Police said the rains left a trail of destruction, displacing over 40 families amid the search.
Among the dead were three minors and four women following the incident that was caused by flash floods from the nearby Eburru hills, police said.
The incident occurred at around 8 pm as families were preparing to sleep when the gushing waters swept away their homes killing the seven and burying others in the mud.
Gilgil OCPD Francis Tumbo said the bodies of the four women and three minors had been collected and taken to Gilgil mortuary.
“Due to the heavy rains on Monday there was little that we could do and the search and rescue operation had to wait until in the morning,” he said.
Tumbo said some of the affected areas were still inaccessible as roads had been cut off by the flash floods.
“Unknown numbers are missing and we are working with area residents in the search and rescue operations,” he said.
Eliud Muriuki, a survivor said the area had received minimal rainfall though it had rained heavily in the hills.
He said that they were woken by screams as the water swept tens of houses and properties in the area.
Gilgil MP Martha Wangari said seven bodies had already been recovered as the search for the others kicked off.
Wangari added that her office was working closely with other government agencies to assist those left homeless by the floods.
“We woke up to sad news as we have lost seven people following heavy rains in Oljorai and scores of people have been left homeless,” she said.
