Källa connects to your rainwater, say from a barn roof — running down the gutter and downpipe into a water butt, and that stored water feeds straight into your Källa. Yours might look different; the collection side stays yours, and we build Källa to fit it.
The living filter. Pour your rainwater in to top it up; a living layer of microbes — a community of beneficial bacteria and other tiny life that settles on the sand and does the cleaning, the same natural process that keeps a healthy riverbed clear — and a deep bed of fine sand traps the rest. Cleaned water trickles out the bottom into the storage tank.
“No filters to replace.
It gets better with age.”
The filtered water trickles into a covered storage tank — a buffer that keeps a steady supply on hand, so the UV reactor never runs dry. Use it fresh: treated water is best drunk soon after — don't let it sit longer than you need.
The UV reactor — water from the storage tank flows in and a burst of UV-C — the same clean wavelength in sunlight that keeps natural water clear — neutralises anything the sand didn't catch, viruses included, so only safe water flows out. It uses no chemicals at all — none added, none needed — and runs on the sun.
Fill your glass straight from the UV tap — drawing water through it keeps the storage tank turning over. Each unit makes 60–80 litres a day — plenty for a household.
“Your tap,
off the grid.”
