What PROCESS FLOW LIMITED does
Process Flow Limited is a privately held New Zealand water infrastructure firm founded in 2009 by Managing Director Gary Smith and headquartered in Richmond, with a manufacturing workshop in Nelson. The company designs, project manages, and constructs water treatment plants, reservoirs, pump stations, and modular infrastructure for municipal councils and selected industrial clients, with all work delivered to comply with the Drinking Water Standards New Zealand (DWSNZ). Its portfolio spans small-scale upgrades (~$110K) up to multi-million-dollar plants, including a $4.5M coal seam gas wastewater facility for Queensland Gas Corporation in Australia.
The company's core technology stack combines conventional treatment processes — membrane filtration, ion exchange, reverse osmosis, UV disinfection, chlorination, and pH adjustment — with a differentiated modular transportable plant model. Modular buildings are fully assembled and pre-commissioned at the Nelson workshop before being transported to site, materially reducing on-site construction hours (e.g., Collingwood completed in under 20 site days). Product lines are organized into three categories: Water Infrastructure Projects (full design/build for municipal water assets), Modular Transportable Plants (pre-fabricated buildings for remote or constrained sites), and Water Filling Stations (community-scale water dispensing units).
Process Flow generates revenue through one-off project-based contracts and professional engineering services, with no recurring subscription or licensing model. Customers are almost entirely New Zealand district councils — Tasman, Grey, Buller, and Westland — plus a single disclosed industrial customer in Australia. The company sells directly via enterprise field sales, leveraging founder relationships, vendor-independent technology recommendations, and repeat procurement wins. The firm operates with a small team (1-10 employees) and has not raised external capital.

PROCESS FLOW LIMITED competitors and assessment
Company assessmentBroad incumbents
- Veolia Water Technologies & Solutions: Global water treatment technology and services provider offering DWSNZ-compliant plant designs, mobile/Modular plants, and full EPC delivery. Operates in NZ/AU and competes for the same municipal upgrade opportunities as Process Flow, but at vastly greater scale and with a full product portfolio.
- SUEZ Water Technologies & Solutions: Global water and wastewater treatment OEM/services provider with packaged/Modular drinking water plants. Comparable to Process Flow on treatment technology and membrane/UV/RO offering, but with multinational scale and a global reference base.
- Downer Group: Major ANZ infrastructure services and water utility contractor delivering treatment plants, pipelines, and operations. Competes with Process Flow for council capital programs across NZ and Australia under multi-year framework agreements.
- McConnell Dowell: Australia/NZ infrastructure contractor with strong water pipeline and treatment plant capability. Comparable as a competing design/build partner for NZ and Australian municipal water projects, but operating at materially larger project scale.
- Stantec: Global design and engineering consultancy with significant water treatment and infrastructure practice in ANZ. Comparable on the design and PM components of Process Flow's design/build offering, though typically not a modular plant fabricator.
- WSP: Global professional services firm with large ANZ water practice covering planning, design, and PM for treatment plants and pipelines. Comparable as a competitor/partner for the engineering design elements underlying Process Flow's design/build offerings.
- Fulton Hogan: ANZ civil infrastructure contractor with growing water treatment and pipeline capability. Comparable on the civil/structural and pipeline delivery elements of Process Flow's scope across NZ councils.
Regional players
- Tonkin + Taylor: NZ-headquartered environmental and engineering consultancy with strong water treatment and infrastructure design practice. Comparable as a specialized NZ/AU firm offering design-side support for DWSNZ-compliant water projects, often as a partner or competitor to Process Flow.
Emerging players
- Hidrostal: Pump and packaged pumping systems provider active in NZ/AU water and wastewater. Comparable as an adjacent supplier for pump stations (e.g., Pomona Road Pump Station) within Process Flow's modular plant offerings.
Direct peers
- H2OPE Systems: New Zealand water treatment specialist serving municipal and rural drinking water clients. Directly comparable as a small NZ-focused DWSNZ-aligned treatment plant builder competing for the same council pipeline as Process Flow.
