Labour supply

Z-Tech’s labour supply department provide many types of resource to water companies throughout the UK who work on both sewage and drinking water sites.

We can supply Operators, Pipe Fitters, Electricians, Control and Instrumentation Technicians and Systems Engineers from our core team to assist with maintenance and projects of any size.  Our Technicians and Engineers are highly trained, qualified and have excellent experience within the industry. We can supply specialist labour to provide a solution to any short or long term situation.

Z-Tech work with Beamex Calibration equipment

Z-Tech work with Beamex, a leading company for providing calibration equipment for   calibrating your onsite assets. We are able to make Beamex affordable for smaller sites: as well as reducing the costs of the system, our highly trained calibration technicians remove the need for in house training.
We are using Beamex Mc5 and Mc6 Multifunction calibrators on site to accurately calibrate instrumentation; we then upload this to the Beamex Software Centre for reporting and tracking assets. In turn this will provide condition status of assets and predict possible failure/replacement. Please contact us for more information. 


Z-Tech understands the demands on the water utility sector to continuously operate to ensure customer satisfaction, meet environmental targets and ensure demands are met.

Where there is waste, there is a hazardous area. Whether it be a remote sewage pumping station or a large inner city sewage treatment works each and every inspection, remedial or installation, we carry out is completed to the highest of standards.

Some existing water treatment sites still use and store large quantities of chemicals for process purposes, as do COMAH sites. At Z-Tech, this is something we are more than capable to attend to, ensuring we have specialist gas monitors and equipment each and every time.

We work with our clients to ensure we can complete our inspections with the minimal of disruptions to the working environment and, should a shut-down be required, we assist and plan in advance to enable our client to reschedule or divert operations elsewhere.

In addition to inspections, we also carry out remedial works, whether on the spot repairs or replacements or as packages of works. We are happy to attend to remedials following other inspections companies. After each and every remedial or installation of equipment we complete a detailed initial inspection to certificate and verify our works. Find out more about ATEX.

"The customer focus and flexibility of Z-Tech makes it easy for a water utility to deal with. When we have a large and complex programme to deliver, planning every detail can be a challenge. Working with Z-Tech means that we can maintain delivery, knowing that resources are available to pick up the loose ends."
