sustainable design
Optum Plumbing was engaged to install all plumbing, drain laying, heating, and solar work for Camp Glenorchy.
The camp’s goal is to use 50% less water and 50% less energy than standard accommodation facilities worldwide.
This project earned us the Project of the Year award at the NZ Plumbing Awards (2018).
Trusted by the best to work with the best














Kevin and the Optum team designed and built our first Solar Hot water system in Wanaka in 2010 and eleven years later it is still working faultlessly. Like all satisfied customers 10 years later we came back to the guru’s at Optum who provided us with invaluable advice for optimising a ‘no carbon’ solar hot water solution, to meet the underfloor and hot water requirements for our new SIPS panel passive house which we have built in Invercargill.
These guys are innovators and absolute experts in all aspects of service provision, are professional and are a pleasure to deal with. We have no hesitation in recommending them to other prospective customers and we look forward to working with them again on our next build.

Strategic Projects
We made the right choice using Optum for our plumbing. Our rural block and non-standard heating system were well designed and the team went above and beyond to fine-tune and have it working as we wanted. We learned that plumbing is not an area to cut costs and it really makes a difference having a team who are skilled and familiar with complex systems and new technologies. We would certainly use Optum again.

We had a complex build in Wanaka for our home.
Optum service was excellent and of the highest quality critical to the success of the build.
After completion when further extensions were planned also they were interested efficient and approachable in their service with a total professional standard.
Both Isabelle and I would highly recommend them to any person contemplating a build, extension or repair.

I did a big build out in Dalefield. I paid top dollar to get the best of everything. However, I used different suppliers and I ended up with a system that wasn’t integrated, was difficult to use, and just didn’t achieve what was promised.
I got Kevin and Optum involved and they took action to integrate everything and actually make it work.
If I’d had them involved from the start I’d have saved tens of thousands of dollars and I’d have gotten what I wanted.
Don’t make the mistake I did!
