# Källa social copy pack Awareness-first voice: plain-spoken, curious, UK spelling, zero superlatives. Every factual claim traces to published kalla.me copy. Images are self-contained (WhatsApp needs no caption — forward the square PNG as-is). All the images live at kalla.me/materials.html — each post in square (Facebook / Instagram / WhatsApp), portrait (Instagram) and landscape (X) sizes. --- ## stat-zero — "Sixty systems built. Zero abandoned." **FB groups:** A water system is only as good as whether people keep using it. Of 60 systems built on this living-sand-and-sunlight design in remote South American communities, every single one is still in daily use — zero abandoned. The same approach is now being built for UK off-grid sites. We've put the whole rain-to-glass story at kalla.me if you're curious. **Instagram:** Sixty built. Zero abandoned. Every single system on this living-sand-and-sunlight design is still in daily use. Now built for UK off-grid sites → kalla.me #offgrid #offgridliving #smallholding #selfsufficiency #rainwaterharvesting #ecovillage #permaculture #homesteaduk #offgridwater #madeinbritain **X:** The hardest test of a water system isn't the lab — it's whether people are still using it years later. 60 built on this design. 0 abandoned. All still in daily use. kalla.me **Notes:** Strongest opener for a new audience. Pair with the square render; let the stat carry it. --- ## living-filter — "The only water filter that improves with age" **FB groups:** Odd question: what's the only water filter that gets better the longer you use it? A biosand filter — a living layer of helpful microbes on the sand does the cleaning, and a deep bed of fine sand traps the rest. No cartridges, nothing to replace, 10+ year filter life. It's the heart of the Källa system (kalla.me), but honestly the biology is worth knowing about either way. **Instagram:** Every other filter clogs and gets replaced. This one is alive — and it improves with age. No cartridges. Nothing to replace. 10+ years. → kalla.me #biosandfilter #offgrid #offgridliving #selfsufficiency #rainwaterharvesting #permaculture #smallholding #waterfilter #offgridwater #madeinbritain **X:** Every filter you've owned got worse with use. A biosand filter is alive — the microbe colony that does the cleaning gets stronger with age. No cartridges. 10+ years. kalla.me **Notes:** Best "huh, really?" educational share. Works well midweek; invites comments/questions. --- ## zero-receipt — "Running cost: £0" **FB groups:** We did the honest maths on running a Källa: chemicals £0, cartridges £0, filter replacements £0, mains water £0. Total: £0.00 a month — it runs on the rain on your roof and sunlight, and the filter lasts 10+ years. (The system itself is around £1,000, built bespoke to your site — running it after that is the £0 part.) kalla.me **Instagram:** Your water bill, itemised: chemicals £0 · cartridges £0 · mains £0 · sunlight £0 · rain £0. Running cost after setup: £0.00. Forever. → kalla.me #offgrid #offgridliving #selfsufficiency #rainwaterharvesting #vanlife #narrowboat #smallholding #homesteaduk #offgridwater #zerowaste **X:** Monthly running costs, itemised: Chemicals £0.00 / Cartridges £0.00 / Mains water £0.00 / Sunlight £0.00 / Rain £0.00 — TOTAL £0.00. Nothing to buy. Ever. kalla.me **Notes:** The most forwardable card (WhatsApp especially). If asked "what's the catch", the honest answer: ~£1,000 up front, a few minutes' care per top-up. --- ## rain-to-glass — "The rain on your roof is drinking water" **FB groups:** Genuine question for anyone collecting rainwater: what do you use it for? Most of us stop at the garden and the loo. With a living sand filter and a UV-C reactor it's safe drinking water — roof → living sand → UV-C → glass, no chemicals and no mains. We've drawn out the whole journey at kalla.me. **Instagram:** Roof → living sand → UV-C reactor → your glass. The rain you're already collecting is drinking water — you're just not treating it that way yet. → kalla.me #rainwaterharvesting #offgrid #offgridliving #selfsufficiency #permaculture #smallholding #ecovillage #waterbutt #offgridwater #madeinbritain **X:** The rain on your roof is drinking water. You're just not treating it that way yet. Roof → living sand → UV-C reactor → glass. No chemicals, no mains. kalla.me **Notes:** The thesis card. Good pinned post; also the natural caption-mate for the carousel. --- ## gravity-sunlight — "Powered by gravity and sunlight" **FB groups:** When the power