Pipe Chlorination for Watermain Connection

Fitz Scientific carries out water main pipe chlorinations and disinfection on behalf of Local Authorities, Utility Companies, Consulting Engineers & Building Contractors. This is completed to meet the requirements of the Irish Water Code of Practice for Water Infrastructure Connections and Developer Services.

Following the installation of a new water main or where a water supply piping system is broken or damaged and is repaired, a pipe chlorination is required. Using a standard operating procedure acceptable to Irish Water, Fitz Scientific can disinfect and test the piping system.

Our trained technicians will come on site and conduct the chlorine dosing of the water main system. The chlorine remains in the pipe for 24 hours after which it is dechlorinated and flushed with a clean supply of water. The water in the pipe is then sampled and tested during and after the chlorination.

Accredited Water Testing

The required microbiological testing is accredited by INAB to ISO 17025 standard and takes place at our laboratory in Drogheda. We issue a validated certificate of analysis and report on the chlorination procedure which may be submitted to the local authority. Tests include:

  • Escherichia coli (E. Coli)
  • Coliforms
  • Clostridium Perfringens 
  • Enterococci
  • Total Residual Chlorine
  • Free Residual Chlorine

Subject to satisfactory results the piping system is then deemed to be suitable for the supply of drinking water. The piping system can then be commissioned for use.

Developer Self Chlorination

Where the chlorination procedure is completed by the developer we can offer a microbiological sampling only service. Our technician can visit the site once the watermain has been flushed and refilled to take a bacteriological sample for analysis.

For further details on our pipe chlorination services, please contact our sales team or our Field Service technicians who will be happy to assist. Contact 041 9845440 or email info@fitzsci.ie
