Rainwater Harvesting Filters by Talwin
Want to collect clean rainwater at home? Talwin offers the best rainwater harvesting filters in Bangalore. These filters clean the water coming from your rooftop by blocking leaves, dust and dirt before it enters your sump or recharge well.
We are trusted rainwater harvesting filter dealers, distributors and suppliers. Our filters work without power, are easy to install, and need very little cleaning — ideal for homes, apartments, schools, factories and offices. Rainwater harvesting is also mandatory for many properties under BWSSB rules in Bangalore.
How Does a Rainwater Harvesting Filter Work?
When it rains, water from your rooftop carries dirt, dry leaves and bird droppings. The filter cleans it before storage or recharge:
- Stage 1 — Vortex: the inlet water spins, throwing out leaves, twigs and heavier debris.
- Stage 2 — SS mesh: a fine 180–200 micron stainless steel mesh catches smaller dirt.
- Clean water flows to your sump, tank or recharge pit; debris is flushed out of the waste outlet automatically.
- A mosquito-proof screen prevents breeding inside the system.
This keeps your tank clean, protects your pumps and pipes, and maximises the water you save.

Frequently Asked Questions – Rainwater Harvesting Filters
Does the rainwater filter need electricity?
No. It works purely on water flow and gravity.
How often do I need to clean the filter?
Rarely — it is self-cleaning. A quick check every 2–3 months and before the monsoon is enough.
Can it handle heavy Bangalore rain?
Yes. It filters up to 1500 litres per minute, enough for heavy monsoon downpours on roofs up to 500 m².
Is rainwater harvesting mandatory in Bangalore?
Yes, for many properties. BWSSB rules require rainwater harvesting for larger existing sites and new buildings above the notified plot size, and non-compliance can attract a penalty on the water bill. Check the latest BWSSB notification or ask us.
Will it work with borewell recharge systems?
Absolutely. It keeps silt and leaves out of recharge pits so they don't clog.
Can we drink harvested rainwater?
Rainwater is naturally soft, but for drinking it should pass through a purifier (RO/UV) after this filter. The filter makes it clean enough for storage, bathing, gardening and washing.
What is the price of a rainwater harvesting filter?
Price depends on your roof size and number of downpipes. Call or WhatsApp us for a free quote.
