Control Schemes & Audits

ChemTech Consultancy can provide site specific logbooks to record all monitoring results and hold relevant records.  This may be in either paper format, where a site logbook is physically retained by the client to record all monitoring records or can be in electronic web-based format.  Resulting from the risk assessment, control schemes are written for implementation by the client. Often clients will contract us to carry these out, all or part of these, on their behalf for their domestic water services.  Clients are then able to choose from a menu of options often requesting ChemTech Consultancy to carry out some or all of these duties on their behalf.

Temperature Monitoring

L8 requires that sentinel points, cold water storage tanks, calorifiers, showers and random outlets are all monitored at specific intervals with many being on a monthly basis.  Our team of field based service technicians carry these out, recording results in the site logbook or uploading via our PDAs onto the client’s electronic system to allow for real time access to records.    Where the records are in paper format, ChemTech Consultancy would leave Customer Service Reports detailing works and any corrective actions required. If in electronic format ChemTech Consultancy would use a PDA system to upload the client’s report to the electronic management system. All information provided will allow the client to manage all ACoP L8 monitoring requirements.

Inspection Services

Part of the ACoP L8 monitoring requirement involves the inspection of Cold Water Storage Tanks, Water Heaters and Calorifiers annually.   ChemTech Consultancy carries out these services using our highly trained technicians whose experience ensures that appropriate recommendations regarding any requirements for Cleaning and Disinfection or remedial works are met.  These inspection reports are accompanied by photographic evidence to allow the client to better understand the reasoning behind the recommendations.

Showerhead Cleaning and Disinfection Services

Part of the control scheme for clients with showers is often quarterly clean and disinfection of their showerheads and spray taps.  An alternative for this is our low cost showerhead exchange programme where a new unit is supplied each quarterly and the old one recycled.

TMV Servicing

Risk Assessments often recommend this is carried out in accordance with manufacturers instructions.  This is something our Technicians are trained to do and can be incorporated into a routine service plan.

The Approved Code of Practice L8:2013 “Legionnaires Disease – The control of legionella in water systems”, paragraphs 25, 32, 46,47,52,56, 65-69 and 70-74 confirms the need to periodically review, update and audit management procedures; communication systems; training requirements; risk assessment validity; written control schemes and record systems. Lines of communications should be clear, unambiguous and audited regularly to ensure that they are effective.
