Water hygiene and Legionella management policy (Housing Property Portfolios)

2. Introduction

This policy sets out the aims and objectives of Waverley Borough Council (WBC) to control water quality within their housing properties. It is to be read in conjunction with the Water Hygiene Management Plan and Procedures document and the individual Written Schemes produced for each property following the completion of a Risk Assessment. The Water Hygiene Management Plan and Procedures document and the Written Schemes provide further information and site-specific detail of how this policy should be implemented. 

The aim of this policy is to introduce a structured responsibility and reporting schedule for the Management and Control of Legionnaires’ disease, including Legionellosis and “Safe” water, in compliance with current guidelines, legislation and Water Supply Regulations. 

This policy details WBC’s duties regarding the safety of its employees, tenants, occupants, leaseholders, visitors, neighbours, the general public and any others likely to be affected. This Policy and the associated Water Hygiene Management Plan and Procedures, documents require all parties to comply with. 

WBC's property portfolio is varied and includes properties of various sizes and risks. This Policy covers all the properties identified below: 

Social housing properties 

  • houses 
  • flats and flat blocks 
  • maisonettes 
  • bungalows 
  • bedsits 
  • housing units 
  • Senior Living Schemes  
  • community rooms.

3. About Legionella 

Legionella bacteria are common and can be found naturally in environmental water sources such as rivers, ponds, lakes and reservoirs, usually in low numbers. They can colonise manufactured water systems and can be found in cooling tower systems, hot and cold water systems and other plant equipment which is used for stored water. 

To reduce the possibility of creating conditions in which the risk from exposure to Legionella bacteria is increased, it is important to control the risk by introducing measures which: 

  • do not allow proliferation (multiplication) of the organisms in the water system
  • reduce, so far as is reasonably practicable, exposure to water droplets and aerosols. 

Legionella bacteria can survive within a wide variety of environmental conditions and water temperatures in the range 20°C to 45°C, seem to favour growth. The organisms do not multiply below 20°C but become dormant and will not survive above 60°C for longer than several minutes. They may, however, multiply only when water temperatures reach a suitable level.

Legionella bacteria also require a supply of nutrients to multiply. Sources can include, for example, commonly encountered organisms within the water system itself such as algae, moulds, yeasts, amoebae and other bacteria. The presence of sediment, sludge, scale and other material within the system, together with biofilms, is also thought to play an important role in harbouring and providing favourable conditions in which the Legionella bacteria may grow. 

A biofilm is a thin layer of micro-organisms which may form slime on the surfaces in contact with water. Such biofilms, sludge and scale can protect Legionella bacteria from temperatures and concentrations of biocide that would otherwise kill or inhibit these organisms, if they were freely suspended in the water. 

WBC recognises the risk from Legionella bacteria within the buildings controlled by them, and the requirement for employees and contractors to comply with this policy and the associated procedures in conjunction with all current legislation.

4. Policy statement for Legionella control 

Water quality can represent a significant risk to health as highlighted by regular outbreaks of Legionnaires’ disease. The responsibility of WBC to achieve control within accepted parameters is formally recognised by this policy.  

Legionnaires’ disease can prove fatal as confirmed by several preventable cases. WBC will seek to address preventable cases of Legionnaires’ disease across their building portfolio for the protection of staff, contractors, and visitors. The associated liability of such an outbreak, with any media attention exposure, attached to even a suspected outbreak, necessitates the need for clear, concise guidelines to be published. These guidelines must give recommendations to be taken to prevent Legionella bacterium multiplying within the buildings owned or managed by WBC. 

WBC accepts their responsibilities to take every reasonable precaution necessary to protect the welfare of people occupying and visiting their properties, as well as those passing by their buildings. To ensure that the highest standards reasonably practicable are maintained, guidance relating to the prevention of Legionella, issued by authorities such as the Health & Safety Executive and the British Standards Institution, relating to the prevention of Legionella will be adopted where relevant.   

The foundation to WBC’s approach to water quality control is: 

  • identify and assess sources of risk
  • prepare a scheme for preventing, removing, reducing or controlling the risk, including actions to be taken in the event of loss of control
  • implement, manage and monitor all precautions possible
  • keep records of the provisions implemented
  • appoint appropriate persons to be managerially responsible for the implementation of this Policy.

It is WBC’s policy that Water Research Advisory Scheme (WRAS), approved materials or their equivalents such as KIWA Watertec or NSF International are used on their water systems. 

Risk assessments and record keeping are a statutory requirement for the control of Legionella. WBC will ensure this is implemented as identified within the Water Hygiene Management Plan and Procedures document. 

All employees have a role in protecting health and safety for all and water quality is part of this. Such basic information will be provided to all employees, and specific training and instruction will be given to all those directly involved with water safety management, to ensure competency levels are suitably maintained. 

This Policy will be reviewed every two years, or whenever there is a reason to believe that this policy is no longer fit for purpose.

5. Responsibilities

WBC as employers have a general duty under The Health and Safety at Work Act 1974 to ensure so far as is reasonably practicable, the health, safety and welfare of all their employees. Employees have a duty to take reasonable care for their own health and safety and of that of others who may be affected by their acts or omissions at work. It also requires the employee’s co-operation with their employer, to enable the employer to comply with their statutory duties for health and safety. 

Management has the overall responsibility for the implementation of this Policy to ensure that safe, reliable water supply, storage and distribution systems are operated within WBC housing properties. In addition, management has a statutory duty to ensure that compliance with this Policy is continual and not assumed. WBC must be able to demonstrate it has identified all the relevant factors, has instituted corrective or preventive action, and is monitoring the implemented plans. 

It is the responsibility of any person employed by WBC in whatsoever capacity to comply with the requirements of this Policy.
