Water Tank Clean and Disinfection

Understanding why water tank cleaning is important is the first step to ensuring water safety. The quality of the water your property’s water system provides depends directly on the cleanliness of your tank. Maintaining a clean water tank is critical, as over time all tanks accumulate hazardous materials.

A neglected tank allows several serious issues to develop:

• Sediment & Sludge: Dirt and debris settle at the bottom, creating a thick sludge.
• Biofilms: A slimy layer forms where bacteria, like Legionella, can shelter and multiply.
• Rust & Stagnation: Stagnant water accelerates corrosion, allowing rust to flake into your supply.
• Pests & Debris: Poorly sealed tanks risk contamination from insects and other debris.

For these reasons, professional cleaning is an essential part of any water hygiene program. Both cleaning and disinfection is essential for keeping your water safe.

The single greatest danger is the growth of legionella bacteria in water, which causes the potentially fatal Legionnaires’ disease and can impact entire water heating systems, especially in poorly maintained cold water storage tanks. As a property owner, you have a legal duty to control this risk.

Legionella thrives inside a dirty tank where specific conditions are met:

• Stagnant Water: Allows bacteria to settle and multiply.
• Ideal Temperature: The water sits between 20-45°C.
• Nutrient Source: Sludge and biofilms provide a perfect food source.

Failure to manage these conditions can lead to severe penalties. Our professional tank cleaning and disinfection services ensure these risks are managed. This primary control measure is required by law and directly removes the breeding ground for bacteria.

Our professional water tank cleaning service is a complete solution designed to cleanse your water system and restore it to a safe, hygienic, and compliant state. We provide an outstanding tank cleaning service that eliminates every level of contamination.

The service tackles all threats, from physical debris to microbiological risks. Our service guarantees:

• Guaranteed Compliance: The service is performed in line with ACoP L8 and HSE guidelines.

To guarantee effective water tank cleaning and maintenance, we follow a meticulous five-step process that includes chlorination. This transparency means you know exactly what is being done to make your system safe.

Step 1: Initial Risk Assessment and Safety Checks

Before any work begins, our technicians conduct a full site-specific risk assessment, identifying any potential hazards to ensure a safe working environment.

Step 2: Draining the Water System

We safely isolate the tank and then drain the tank completely. All water and waste are disposed of responsibly and in accordance with environmental guidelines.

Step 3: Sludge and Sediment Removal

Once empty, our technicians perform a thorough cleaning. All sludge, sediment, and biofilm are manually scraped, scrubbed, and vacuumed from all internal surfaces.

Step 4: Full Tank Clean and Disinfection

With the tank physically clean, we apply our chemical disinfectant solution. We use powerful and approved cleaning agents to kill all invisible microbiological threats, including Legionella.

Step 5: Final Flush and Water Supply Recommissioning

The tank is flushed with fresh, clean water to remove all traces of chemicals, leaving clean, chlorinated water. We then recommission the system, ensuring clean and safe water is flowing correctly.

We provide tank cleaning services for everything from small domestic tanks up to large commercial water systems. Our technicians apply the same meticulous standards to every job.

• Implement Control Measures: Remove the biofilms where bacteria thrive.
• Provide Proof of Action: Create a clear audit trail with certification.

How often should my water tank be cleaned?

There is no fixed timeframe on how often water tanks must be cleaned, as the legal frequency is determined by a risk assessment. However, for tanks supplying potable water (drinking water), an annual water tank inspection and clean is the UK best practice. Regular inspections of your water tank will determine the precise schedule.

How long does a tank clean take?

A domestic tank clean typically takes 2-4 hours. Larger commercial systems can take longer depending on size, access, and the level of contamination.

What is the cost of a water tank cleaning service?

The cost varies based on the tank’s size, location, and condition. Please contact us for a free, no-obligation quote tailored to your system.

Can I clean the water tank myself?

We strongly advise against it due to significant safety risks from confined space entry and the handling of hazardous chemicals. For your safety, always use a trained professional.
