Innovation Our Challenges Our Water Challenges

Catchment Area - First line of defence

We know that the quality of the raw water we use to prepare drinking water is affected by the activities that take place within the catchment – that is the area that surrounds local watercourses. That is why catchment management has now become the first step of our treatment process, so that we can start with the best quality of water possible.

We are looking for solutions to:

  • Help treat algae and prevent algal blooms in reservoirs
  • Reduce Natural Organic Matter (NOM) in upland streams
  • Environmental and asset monitoring

Treatment - Safe, reliable and efficient

Our Treatment processes are well established but we aim to continue to improve the efficiency of our works.

We are looking for:

  • Disinfection by-products (DBPs) removal or prevention
  • Effective treatment to stabilise and deliver non-corrosive water to Distribution
  • Chemical free treatment
  • Predictive tools to allow us to prevent no-water outages
  • Solutions to prevent waste discharges to the environment from Water Treatment Works
  • Chemical free treatment processes
  • Sludge treatment and disposal
  • Taste and Odour removal
  • Low energy alternatives to UV

Distribution Area - SMART, reliable and right

Water Quality

Nothing is more important than high quality and safe drinking water. The quality of our tap water is amongst the best in the world, we know this because we analyse almost 300,000 samples every year.

We are looking for:

  • New innovative monitoring systems which will allow us to continuously monitor key water quality parameters
  • Water mains cleansing technology
  • Treatment strategies to keep Disinfection By-Products as low as possible


Water is our most valuable resource so we must continue to do all we can to ensure we don’t waste it.

We are looking for:

  • SMART metering technology


We distribute water to more than 3 million customers across Wales, parts of Deeside and Herefordshire. We’re looking to improve the efficiency of our distribution systems.

We are looking for:

  • Automated Strategic Distribution System Control, having the ability to transfer water without manual or field intervention
  • Online monitoring for chemical and physical parameters
  • Asset maintenance techniques including SRV’s and trunk mains
  • Hydroturbine technologies for clean water mains

Improving services for our customers

We know how inconvenient it is for our customers when they lose their water supply, even for a short amount of time. We must ensure we can continue to provide the highest quality drinking water to meet our customer’s expectations.

We are looking for:

  • Predictive alarms which can detect rates of change, diagnostics and intelligent system analysis
  • Technologies to ensure that customer’s expectations are met regarding water quality
