Chlorination and Corrosion: Balancing Disinfection and Infrastructure Protection
At Pipe Testing Services (PTS), we understand the delicate balance between using chlorination for effective water disinfection and protecting the integrity of your water infrastructure. While chlorination is vital for killing harmful pathogens and maintaining water safety, it can sometimes accelerate corrosion in pipes and fittings.

In this comprehensive guide, we will explore how chlorination impacts infrastructure, the role of water chemistry, and how PTS applies advanced strategies to maintain both water safety and system longevity.
The Chlorination-Corrosion Conundrum
Chlorination is a widely used method for disinfecting water, but it comes with its own set of challenges. One of the key issues is its potential to cause corrosion in metal pipes, leading to infrastructure damage. Striking the right balance between effective chlorination and controlling corrosion is critical for water suppliers, facility managers, and industrial systems across the UK.
Key Factors Affecting Corrosion
Chlorine concentration
Higher levels of chlorine can increase the rate of corrosion, especially in metal pipes.
pH levels
Acidic or alkaline water can amplify the corrosive effects of chlorine.
Water temperature
Warm water tends to accelerate both disinfection and corrosion processes.
Pipe material
Metal pipes (copper, steel) are more susceptible to corrosion than plastic alternatives.
Water chemistry
Alkalinity, hardness, and other factors influence how water interacts with chlorine.
UK Regulatory Framework
In the UK, water treatment practices must comply with strict regulations to ensure both water quality and infrastructure protection. PTS ensures that all our services adhere to:
- The Water Supply (Water Quality) Regulations 2016
- Drinking Water Inspectorate (DWI) guidelines
- British Standards Institution (BSI) specifications
These regulations not only mandate safe chlorine levels but also require preventive measures to avoid long-term damage to water systems due to corrosion.
PTS's Innovative Approach to Chlorination and Corrosion Control
At PTS, we take a multi-faceted approach to balance disinfection with infrastructure protection. Our team uses advanced technology and specialised knowledge to manage the risks of corrosion while ensuring water safety.
Advanced Water Chemistry Analysis
Before chlorination, we conduct thorough water chemistry analysis to understand how chlorine might affect your pipes. This includes:
- Langelier Saturation Index (LSI) calculations to assess water’s scaling or corrosive potential.
- Aggressive Index (AI) monitoring to predict corrosive tendencies.
- Metal content analysis to determine vulnerability to corrosion.
Tailored Chlorination Strategies
We design customised chlorination plans based on your system’s unique needs. This ensures effective pathogen control without compromising pipe longevity. Our methods include:
- Precise dosing control systems that regulate chlorine levels.
- Alternative disinfection methods, such as UV or ozone, where chlorine might pose a corrosion risk.
- Chloramine treatment for systems prone to corrosion, offering a safer, long-term solution.
Corrosion Inhibition Techniques
Our expert team uses cutting-edge corrosion inhibitors and other methods to protect your pipes from damage. These include:
- Phosphate-based inhibitors to create a protective layer on metal pipes.
- pH adjustment to optimal levels that balance disinfection with corrosion control.
- Cathodic protection systems for metal infrastructure, providing an additional line of defence.
Continuous Monitoring and Adjustment
Maintaining the right balance of chlorination and corrosion control is an ongoing process. PTS offers real-time monitoring solutions, ensuring chlorine levels and water chemistry remain optimal. Our services include:
- Automated dosing systems that adjust chlorine levels based on real-time water quality data.
- Regular inspections to assess infrastructure condition and prevent potential issues.
Material-Specific Solutions
Different pipe materials respond differently to chlorination. At PTS, we tailor our approach to your system:
- Copper pipes: Adjust pH and alkalinity to form protective scales.
- Iron pipes: Implement strategies to stabilise protective oxide layers.
- Plastic pipes: Ensure chlorine levels don’t exceed material tolerances.
Environmental Considerations
At PTS, we prioritise sustainability. We strive to use eco-friendly materials and practices, ensuring that our chlorination services are safe for both public health and the environment. Our sustainable efforts include:
- Eco-friendly corrosion inhibitors to minimise the environmental impact.
- Precise chemical dosing to reduce unnecessary chemical usage.
- Responsible disposal of chemicals in compliance with environmental regulations.

FAQs on Chlorination and Corrosion
How does chlorination affect water infrastructure over time?
Chlorination can help control biofilm growth in pipes but may also accelerate corrosion, especially in metal pipes, if not properly managed.
What are the risks of inadequate chlorination?
Inadequate chlorination can lead to microbial growth, biofilms, and waterborne diseases like Legionella, posing significant public health risks.
How does PTS manage corrosion in chlorinated water systems?
PTS uses a combination of water chemistry analysis, corrosion inhibitors, and real-time monitoring to minimise corrosion while ensuring effective disinfection.
