A key aspect of The Approved Code of Practice (ACOP) L8 is to maintain the cleanliness of all water systems. A regular, comprehensive, physical and chemical clean of these systems will limit the potential for high bacteria counts. When followed by regular monitoring the employer ensures that their staff, customers and the public are protected as well as complying with codes of practice.
By appointing AES on a contracted basis, management are relieved from such checks and are offered peace of mind that they are meeting the latest required guidelines of maintaining safe water. Records for inspection are guaranteed to be kept up to date and in the event of any ‘out of range’ results, AES are able to respond immediately to offer the appropriate remedial services. |

A monitor and inspection contract will provide a combination or all of the following services to an agreed programme, with careful consideration to the building’s use and occupancy.
Physical examination
- Visual inspections by trained operatives of circulation within storage vessel
- Visual inspections of any build up of calcium carbonate scale, sediment, biofilms and signs of corrosion, potential growth accelerators for bacteria (particularly Legionella pneumophila), which can often be overlooked by untrained personnel
Water temperature measurements
- To assess the physical temperature of the water services to establish safe thermal conditions exist
- Digital read out meters, immersion and contact temperature probes
- All testing is undertaken using equipment which has been pre-calibrated, in accordance with UKAS accredited test methods
- The optimum growth temperature for Legionella pneumophila is between 35°C and 46°C and it is a recognised fact that this bacteria can readily multiply in water systems that are within a temperature range of between 20°C and 50°C
Dip slide measurements
- To assess outlets for bacteria / yeast and mould counts
- Inoculation process adheres to supplier guidelines
- Incubation at 30°C for 48 hours according to guidelines (e.g. HSE)
- Comparison charts provide colony forming units per millilitre for interpretation of results
Service
- Regular reminder of programme activities by a dedicated account manager
- Production of results for client record log book
- Photographic record
- Immediate response to any results outside pre-determined tolerances
- Corrective recommendations by an experienced management team
- Ability to offer all corrective works in-house (see clean and disinfect and tank refurbishment)
