PVC Water Tank Cleaning in Nagpur
PVC overhead tanks - the black or white Sintex-type tanks on most Nagpur rooftops - develop algae growth on interior walls and sediment accumulation at the base, both of which affect the taste and quality of the stored water. We clean PVC tanks of all sizes without requiring the tank to be removed or replaced.
PVC Tanks Develop Algae and Sediment Faster Than Most Owners Realise
Black PVC tanks allow some light penetration through the plastic, particularly as the material ages and thins, which creates ideal conditions for algae growth on the interior walls. The combination of light penetration, standing water and Nagpur summer heat (which raises water temperature in rooftop tanks to levels that encourage microbial growth) makes algae a common problem in tanks that have not been cleaned in 6-12 months.
Beyond algae, the sediment that enters through the inlet pipe - fine sand and rust particles from ageing supply pipes - settles at the base of the tank and gets disturbed into the water supply whenever the tank is refilled or the outlet is opened. This sediment builds up into a visible sludge layer over time. The only way to remove it is to drain the tank fully and remove it manually before the scrub and disinfection step.

How PVC Tank Cleaning Works
Drain the Tank
Tank fully drained via the outlet or pump. We confirm the drain route before starting to avoid water damage below.
Manual Scrub
Interior walls and base scrubbed manually by hand to remove algae film and dislodge sediment from the base and wall surfaces.
Sediment Removal
Loosened sediment collected and removed from the tank. Outlet and overflow points checked for blockage.
Disinfect & Rinse
Food-grade disinfectant applied, allowed correct contact time, then fully rinsed before the tank is sealed and refilled. No chemical taste or smell in the water.
PVC Tank Cleaning Pricing in Nagpur
Pricing is for rooftop-accessible PVC tanks. Tanks with unusually difficult rooftop access or that require scaffold may be quoted slightly higher after assessment.
Why Book PVC Tank Cleaning With Harikrupa
Food-Grade Disinfectant Only
We use only disinfectants approved for potable water storage, followed by a full rinse before the tank is refilled.
Full Drain & Manual Scrub
We drain completely and scrub manually - not just a chemical flush which leaves sediment in place.
45-90 Minute Service
Most residential PVC tanks are cleaned in under 90 minutes including drain, scrub and refill setup.
Half-Yearly Reminder
We recommend cleaning every 6 months and can set a reminder so you do not have to track it yourself.
What Nagpur Residents Say
“Our tank had not been cleaned in over a year. After the Harikrupa clean the water immediately tasted cleaner and the algae smell on the walls was completely gone.”
“Two 1,000L tanks on our rooftop cleaned in the same visit. Quick, professional, no mess on the terrace. Will schedule again in 6 months.”
Frequently Asked Questions
How do I know my PVC tank needs cleaning?
Signs include discoloured water (yellow or green tint), a musty or earthy smell from hot water taps, visible slime or green film when you check inside the tank, or sediment visible in the water when it first runs.
How long does PVC tank cleaning take?
A standard 1,000L residential tank takes 45-75 minutes from drain to ready-to-refill. Larger tanks take proportionally longer.
Is the disinfectant used safe for drinking water?
Yes - we use food-grade disinfectants approved for potable water storage. The tank is fully rinsed after the disinfectant contact time to ensure no chemical residue enters the water supply.
How often should PVC tanks be cleaned?
Every 6 months is our recommendation for Nagpur rooftop PVC tanks, given the heat and light conditions that accelerate algae growth. Annual cleaning is the minimum.
