Definition of County.

A landfill is basically a big hole into which household garbage is dumped. When filled, the area will usually be covered by a layer of earth and grassed, to hide the ugliness of what lies beneath.

little distorted from country

A country can be made up of many counties.

but is not it looks odd
'If the county continues to collect residential trash"

county collects residential trash !

is it correct usage ?

A county is usually a smaller part of a country, subject to the national laws of that country, but with a local "government" that takes care of the local administration along the guidelines of the nation's laws and directives.

Yes, it is correct usage.

The word "County", in the statement 'If the county continues to collect residential trash", is a quick and easy way of identifying who is actually responsible for carrying out that duty.
I know that, specifically, it is the men who come and collect the trash who are physically completing the task, but they are either appointed or employed by officials in the County, and are completing that task on behalf of the County.

A more specific, but complicated way of making the same statement would be "If the men who are appointed or employed by the County to take and dispose of trash on behalf of the County, continued to collect residential trash..."

Other similar "simplified" statements would read :
"The County are coming to fix the road next week"
or
"The County ought to put up more street lights in town"

Where are you from, tintin?

If you can translate it into English, how would you say it?

Just curious.
