Water Hygiene within Domestic Water Systems

Professional Water Hygiene solutions for domestic systems in Scotland – Disinfection, Compliance, and Bacteria Risk Prevention

Domestic water systems can harbour harmful bacteria if not properly maintained.

Stagnant water in peripheral parts of a system, such as unused outlets and dead legs, can encourage bacterial growth, posing health risks, particularly with pathogens like Legionella.

To mitigate these risks, all domestic hot and cold water systems should be thoroughly cleaned, flushed, and disinfected BS EN 806-4:2012 and BS 8558:2015.

Our Water Hygiene and Disinfection Process

Phoenix Commissioning Systems follows stringent guidelines for water system hygiene, to ensure every domestic water system is sanitised effectively. Our process includes:

Disinfection
We add a disinfectant, such as hydrogen peroxide, drawing it through the entire system. The disinfectant remains for a specified contact time to neutralise harmful bacteria effectively. Residual chemical levels are monitored at selected outlets to ensure effective disinfection.

Thermal Balancing of Hot Water Return Pipework
Proper circulation within the hot water return pipework is crucial for safe and efficient operation of any domestic water system. This also benefits the users by ensuring a quick heat up time of outlets whilst also minimising bacteria growth.

Setting and Validation of Mixing Valves and Balancing Valves
Thermostatic mixing valves (TMVs) play a vital role in regulating water temperature and flow. We validate these components to maintain an optimally safe and efficient system.

In addition to disinfection, Phoenix Commissioning Systems offers comprehensive validation of domestic water services for clients all over Scotland. Contact us to find out how we can help.
