Ndambuki, who operates a bar and a public toilet, revealed that he was forced into the genius invention by the challenges he faced as he administered his business.
“I used to have padlocks at the toilets, but when customers come, some of them are not straight forward and I ended up replacing numerous keys and padlocks, on a weekly, even monthly basis,” Ndambuki stated.
“I could not take it anymore so I decided to make the door,” he added.
The door which took Ndambuki one and a half years to make is made of metal and has a slot for the insertion of a token which a customer is given upon payment of Ksh 10 at the reception.
When the token is inserted, the door opens and displays a notice informing anyone in line that the lavatory is in use.
According to Ndambuki, the technology he employed has numerous advantages for the public good.
“It is hygienic, it reduces the spread of diseases, secondly, it can be used on a wide scale, even the public toilets in Nairobi could utilise these doors,” Ndambuki affirmed.
“Thirdly, for public use, this door allows the operator of a public toilet to easily keep account of all the people who accessed the facility at the end of the day,” he added.
Since the invention operates mechanically, it could easily be used in areas with no access to electricity.
Ndambuki’s invention welcomed recognition by Makueni Governor Kivutha Kibwana who acknowledged his efforts.
