Pre-Commission Cleaning of Pipework Systems
When it comes to installing or refurbishing pipework, ensuring a clean start is crucial. For industries, landlords, and facilities managers, pre-commission cleaning of pipework systems is not just best practice—it’s essential to prevent contamination, reduce maintenance costs, and protect against harmful bacteria like Legionella.
Here, we’ll discuss why pre-commission cleaning is a necessity, how it’s conducted, and the long-term benefits it provides. At Pipe Testing Services (PTS), we offer specialised pre-commission cleaning solutions and related services, setting the foundation for safe, efficient water systems.
What is Pre-Commission Cleaning?
Pre-commission cleaning is the process of thoroughly cleaning and flushing new or renovated pipework systems before they go into service. This initial cleaning removes contaminants, such as construction debris, oils, greases, and biofilms, which can support microbial growth if left unchecked. By starting with a clean system, you ensure optimal water quality and compliance with industry regulations.
Why is Pre-Commission Cleaning Important?
- Legionella Prevention: Legionella bacteria thrive in stagnant water and biofilms. Pre-commission cleaning removes these ideal breeding grounds, helping to mitigate the risk of Legionnaires’ disease.
- Improved Water Quality: Cleaning ensures that contaminants do not compromise water quality from the start, setting the system up for better long-term performance.
- Regulatory Compliance: In the UK, regulations such as BSRIA BG 29/2020 specify guidelines for the cleaning of closed-circuit heating and chilled water systems, ensuring a consistent standard across projects.
The Process of Pre-Commission Cleaning
Each pre-commission cleaning is tailored to the specific system, but most procedures include the following key steps:
System Assessment and Planning
A thorough inspection helps identify any potential problem areas in the pipework, as well as the materials used. This planning stage allows our technicians to customise the cleaning approach for maximum effectiveness.
Initial Flushing and Debris Removal
Before introducing cleaning chemicals, high-velocity flushing is used to remove loose debris from the system. This process ensures that any construction dust, metal fragments, or other materials are cleared.
Chemical Cleaning and Biocide Treatment
Once flushed, specialised cleaning chemicals are circulated through the system. These chemicals break down contaminants, dissolve biofilms, and remove scale deposits. In addition, biocides are applied to eliminate any remaining microbial contamination, which is particularly important for Legionella prevention.
High-Velocity Flushing and Neutralisation
After chemical treatment, a high-velocity flush is used to remove the dislodged contaminants and chemicals from the system. Neutralising agents are also used to ensure that any remaining residues do not impact water quality or system materials.
Corrosion Inhibitor Application
To prevent corrosion, we apply inhibitors that coat the interior of the pipes, extending the system’s lifespan and reducing the likelihood of premature breakdowns.
Final Water Quality Testing and Documentation
Once cleaning is complete, water quality tests are performed to confirm that the system meets required standards. Comprehensive documentation is provided, ensuring full traceability and regulatory compliance.
Industries That Benefit from Pre-Commission Cleaning
Pre-commission cleaning is essential across various industries, including:
- Commercial Buildings: Office buildings, shopping centres, and other large commercial properties benefit from initial cleaning to maintain water quality and meet health standards.
- Healthcare Facilities: Hospitals and clinics need clean systems to protect vulnerable patients from waterborne bacteria.
- Manufacturing and Industrial Plants: Large-scale water systems in industrial settings require thorough cleaning to prevent blockages, corrosion, and microbial growth.
- Landlords and Property Managers: Residential properties also benefit from clean systems, reducing maintenance costs and ensuring safe water for tenants.
Challenges in Industrial Settings
Industrial pipework systems, such as those found in manufacturing plants, often require advanced techniques due to complex layouts and high system demands. High-velocity flushing and biocide treatments need to be carefully balanced to avoid operational disruptions.
Our team at PTS brings specialised knowledge, advanced equipment, and regulatory expertise to manage these challenges effectively.

- Regulatory Compliance: Adhering to industry standards helps avoid legal and financial risks associated with unclean water systems.
Consequences of Skipping Pre-Commission Cleaning
Failing to clean a new or renovated pipework system can lead to costly issues:
- Increased Corrosion: Contaminants can accelerate wear, leading to leaks and costly repairs.
- Reduced Energy Efficiency: Blockages and scale hinder performance, resulting in higher operational costs.
- Legionella Risks: Biofilms support Legionella growth, raising health risks and potential liability.
- System Blockages: Debris can cause costly blockages, impacting performance and requiring repairs.

Pre-Commission Cleaning of Pipework Systems - FAQs
What is the purpose of pre-commission cleaning?
Pre-commission cleaning removes contaminants from newly installed or renovated pipework systems, ensuring that water quality is maintained and reducing the risk of microbial growth, such as Legionella.
How often should pre-commission cleaning be performed?
It’s a one-time process typically conducted before the system is put into service, after any major renovations or system changes.
Is pre-commission cleaning required by law?
In the UK, pre-commission cleaning isn’t legally required but is recommended to meet compliance with industry standards like BSRIA BG 29/2020 for closed-circuit systems.
