Our Services
Water networks fail at pressure. DNS exists precisely at that point. For over 25 years we have designed, supplied, and installed transient prevention and network management systems that keep distribution networks stable, compliant, and operating. Our clients include Thames Water, Severn Trent, Yorkshire Water, Scottish Water, United Utilities, Anglian Water, and Affinity Water. Every service we offer is grounded in field-proven engineering and WRAS-approved products, not off-the-shelf solutions.
Services
What We Do
From initial transient surveys to full-system monitoring and bespoke equipment design, DNS delivers end-to-end solutions for water network management.
Transient Pressure Surveys
Full network transient logging, analysis, and risk-scoring. We identify surge events, their source, magnitude, and downstream impact.
Leakage Reduction
Combining pressure management with acoustic detection, DNS delivers measurable, sustained NRW improvement.
Network Monitoring
Continuous real-time monitoring using our proprietary data loggers and the DART platform — 24/7 visibility of your network’s health.
Pressure Management
Design, installation, and optimisation of PRVs, surge protection, and pressure control zones across your distribution network.
Asset Investigation
Root-cause analysis of recurring bursts, discolouration events, and air valve failures — delivering evidence-based remediation.
Consultancy & Training
Strategic advisory and hands-on training for water utility engineers on transient management, NRW strategy, and network resilience.
THE PROBLEMS WE FIX
What We Solve
Water networks face a relentless set of challenges. DNS was built to solve the toughest ones, the kind that drain budgets, disrupt supply, and frustrate network managers.
Transient Pressure Events
Sudden pressure spikes and surges that cause pipe bursts, joint failure, and asset damage — often invisible until it’s too late.
Persistent Leakage
Background leakage erodes NRW performance and wastes treated water. DNS’s tools locate and quantify it with precision.
Discolouration Complaints
Turbidity and sediment disturbance from pressure transients drives customer complaints and costly flushing programmes.
Supply Security Failures
Unplanned interruptions from burst events or valve failure put pressure on utilities to meet their regulatory commitments.
Energy Waste
Poorly regulated pressure means pumps work harder than necessary. Transient control reduces energy costs network-wide.
Air Valve & PRV Failure
Air valves and pressure reducing valves are frequently the source or casualty of transient events — DNS diagnoses and resolves both.
