Sintex Underground Water Tank – FRP

FRP (Fibre Reinforced Plastic) water tanks are known for their long lifespan and durable construction. On average, a high-quality FRP tank can last 25 to 30 years or more with proper maintenance. These tanks are corrosion-resistant, leak-proof, and unaffected by rust or chemical reactions, which helps them stay strong even in harsh underground conditions.

Sintex FRP underground water tanks are built using premium materials that ensure high structural strength and long-term reliability. Regular cleaning and basic inspection of fittings are usually all that’s needed to keep them in good condition, making them a low-maintenance and long-lasting solution for commercial water storage.

Yes, FRP (Fibre Reinforced Plastic) tanks are designed to withstand extreme temperature variations without losing strength or shape. The material’s excellent thermal stability and insulation properties allow it to perform well in both very hot and cold conditions. Unlike metal tanks, FRP tanks do not rust, expand, or contract easily with temperature changes.

Sintex FRP underground water tanks are specially engineered to handle India’s diverse climate—from high summer heat to cold winters—while maintaining their leak-proof structure and durability. This makes them a reliable choice for long-term water storage across various environmental conditions.

Cleaning an underground water tank keeps your water safe and free from bacteria. Here’s a quick guide:

1- Drain the Tank: Pump out all the water using a motor or submersible pump.

2- Scrub the Interior: Use a brush or pressure washer with mild detergent or bleach to remove dirt, algae, and sludge.

3- Rinse Well: Wash away all cleaning agents with clean water.

4- Disinfect: Add a chlorine solution (about 50–100 mg/litre) and let it sit for 1–2 hours, then drain and rinse again.

5- Clean Pipes: Check and clean the inlet, outlet, and overflow pipes.

6- Refill: Close the tank lid properly and refill with fresh water.

Tip: Clean your tank every 6 months or hire a professional cleaning service for better results.

Underground water tanks are made from a variety of materials, each offering unique benefits depending on the application. The most common materials include FRP (Fiberglass Reinforced Plastic), concrete, polyethylene (plastic), and steel. FRP tanks are lightweight, corrosion-resistant, and long-lasting, making them ideal for residential and commercial use. Concrete tanks, on the other hand, are durable and suitable for large-capacity installations but can be difficult to maintain. Polyethylene tanks are cost-effective, easy to install, and resistant to rust or chemical reactions. Steel tanks offer high strength but require anti-corrosive coatings to prevent rusting. Among these, Sintex FRP underground tanks are preferred for their durability, leak-proof design, and resistance to soil and water pressure, ensuring safe and hygienic water storage for years.

An underground water tank should ideally be cleaned at least once every six months to maintain water quality and prevent contamination. Over time, sediment, algae, and bacteria can build up inside the tank, affecting both hygiene and water safety. Regular cleaning helps remove these impurities and ensures the stored water remains safe for use.

For commercial or high-usage properties, more frequent cleaning—every three to four months—is recommended. Using Sintex FRP underground tanks can reduce the cleaning frequency, as their smooth inner surface and non-corrosive design prevent dirt buildup and make maintenance easier and more efficient.

Yes, you can install an underground water tank in most soil types, but the soil condition plays an important role in determining the tank’s foundation and installation method. For example, rocky or clay-heavy soils may require additional excavation or reinforcement, while loose or sandy soils might need stronger base support to prevent shifting or settling over time.

Sintex FRP underground water tanks are designed for versatile installation and can adapt to a wide range of soil conditions. However, it’s always best to have a site assessment by a professional to ensure proper installation and long-term structural stability.
