Smart water for Tanzania
Water you can account for.
MajiLink connects the tanks you store water in to the households and taps it reaches, so the water you paid to supply is water your customers actually receive.
Three problems, one platform.

A reservoir fills past the top and spills for hours. Nobody knows until the water, and what it cost to pump, is already gone.
Know a tank is full before it starts spilling.
A solar sensor sits on the tank and watches the level for you. You close the supply at the right moment instead of finding out afterwards, and the same reading tells you when a tank is running low rather than over.
- Stop the supply before it overflows
- Water kept instead of spilled
- Check any tank from anywhere

People use water now and are billed weeks later, then argue the bill is too high. Nobody can prove otherwise.
Pay first, and there is no bill to argue about.
Your customers buy water before they use it, the same way they buy airtime, and they get exactly what they paid for. No reading taken at the door, no bill arriving weeks after the water, and nothing left for anyone to dispute.
- Buy water from a phone, at any hour
- Customers get exactly what they paid for
- No estimated bills, no overcharging claims

At a shared tap, water goes out all day and very little of it comes back as revenue.
One tap, many people, every drop paid for.
Each person buys water onto their own card before they draw it. The standpipe still serves the whole neighbourhood, and what it sells is recorded as it is bought, so a community supply stops being the one place the water quietly disappears.
- A card for every customer
- Water that is sold, not lost
- A shared tap you can account for
Most water is not lost to leaks.
It is lost to not knowing.
What was paid for
recorded as it is bought, not estimated later
Whether it arrived
and who is still owed water they bought
Which tank was spilling
and how long it ran over
MajiLink closes that gap, so you can account for every drop you supply.
Simple enough that nobody has to be trained.
1
Your customer pays
From their phone, at whatever hour suits them. No counter, no queue, no paper receipt to keep hold of.
2
The water reaches them
Their meter opens for what they bought. A card at a public tap works the same way.
3
You can see all of it
Every sale, every tank, every customer still waiting on something they paid for, all on one screen.
The things people ask us first.
If yours is not here, it is the kind of thing worth a conversation rather than a paragraph. Ask us directly.
Your customers need water they can rely on.
You need to know they are getting it. That is the whole of what MajiLink does. Tell us what your network looks like and we will tell you where to start.
