Importantly, CDI facilities goes beyond simple reporting and remediation  to identify key training needs for on-site personnel to ensure on-going compliance.


1. Legionella Risk Assessment

The first step to any water hygiene control programme is to undertake a risk assessment to establish the current site condition and highlight any existing potential risk areas.

The Legionella risk assessment will look at all aspects of a buildings water services and record the findings with detailed notes, including schematic diagrams and photographic records.

Finally, the risk assessment will provide straight forward recommendations on what actions need to be taken to reduce the risk and ensure compliance with water regulations.


2. Remedial Works

Remedial works after the Legionella risk assessment stage could include the removal of deadlegs, cold water storage tank upgrades or removal of old items of plant.

CDI Facilities can undertake most of these tasks for you using our own, fully qualified engineers, who specialise in the many fields of knowledge that are needed to understand a typical water system design.


3. Ongoing Monitoring

By using the information gained during the Legionella risk assessment process, CDI Facilities can firstly design a bespoke monitoring and testing regime based upon the guideline parameters laid out in ACOP L8.


4. Evaluation

Often undertaken on an annual basis, the evaluation of any water Legionella control programme is essential – this ensures the systems instigated are working effectively to help reduce the risk of contamination.


Water Treatment

The importance of an effective water treatment regime within any building can never be overstated. Properly designed and managed water treatment programmes not only ensure a system and the associated plant is operating effectively and cost effectively, but can also greatly increase the effective life span of the plant and reduce running costs.

CDI Facilities have developed a comprehensive and cost effective programme of water treatment solutions to not only ensure a system is operating in accordance with the latest guidelines but also to guarantee it stays that way; this comprises Routine Testing, Remedial Dosing, and Pre-Commission Cleaning stages.