cut hit last winter, what kept working at your place? A Källa doesn't notice: water falls through the filter by gravity, and the UV stage runs on 12 V solar with a battery. No pump, no chemicals, no mains anything. It keeps running when the grid doesn't. kalla.me **Instagram:** No pump. No chemicals. No mains. Gravity does the moving, sunlight does the disinfecting — 12 V solar + battery, day and night. → kalla.me #offgrid #offgridliving #solarpower #12v #selfsufficiency #vanlife #narrowboat #smallholding #offgridwater #resilience **X:** Powered by gravity and sunlight. No pump, no chemicals — 12 V solar and a battery. It keeps running when the mains and the grid don't. kalla.me **Notes:** Resilience angle — lands hardest after storms/power cuts. Keep it ready. --- ## comparison — "Four ways to drink rainwater. Only one does it all." **FB groups:** For everyone weighing up rainwater options, the honest comparison: reverse osmosis removes everything — including the minerals, which then need adding back — and eats replacement filters. Boiling clears pathogens but leaves the sediment and burns energy every time. Raw rainwater varies with your roof and the season. Living sand + UV does the lot, on rain and sunlight. Full table at kalla.me. **Instagram:** RO strips the minerals out. Boiling leaves the dirt in. Raw varies with the source. One way does it all — on rain and sunlight. → kalla.me #rainwaterharvesting #reverseosmosis #offgrid #offgridliving #selfsufficiency #waterfilter #permaculture #smallholding #offgridwater #madeinbritain **X:** Four ways to drink rainwater: RO (strips minerals, eats cartridges), boiling (leaves sediment, burns energy), raw (varies by source), or living sand + UV — which does it all on rain and sunlight. kalla.me **Notes:** Reference content — gets saved and shared in "which filter?" threads. Landscape render suits X best. --- ## numbers — "One unit. 60–80 litres a day." **FB groups:** Sizing question we get a lot: how much water does one unit actually make? 60–80 litres a day — plenty for a household's drinking and cooking. Communities scale by the unit: one covers roughly 15–40 people. Flow is ~0.4 L/min, gravity-fed, 12 V solar + battery, 99.9% filtration + UV-C, 10+ year filter. All the figures: kalla.me **Instagram:** The numbers: 60–80 L/day per unit · 10+ yr filter life · 99.9% filtration + UV-C · 12 V solar + battery. One unit ≈ one household; communities scale by the unit. → kalla.me #offgrid #offgridliving #smallholding #ecovillage #community #selfsufficiency #rainwaterharvesting #offgridwater #12v #madeinbritain **X:** One unit: 60–80 litres of drinking water a day. A household. One unit covers roughly 15–40 people's drinking and cooking water — communities just add units. kalla.me **Notes:** For the spec-minded. Good reply-card when someone asks "but how much water?" --- ## name — "Källa. Say SHELL-ah." **FB groups:** We named it Källa — Swedish for "source", said "SHELL-ah". Off-grid drinking water from the rain on your roof, made by hand in Britain. That's the whole idea. kalla.me **Instagram:** Källa. Say "SHELL-ah". Swedish for source. Off-grid drinking water, made in Britain. → kalla.me #kalla #offgrid #offgridliving #madeinbritain #rainwaterharvesting #selfsufficiency #design #branding #offgridwater #smallholding **X:** Källa. Say "SHELL-ah". Swedish for source. Off-grid drinking water from the rain on your roof, made in Britain. kalla.me **Notes:** Brand-recall micro-content. Use as profile/intro post, not a lead card. --- ## journey-1..4 — carousel: "Follow a raindrop, from roof to glass" **FB groups (album post):** Follow a raindrop from your roof to your glass — four stages, no chemicals, no cartridges, no mains. The living sand does the cleaning; the solar-powered UV-C reactor does the disinfecting. Full story at kalla.me. **Instagram (carousel caption):** Follow a raindrop → your roof, the living filter, the UV-C reactor, your glass. Four slides, the whole system. Swipe → and see the full journey at kalla.me #rainwaterharvesting #offgrid #offgridliving #selfsufficiency #permaculture #smallholding #ecovillage #biosandfilter #offgridwater #madeinbritain **X (thread starter, attach all 4 slides):** Follow a raindrop from a UK roof to a drinking glass — living sand, then a solar-powered UV-C reactor. A thread in 4 pictures. kalla.me **Notes:** Post order journey-1 → journey-4. Slide 4 carries its own CTA hand-note. --- ## Hook bank 1. Your roof already collects enough drinking water.
