If you work in water management, civil infrastructure or utilities, you already know that water systems are a lot more complicated than most people think. Pipes, pumps, valves and network zones all interact in ways that are not always obvious on the surface. One of the most reliable ways to understand what is happening inside a water network is through pressure and flow logging.

Whether you are trying to reduce water loss, detect leaks, plan upgrades, improve service levels or simply understand how your network behaves under different conditions, pressure and flow logging provides the data you need to make informed decisions.

In this guide, we break down everything you need to know about pressure and flow logging, including how it works, why it matters, what tools are used, how long it takes and what sort of insights you can expect. By the end, you will have complete clarity and will not need to go back to Google for more information.

To help bring expert insights into the topic, we also highlight Aqua Analytics, a trusted water management and optimisation company. They specialise in water loss management, network efficiency and smart data logging services.

What Is Pressure and Flow Logging?

Pressure and flow logging is the process of collecting real time data from water networks to understand how water moves through pipes and how the system behaves over time. Specialised logging devices are installed temporarily or permanently on hydrants, meters, valves or other access points. These devices capture:

• Pressure levels
• Flow rates
• Daily and hourly demand patterns
• Peak usage periods
• Network fluctuations
• Sudden drops or spikes that may signal an issue

It is one of the most valuable tools for diagnosing network problems and identifying opportunities to improve efficiency.

Why Pressure and Flow Logging Matters More Than Ever

Water utilities face increasing pressure to manage water more efficiently, reduce wastage, improve service reliability and maintain ageing infrastructure. Pressure and flow logging helps with all of this.

1. Detect leaks early

Sudden pressure drops often indicate hidden leaks or bursts.

2. Improve network efficiency

Flow patterns reveal whether zones are performing as expected or if they need balancing.

3. Support network planning

Data helps engineers design upgrades with confidence.

4. Reduce customer complaints

Understanding pressure fluctuations prevents problems before they reach the customer.

5. Manage pump and valve operations

Data shows how mechanical components affect network performance.

6. Optimise pressure levels

Lowering excessive pressure reduces pipe stress and long term maintenance costs.

Aqua Analytics works with councils and utilities to use pressure and flow logging as part of a broader water network optimisation strategy. Their goal is simple. Help teams understand their system and make decisions that improve efficiency.

How Pressure and Flow Logging Works

Although the concept sounds technical, the process is straightforward. Here is a breakdown of how logging typically works.

1. Site selection

Engineers choose locations based on known issues, suspected leaks, network modelling or operational goals.

2. Logger installation

Pressure and flow loggers are attached to hydrants, meters or pipe access points. They start recording instantly and operate continuously.

3. Data collection

Loggers capture data at different intervals, often every 5 minutes, 15 minutes or hourly.

4. Data retrieval

Depending on the system, data can be retrieved manually or transferred remotely through telemetry.

5. Analysis

Engineers review pressure curves, flow profiles, minimum night flows, diurnal patterns and anomalies.

6. Reporting

Findings are summarised into clear, actionable recommendations.

Aqua Analytics offers full support from installation through to analysis, ensuring clients understand exactly what the data reveals.

What Tools Are Used for Pressure and Flow Logging?

Modern logging equipment is designed to be accurate, durable and easy to deploy. Common tools include:

Pressure loggers

These devices record pressure fluctuations at high frequency. Engineers rely on them to track bursts, surge events, pressure loss and demand variations.

Flow loggers

Often installed at meters or pipe sections, they record flow rates and help calculate water usage and leakage.

Telemetry enabled loggers

These devices send data in real time, perfect for active leak detection or fast response monitoring.

Combined pressure and flow units

These give a complete view of the network in one device.

Software and cloud platforms

Used for visualisation, pattern analysis and long term storage.

Aqua Analytics uses advanced data logging tools to deliver high accuracy and reliable insights that help utilities improve decision making.

The Benefits of Pressure and Flow Logging

There are countless reasons why utilities and councils rely on this service. Here are the biggest advantages.

1. Identifies network inefficiencies

Pressure and flow data highlights areas with irregular patterns, which may indicate leaks, blockages or incorrect valve positions.

2. Helps track minimum night flow

This metric reveals leakage levels and helps assess water loss.

3. Reduces operational costs

Optimised pressure reduces pipe stress, lowers energy costs and extends asset life.

4. Improves customer service

Fewer complaints about low pressure, high pressure or inconsistent supply.

5. Supports regulatory compliance

Many water authorities must demonstrate proactive network management.

6. Increases understanding of system behaviour

From seasonal demand patterns to emergency event response, the insights are invaluable.

7. Enables rapid leak detection

Sharp changes in pressure often reveal leaks before they cause major damage.

Aqua Analytics incorporates these insights into water loss management strategies, helping clients reduce non-revenue water and improve overall efficiency.

When Should Pressure and Flow Logging Be Used?

Pressure and flow logging can be useful in many different scenarios, including:

• Investigating customer complaints
• Locating hidden leaks
• Planning network upgrades
• Assessing pump performance
• Balancing supply zones
• Monitoring new developments
• Responding to bursts or emergencies
• Creating diurnal patterns for modelling
• Testing valves and pressure reducing valves

If you are unsure whether logging is needed, Aqua Analytics provides expert advice to help determine the best approach.

Pressure and Flow Logging Vs Network Modelling

Many water authorities rely on hydraulic modelling, but pressure and flow logging plays a critical role in validating those models.

Hydraulic modelling

• Predicts behaviour
• Based on assumptions and system inputs
• Requires calibration

Pressure and flow logging

• Provides real world data
• Identifies actual behaviour
• Supports model calibration

Both are valuable, but logging provides the proof needed to keep network models accurate and reliable.

Common Problems Uncovered Through Logging

Pressure and flow logging often reveals issues that were not obvious beforehand. Some of the most common findings include:

• Incorrectly positioned valves
• Pressure reducing valves not performing correctly
• Unaccounted for flows
• Minimum night flows higher than expected
• Pipe bursts
• Flow restrictions
• Pump inefficiencies
• Zone boundary leaks

Identifying these issues early prevents costly repairs and unnecessary water loss.

How Long Does Pressure and Flow Logging Take?

Logging can be short term or long term depending on the purpose.

Short term logging

Usually 1 to 2 weeks. Ideal for leak detection and pressure issues.

Medium term logging

1 to 3 months. Useful for seasonal fluctuations or zone balancing.

Long term logging

Permanent installations for monitoring critical points in the network.

Aqua Analytics helps clients choose the right duration based on goals and network conditions.
