Cold Water Storage Tank Chlorination

As part of your on-going water hygiene programme, HSE ACoP L8 / HSG274 advises that the following be carried out:

Annually – Inspect cold water storage tanks and carry out remedial work where necessary

Annually (Summer) or as indicated by the temperature profiling

Check the tank water temperature remote from the ball valve and the incoming mains temperature. Record the maximum temperatures of the stored and supply water recorded by fixed minimum/ maximum thermometers where fitted.

Waterman Environmental Services are a specialist water hygiene company and can provide the following chlorination services to help you maintain water quality. All our highly qualified operatives hold the Water Hygiene Card enabling them to work on potable water and we use specialist equipment to ensure both consistent dosing of chlorine and maintain water supply integrity, which is a must when carrying out a chlorination on a potable mains supply.

  • New mains chlorination
  • Water tank cleaning and chlorination
  • Entire disinfection of water down services within buildings
  • Chlorination of process systems such as cooling towers
  • A chlorination certificate is issued for all work carried out

WES will conduct a comprehensive Risk Assessment Method Statement (RAMS) survey prior to any works being carried out on site producing a schedule of works package for specialised chlorination works. We will always work with you to ensure the minimalist levels of disruption, ensuring all work carried out exceeds your expectations.

Commercial water storage tank cleaning can present additional problems due to access restrictions and working environment. WES are able to provide safe solutions that allow us to properly clean these tanks; all technicians are certified for confined space working.

Following the chlorination and cleaning of the water tank we provide a detailed report including pre and post work colour photographs illustrating the condition of the tank as well as a chlorination certificate and can provide water testing services through our in-house UKAS accredited laboratory to give confidence in the cleanliness of the water system.

Our clean and chlorination experts are vastly experienced in all areas of water treatment and will advise you of the best and most cost effective methods to keep your water systems compliant.
