When things are broken they need to be fixed fast. Engineers need to be deployed to site with the right IT equipment – laptop, software tools and leads to connect to the field controllers (PLCs) or site instrumentation. This enables them to find and fix the fault with no repeat visits or costly delays.

The Water Industry is part of the UK’s Critical National Infrastructure (CNI) and therefore there needs to be high standards of information security too.

Jeremy Bull, Z-Tech’s Technical Director developed an IT strategy that allows for the company’s rapid growth with rapid deployment whilst also delivering the highest standards of security. Using our private datacentres with virtualised desktop technology we can work anywhere that has a connection to the internet. The data is kept in our datacentre with the users accessing their Windows desktop remotely, but to them, it appears as if they are working on a PC on their desk.

Engineers need to connect to devices in the field as well as their virtualised desktop. Our field laptops therefore use full disk encryption along with two factor authentication to ensure that our customer data is always held safe and secure, and in accordance with our ISO27001 certification.

Deploying first class IT is key to enabling all of our staff to do their work, and a lot of work under the bonnet enables Z-Tech to react quickly to the benefit of our customers.

  • "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."
