Legionella (ACOP L8) Compliance

ACOP L8 Legionella Information, Compliance, Consultancy & Advice

It is of paramount importance that all water systems have stringent Legionella control regimes in place to ensure their water systems are compliant with the Health & Safety Executive’s Approve Code of Practice (ACOP L8)

If water systems are not continuously monitored and maintained in line with ACOP L8’s technical guidance HSG274 it can leave systems at risk from the proliferation of harmful bacteria such as Legionella.

Legionnaire’s disease predominately affects people who have a suppressed immune system, smokers, and people over the age of 50. Legionnaires’ disease is form of pneumonia which can be fatal if contracted via an aerosol which is subsequently inhaled by the victim, often via showers, or misting systems.

It is a crucial part of a duty holders responsibilities to ensure that these systems are safe. If Legionella bacteria is found in a system via the sampling of outlets such as taps and shower hoses it is the duty holders responsibility to find the source of the outbreak.

Legionella bacteria in the lungs can develop into Legionnaires’ Disease

In some cases these investigations can reveal poorly maintained cold water storage tanks or cooling towers which have heavily corroded internal walls or GRP cold water storage tanks which are suffering from heavy black sporing of the water tanks internal gel coat.

All of these issues are non-compliant with ACOP L8’s guidelines and remedial action must be considered.

Legionella is a bacteria that can be naturally found in almost all water sources however the risk of proliferation is increased when Legionella bacteria is introduced to an environment which attributes to its growth.

Actions to be Considered

The approved code of practice (ACOP L8) technical guidance HSG274 provides guidance and practical solutions on how to help control or prevent the risk of exposure to Legionella bacteria from water sources such as cooling towers and cold water storage tanks.

Regular maintenance and monitoring of systems and associated outlets which could include temperature monitoring and sampling of outlets.
Minimalising the use of materials in water systems that could potentially harbour harmful bacteria, it is good practice to only use WRAS approved products when carrying out remedial actions.
Essentially it is a duty holders priority to ensure all possible actions are taken to avoid conditions which allow for the proliferation of harmful bacteria such as Legionella.
Avoid possible stagnation in cold water storage tanks as well as the build up of legionella bacteria harbouring sediment. Regular clean and disinfection’s should be carried out along with regular water tank and cooling tower inspections to ensure the associated water systems remain safe.

Had a cold water tank in the loft full of dust, wasp and flies. Tanks were cleaned to a very good standard, considering the awkwardness of the job. Very happy with the service

We were carrying out plumbing works on a site in London where we discovered a badly leaking GRP water tank, the Echo Square Services team attended site as quickly as possible to repair the leak and reline the tank. We will definitely contact them next time we are faced with a similar issue - would highly recommend.

We had a heavily leaking metal water tank above our office which was leaking through our ceiling, Echo Square Services repaired the leak and relined the tank just two days after we made the enquiry!

Arrived very quickly when the crisis developed in the 100-year-old water tanks in this Grade 1 listed building; did what looks a highly professional job (re-lining two hard to get at tanks in the roof) all in one day - which involved working really late - and were careful to make no mess and cause no damage. So far, it looks a great job at a reasonable cost.

Having used other companies in the past I can wholeheartedly say that our dealings with Nationwide Tank Relining have been a breath of fresh air. We have had tanks relined, water hygiene assessments and floor coatings. All work was carried out in a timely manner and the quality of work has each and every time been exemplary. My bosses are thrilled with my decision to switch to Nationwide Tank Relining and a tank that was relined 10 years ago by them still looks good as new internally, and the money we've saved from choosing the right supplier has proven to be a very smart business move. Highly recommended!
