Cleaning
And
Disinfection

Key components of your water system, such as cold water storage tanks, calorifiers, water heaters, and buffer vessels — should be cleaned and disinfected whenever there is a build-up of debris.

Debris like biofilm, scale, and sediment not only reduces system efficiency but also provides ideal conditions for harmful waterborne bacteria to grow. Regular cleaning helps prevent the spread of pathogens and keeps your water system safe and compliant.

We understand how important it is to keep your site running smoothly. Our equipment and methods are specifically designed to reduce downtime during the cleaning and disinfection process, helping you maintain normal operations with minimal disruption.

Cleaning And Disinfection

When water systems fall into poor condition, the risk of harmful bacteria, like Legionella Pneumophila, increases. These bacteria occur naturally in the environment but can quickly multiply in man-made water systems, especially in large, complex buildings such as hospitals, office blocks, and care homes.

In these environments, contamination can spread rapidly if systems are not properly maintained.

Biocide Dosing for Water Safety

When temperature control alone isn't enough to manage Legionella and other waterborne pathogens, biocidal treatment may be required.

Choosing the right system is complex and depends on factors like system design, age, size, and water chemistry — there’s no one-size-fits-all solution.

Continual biocide dosing must be carefully planned and monitored. If not implemented correctly, it can impact water quality and even breach water regulations. It’s essential that the treatment controls risk without introducing new hazards.

Aqua Protec’s consultants assess your system and recommend the most suitable dosing method to maintain water safety and compliance.

Approved Plumbing Services

Aqua Protec ensures all plumbing work is delivered, installed, and commissioned in line with manufacturer guidelines to protect your warranty.

We’re certified members of the Approved Contractors’ Scheme by Severn Trent Water, WaterMark, and WaterSafe. This means we can issue a certificate of compliance for any plumbing work we carry out, confirming it meets the Water Supply (Water Fittings) Regulations 1999.

Existing Pipework Disinfection

If there are concerns about the safety or quality of your hot and cold water — such as unusual taste, smell, or appearance — a local or full system disinfection may be required. This is especially important if water testing shows unacceptable levels of bacteria like Legionella or Pseudomonas Aeruginosa, or if other control measures have failed.

Aqua Protec uses advanced disinfection techniques tailored to your system. Before any work begins, our consultants assess the setup to ensure the right chemical strength, contact time, and method are used in line with regulations.

New Pipework Installations

New pipework must be disinfected before use to ensure it’s free from bacteria that could grow once the system is live. Aqua Protec supports new build and refurbishment projects by offering:

Pre-commission disinfection
Analytical sampling
TMV validation

All work is completed to the standards set by BS8558:2015 and PD855468:2015, supporting plumbing and mechanical contractors throughout the process.

Mothballed Water Systems

When buildings such as universities or schools are unused for extended periods (over 30 days), water stagnation can lead to bacterial growth. While draining complex systems is often impractical, leaving them full without proper maintenance is risky.

Aqua Protec provides planned support for temporarily closed systems, including:
