Our Story"},"content":{"rendered":"\n<p>Khan Tank Cleaning started in 2005 with one office in DHA Phase 2 and one idea: that cleaning water tanks should be a trade in its own right, done with proper equipment by people who do nothing else. Twenty years later we work from two branches and clean tanks for households, apartment buildings, schools, hotels and factories across the city.<\/p>\n\n\n\n<p>This is the Khan Tank Cleaning history in Karachi, told plainly: where we began, what changed in the city&#8217;s water over those years, what we learned from it, and how we work today.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2005: one office in DHA Phase 2<\/h2>\n\n\n\n<p>The company was founded by <a href=\"https:\/\/khantankcleaning.com\/mateen-khan\">Mateen Khan<\/a>, who still owns it and oversees quality control at both branches. In 2005 a tank in Karachi was cleaned, if at all, by a labourer with a rope and a brush. The job was treated as a chore, not a health measure, and nobody left a record of what had been done.<\/p>\n\n\n\n<p>The founding idea was to treat it as a specialist service instead. That meant three decisions which still define the company: do only tank cleaning, invest in equipment that removes what a brush cannot, and put the work in writing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The city&#8217;s water over the same twenty years<\/h2>\n\n\n\n<p>Our own story makes more sense set against what was happening to Karachi&#8217;s water. The need for clean storage grew every year, because the supply feeding it kept falling behind.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Year<\/th><th>What happened in Karachi&#8217;s water<\/th><th>Why it matters for stored water<\/th><\/tr><\/thead><tbody><tr><td>2005<\/td><td>Hub and Pipri III treatment plants commissioned, the last major additions to filtration capacity listed by KWSC<\/td><td>Treatment capacity has barely grown since, while the population has<\/td><\/tr><tr><td>2012<\/td><td>First recorded deaths in Karachi from Naegleria fowleri, the amoeba linked to unchlorinated water<\/td><td>Put household tanks and chlorination on the public health agenda<\/td><\/tr><tr><td>2016 to 2018<\/td><td>Drug-resistant (XDR) typhoid outbreak in Sindh; WHO counts 5,274 XDR cases, 69 percent in Karachi<\/td><td>Showed how far sewage contamination had entered drinking water<\/td><\/tr><tr><td>2017<\/td><td>PCRWR tests for a Supreme Court commission find 107 of 118 Karachi samples unsafe<\/td><td>The first widely reported citywide evidence<\/td><\/tr><tr><td>2023<\/td><td>KWSB reconstituted as the Karachi Water and Sewerage Corporation<\/td><td>Same network, new structure<\/td><\/tr><tr><td>2024<\/td><td>84-inch University Road main bursts; three weeks of disruption<\/td><td>Dirty first flow into thousands of tanks<\/td><\/tr><tr><td>2025<\/td><td>Five Naegleria deaths in Sindh; health department advises annual tank cleaning before summer<\/td><td>The first clear official guidance to households<\/td><\/tr><tr><td>2026<\/td><td>Repeated Dhabeji failures; K-IV still under construction<\/td><td>Supply remains at about 650 MGD against demand above 1,200<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The sources for these events are listed at the end. The supply system itself is explained in our <a href=\"https:\/\/khantankcleaning.com\/blog\/kwsb-water-supply\/\">guide to KWSB water supply<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The method, and what it replaced<\/h2>\n\n\n\n<p>Each part of the way we work answers a weakness in how tanks were, and often still are, cleaned in Karachi.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Jet washing in place of scrubbing.<\/strong> Brushes leave the slippery bacterial film on the walls. Water at 3,000+ PSI removes it, with reduced pressure for fibreglass and plastic.<\/li>\n\n\n\n<li><strong>Vacuum extraction in place of bailing.<\/strong> Sludge that is stirred and bailed mostly stays in the tank. A vacuum lifts it out and off the property.<\/li>\n\n\n\n<li><strong>A named disinfectant in place of bleach by eye.<\/strong> We use silver-stabilised hydrogen peroxide for routine work and food-grade chlorine for heavily contaminated tanks, and nothing unlabelled. The reasoning is in <a href=\"https:\/\/khantankcleaning.com\/blog\/silver-hydrogen-peroxide-tank-disinfection\/\">our article on silver hydrogen peroxide<\/a>.<\/li>\n\n\n\n<li><strong>Confined-space practice in place of &#8220;the boy goes down&#8221;.<\/strong> Forced ventilation and a gas check before entry, a harness and tripod, and a person at the hatch. Underground tanks kill people in Karachi every year.<\/li>\n\n\n\n<li><strong>A report in place of a handshake.<\/strong> Every job ends with a dated report, photographs taken inside the tank and a numbered tax invoice.<\/li>\n<\/ul>\n\n\n\n<p>Today those pieces form the <a href=\"https:\/\/khantankcleaning.com\/cleaning-procedure\">eight-step procedure<\/a> on our website, and <a href=\"https:\/\/khantankcleaning.com\/blog\/professional-tank-cleaning-karachi\/\">this article walks through a visit step by step<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Putting the business on a formal footing<\/h2>\n\n\n\n<p>Doing the work properly was half of it. The other half was being a company that customers, and especially institutions, could check.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Tax registration.