Clearwell
A gravity-fed, solar-assisted water station that turns any village well, river or rain tank into safe drinking water for 2,000 people a day. No grid. No chemicals. No specialist to maintain it.
Two billion people still drink water that can make them sick.
without safe water at home
Families walk an average of 6 km a day to collect water that is often contaminated.
children lost every day
Diarrhoeal disease from unsafe water remains a leading killer of children under five.
of rural filters fail in year one
Imported systems break, need spare parts nobody stocks, or depend on power that isn't there.
Figures are illustrative for this concept deck.
A water station built to outlive its warranty.
Clearwell is a modular, 1.8 m tall station assembled on site from six parts in under two hours. Gravity does most of the work; a 40 W solar panel powers the UV-C stage and a small sensor board that reports water quality over SMS.
Four stages, zero chemicals, one tap.
Settle
A 200 L header tank lets sand and silt drop out before water reaches the filters.
Filter
Silver-lined ceramic candles at 0.2 microns stop bacteria and protozoa. Activated carbon handles taste and some chemicals.
Sterilise
Solar-powered UV-C LEDs neutralise any viruses that remain, at under 8 W of power.
Report
Turbidity and flow sensors text the operator weekly and flag when a candle needs a 10-minute scrub.
Designed with the people who maintain it.
Every Clearwell station comes with a trained local caretaker, a laminated picture manual in the local language, and a spare-parts kit that fits in a backpack.

design life of the ceramic core
Tested in 3 regions, 41 stations, 18 months.
Nyamira Basin
17 stations serving 31,000 people from turbid river water. Clinic visits for diarrhoea fell 58% in the first year.
92% uptime
Kalema Hills
14 stations on hand-dug wells. Caretakers made every repair themselves; median fix time was 22 minutes.
97% uptime
Sabani Delta
10 stations on rain tanks, plus a desalination add-on in beta. Girls' school attendance rose 21%.

What 41 stations did in 18 months.
people with daily safe water
litres filtered and logged
waterborne illness at partner clinics
CO₂ avoided by not boiling water
Water as a service, priced below what families pay to boil it.
Community tap
Families pay 5 cents for 20 litres by mobile money. That covers the caretaker's wage and spare parts, and leaves a 22% margin.
Institutions
Schools and clinics sign 5-year service contracts, often co-funded by NGOs and county health budgets.
Carbon credits
Verified emissions avoided from boiling bring in about $180 per station each year, paying back the hardware in 7 years.
