Z-Tech has experience in all EC&I aspects of the UK Water Industry. Our engineers are trained and highly skilled in working on a full range of projects from small plant upgrades through to major plant commissioning and maintenance.

Z-Tech Water Networks Business Unit:

We focus on installing and maintaining control and instrumentation equipment located within the “infrastructure” asset base of water utility companies.

Working for the majority of UK water companies, our specialisms include: flowmetering, pressure management, burst detection, data logging, telemetry and level instrumentation.

By adding mechanical and minor civil engineering skills to our core EC&I skillsets, we have developed highly efficient, cost effective and rapid turnaround “one-stop-shop” solutions such as next day installation of large diameter flow meters.

Our “Z-One” software tools are used by many of our customers to manage multi-contractor workflow, asset data and reporting on tens of thousands of their critical infrastructure assets


Z-Tech will help you with MAINTENANCE: 

Z-Tech serve the UK Water Utility and Power Generation sectors with a wide range of EC&I planned and reactive maintenance services.

Our expertise lies mainly in Instrumentation, LV electrical and PLC / SCADA systems and typical contracts range from site-based maintenance teams, which are usually on long-term framework agreements/contracts, through to mobile calibration teams, that tackling power station outage works or larger scale planned maintenance programmes of work.

We have a vast amount of knowledge in both the Water and Power generations sectors, broad skillsets and flexible and responsive teams. Our teams are highly trained and ready to hit the ground running with the very best tools and equipment – this includes a sizeable fleet of Beamex calibrators.


Z-TECH will help you with PROJECTS (PMO):

Z-Tech’s experienced projects team is structured for delivery of specialist C&I Projects.

The combination of APM trained Project Managers and highly skilled technical team mean we can deal with specialist systems installation and integration – with a combined experience to work on any PLC ever made!

With the back-up of the larger Z-Tech team, our Projects Business Unit can flex, and offers UK-wide coverage.


Z-TECH will help you with LABOUR:

Water, Power and Rail sectors in the UK continue to find it difficult to find skills around the specialist EC&I labour requirements.

At Z-Tech we have spent many years working on long-term strategies to address this problem, not only for ourselves but also to be able to provide skilled people to our customers.

This might be for something as short as covering for a spike in workload, sickness or for longer-term commitments, embedded in one of your teams.

As a general rule, if your skills shortage comes under the umbrella of things we do as a company, then we can help you out -typically this would be Industrial Maintenance Electricians, Fitters, C&I Technicians, Systems Engineers and Project Managers. 

If we supply you with one of our people, you get a lot more than just that individual – they come fully trained and equipped to hit the ground running and with the full support and backup of a control systems business specialist in your sector: van, tools, laptop, PPE, training and software.

Whatever is needed, we take care of it!
