Frequently Asked Questions — Industrial Tank Cleaning
Common questions about our industrial tank cleaning service
Are your teams trained for confined-space tank entry?
Yes. Our operatives are confined-space trained and we work to a confined-space risk assessment and method statement with permits, atmospheric monitoring, ventilation and standby rescue arrangements in place.
Do you clean cold water storage tanks?
Yes. We clean, disinfect and chlorinate cold water storage tanks to support water hygiene compliance, and we provide documentation for your records.
How do you dispose of residues and sludge?
We remove and dispose of residues, sludge and contaminants responsibly in line with waste regulations, providing the relevant documentation where required.
Will our process need to shut down during cleaning?
We plan tank cleaning around your operations to minimise downtime, often scheduling work during planned shutdowns or quieter periods. We'll agree the approach with you during the survey.
Do you provide documentation for compliance?
Yes. We provide pre- and post-clean inspection reports with photographic evidence, plus the relevant method statements and certificates for your compliance and audit records.
How often should industrial tanks be cleaned?
Cleaning frequency depends on the tank's contents and use. Water storage tanks are commonly cleaned annually, while process vessels follow their own maintenance schedules. We can advise during the survey.
