So how do we keep it clean? There are a lot of ways to do that but first in is to start from each house. Since it is agreed that one house or one man can't clean the whole town thus it is the responsibility of each of the occupants.
A collective responsibility therefore means that dustbins should be placed in front of each house where passers by can throw in their litter and the occupants them selves can throw their daily garbage which should be collected by the unions garbage trucks every day.
Second measure that can be taken is to impose laws and penalties for those who don't follow it. The reason for such action is necessary so that people who take cleanliness for granted should be reminded that their dirtiness can have harmful effects on themselves plus on the people living around them.
Another way to get your town clean can be by starting society service which should become mandatory for the school students as part of their extra curricula activities. By this you can start the awareness of being clean in the kids plus you get your town clean.
Awareness is necessary as most of us are unaware of the harmful effects that dirty places cause.
All in all, there can be many ways to keep a town clean. As far as there is a will, there is always a way.
