Our underground tanks are built to preserve water in its most natural state, ensuring dependable supply for residential, commercial, agricultural, and industrial applications.
What is an Underground Sump Tank?
An underground sump tank is a large water storage tank installed below ground level to collect and store water from multiple sources such as:
- Municipal water supply
- Borewell water
- Rainwater harvesting systems
- Stormwater drainage systems
From the sump tank, water is pumped to overhead tanks or distribution systems for daily use.
Underground sump tanks are widely used in homes, apartments, hospitals, factories, hotels, and agricultural facilities where reliable water storage is essential.
Why Choose Underground Sump Tanks from Ocean Group?
Ocean Group sump tanks are designed to combine strength, hygiene, and efficiency while meeting modern water storage requirements.
1. Space-Saving Installation
Underground sump tanks are installed beneath the surface, allowing you to utilise valuable outdoor space efficiently. Gardens, parking areas, and building landscapes remain unobstructed while water storage stays hidden and protected.
This makes sump tanks an ideal solution for urban homes, villas, commercial complexes, and apartment buildings.
2. Superior Strength with Premium LLDPE Construction
Ocean Group sump tanks are manufactured using high-grade Linear Low-Density Polyethylene (LLDPE), providing:
- High impact resistance
- Structural stability under soil pressure
- Long operational life
- Leak-proof performance
The robust structure ensures the tank remains stable even under heavy loads and soil compression.
3. Protection from Heat and UV Exposure
Unlike exposed water tanks, underground sump tanks are naturally shielded from:
- Direct sunlight
- Extreme temperatures
- UV radiation
This protection helps maintain cooler water temperatures while preventing material degradation and extending the life of the tank.
4. Hygienic Water Storage
Maintaining water purity is essential for health and safety. Ocean Group sump tanks are designed to reduce contamination risks by protecting stored water from:
- External pollutants
- Algae growth caused by sunlight
- Environmental debris
The sealed and durable structure ensures clean and safe water storage for domestic and commercial use.
5. Ideal for Rainwater Harvesting Systems
Underground sump tanks are a vital component of rainwater harvesting systems. They efficiently collect and store rainwater from rooftops and drainage channels.
Stored rainwater can be used for:
- Garden irrigation
- Household cleaning
- Groundwater recharge
- Agricultural activities
This helps reduce dependency on municipal water supply and promotes sustainable water conservation.
6. Floodwater and Drainage Management
In areas with heavy rainfall, sump tanks can function as part of stormwater drainage systems.
They help:
- Collect excess surface water
- Prevent water accumulation in low-lying areas
- Reduce flooding risks around buildings
This makes sump tanks especially valuable in monsoon-prone regions of South India.
7. Long Service Life with Low Maintenance
Ocean Group sump tanks are built for durability and require minimal maintenance. Their corrosion-resistant material ensures the tank remains functional for many years without structural damage or leakage.
This reliability makes them suitable for:
- Residential properties
- Industrial facilities
- Commercial buildings
- Institutional infrastructure
8. Cost-Effective Water Storage Solution
Although underground tanks require initial installation, they provide long-term cost advantages by:
- Reducing water wastage
- Supporting rainwater harvesting
- Lowering reliance on tanker water supply
Over time, this results in significant savings on water expenses.
