What Is Water Tank Cleaning and Disinfection?
Water tank cleaning and disinfection is the periodic draining, scrubbing and disinfecting of a building's water storage tank — the rooftop or basement depósito that holds mains water before it's distributed through the building — to remove sediment, biofilm and bacterial growth before it reaches the taps. In Spain, this is a legally required periodic maintenance task for shared building tanks, carried out to control the risk of Legionella and keep stored water safe.

Water Tank Cleaning
Valencia FAQ
Do you clean and disinfect water tanks in Valencia?
Yes. We drain, clean and disinfect rooftop and basement water storage tanks for apartment buildings, communities and private houses across Valencia and nearby towns.
+
Is water tank cleaning a legal requirement in Spain?
Yes, for shared building tanks. Spain requires periodic cleaning and disinfection of communal water storage tanks as a public health measure to control the risk of Legionella. We carry out the service and provide the paperwork your community administrator needs.
+
How often should a building's water tank be cleaned?
This depends on the tank type and the building's water usage, and your community administrator or management company will usually already have a required schedule. If you're not sure what applies to your building, message us and we'll help you work it out.
+
Will the building be without water during the cleaning?
There's a short period without stored water while the tank is drained and cleaned. We plan the work around low-usage hours where possible and keep the interruption as brief as we can.
+
Do you provide documentation for the community administrator?
Yes. After the service we provide a written record confirming the tank was cleaned and disinfected, which your administrator or property manager can keep on file.
+
What's involved in disinfecting the tank, not just cleaning it?
Cleaning removes visible sediment and biofilm from the tank walls and floor. Disinfection follows with a treatment left in contact for the required time to reduce bacterial growth, before the tank is flushed and refilled.
+
Do you work with community administrators and property managers?
Yes, regularly. We can liaise directly with a community administrator, property manager or landlord to schedule the service and hand over the paperwork afterwards.
+
Can you also service smaller domestic tanks, not just shared building tanks?
Yes. We clean and disinfect smaller private tanks in individual houses as well as the larger shared tanks in apartment buildings.
