Legionella and Pseudomonas

Legionnaires Disease and Pontiac Fever are caused by bacteria from the species Legionella. Many countries have legislation in place to control the problems associated with these bacteria in the engineered environment and therefore a site has to comply with these regulations.

Collaton Consultancy Limited’s strength is helping sites comply with these regulations and put in place robust systems for compliance. The model below describes our approach to this problem as we help sites put all the various parts of this process together and then audit on a regular basis to ensure compliance.

Whether you are an end user or a water hygiene company looking for independent help and support Collaton Consultancy can help you comply with current legislation and guidance. Putting together the road map to success using the skills and knowledge is part of the solution to enable compliance to the relevant regulations.

Our training will then embed this knowledge into your team ensuring each and every part understands the importance of their role and how to help overcome these bacterial problems on site.

Whether you are an end user or a water hygiene company Collaton Consultancy Limited have staff that can help you with all aspects of Legionella and Pseudomonas control on site. Dedicated, secure, SharePoint micro-sites can be created for customers to help collect information and share with all site staff enabling one location for all Legionella and/or Pseudomonas information. Workflow processes can then be created to ease the flow of information between staff and Collaton Consultancy Limited
