We have been involved in the design and maintenance of some of New Zealand’s large scale aquariums and enclosures.

Industrial Water Treatment
We have maintained and improved several industrial water treatment plants with clients who are required to meet trade waste consent limits for their facilities along with construction sites who are discharging contaminated construction site run off.
These plants fall into several areas and often a combination:
pH Correction
Facilities which undertake Cleaning in Place (CIP) often have waste water with a pH above or below their discharge consent levels, as such some adjustment is required prior to discharge. These systems often need regular maintenance from instrument maintenance and calibrations through to monitoring of correction chemical levels. As local water authorities can often enforce large fines on facilities discharging outside of their consent levels it is important to ensure that these systems are operating correctly. We have many year of experience with optimising pH correction facilities to reduce chemical and running costs, if you have a pH correction plant or need such a plant then call us to discuss your needs.
Heavy Metal reduction
We have assisted clients over the years build and maintain plants to reduce heavy metal contaminants in their waste water to meet discharge consents. These same problems can also be present with some clients using ground or bore water to supply their facilities. The most common contaminants can include:
- Iron – causing staining
- Manganese
- Zinc
- Chromium
Similar to water pH often heavy metal levels can form part of discharge consent conditions or can be a requirement for using the water for processing. Often metal levels can be difficult to reduce however we have experience in several processes that have proven to be cost effective and reliable for our clients.
We have experience in many different areas of water treatment in NZ and also in Australia, in many different areas of industry, if you are considering any of the following processes or have any of the applications listed below then please feel free to contact us.

Aquarium Design
We have been involved in the design and maintenance of some of New Zealand’s large scale aquariums and enclosures.
The Auckland Zoo Sealion enclosure and the Wellington Zoo Hospital salt water pool are two facilities our staff have been involved with prior to them being built.

Hospitals and Laboratories
Hospitals and Laboratories
We have installed and maintained several Reverse Osmosis (RO) systems in Hospitals in Auckland, these have primarily been used for supplying water to Laboratories and instrument cleaning machines.
Common uses for RO water in Hospitals and Laboratories.•Water for analyser equipment referencing solutions.
- Contaminant free cleaning water.
- Water Supply for hospital instrument and equipment washers to reduce or eliminate scale build-up.
- Boiler water for small scale hospital boilers.
What is Reverse Osmosis (RO) ?
Municipal Pool Water Services
Typically our large scale design projects are completed in autocad in 3D, this reduces the construction time on site and also reduces clashes with other services. As can be seen from some of the examples entire pool complexes can be modelled and checked prior to installation beginning on site.
