The water for cooking sweets, puja and your guests&#8217; drinking all comes from the tank. Diwali and Kali Puja fall on 8 November 2026. An overhead tank takes about 40 to 60 minutes to clean and an underground tank 1 to 1.5 hours, so book a few days early.<\/div>\n\n\n\n<div lang=\"bn\" style=\"background:#FFF8E7;border-left:5px solid

You wash the curtains, clean the fans, paint the walls and light up the balcony. In Kolkata, many families also prepare for Kali Puja on the same night. But one thing often gets missed: the water tank on the roof, or the one under the building.<\/p>\n\n\n\n<h2 id=\"why-tank\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_should_the_water_tank_be_on_your_Diwali_cleaning_list\"><\/span>Why should the water tank be on your Diwali cleaning list?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Almost every part of the festival uses water from your tank:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cooking sweets, snacks and bhog in the kitchen<\/li>\n\n\n\n<li>Washing the puja items and the puja room<\/li>\n\n\n\n<li>Bathing before the puja<\/li>\n\n\n\n<li>Drinking water and tea for your guests<\/li>\n\n\n\n<li>Extra washing and cleaning all week<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">More guests means more water. If the tank is dirty, that dirt reaches every glass and every plate. Water tank cleaning before Diwali makes sure the water is as fresh as the rest of your home.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diwali celebrates light over darkness. As we light diyas to welcome Maa Lakshmi, and as Bengal prays to Maa Kali for protection, it feels right that the water your family uses every day is clean too. The inside of a water tank stays dark all year. At the end of a professional clean, UV light from a UV-C lamp reaches into that darkness and kills the germs left behind.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/srsfms.in\/blog\/wp-content\/uploads\/2026\/11\/diwali-family-rooftop-water-tank-srs-kolkata.webp\" alt=\"Water tank cleaning before Diwali: illustration of a family celebrating Diwali on a Kolkata rooftop beside clean water tanks\" class=\"wp-image-75\" srcset=\"https:\/\/srsfms.in\/blog\/wp-content\/uploads\/2026\/11\/diwali-family-rooftop-water-tank-srs-kolkata.webp 1200w, https:\/\/srsfms.in\/blog\/wp-content\/uploads\/2026\/11\/diwali-family-rooftop-water-tank-srs-kolkata-300x169.webp 300w, https:\/\/srsfms.in\/blog\/wp-content\/uploads\/2026\/11\/diwali-family-rooftop-water-tank-srs-kolkata-1024x576.webp 1024w, https:\/\/srsfms.in\/blog\/wp-content\/uploads\/2026\/11\/diwali-family-rooftop-water-tank-srs-kolkata-768x432.webp 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">Illustration: clean water, bright home.
