Founded in 2017, Bauddha Tank Cleaning has spent more than seven years cleaning water tanks, clearing drains, and repairing pipelines for homes, offices, hotels, and apartments across Kathmandu. What started as a small local team in Kathmandu, Lalitpur, and Bhaktapur has grown and now serves customers throughout the Valley, and a large share of them are repeat customers who book us every six months.
