Nnabu said that the exercise recorded 99 per cent compliance by the residents.
He said that the people showed that they appreciated the importance of keeping their environment clean.
He said: “The exercise was actually conceived to usher in the nation’s independence anniversary celebration in the state and it was successful.
“Leveraging the success, the ministry will consider the possibility of sustaining the monthly programme as it was in the past.
The commissioner attributed the success to the huge awareness created for the exercise through the media and other channels.
“Residents should also be commended for their compliance and identifying always with good policies.
“We urge them to sustain the trend,” he said.
He gave assurance that government would continue to implement policies that would enhance their well-being.
The News Agency of Nigeria reports that over 50 persons were arrested during the exercise by the ministry’s task force and security agencies.
The defaulters were tried by a Sanitation Court presided over by Mr Ifedi Nwangbo for violating various environmental offences.
The offences include loitering, travelling and engaging in recreational activities, amongst others, during the sanitation period.
They were sentenced to jail terms, ranging from one month to six months, with an option of fines between N5,000 and N50,000.
