Water Tank Cleaning and Disinfection
Professional cleaning and disinfection of water tanks and reservoirs removes sediment, biofilm and microorganisms to protect water quality.
Over time, sediment, rust, biofilm and microorganisms build up in water tanks and reservoirs, even when the incoming water is clean. Periodic cleaning and disinfection keep stored water safe and protect the health of building users.
When Is Cleaning Needed?
Tanks should be cleaned and disinfected periodically, after construction or repair work, after long periods out of use, and whenever water quality complaints or positive microbiological results occur.
Our Process
- Isolating and draining the tank
- Removing sediment and mechanical cleaning of walls, floor and fittings
- Rinsing and removal of cleaning residues
- Disinfection with an approved disinfectant at the correct concentration and contact time
- Final rinse, refilling and checking residual chlorine
- Optional water sampling for laboratory analysis and a service report
Where We Work
Hotels, residential complexes, hospitals, schools, factories, food facilities and public buildings.
Prevention
Proper tank covers, ventilation screens, regular inspection and, where needed, automatic chlorine dosing reduce contamination between cleanings.
