Pit Latrine Sensor

Know when every latrine needs emptying

Cost effective monitoring of latrine fill levels, with automated collection notifications.

The MAT pit latrine fill-level sensor

The problem

Latrines fill up unseen

A pit latrine gives no warning before it is full. Poorly managed pits can contaminate groundwater and open drains, spreading disease.1

Our fill level sensors collect vital data on the fill levels of school and institutional latrines. That data enables timely waste collection, benefiting both schools and waste management companies.

Collection process

How it works

From a full latrine to fertiliser, with every step triggered by data.

  1. 1

    Measure

    Sensors continuously measure and send the fill levels of the latrines.

  2. 2

    Schedule

    The platform receives fill levels and automatically schedules collection when a latrine is 90% full.

  3. 3

    Notify

    Details are sent to available pit emptying groups and exhauster trucks.

  4. 4

    Collect

    Waste is safely collected and transported for processing.

  5. 5

    Recycle

    Recycling plants convert the waste to bio char and fertiliser for sale.

Alerts

A text message when it's time

The sensor sends SMS alerts when a pit latrine reaches a set level and needs emptying, so nobody has to check it by hand.

Pit owners can also see the details of their latrines, including fill level and temperature, on our platform.

SMS alerts on a phone: "Waste Tank at A-12 is Full", then "Cleared"
Real alerts: a tank reported full, then cleared after collection.

The platform

Every latrine on one dashboard

All sensors are monitored on our web-based dashboard, so latrines can be checked from anywhere with an Internet connection.

Our sensor data also optimises collection routes, so trucks and emptying groups go where they're needed.
