Background
The water industry is facing increasing pressure to reduce per capita consumption and leakage levels. This means we can’t just focus on optimising new systems; we also need to get the most out of existing assets. Pressure management is key here, helping to drive down leakage, minimise bursts, and create smaller, pressure-monitored zones for better overall reporting and control. This proactive approach not only conserves valuable water resources but also enhances the longevity and efficiency of the entire network.

Enhanced resilience and efficiency
Our Approach
Our process begins with using hydraulic models to identify potential savings. We first verify these models against real-world data, including pressure, flow, and consumption, ensuring they accurately reflect current operations. This model validation establishes a precise baseline for detailed analysis.
Based on each water company’s specific minimum pressure requirements (for customer service and firefighting), we optimise zonal pressures. For existing systems, this may involve adjusting current pressure regulating valves (PRVs) using strategies like fixed-outlet, time-modulated, or flow-modulated control. If new control is needed, our hydraulic modelling determines the optimal location and sizing for new assets such as PRVs, pressure sustaining valves (PSVs), or variable speed pumps.
We then assess various control options to maximise savings and performance. A key step is a thorough CAPEX and OPEX assessment for each proposed scheme, evaluating projected water and energy savings against investment costs to demonstrate a clear Return on Investment (ROI).
Beyond financial returns, optimising pressure significantly reduces bursts, leading to lower repair and maintenance costs, fewer customer disruptions, and extended asset life. A “calmer” network also reduces new leaks and improves system resilience, offering environmental benefits through water and energy conservation.
