A complete project provider, from design through to commission.

What we do

GFS have a tight design build team, skilled at packaging water or waste water treatment plants that result in economical, turnkey solutions for regional New Zealand.

The team utilises the most appropriate technology for the specific application and looks after all aspects of construction (mechanical, electrical, and civil), to deliver fully functional modular plants that are rugged and durable.

Solving Problems

GFS delivers simple solutions to complex problems.

If it involves water or waste water treatment, steel, or stainless-steel pipes, then GFS is the company to engage.

Working with you

GFS works directly with clients (such as local councils and industrial plant owners) that require substantive water or waste water solutions.

To maintain and control the quality and timing of the delivery, GFS prefers to self-perform all physical aspects of plant fabrication and installation. When working regionally, every effort is made to work with and support local businesses.

Keeping safe

GFS is a medium-sized company with big outputs. Health and Safety and Environmental considerations are front and centre of all work undertaken.

ISO accreditations held that support these priorities – ISO 9001, ISO 14001 and ISO 45001.

Products | Modular Treatment Plants

The EffBuster M is a tertiary wastewater filtration unit incorporating advanced membrane technology to remove suspended solids, E-coli, viruses and to lower BOD (Biochemical Oxygen Demand) and TSS (Total Suspended Solids), from wastewater flows. Membranes provide excellent removal rates; each unit is custom designed to suit the characteristics of the waste stream it is treating.

The fully self-contained unit comes with all pumps, valves, transfer pipes, tanks, electrical distribution, and a customised control system. It has a small footprint, with no need for major civil or construction work.

Membrane Bio-Reactor | Nitro Wastewater
Membrane Bio-Reactor | Nitro Wastewater

The EffBuster Nitro is a compact containerised biological treatment plant, using an advanced Membrane Bioreactor (MBR) waste water treatment system to remove nitrogen (N), ammonium (NH4+ ) and phosphorous (P). While still providing the same level of treatment as EffBuster M, for removal of BOD, TSS and E. Coli.

An easily transportable EffBuster Nitro pilot plant is available for customers to lease. It is suitable for a wide range of applications, including sewerage and industrial wastewater. The pilot option is often used to assess treatment needs and capabilities, prior to applying for consents for a permanent plant.

The ThirstResponder M is a containerised membrane filtration drinking water system, placed where it is needed. It is easily relocatable to alternative locations as required.

Each unit uses technologies most appropriate to treat the supply source including microfiltration (MF), ultrafiltration (UF) and reverse osmosis (RO), to make untreated water safe and pleasant to drink.

The fully engineered and designed modular system performs with maximum efficiency, even in harsh conditions. The high-quality components include all pumps, valves, transfer pipes, tanks, electrical distribution, and control systems.

The ThirstResponder UV is used for its strong germicidal inactivating ability to disinfect water containing bacteria and viruses. It is effective against protozoans like giardia lamblia cysts or cryptosporidium oocysts.

GFS supplies a range of NSF, ÖVGM and DVGW internationally certified UV disinfection containerised systems, ranging from small single lamp systems for small operations to large multi-lamp systems for municipal and industrial water treatment.
