Water Chlorination Services
Safeguarding water quality and public health with water system chlorination and certification (BS8558) best practice and processes.
Ensuring Safe, High Quality Water Supply
At Water Direct, we understand that water quality is paramount to safeguarding public health. Before any private supply pipes can be connected to the water main, they must undergo thorough chlorination and testing to meet strict regulatory standards. Our expert water chlorination services ensure that all new and refurbished pipework is properly disinfected, guaranteeing a safe and compliant drinking water supply.
With our industry expertise and commitment to quality, we help you meet essential water hygiene regulations efficiently and reliably.

Our Certified Chlorination Process
Our expert technicians begin with a complete flushing of the system using clean drinking water. This clears debris and creates a clean environment for effective mains chlorination.
-
Initial Disinfection
A chlorinated solution (minimum 50mg/l) is introduced and left in the system for at least one hour. This helps kill bacteria and pathogens present in the system. -
Neutralisation and Flushing
The solution is then safely neutralised and flushed out. The system is re-filled with clean water and allowed to sit for another contact period of one hour. -
Water Sampling and Testing
Final water is sampled and sent to UKAS-accredited laboratories for microbiological and chemical analysis. -
Issuing of Chlorination Certificate
Within 7 days, we provide a complete chlorination certificate and analytical report. This documentation ensures the system is compliant and safe for connection to the mains supply.

Following receipt of the analysis from the laboratories, Water Direct provides a certificate of chlorination, along with a full analytical report for each sample. These results and certificates are usually provided within 7 days of the work taking place providing assurance that the system is safe for use in the supply of wholesome drinking water. This evidence can be provided to the incumbent water utility to enable a connection.
When is a chlorination needed?
- Prior to connection of new pipe work to the mains supply – otherwise water utilities have the right to refuse connection.
- If there is any suspected contamination to the supply.
- If the pipe work or welfare units have not been used for an extended period of time.
- Any new build properties.
- Installation or maintenance of sprinkler systems.
