Closed Systems and the Importance of Water Treatment
Closed circuit or closed loop water system is a pipework design that enables water to be circulated for either heating or cooling purposes in domestic, industrial or commercial premises.
Without an effective water treatment programme corrosion products, foulants and slime forming bacteria can build up in the system. The components of the system will become blocked or decay resulting in a reduction in heat transfer issues and a lot of expense.
Pre-commission cleaning of closed circuit pipework systems and the subsequent monitoring of water quality are essential in any building. The implications of getting these wrong can be catastrophic. The resulting problems include disruption to occupants whilst systems are re-cleaned or, in the worst cases, complete closure of buildings whilst entire systems are ripped out and replaced due to early failure.
Further problems may arise when existing pipework is altered or replaced within a section of a building, e.g. in a large office building split into smaller units. Once the contractor has completed any modification works in a unit, the system has been flushed and re-connected to the mains, water starts to circulate between the modified pipework and the existing. If the results of the sampling prior to re-connecting have picked up any bacteria, such as Pseudomonas, Nitrite Reducing Bacteria, Sulphate Reducing Bacteria or Iron Bacteria, this then may enter into the main pipework and pollute the whole pipework system. It is therefore very important to sample the water in the mains before and after any fit-out works to eliminate the risk of spreading and contaminating the whole circuit.

Water Quality Services
Water quality services are all about making sure water is safe and clean for everyone to use. We use accredited laboratories to test samples for things like chemical balance and dissolved oxygen. This helps us identify any nasty pollution incidents before they become a big problem. By looking at data from our monitoring equipment, we can spot issues quickly and suggest ways to improve water quality. This service is really important for protecting public health and ensuring that our natural water resources are looked after properly for the future.
Commercial Protection with Water Sampling during Fit Out Works
The water quality within commercial, public health and other large premises can be problematic to property owners, developers, contractors and all parties with responsibilities for the operation of the building and the longevity of pipework and plant.
Water conditions within closed systems are especially important and unless controlled can allow pipework and plant conditions to deteriorate – or operational problems can occur as a result of fouled water.
When properties change hands it can also lead to disputes over responsibility for the cause of contamination and the fees to eradicate it from affected systems.
Before purchasing a property, undertaking a Fit Out, taking on a new maintenance contract or altering pipework in closed systems (heating, chilled etc) it is advisable to have a full set of water samples taken in order to assess the water quality. On occasions, water sampling of open systems is also important. This allows timely and appropriate remediation in the event that it is necessary. Additionally this can allow new building owners to assess the risks associated with water systems before finalising on a purchase.
Newly installed closed systems, LTHW, MTHW, HTHW, Chilled Water and Condenser Water circuits should generally be pre-commission cleaned. The vast majority of these systems have small regulating valves, which readily become blocked with particulate matter and would then fail to operate. It is therefore very important to ensure the presence of acceptable water quality prior to putting the system into use. Debris that is present in a system as a result of the installation process needs to be removed.
BSRIA BG29-2021 ‘Pre-commission Cleaning of Pipework Systems’ outlines the methodology for cleaning new systems. In addition this guidance outlines the responsibilities of designers and installing contractors.
We strongly recommend that pre-commission cleaning works are fully recorded and witnessed and that samples are taken to demonstrate cleanliness on completion. In addition we recommend that samples are taken at practical completion on a building site contract to demonstrate compliance with the specification for the new building.
Benefits of Water Quality Monitoring Services
There are many benefits to using professional water quality monitoring services for your building or site. By helping organisations understand their water use, we can make sure that wildlife and local habitats are kept safe from harm.
Cost Effective
Using our services is actually a very cost effective way to manage your building’s water systems. If you ignore small problems now, they can turn into huge, expensive repairs later on. By using data loggers and careful assessment, we can spot issues before pipes get blocked or damaged. This saves money on maintenance and parts in the long run. It is much cheaper to fix a small issue today than to replace a whole system tomorrow. Investing in good monitoring saves cash and protects your investment.
Closed Systems Monitoring
In line with industry and British standards BS 8552 (2015) we carry out the water sampling, testing and monitoring of LTHW systems (Low Temperature Hot Water), Medium Hot Water systems, Condensers and Chilled Water systems. Various regular checks can be performed to ensure the on-going chemical protection of the installation is adequate and microbiological control is maintained.
We use state-of-the-art quality sampling analysis equipment to assure that your water system meets the necessary guidelines, and we can quickly identify and resolve any issues that could be causing water quality to drop below required standards. We have a network of independent UKAS accredited laboratories at our disposal which are utilised for a range of quality sampling analysis, ensuring we provide accurate and reliable results for all of our sampling analysis.

