Review of potential valve replacements for a UK water company

WRc investigated suitable replacement valves for a UK water company by assessing flow and pressure data, considering demand forecasts to ensure consistent supply to customers.

A UK-based Water Company

 The client is a water company based in the South of England, serving around 700,000 customers across an area of nearly 900 square kilometres.

The Challenge

WRc was engaged by a UK water company who was frequently encountering issues with their pressure reducing valves (PRVs), and one of the valves in their network had completely failed. The company called on WRc to urgently examine the water supply network in the affected zone and advise on a replacement valve.

The Solution

WRc assessed flow and pressure data to evaluate the suitability of potential pressure reducing valve replacements. The team also created a model to replicate the system and run simulations of the network, highlighting the location of critical pressure points, and showing the impact of using a booster upstream to reduce pressure. A peak day demand model was created to show the impacts of the potential valves on flow and pressure during periods of increased usage. 

The Outcome

WRc produced a comprehensive assessment of the two most suitable replacement valves, providing evidence from simulated scenarios and collected data in conjunction with expert knowledge. The report detailed the estimated cost and impact of the most beneficial replacement valve.
