Ashirvad 3 Layer Overhead Tank is a rooftop water storage tank built with three layers for safe, clean water. The inner layer is made from food-grade virgin plastic for hygienic storage, the middle layer blocks sunlight to help prevent algae growth, and the white UV-stabilised outer layer reflects heat and protects the tank from sun damage – helping keep stored water cooler and the tank lasting longer.
The seamless rotomoulded body has no joints or weak points where leaks could start. The tank comes without pre-drilled holes: instead, it has flat, pre-marked spots at the top (for inlet and overflow) and bottom (for outlet and drain), so your plumber can drill holes to suit your pipe size and layout. ISI marked and backed by Ashirvad's 10-year warranty, it suits homes, apartments, offices and commercial buildings across Bangalore & Hyderabad.

Installation Guidelines
- Prepare the Platform: Build a level concrete platform at least 4 inches high, extending 6 inches beyond the tank base on all sides
- Place the Tank: Position it centrally and check it is level with a spirit level
- Drill the Holes: Drill inlet, outlet, overflow and vent holes only on the pre-marked flat spots, using a multi-saw cutter (hole saw) for holes up to 2 inches
- Fit Connections: Fit tank nipples with rubber gaskets on both sides, then connect valves and pipes using PTFE tape for leak-free joints
- Do Not Anchor: Don't bolt the tank to the platform – it needs room to expand and contract
- Test: Fill slowly, check all joints for leaks, and clean the inside before regular use
Important: Never use a heated iron rod or chisel to make holes – it can crack the tank and void the warranty.
1) Does the tank come with inlet and outlet holes?
No. Ashirvad overhead tanks don't have pre-drilled holes. They have flat, pre-marked spots at the top (inlet and overflow) and bottom (outlet and drain), where your plumber drills holes to suit your pipe size and layout. Use a hole saw for holes up to 2 inches – never a heated rod or chisel, as this can crack the tank and void the warranty.
2) What fittings do I need to buy separately?
Tank nipples with rubber gaskets on both sides, ball valves and unions for the inlet, outlet, overflow and air-vent pipes, plus the pipes themselves.
3) Why choose a 3-layer tank over a single-layer tank?
The middle layer blocks sunlight to help prevent algae, the UV-stabilised outer layer resists sun damage, and the white surface reflects heat to help keep water cooler – making 3-layer tanks better suited to rooftops in strong sunlight.
4) What capacity do I need?
Plan for about 150 – 200 litres per person per day. A family of 4 typically uses 600 – 800 litres a day, so the 1000 L tank suits most families. If your water supply is irregular or you need 2 – 3 days of backup, choose the 1500 L or 2000 L tank.
5) Can I place the tank directly on the roof slab?
No. Always use a concrete platform raised 4 – 6 inches above the roof. It keeps the base dry, lets water drain away and protects the tank bottom from heat and moisture.
6) How often should I clean the tank?
At least twice a year, ideally before and after the monsoon. Drain it fully, scrub the walls, rinse, and disinfect with a diluted bleach solution before refilling. In areas with high sediment, clean every 3 months.
