Drainage Districts

Drainage Taxes:
  • Drainage Bills will be mailed on Friday, May 3rd, 2019.
  • Drainage Taxes are due on June 5th and September 5th, 2019.

Drainage Districts may be formed to construct, maintain, or repair drains or levees or to engage in other drainage or levee work for agricultural, sanitary or mining purposes.


The County Collector will be the treasurer of a drainage district if the district so desires. Your collector bond will cover this duty. You will be reimbursed the actual costs of providing such a service by the drainage district.

The drainage treasurer will bill and collect the drainage taxes. The drainage district will pay for this service. The commissioners of the drainage district will review the books once per year.

Drainage taxes are due June 5th and September 5th, 2019. Delinquent taxes are charged 1.5% per month. Any drainage taxes not paid by September 5th, 2019, shall be turned over to the collector and treated as delinquent taxes.

Commissioners are paid out of the drainage funds by a court order from the circuit judge.

Drainage districts can roll over yearly assessments in order to pay for a large project or cover emergencies. Funds may be transferred to general corporate funds only by court order.