Closed System Sampling
Sampling closed systems is a bit different from checking a tap, but it is just as important. We take small amounts of water from heating or cooling pipes to see what is going on inside. This helps us spot if there is rust or sludge building up that you can’t see from the outside. It is a reliable way to check on the health of your system without taking it apart. Regular checks like this can stop breakdowns and keep your heating or cooling working efficiently.

Frequently Asked Questions
Which sampling method is used in water?
Water sampling methods can vary depending on the type of system being analysed and the specific objectives of the sampling. Generally, we use grab samples and composite samples. Grab samples are collected at a single time and typically reflect the water quality at that instant, making them helpful in identifying short-term, acute issues. Composite samples, on the other hand, are collected over a period and combined to provide an average representation of water quality. This method is beneficial for understanding longer-term trends and variations. Our standard procedures align with British standards and industry best practices, ensuring that all samples are representative and reliable.
What are the two types of water sampling?
The two types of water sampling are grab sampling and composite sampling.
- Grab Sampling: This technique involves collecting a single sample at a specific point in time from a particular location. It’s beneficial for identifying the water quality at the exact moment of sampling, which can help pinpoint and address immediate concerns or contamination events. This method is often utilised for regulatory compliance and when conditions in the water system are expected to be relatively uniform.
- Composite Sampling: In contrast, composite sampling involves collecting and combining multiple samples into one sample representing the average water quality over that time frame. This method is beneficial for assessing longer-term trends and fluctuations in water quality, providing a more comprehensive overview of the water system’s status. Composite samples are often used when water quality varies throughout the day or over various conditions.
What 3 factors are monitored for water quality?
- Chemical Composition: Monitoring the chemical composition of water is crucial for understanding its quality and suitability for various applications. Parameters such as pH, alkalinity, hardness, and the presence of specific ions like chloride, nitrates, and sulfates are commonly analysed. These chemical factors help assess the corrosivity, scaling potential, and overall chemical stability of the water, which are vital for maintaining the integrity of pipework and plant systems.
- Microbiological Content: The presence of microorganisms, including bacteria, algae, and fungi, is another critical factor in water quality monitoring. Specifically, tests for coliforms, Legionella, and other pathogens are conducted to ensure the water is safe from microbiological contamination. Effective microbiological control is essential to prevent biofouling, which can lead to operational issues and health risks.
- Physical Characteristics: Physical attributes such as temperature, turbidity, colour, and the presence of suspended solids are also monitored. High levels of turbidity or suspended solids can indicate the presence of particulate matter that could obstruct pipes and valves. Monitoring these physical characteristics helps maintain the water system’s operational efficiency and identify any immediate remediation needs.
What are the chilled water testing parameters?
When we test chilled water, we look at many specific things to make sure the system is in good condition, such as pH level to ensure the water isn’t too acidic, this could corrode pipework. We also look for dissolved oxygen, because too much oxygen causes rust. We test for bacteria too, to stop slime from growing and blocking the flow. Finally, we check the levels of inhibitor chemicals to make sure the system is properly protected against damage.
What is a good water quality monitoring system?
A really good water quality monitoring system is one that watches over your water all the time. It should use smart sensors to track changes in real time so you know exactly what is happening. The best systems are reliable and send alerts if something goes wrong, like a sudden drop in quality. It should be easy to use and help you stay compliant with the Water Framework Directive. Basically, it gives you the control you need to manage your water confidently.
