Risk Assessment
6.1 ECS will, through the Deputy Responsible Person, arrange for suitable and sufficient risk assessments of water hygiene to be undertaken on all university buildings, unless this responsibility has been passed to a 3rd party such as a tenant.
6.2 In addition ECS will schedule, design, order and monitor all controls necessary to reasonably and practicably manage Legionella bacteria within OBU University and have appointed a competent contractor to carry out this function.
6.3 Relevant information will be held on an appropriate system accessible by relevant stakeholders including appropriate staff within ECS and the H&S department.
6.4 Risk assessments will be reviewed at least every five years or sooner if there is a significant change to the water systems or considered appropriate by the Responsible Person, Deputy Responsible Person or Contracts and Compliance Manager (Mechanical). Appendix 1 provides an overview of the University water systems and responsibility for the management of these.
Management of Hot and Cold Water Systems
6.5 All hot and cold water systems can potentially lead to Legionella proliferation if water is allowed to stagnate at ambient temperatures (between 20 – 450 C. The risk of the disease occurs when contaminated water is in aerosol form. This can be a particular concern associated with infrequently used outlets.
6.6 Infrequently used outlets will be flushed on a weekly basis or more frequently should the monitoring or risk assessment indicate the need. ECS will coordinate the flushing programme.
6.7 Those undertaking flushing must maintain accurate records of the flushing being undertaken.
6.8 Microbiological Monitoring: Microbiological monitoring of domestic hot and cold water supplied from the mains is not usually required, unless the risk assessment or monitoring indicates there is a need. The risk assessment should specifically consider systems supplied from sources other than the mains, such as private water supplies and sampling and analysis may be appropriate.
6.9 Communication Pathway: a separate document detailing an appropriate communication pathway is held with the Engineering Department and shared with relevant stakeholders including external contractors. A diagram, summarising roles and responsibilities for communication purposes can be found in Appendix 2.
Management of Void Periods within Residencies
6.10 Students have access to the residencies throughout the full period of their licences. However, the University recognises there are periods when students are more likely to vacate the residencies for a period of time. Typically these are the Christmas, Easter and Summer periods. During these times ECS will arrange for additional weekly flushing of the water systems.
6.11 Where the students have notified Residential Services that they will have vacated their rooms at any time, this accommodation will be added to the ‘Void Rooms’ list, shared with ECS for additional flushing of the water outlets.
