Nakuru Public Health officer Samuel Kingori has urged land lords to construct toilets and latrines to combat diseases like cholera.
Mr Kingori also urged the landlords to construct bathrooms to avoid congestion that can lead to spreading of diseases in the slums.
"I want to urge all landlords and landladies to construct toilets and bathrooms for residents to avoid spreading of diseases especially this season of heavy rains,"said King'ori.
The officer was speaking in Nakuru on Wednesday claiming that he has received many reports that there were no latrines and bathrooms in many of the slum areas in Nakuru the fact that has led to many diseases in the informal settlement.
He warned that any plot that will be found without latrines it will be closed and action taken against the owner.
Mr King'ori said it was against the law to find more than twenty people using the same bathroom.
"How can more than twenty people use one bathroom? That cannot happen."
