Water Tank Cleaning for Oil India Limited
Client: Oil India Limited
Eco Clean Technologies carried out a full NCIWC water tank cleaning at the Oil India Limited residential complex, covering both underground and rooftop overhead tanks — without emptying the tanks or requiring anyone to enter them.
The Challenge
Years of use had left the tanks coated with algae, mud, and silt at the base, raising the risk of contamination for residents relying on the tanks for daily water supply.
Our Approach
Our trained team used imported suction-based machines to clean the tanks entirely from outside, removing algae, sediment, and bacteria while saving most of the existing tank water — no tank was emptied or entered.
The Result
Tanks were restored to a clean, hygienic condition across the complex, with before/after photos confirming the removal of algae and sediment build-up.
