It has to be to cope with the bumpy and narrow lanes of the shanty town. The first big job of the day is to empty the multiple lavatory block at the local school. It's a messy business and the operators need protective clothing. Vacutug is designed to be made and operated locally in any country with sanitation problems like Kebira's. Atmospheric pressure forces the latrine contents along the hose-pipe into a 500 litre vacuum tank.
Drinking water is also at risk from contamination by human waste.
Kebira's water pipes run through its roads with minimal protection. They break easily and the water mingles with liquefied faeces from the overflowing lavatories. The job at the school finished, Vacutug empties its contents into the main sewer for hygienic disposal. The vacuum pump is reversible so the contents can be discharged quickly - up to 1,700 litres a minute. Vacutug is a business idea as well as a public health project.
