The Best Time to Clean Your Water Tank in Jordan: A Seasonal Guide

In Jordan, the climate features hot dry summers and cold rainy winters — both of which impose different conditions on water tanks. Knowing the optimal cleaning time makes the interval between two cleanings more beneficial and less wasteful.

Why Right Before Summer (April – May)?

• Heat greatly accelerates the growth of bacteria and algae — a clean tank starts summer with better resistance
• Consumption rises in summer, and cleaning a full tank after use is harder
• Mild spring temperatures make the technicians’ work easier and ensure complete drying after cleaning
• Avoiding the health emergencies that intensify in summer due to contamination

And Why Before Winter Too (September – October)?

• The first rains carry concentrated contaminants from rooftops and pipes — a clean tank receives them more safely
• Winter humidity activates fungi inside the tank if it hasn’t been cleaned beforehand
• Winter water outages leave the tank empty for longer periods, concentrating sediment
• Cold weather slows disinfectants — so cleaning before the cold is more effective

The golden rule in Jordan: two cleanings a year — April before summer, and October before winter. This timing matches the nature of our climate perfectly.

Are There Times to Avoid?

It’s best to avoid cleaning at the peak of summer (July – August) if possible, because the intense heat evaporates disinfectants quickly before they finish their work and makes complete drying harder. If you must clean during this time, choose the early morning hours.

What About Underground Tanks and Wells?

Underground tanks and wells are less affected by temperature than rooftop tanks, but they’re more prone to contamination from rainwater and ground seepage during winter. So it’s recommended to clean them once in spring after the rainy season ends.
