Maintaining a robust water system that can withstand challenges and meet the future needs of a growing, dynamic metro area.

PLANNING

Strategically planning for new and expanded water treatment facilities while protecting source water for the next generation.

ABOUT

Central Iowa Water Works (CIWW) was formally founded on April 11, 2024, when 12 entities representing local communities, utilities and rural providers came together to establish the first-ever regional drinking water authority for the metro.

Collaboration among 12 founding entities.

Shared governance of water production.

Resiliency that assures future access and supply.

Local independence with regional water production.

CIWW Board

Unified voice in source water protection.

CIWW does not replace local water utilities, rural providers or city water departments. They remain the contacts for new accounts, bill-paying and customer service. Find your local provider here.
