Turn any faucet into a Green Bouquet tap.
An ARK tap aerator cuts water use by 40 to 60% without losing pressure. Use the free calculator below to see how many litres you save at your water pressure - and what that comes to on your water bill.
Your setup
Flow rates read from the catalogue at the pressure you set.
Most Indian homes run 0.5-3 bar (rooftop tank). 4-5 bar needs a pressure pump or high-rise supply.
What you save
| Pressure (bar) | Unrestrained (LPM) | Regular (LPM) | Special (LPM) |
|---|---|---|---|
| 0.5 | 13 | 6 | 3 |
| 1 | 18 | 8 | 6 |
| 2 | 25 | 12 | 6 |
| 3 | 30 | 14 | 6 |
| 4 | 35 | 16 | 6 |
| 5 | 39 | 18 | 6 |
Savings shown are estimates based on catalogue flow data and typical tap behaviour. Actual savings vary with your plumbing, pressure and usage.
Tap aerators & water saving - your questions answered
A water-saving tap aerator is one of the cheapest ways to cut household water use in India. It screws onto any existing tap, mixes air into the stream, and reduces water use by 40 to 60% without losing pressure. Here is how ARK e-Aqua Tech aerators work, how much they save, and what to expect.
A water-saving aerator is a small screw-on nozzle that fits the end of any tap. It mixes air into the water stream, so the flow still feels full and strong while using far less water - typically cutting tap water use by 40 to 60%.
An ARK aerator usually cuts a tap's water use by 40 to 60%, depending on your water pressure. A standard tap flowing 10 litres per minute drops to around 6 LPM with a 6 LPM pressure-compensating aerator - saving thousands of litres a year per tap. Use the calculator above to see the litres for your own setup.
No. That is the point of an aerator - it reduces the volume of water, not the feel of the pressure. By blending air into the stream it keeps the spray strong and splash-free while less water actually flows, so washing hands or dishes feels the same.
A pressure-compensating aerator holds a steady flow rate even when your water pressure changes. ARK's 6 LPM (H6) model keeps the flow flat at about 6 litres per minute whether pressure is high or low, which makes savings predictable across floors of a building and in rooftop-tank Indian homes.
India's Jal Jeevan Mission, the national programme for household tap connections, sets a benchmark of 55 litres per person per day for rural supply. It is a useful yardstick for any home: an ordinary tap running unrestrained at about 18 litres per minute gets through one person's daily 55 litres in roughly three minutes. Fitted with a 6 LPM pressure-compensating aerator the same tap takes over nine minutes to use the same water - which is why flow control at the tap matters as much as how long it runs.
In most cases yes - ARK aerators screw onto the standard threads found on the vast majority of Indian taps, with no plumbing or tools beyond a hand-tighten. The Green Bouquet range covers common sizes; add the model you want to an enquiry and the ARK team will confirm the fit.
An aerator costs a few hundred rupees and starts saving water from the day it is fitted - typically thousands of litres per tap per year. How fast that repays the cost in rupees depends on your water tariff, which varies widely across India and is subsidised in many cities, so it can range from months to a few years. The calculator above estimates both the litres saved and the payback for your own tariff.
