Tank Clean & Chlorination – Apartment Block, Derby
Location: Derby
Service: Cold Water Tank Clean & Chlorination
Sector: Residential / Property Management
The Challenge
Our engineers were called to an apartment block in Derby to carry out a full clean and chlorination of the cold-water storage tank.
Regular maintenance had been overlooked, resulting in visible scale, sediment and bacterial risk buildup within the tank. To maintain tenant safety and water compliance, a thorough clean and disinfection were required.
Our Solution
The NT Cloke team carried out a full clean and chlorination in line with BS 8558 & ACOP L8 standards:
- The tank was drained, manually cleaned and descaled
- Biofilm and residue removed from internal surfaces
- Disinfection and flushing completed with chlorinated water
- System fully recommissioned and certified as compliant
✅ Full internal tank clean
✅ Disinfection and chlorination complete
✅ Certification issued on completion
The Result
The apartment block’s cold-water system is now clean, safe and fully compliant, ensuring residents have access to hygienic water supply and property managers remain aligned with water hygiene regulations.






Why It Matters
Tank cleaning and chlorination are critical to preventing the growth of Legionella and other harmful bacteria, particularly in large or shared residential buildings.
At NT Cloke Pumps & Water, we work closely with property management teams and landlords across the UK to ensure systems stay safe, efficient, and legally compliant.
