Water Pipe Flushing: Maintaining Clean and Safe Water Distribution Systems
Water pipe flushing is a crucial process for maintaining the quality and safety of water distribution systems. At PTS, we employ this method to clean and disinfect water pipes by forcing a high-velocity flow of water through them.
This important maintenance procedure helps prevent the build-up of sediments, biofilms, and other contaminants within the pipes, ensuring that customers receive clean and safe drinking water.
Our Services
At Pipe Testing Services (PTS), we recognise the importance of maintaining clean and safe water distribution systems. The build-up of sediments, biofilms, and other contaminants within water pipes can severely compromise water quality and pose health risks if left unchecked.
We pride ourselves on providing precise assessments and customised flushing strategies. By partnering with us, you can proactively safeguard the integrity of your water systems and ensure the delivery of high-quality water to your customers or end-users. If you require water pipe flushing services, feel free to reach out to our team of experts.

What is Water Pipe Flushing?
Flushing refers to the process of cleaning and disinfecting water distribution pipes by forcing a high-velocity flow of water through them. This technique is essential for water utilities and infrastructure companies. It helps maintain water quality and prevent the accumulation of contaminants within the pipes.

The Process
Our engineers carry out a detailed process, here’s the mains steps:
- Isolating Pipe Sections: Sections of the water main are isolated by closing valves to create a unidirectional flow.
- Opening Hydrants and Valves: Fire hydrants or blow-off valves are opened to allow water to flow at high velocities, typically above 1.5 m/s (5 ft/s), to scour the pipe walls.
- Dechlorination (Optional): The flushing water may be dechlorinated before discharge to reduce environmental impact.
- Monitoring and Completion: Flushing continues until the discharged water appears clear and meets turbidity or chlorine residual targets.
Water Pipe Flushing and Chlorination
Flushing is often combined with chlorination works, where chlorine is added to the water to disinfect the pipes and maintain a residual chlorine level throughout the distribution system.
The high-velocity aspect helps remove biofilms and sediments that can harbour bacteria and consume the chlorine residual. After flushing and chlorination, the pipes may need to be flushed again to remove the excess chlorine before returning the main to service.
Benefits of Water Pipe Flushing
Regular water pipe flushing offers several benefits, including:
- Improved Water Quality: Flushing removes sediments, biofilms, and other contaminants that can affect the taste, odour, and appearance of water.
- Enhanced Disinfection: Flushing helps ensure the effectiveness of disinfection processes, such as chlorination, by removing materials that can consume disinfectants.
- Reduced Corrosion: Removing sediments and biofilms can minimise corrosion within the water distribution system.
- Compliance with Regulations: Flushing helps water utilities comply with regulations and guidelines related to water quality and safety.
Applications of Water Pipe Flushing
The method is a critical maintenance practice across a wide range of water systems and infrastructure. Its applications extend to various sectors, including:
Municipal Water Distribution Systems
Regular flushing is essential for municipal water utilities to maintain the quality and safety of their distribution networks. It helps remove sediments, biofilms, and other contaminants that can accumulate over time, ensuring that customers receive clean drinking water.
Industrial Water Systems
Many industries rely on water for various processes, such as cooling, manufacturing, or production. Water pipe flushing is vital in these systems to prevent the build-up of scale, corrosion products, or other deposits that can impair system performance, efficiency, and product quality.
Commercial and Residential Buildings
In commercial and residential buildings, water pipe flushing is recommended after periods of stagnation, such as after renovations or extended vacancies. This practice helps flush out any contaminants that may have accumulated during the stagnation period, ensuring the delivery of fresh, high-quality water.
Healthcare Facilities
Water quality is of utmost importance in healthcare facilities, as it can directly impact patient safety. Combined with other water management strategies, helps mitigate the risk of waterborne pathogens, such as Legionella bacteria, from proliferating in the water distribution system.
Fire Protection Systems
Fire sprinkler systems and standpipe systems require periodic flushing to remove sediments, corrosion products, and other debris that can accumulate in the pipes. This practice ensures that the systems are ready to perform reliably in the event of a fire emergency.

Flushing - FAQS
How often should water pipe flushing be performed?
The frequency depends on various factors, such as the age and condition of the pipes, water quality, and local regulations. Generally, it is recommended to flush water mains at least annually or as determined by a comprehensive assessment.
Can water pipe flushing cause discoloured water?
Yes, it can temporarily cause discoloured water due to the disturbance of sediments within the pipes. However, this should subside once the flushing process is completed and the sediments have been removed.
Is water pipe flushing necessary after repairs or construction?
Yes, it is recommended to flush pipes after repairs or construction work to remove any debris or contaminants that may have entered the system during the process.
What are the environmental considerations during water pipe flushing?
This technique can result in large volumes of water being discharged, which may require dechlorination or other measures to minimise the environmental impact. Proper planning and adherence to regulations are necessary.
Can water pipe flushing be combined with other maintenance activities?
Flushing is often combined with other maintenance activities, such as chlorination, leak detection, and valve exercising, to optimise the overall efficiency of the process.
How can water utilities ensure the effectiveness of water pipe flushing?
To ensure the effectiveness of water pipe flushing, utilities should follow industry best practices, including proper planning, monitoring of water quality parameters, and maintaining accurate records of the flushing process.
