Colchester is asking the U.S. Environmental Protection Agency for up to eight years to complete a large-scale sewer project.
The city has two options to pay for the $4.2 million project.
If the city qualifies for loans and grants through the U.S. Department of Agriculture's Rural Development program, the project might be completed in four years.
If the project qualifies for grants through the EPA the project might take eight years. That's because the city could only apply every other year.
