A concrete tank without weeks of site work
A precast tank is cast and cured in controlled conditions, then lowered into a prepared pit. That cuts site time to a few days and avoids the leakage problems that come from poor on-site curing and cold joints.
We supply precast tanks and also construct overhead and underground RCC tanks on site for larger capacities. Tanks are used for drinking water sumps, rainwater storage, septic tanks, chemical storage and industrial water.

FAQs
Precast RCC tanks: common questions
Can't find your answer? Ask us directly. We're happy to explain before you decide.
How much does a 10,000 litre concrete water tank cost?
A tank built on site costs roughly ₹15 to ₹20 per litre depending on location, with excavation extra. We confirm the price after a site visit.
What does a 5,000 litre tank cost?
A precast 5,000 litre tank costs about ₹15 to ₹17 per litre. Building the same capacity on site usually costs ₹20 to ₹25 per litre. Excavation is extra.
Is a precast tank as strong as a cast-in-place tank?
Our standard precast tank uses M30 concrete with two-way TMT reinforcement and carries a load of 10 tonnes. Because it is cured under controlled conditions, it is less prone to leaks from poor curing.
How long does installation take?
Once the pit is ready, a precast tank is placed and connected in a short time. Cast-in-place tanks take several weeks including curing.
Do you supply tanks outside Chennai?
Precast tanks can be supplied to other cities depending on transport access. Tell us the location and we will confirm.
Can a precast tank be used for drinking water?
Yes, with a food-grade inner coating and a proper cover and manhole. We recommend cleaning the tank before first use.
