Tank Cleaning

Tank Cleaning / Jet Downs for Rainwater Storage tanks

How often should I clean my rainwater tank?

Some UK rainwater harvesting system manufacturers recommend that your rainwater storage tanks should be cleaned prior to the system being commissioned (prior to handover) and every 2-5 years thereafter. 

If the water is only being stored for toilet flushing and outside bib taps, British Standards for Rainwater Harvesting suggest your rainwater tanks only needs to be cleaned when ‘routine inspection show it to be necessary’. Have concerns over your water quality? We are here to help!

RTC can supply a tank clean package to suit your needs and budget regardless of whether you are a domestic or commercial customer. The operatives RTC send to site have the key skills, training and experience to carry out cleaning to a safe, thorough and professional standard.
