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.

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.

We manage a large residential block and recently reached out to Echo to quote to reline two water tanks that were failing. An absolute fantastic service all round. A quote was received within a day or so. Works were booked in and communication was excellent. We were really impressed with the engineers on the day. They communicated well on the day in terms of the plan of action. Once the work was complete, they ensured all areas were left clean and tidy. A follow up report post works was sent very soon after the works.We look forward to working with Echo again. If you need honest, reliable contractors who will get the job done and to a high a standard, don't hesitate to get in touch with them.Thank you.

I contacted Echo Square on behalf of a client of mine who urgently needed her Victorian underground Cistern re lined. The work was quoted for promptly and the work carried out to a high standard by the engineers who were courteous and friendly despite their long drive to site. My client was very impressed and so grateful to have her Cistern back in working order. I would highly recommend this company and will most definitely approach them again should I have another client with tank issues in the future. 5 star service!

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!
