What is Chlorination? The Foundation of Water Disinfection
Chlorination is a fundamental water treatment process involving the controlled addition of chlorine (or chlorine-based compounds) to water systems. This powerful disinfectant effectively eliminates harmful microorganisms, such as bacteria, viruses, and other pathogens, that can cause waterborne diseases. The primary benefits of professional chlorination services are numerous
- Pathogen Elimination: It safeguards public health by neutralizing dangerous contaminants.
- Biofilm Control: Chlorine helps break down and prevent the formation of biofilm, which can harbour bacteria within pipework.
- Odour and Taste Improvement: It can help in removing unpleasant odours and tastes from water.
- Regulatory Compliance: Ensures your water systems meet strict UK water quality standards, including guidance such as BS 8558 and the Water Supply (Water Quality) Regulations.
At Pipe Testing Services, our system chlorination procedures are designed to achieve thorough disinfection, preparing your water systems for safe use, whether for residential plumbing, commercial buildings, or municipal water supply networks.
Understanding Our Comprehensive Chlorination Services
Pipe Testing Services offers a wide array of specialised chlorination services to meet diverse client needs. Our expertise covers various scenarios, ensuring effective disinfection and compliance:
- New Pipework Installations: Essential for chlorination compliance in new construction projects, ensuring all new pipework is disinfected before connection to the mains supply.
- Existing System Chlorination: For refurbishment projects, routine maintenance, or following repairs to ensure ongoing water safety. This includes chlorination for water main repairs and replacements.
- Water Tank Chlorination: Critical for maintaining hygiene in stored water systems. Our water tank chlorination is essential for UK water safety.
- Chlorination and Legionella Control: While distinct, chlorination can be a component in managing Legionella risks in certain situations.
- Specialised Applications: We also offer chlorination for decommissioned pipelines and can advise on internal pipework chlorination cost.
we provide essential related services such as dechlorination of pipelines to safely remove residual chlorine before discharge, and comprehensive water sampling after chlorination with UKAS accredited laboratory testing to verify disinfection efficacy. Should your system require it, we also undertake internal pipe swabbing services to remove debris prior to disinfection.
The PTS Chlorination Process: A Step-by-Step Approach
To ensure a successful and compliant disinfection, Pipe Testing Services follows a meticulous chlorination process. We have moved away from restrictive accordions to provide you with a clear overview of our systematic approach:
1. System Preparation and Assessment
Before commencing any chlorination, our technicians thoroughly assess the water system. This involves:
- Evaluating the water source and system volume.
- Determining the required chlorine dosage and contact time.
- Ensuring the system is clean, flushed of debris, and ready for the disinfection process.
Any necessary internal pipe swabbing would be completed at this stage.


2. Controlled Chlorine Application
Our state-of-the-art mobile chlorination units allow us to bring our services directly to your site. We carefully introduce a precisely measured chlorine solution into the water system. This controlled application ensures the correct concentration is achieved throughout the entire system for effective disinfection.


3. Sufficient Contact Time
Once the chlorine is introduced, it requires a specific contact time (or standing time) to effectively neutralize microorganisms. This duration is calculated based on the chlorine concentration, water temperature, and system characteristics, adhering to established industry guidelines.
4. Dechlorination (If Required)
Following successful disinfection and contact time, any residual chlorine may need to be neutralized before the water is discharged into the environment or the system is put into service. Our dechlorination of pipelines service ensures this is done safely and responsibly.
5. Post-Chlorination Flushing and Testing
The system is then thoroughly flushed to remove the chlorinated water. Subsequently, water sampling after chlorination is conducted. These samples are sent to a UKAS accredited laboratory to verify that the disinfection process was successful and the water quality meets all necessary standards.
Throughout each stage, our team adheres strictly to chlorination safety protocols & PPE for water system disinfection, ensuring the safety of our personnel, your site, and the environment.

Frequently Asked Questions (FAQs)
about Chlorination Services
Chlorination should be performed regularly for stored water systems, after any new installation, modification, or major repair, or if contamination is suspected. Pipe Testing Services can assess your specific system and advise on a tailored chlorination and maintenance schedule.
Chlorine in high concentrations can be harmful. That’s why professional dechlorination is a critical step after system disinfection, neutralizing the chlorine before discharge to protect the environment. PTS adheres to all environmental regulations.
The duration depends on the size and complexity of the water system, the required contact time, and testing protocols. We can provide an estimated timeframe after an initial assessment.
Yes, Pipe Testing Services offers nationwide chlorination services across the UK from our base in Lichfield, Staffs.
Chlorination services adhere to industry standards and regulations to ensure that water treatment processes are conducted accurately and effectively. This includes complying with guidelines set by health agencies and environmental authorities.
Key benefits include its effectiveness against most waterborne pathogens, cost-efficiency, rapid large-scale treatment capabilities, and its ability to provide a protective chlorine residual in the water distribution system. Its long-standing use worldwide attests to its versatility and reliability.
Chlorine damages the cell membrane of microorganisms. Once inside, it disrupts essential life processes like respiration and DNA activity, effectively killing the cell. This makes it a tried-and-tested technique for over a century.
While beneficial for disinfection, direct exposure to high concentrations of chlorine (e.g., gas or concentrated solutions) can be hazardous. This is why professional services like ours use stringent safety protocols, appropriate PPE, and controlled dosing. Properly chlorinated drinking water, meeting regulatory standards for residual levels, is considered safe for consumption.
The required chlorine dosage depends on several factors, including the “chlorine demand” of the water (the amount of chlorine consumed by impurities before a residual is achieved), water temperature, pH, contact time, and the types of microorganisms targeted. PTS conducts careful assessments to determine the optimal dosage for each specific situation.
After initial disinfection, chlorine levels are managed to maintain a safe “chlorine residual.” This residual continues to protect the water as it travels through the system but must be within regulatory limits to be safe for consumption. Regular testing and monitoring, along with controlled dosing and dechlorination where necessary, ensure these levels are maintained.
In municipal or large-scale water treatment, chlorination can occur at various stages:
Pre-Chlorination: Adding chlorine to raw water entering a treatment plant can help control algae, reduce odours, and prevent biological growth in early treatment stages.
Pre-Filter Chlorination: Applied before filtration stages to aid in the removal of certain impurities and prevent filter biofouling.
Final Stage Chlorination (Post-Treatment): This is the primary disinfection step to kill remaining pathogens and establish the necessary chlorine residual before water enters the distribution system.
Pipe Testing Services primarily focuses on chlorination for new and existing pipeline systems, tanks, and site-specific water networks, which typica
Yes, chlorination is vital for new water pipe installations to ensure they are disinfected before being brought into service. It is also crucial for existing systems after repairs, refurbishments, or if contamination is suspected, to restore and maintain water safety.
