Water Tank Cleaning

We provide professional, reliable and cost-effective water tank cleaning services for everything from large, complex commercial systems to small, domestic tanks throughout Northern Ireland.

The Importance of Water Tank Cleaning

At Techright, we understand the importance of clean and safe water. That’s why we offer professional and affordable water tank cleaning services for both commercial and residential systems. Over time, harmful bacteria like Legionella, as well as dirt, dust, and debris, can accumulate in water tanks. Regular inspections and cleaning are essential to maintain water hygiene and control the risk of Legionella.

Our services are in compliance with the Approved Code of Practice (ACoP L8/HSG274 Parts 1, 2 & 3) which requires clean conditions in all online water systems. Don’t let unclean water put your health at risk. Contact us today for routine tank inspections and cleaning to ensure your stored water is safe and compliant.

          How Often Should You Clean Your Water Tank? Expert Advice


To ensure the safety and cleanliness of your cold water storage tank, it is recommended to have it inspected and cleaned on an annual basis. However, the frequency may vary depending on the results of a site-specific legionella risk assessment. It is important to also keep an eye out for visible signs of sediment, stagnant water, biofilm, corrosion and flora growth during routine inspections, as this may indicate the need for a cleaning and chlorination.
