Water Treatment and Legionella Services in Dundee

Express Heating & Plumbing provides professional water treatment, water hygiene, and Legionella control services throughout Dundee and the surrounding areas. We support commercial, industrial, residential, healthcare, hospitality, and public-sector properties in maintaining clean, safe, and efficient water systems.

Poorly maintained water systems can allow scale, corrosion, sediment, and harmful bacteria to develop. This can reduce system efficiency, damage equipment, affect water quality, and create avoidable health and compliance risks.

Our experienced team can inspect your water systems, identify potential problems, and recommend practical treatment and maintenance measures suited to your property.

Water Treatment and Hygiene Services

We provide a range of water treatment services designed to protect building users, plumbing systems, heating equipment, and stored water supplies.

Our services include:

• Legionella Risk Assessments: Inspection of hot and cold-water systems to identify conditions that may encourage Legionella growth.
• Legionella Water Testing: Sampling and testing of water systems where monitoring or further investigation is required.
• Temperature Monitoring: Checks at outlets, storage vessels, calorifiers, and circulation systems to confirm suitable operating temperatures.
• Water System Cleaning and Disinfection: Cleaning, flushing, and disinfection of tanks, cylinders, pipework, outlets, and associated equipment.
• Cold Water Storage Tank Inspections: Assessment of tanks for contamination, sediment, corrosion, poor insulation, and unsuitable operating conditions.
• Water Sampling: Sampling for microbiological and water-quality analysis where appropriate.
• Scale and Corrosion Control: Treatment solutions designed to reduce limescale, corrosion, and internal damage within water systems.
• Closed-System Water Treatment: Chemical treatment and monitoring for commercial heating and chilled-water systems.
• System Flushing: Removal of stagnant water, debris, sediment, and contamination from underused or newly installed pipework.
• Remedial Plumbing Work: Alterations to remove dead legs, improve circulation, repair tanks, replace fittings, and correct identified system risks.

Legionella Control and Prevention

Legionella bacteria can develop in water systems where water is stored or circulated at unsuitable temperatures, particularly where sections of pipework are rarely used or water is allowed to stagnate.

Properties with larger or more complex systems require careful monitoring and maintenance. This can include hotels, care homes, hospitals, schools, apartment developments, offices, leisure centres, and industrial premises.

Our team can help identify common risk factors such as:

• Stagnant or infrequently used outlets
• Incorrect hot or cold-water temperatures
• Poor circulation within the system
• Dead legs and redundant pipework
• Contaminated or poorly maintained storage tanks
• Scale, rust, sludge, and organic material
• Showers, spray taps, and other aerosol-producing outlets
• Inadequate cleaning and maintenance procedures

Where issues are identified, we will explain the findings clearly and recommend suitable corrective action.

Water System Cleaning and Disinfection

Water systems may require cleaning and disinfection following installation, refurbishment, contamination, long periods of inactivity, or an unsatisfactory test result.

Our engineers can carry out controlled cleaning and flushing procedures across relevant pipework, storage vessels, outlets, and equipment. We work carefully to minimise disruption and help return the system to safe and dependable operation.

Where required, we can also complete associated plumbing alterations and repairs as part of the remedial work.

Closed Heating and Chilled-Water Treatment

Commercial heating and cooling systems rely on correctly treated water to operate efficiently. Without suitable protection, corrosion, scale, sludge, and bacterial growth can restrict circulation and damage boilers, pumps, valves, heat exchangers, and pipework.

Our closed-system water treatment services can include:

• System water testing and condition checks
• Chemical cleaning and flushing
• Corrosion inhibitor treatment
• Biocide dosing where appropriate
• Magnetic and dirt separator installation
• Side-stream filtration
• Expansion vessel and pressure checks
• Ongoing monitoring and maintenance

Correct water treatment can improve system performance, reduce breakdowns, and extend the lifespan of valuable mechanical equipment.

Water Hygiene Support for Commercial Properties

Express Heating & Plumbing works with landlords, facilities managers, property management companies, business owners, and public-sector organisations to help maintain dependable water hygiene standards.

We can provide one-off investigations, planned maintenance, remedial plumbing work, and ongoing support tailored to the size and complexity of your building.

Whether you require Legionella testing, water-system disinfection, storage tank inspections, closed-system treatment, or corrective plumbing work, our Dundee-based team can provide a practical and reliable service.
