Sump tanks are mainly used as water storage tanks for Residential and Commercial purposes. Most are constructed underground to store borewell water, so we can pump it to an overhead tank and use the Sump water for utility and gardening purposes. Keeping the sump clean and healthy is essential for our health and happiness.
