Water Treatment & System Remediation services by Jordan Environmental


Building Services Professionals are usually aware of the need to establish maintenance regimes on the mechanical components of heating and chilled systems, but sometimes neglect the largest system component and the most key element of the heat transfer process – THE WATER!

The word ‘cleaning’ often suggests a ‘low tech’ requirement.

The opposite is true.

System and component knowledge, fluid dynamics, physics, chemistry, biology, safety and logistics all come into play, with experience possibly taking precedence.

Regular expert analysis and technically correct water treatment will not only serve to protect and maintain the efficiency of the system, but will also give early indication of significant issues. Without this, the potential ‘whole’ costs of system failure caused by corrosion, erosion, MIC, lime-scale or iron oxide sludge, will eventually and inevitably emerge, with the likely requirement for convoluted chemical regimes or remediation by ‘system cleaning’.

Reassuringly, water chemistry and the processes of system contamination remains fairly constant, but development of renewable systems can throw up new challenges. For example, we are developing with the ongoing treatment of Solar Thermal in particular, due to the issues of ‘cracked’ Glycol within these systems.

Our expertise is also coupled with high quality reporting standards, and never more so than when completing Pre-Commission Cleaning and Disinfections to BSRIA BG29, BSI and Water Authority standards. Testing for NRB, SRB, and pseudomonads will often form part of the extensive quality validation that accompanies these projects.

Jordan Environmental can draw on the practical knowledge that comes from over 20 years of operation in this specialist Environmental Building Services sector, allowing us to assess and deliver credible, achievable and effective service solutions within our client’s buildings.

Important information regarding COVID-19 Pandemic


The following is not intended to add further anxiety to an already bad situation but is factual advice that Building Services Professionals should already be aware of, but which is worth repeating.

We are working in unprecedented and extraordinary times with the way that the Coronavirus Virus (Covid-19) Pandemic has suddenly impacted on all aspects of our lives.

It is therefore understandable that a majority of companies, organisations and institutions are focussing on their own strategies of operation and protection. At Jordan Environmental Ltd we are facing the same challenges.

A totally understandable reaction to the current Covid-19 issue is to close to all ‘outsiders’ but this ignores a foundation principle of COSHH and risk reduction.

The mitigation of one risk could be creating another.

This is what happening with Water Hygiene aspects.

We urge those responsible for the Building Water Services to consider this aspect when reducing occupancy levels or closing buildings, as the risk from waterborne bacteria, including Legionella, will become elevated as the risk of Covid-19 is reduced.

The mitigation of one risk could be creating another.

Information regarding COVID-19 Pandemic

Bacteria inevitably colonise water systems and when these become irregularly used or mothballed in increasing levels of ‘Lockdown’, the bacteria will start to multiply.

The approach of the Spring and Summer, with higher ambient temperatures creating tepid water temperatures, will create ‘the perfect storm’!

We highly recommend that existing water hygiene regimes should be continued and as well as introduction of other additional aspects that can be undertaken by site staff.

Not every aspect of our service provision would be considered as ‘essential’ but ongoing legionella control and prevention is! This is recognised by leading professional organisations.

Please allow us to attend to your sites where at all possible. Our Water Hygiene Technicians are all well aware of risk levels and the practice of safe procedures.

We are here to assist and will be remaining open at all times for contact and advice, as a minimum.

The one certainty that is undeniable right now is uncertainty itself, so we at Jordan Environmental remain supportive to all clients and associates and wish you all Good Luck and Good Health at this time.

Yours sincerely
Alan Jordan
Managing Director
