What We Do

Independent water treatment support from planning through to delivery and operation.

We work with councils, communities, and water suppliers to identify and clarify risk, determine upgrade options, and support complex drinking water infrastructure decisions through to delivery.

Our work spans governance briefing and option assessment through to procurement support and delivery oversight. We also strengthen operational resilience through HACCP-based planning, contingency development, and practical operational documentation.

New Zealand Focus

Specialist advice for the way New Zealand water suppliers actually operate.

JK Process provides water treatment engineering in New Zealand with a practical focus on compliance, plant performance, and day-to-day operability. We support small and large supplies, conventional treatment plants, membrane systems, UV disinfection, chlorination, source water risk management, and treatment upgrade planning.

If you need support with Water Safety Plans, DWQAR interpretation, treatment design, HAZOP facilitation, HACCP planning, or response to a drinking water compliance event, our services and project experience show how we help suppliers across New Zealand move from risk identification to workable action.

Core Areas Of Focus

Technical advice grounded in compliance, process performance, and resilience.

Risk & Compliance Strategy

Identification of water safety risks, compliance gaps, and upgrade pathways. Governance briefings and regulatory interpretation where required.

Process & Treatment Design

Treatment configuration, control philosophy development, Basis of Design, PFDs, P&IDs, Safety in Design, and HAZOP facilitation.

Operational Resilience

HACCP plans and critical control point development, contingency and response planning, operator workshops, and post event investigation and improvement.
