Our Process: Thorough, Professional, Compliant

We follow a meticulous process tailored to each system’s needs:

  • Site Survey & Risk Assessment

    We begin with a detailed inspection and risk assessment of your cold water storage vessel.

  • Drain & Isolate

    The vessel is safely drained and isolated from the water system.

  • Manual & Mechanical Cleaning

    We remove scale, biofilm, and debris using safe mechanical tools and manual scrubbing.

  • Rinse & Refill

    After chlorination, the system is flushed thoroughly with fresh water to remove residual chemicals.

  • Water Sampling & Certification

    We take samples for lab analysis (if required) and provide a disinfection certificate upon completion.

Why Cleaning and Chlorination Are Important

Without regular maintenance, water storage systems can become breeding grounds for:

  • Bacteria and viruses, including Legionella and E. coli

  • Sediment and sludge, which affect water quality and pressure

  • Corrosion, which reduces tank lifespan and damages plumbing

Regular cleaning and chlorination help prevent these issues and ensure water quality meets ACoP L8, HSG274, and BS EN 806 standards.
