Water Chlorination & Water Tank Cleaning Services

Cleaning and Chlorination of Water Storage Vessels

Acorn offers a range of cleaning services to HSE ACoP L8 standard as a part of our water management programme.

Acorn can undertake the cleaning and chlorination of all forms of water storage tanks from a small plastic tanks to large sectional vessels. Our engineers are also “confined spaces” trained for those hard to reach underground tanks. Acorn engineers use the following chemicals in completion of these chlorination works:

  • Sodium Hypochlorite
  • Silver Hydrogen Peroxide

All chemicals used by Acorn Environment Services staff are COSHH risk assessed by our Health and Safety department and stored in a locked facility at our property. A site survey before works are carried out means only the required amount of chemical will be brought onto your site. This reduces the potential for any spillage during the works being completed.

Calorifier Cleaning/Disinfection

HSG 274 (part 2) recommends annual internal inspection of domestic hot water calorifiers (Table 2.1, page 31)

Calorifier cleaning can be achieved by removing the inspection hatch or using a boroscope and clean by draining the vessel. The frequency of inspection and cleaning should be subject to the findings and increased or decreased based on conditions recorded.

Showerhead Cleaning, Descaling & Disinfection

HSG 274 (part 2) recommends that showerheads and spray outlets should be treated quarterly or as indicated by the rate of fouling or other risk factors e.g areas with high risk patients.

Acorn engineers will:

  • Dismantle
  • Clean
  • Descale
  • Remove parts, heads and hoses where fitted

Chlorination certificates along with photographic evidence of the completed works will be sent to the client on the above services.
