Proven water treatment solutions for facilities management

Systems that heat, cool, store and distribute water are as important as power and IT infrastructure for almost every type of building. These water systems require careful and specialist management, maintenance and optimisation to ensure they are effective, efficient and safe.

Water that is correctly treated will help to drive down energy costs, ensure the health and safety of your building’s occupants and help you to achieve compliance with environmental regulations and standards. Calling upon decades of experience in delivering and managing water treatment systems for a broad range of premises, our qualified water chemists, microbiologists and engineers will help you to safeguard your:


•   Steam and hot water boilers

•   Condensate lines

•   Cooling towers

•   Domestic systems

•   Waste water treatment plants

•   Reverse osmosis systems

•   Disinfectant systems

Safeguard your facilities against risk

Water systems are inherently exposed to a number of risks throughout their operation. These risks will have a direct impact on your building’s energy consumption, water usage and health and safety compliance, unless they are skilfully assessed and managed. Every building is different, however most face common issues with their water systems, which include:


The build-up of scale within heat exchange equipment for example, can cause a multitude of problems. It is estimated that even 1mm of scale on the surface of your heat transfer system could increase energy bills by up to 25%. This extra energy and the extra strain it adds means that the equipment ages at a much faster rate, requiring more repairs and replacement sooner than expected. To avoid the problems caused by scale, you need to know what scale is, the problems caused by scale and ways in which it can be treated.


Corrosion within water systems causes two major system problems, the first of which is damage to the metals within the system, which leads to expensive repairs and ultimately system failure. The other problem is the reduction of the system’s effectiveness, which leads to an increase in the energy and water required for the system to complete the job it’s there to do. To control corrosion, you need to first understand what creates corrosion, the problems it causes, and methods of combatting it.

Legionella and microbiological contaminants

Failures in the design, operation, maintenance or monitoring of man-made water systems can allow bacteria including Pseudomonas, E. coli and Coliform to thrive, posing a risk to the health of your building’s occupants. Legally, your building manager has a requirement to control the risk from Legionella. To achieve compliance, the basis of good practice in water supply system design is to assess and then remove the conditions that promote bacterial growth.

Whatever your system and water requirements, our expert risk assessments, testing methodologies, treatment chemicals, system cleans and dosing systems will help you to manage risks efficiently, effectively and safely.

Ensure compliance and meet industry standards

The UK has strong regulatory frameworks governing the design and operation of water supply systems. The best way to ensure compliance is through improving the knowledge and competence of operators and managers involved with the maintenance of all water systems, including cooling towers and evaporative condensers.

What our customers say:

SUEZ provided speciality chemical treatment for our closed water systems but this has been increased to cover all our air and water hygiene requirements. They have continued to provide reliable, consistent service and recommendations to improve critical systems on site to meet BS 8552. SUEZ have provided high quality legionella risk assessments carried out by independent risk assessors that have helped to benchmark the domestic water systems on site to comply with the Legionella Approved Code of Practice. The company [SUEZ] has consistently offered a high level of service which I fully endorse.
