Legionella Monitoring

Dutyholders should frequently perform a thorough risk assessment of hot and cold water systems and ensure that acceptable actions are put in place to manage risks.

Managed Water Services will assess the usage of all systems, the types and number of people who will be exposed to the systems and recommend a control scheme for ongoing compliance. Accurate temperature sensors and trained engineers will then ensure you meet your legal obligations.

Legionella Risk Assessment

The production of a Legionella Risk Assessment is the first step to ensuring that water treatment is carried out effectively to minimise risk. Managed Water Services believe that this is not only the first but also the most vital part of any water treatment and management system. We can also deliver the remedial actions (if any) through our qualified technicians.

All audits of existing Legionella control systems and procedures undertaken by Managed Water Services are designed to be exhaustive and give clients peace of mind that their responsibilities are met and full compliance with legislation is achieved.

Legionella Training

Inadequate management, lack of training and poor communication are all contributory factors in outbreaks of legionnaires’ disease and our training packages are designed to overcome these issues. 

COSHH: regulations 8 and 12; Management Regulations: regulations 5, 7, 10 and 13; and HSW Act: sections 2, 3 and 4 require employers to have arrangements in place for the management of health and safety, to have access to competent health and safety advice and to provide employees with suitable and sufficient information, instruction, and training. 

The verb “train” appears 26 times in the ACOP, and for good reason. Good training for your staff is a key factor in making sure your water system operates safely. 

Water Treatment

Your requirement is unique and we can design a treatment plan to meet your needs. We can provide you with the correct water treatment chemicals and a dedicated, trained service engineer which means that your system will run safely and efficiently.

By minimising fouling potential, you may be able to justify extending the period between more intrusive practices.

Whatever system you have, we will implement a robust treatment program so you can keep on doing what you do best and not worry about water.

Cleaning & Disinfection

It is vital to ensure that any plant that stores, supplies and/or carries water is clean. As water is passed through the systems, sediments and debris which provide nutrients that helps Legionella thrive, can accumulate. Managed Water Services qualified technicians can undertake a range of system disinfections under any planned preventative maintenance programmes in accordance with ACOP L8.

Water Softener Servicing & Installation

Managed Water Services can design, supply, install and service softeners of all sizes to meet any pre-treatment demand.

Hard water is known to foul systems, harbour bacteria and have severe cost implications where there is heat transfer i.e. hot water calorifiers. A water softener can improve the efficiency of your systems and increase the longevity of your connected assets.

Water softeners contain many moving parts that will wear with time. It is important to replace certain parts of the water softener on a regular basis to ensure that slippage does not occur, and the plant continues to protect your assets.

Water Sampling

As part of Managed Water Services’ holistic approach to water management, we can provide a complete water analysis service to enable the correct pro-active or reactive actions to be taken.

Water supplies are tested to determine the levels of bacteria (including Legionella) present.

Closed water systems, such as chilled water circuits linked to air conditioning, are also tested as some bacteria can cause corrosion of the pipework/valves.

TMV Servicing & Testing

At Managed Water Services we can specify, supply, install, service and replace all Thermostatic Mixing Valves (TMVs). A TMV secures safe temperatures by blending the hot and the cold water. It should be of high priority to service this valve as poorly fitted or dirty TMV’s can increase the Legionella risk. TMV’s are typically fitted in places where vulnerable people could be exposed to a scalding risk.

RPZ Installation & Testing

In line with WRAS water regulations, it is required by law that Reduced Pressure Zone (RPZ) valves are to be tested and certificated annually.

Managed Water Services have WRAS accredited engineers, carrying out all testing, maintenance, installations and commissioning, conforming to all legal requirements with nationwide coverage.

Cooling Tower Endoscope Inspection

An endoscope inspection of cooling tower pack is a method of assessment to determine fouling and deposition in these intricate pieces of the plant. The pack can become fouled with a wider range of deposits than that found in the pond or other system sumps and is a good indicator of the overall system cleanliness. It may be acceptable to extend the period between cleaning operations provided you can demonstrate that system cleanliness is maintained. Contact Managed Water Services for more information or a bespoke proposal for endoscopic inspection of your cooling tower pack.

Chlorine Dioxide Generators

Chlorine Dioxide is an excellent biocide that is effective in a wide range of water systems and is used widely as disinfection agent. It will not only kill free-floating bacteria, it will also penetrate the bio-film, help to break it down and kill pathogens that are buried within. At Managed Water Services we design, supply, install and service Chlorine Dioxide Generators.

The MWS Water Master is an automatic dosing system designed to dose potable and domestic water systems that can be linked to a building management or on-site alert system. The unit is pre-packaged and can be retro-fitted to most water systems.

Chemical Dosing Equipment

Automated chemical dosing systems are a key element of compliance. They also deliver cost-savings, minimise time spent on maintenance and take away the headache of having to make constant adjustments. The design, supply, installation and servicing of these systems is one of MWS’ core capabilities. A member of our team will liaise with you throughout each stage and give you peace of mind that the system will deliver on your requirements. Utilise our experience and knowledge for these important projects to ensure optimum system performance for the future.