<\/strong> We are registered with the Sindh Revenue Board and the Federal Board of Revenue and issue numbered tax invoices. What that means for a customer is covered in <a href=\"https:\/\/khantankcleaning.com\/blog\/srb-fbr-registered-company-karachi\/\">why SRB and FBR registration matters<\/a>.<\/li>\n\n\n\n<li><strong>ISO 9001 and ISO 45001.<\/strong> Under Mateen Khan&#8217;s leadership the company was certified to the quality management and occupational health and safety standards. <a href=\"https:\/\/khantankcleaning.com\/blog\/certifications-explained-iso-9001-iso-45001\/\">Our certifications explained<\/a> sets out what each one covers and how to verify a certificate.<\/li>\n\n\n\n<li><strong>Written prices.<\/strong> The quote is given before work starts and is the final price. Standard homes can get it from the <a href=\"https:\/\/khantankcleaning.com\/estimate\">online calculator<\/a>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Who we clean for<\/h2>\n\n\n\n<p>Most of our work is still houses and flats. Over the years we have cleaned more than 7,000 houses, 1,500 apartments and 650 industrial tanks. Alongside households, the organisations on our <a href=\"https:\/\/khantankcleaning.com\/client\">clients page<\/a> include Avari Towers, IBA, SZABIST, UBL, Mondelez, Shan Foods, SGS and Edhi Homes.<\/p>\n\n\n\n<p>Different clients need different things from the same job. A family wants clean water and a tidy courtyard. A factory needs a report its auditor will accept. A hotel needs the work done overnight. We have written separate guides for <a href=\"https:\/\/khantankcleaning.com\/blog\/industrial-water-tank-karachi\/\">factories and warehouses<\/a>, <a href=\"https:\/\/khantankcleaning.com\/blog\/hotel-water-tank-cleaning-karachi\/\">hotels and restaurants<\/a> and <a href=\"https:\/\/khantankcleaning.com\/blog\/apartment-water-tank-responsibility-karachi\/\">apartment buildings<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2025: a second branch in Gulshan-e-Iqbal<\/h2>\n\n\n\n<p>For twenty years we covered the whole city from DHA. Karachi is a large city to cross, and a second base in the east shortens the journey to a great many customers. In 2025 we opened at Suite-203, Mumtaz Manzil, Block 16, Gulshan-e-Iqbal.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Branch<\/th><th>Address<\/th><th>Phone<\/th><th>Main areas<\/th><\/tr><\/thead><tbody><tr><td><a href=\"https:\/\/khantankcleaning.com\/water-tank-cleaning-dha-clifton-karachi\">DHA and Clifton<\/a><\/td><td>Office-6, Plot-6-C, Phase 2, DHA, Karachi 75400<\/td><td>0333 0293174<\/td><td>DHA Phases 1 to 8, Clifton, Gizri, Seaview, Saddar, Korangi, Malir, Landhi<\/td><\/tr><tr><td><a href=\"https:\/\/khantankcleaning.com\/water-tank-cleaning-gulshan-jauhar-karachi\">Gulshan and Jauhar<\/a><\/td><td>Suite-203, Mumtaz Manzil, Block 16, Gulshan-e-Iqbal, Karachi 75300<\/td><td>0340 2717530<\/td><td>Gulshan-e-Iqbal, Gulistan-e-Johar, Nazimabad, North Nazimabad, Federal B Area, North Karachi, SITE, PECHS<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Both branches use the same procedure and both answer 24 hours a day, including Sundays and public holidays. How the two-branch structure serves customers is described in <a href=\"https:\/\/khantankcleaning.com\/blog\/trusted-water-tank-cleaning-karachi\/\">how we built a trusted tank cleaning service<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What twenty years have taught us<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Clear water proves nothing.<\/strong> Sludge sits on the floor and film on the walls while the water above looks fine. <a href=\"https:\/\/khantankcleaning.com\/blog\/water-tank-cleaning-karachi-results\/\">What we find inside Karachi&#8217;s tanks<\/a> describes the usual picture.<\/li>\n\n\n\n<li><strong>The underground tank is the one people forget,<\/strong> and the one that collects the most.<\/li>\n\n\n\n<li><strong>A filter is not a substitute for a clean tank.<\/strong> It treats one tap.<\/li>\n\n\n\n<li><strong>The lid matters as much as the cleaning.<\/strong> A tank with a broken cover is dirty again in weeks.<\/li>\n\n\n\n<li><strong>Schedules beat emergencies.<\/strong> Cleaning every four to six months prevents most of the urgent call-outs. See <a href=\"https:\/\/khantankcleaning.com\/blog\/tank-cleaning-frequency-karachi\/\">how often to clean a tank in Karachi<\/a>.<\/li>\n\n\n\n<li><strong>Safety cannot be optional.<\/strong> No job is worth sending someone into an unventilated tank.<\/li>\n\n\n\n<li><strong>Customers should not have to take our word for it.<\/strong> Before and after photographs settle what an explanation cannot.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">What we still cannot do<\/h2>\n\n\n\n<p>It is worth being honest about the limits. We cannot fix the supply. A tank we clean today will be refilled tomorrow with whatever the line or the tanker delivers, which is why we tell every customer to keep boiling or filtering drinking water. We do not carry out structural repairs, though we photograph and report every crack and corroded fitting we find. And we cannot make a tank stay clean without a lid that seals.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where we go from here<\/h2>\n\n\n\n<p>Karachi&#8217;s water shortage is not about to end. The K-IV project is still under construction, the network still loses more than half of what enters it, and households will be storing water for years to come. Our plan is unexciting: keep the method consistent across both branches, keep the paperwork straight, and keep explaining to customers what we find. This blog is part of that.
