Streamlining the process of supplying water and wastewater treatment solutions

Safewater is our range of packaged water and wastewater treatment plants & processes.


Lutra have one of the largest and most experienced Process Engineering teams in New Zealand. Our expert team can design full scale & portable water and wastewater treatment plants to meet your needs.

Experienced with working on both Greenfield and Brownfield sites, our team can design and build an end-to-end plant, or an individual treatment process.



Our inhouse fabrication facility, located in Wellington New Zealand, turns our designs into reality, following strict quality assurance processes.

Built on skid's, all of our water treatment plants and wastewater treatment plants can be fabricated offsite, allowing site enabling works and civils can to be undertaken simultaneously, reducing timelines and improving health and safety outcomes.



Lutra are continually searching for water and wastewater technologies that will significantly improve the way in which treatment processes are undertaken in New Zealand.

Working outside of the box, Lutra have a range of pilot plants available that can be used to prove a unit process, prior to designing a full scale plant.

Wastewater Treatment Solutions

The MBBR (Moving Bed Biofilm Reactor) process is a biofilm process using carrier media inside a process tank to provide a very large surface area for microorganisms to grow and consume pollutants. The process can be aerobic, anoxic, or anaerobic and be used for organics removal and /or nitrification and denitrification. The treatment process only relies on the microorganisms growing on the media so there is no need to manage or control Solids Retention Time (SRT), Mixed Liquor Suspended Solids (MLSS), or F:M ratios.

Lutra's packaged MBBR wastewater treatment plant has been designed to meet the needs of New Zealand and this technology has been proven to perform extremely well internationally.
