Metropolitan Water Reclamation District of Greater Chicago

Annual Budget

Every year, the MWRD creates and shares a full financial plan for the budget year. The budget year starts on January 1 and ends on December 31. Following the laws of Illinois, the MWRD maintains a balanced budget and regularly keeps track of the money coming in and going out. It has a long history of responsible financial management and is committed to providing taxpayer value to the residents of Cook County. 

Guided by the Strategic Plan, elements of the plan are incorporated throughout the budget document. The $1.4 billion budget invests in public infrastructure, tackles flooding issues, and continues a commitment to fully funding the Retirement Fund. It also receives federal funding to address flooding and optimizes critical asset life cycles through the Capital Improvement Program.


The Metropolitan Water Reclamation District provides stormwater management and water treatment to the communities served.

Here are some of the areas where the budget is applied during the fiscal year:
