History and Establishment of Des Moines Water Works
Des Moines Water Works has a storied history that dates back over 150 years. Established in 1871, it began as a small, privately-owned water utility serving the growing Des Moines community. Over time, as the city expanded, the need for a more robust and publicly accountable water system became evident. In 1919, the utility transitioned to public ownership, adopting its current name, Des Moines Water Works, to reflect its commitment to serving the community.
The organization’s growth mirrored the rapid urbanization and industrialization of the region. Early infrastructure consisted of basic water pipes and pumps, but by the mid-20th century, DMWW had invested heavily in modernizing its facilities. This included adopting advanced water treatment technologies and expanding its service area to include surrounding suburbs and rural communities. Today, it stands as one of the most sophisticated water utilities in the United States, renowned for its innovation and commitment to quality.
Throughout its history, DMWW has faced numerous challenges, from natural disasters like floods to man-made issues such as pollution and agricultural runoff. However, its resilience and adaptability have ensured that it continues to meet the needs of its customers while safeguarding Iowa’s water resources.

How Does Des Moines Water Works Ensure Water Safety?
Ensuring the safety and quality of drinking water is at the core of Des Moines Water Works’ mission. The utility employs a comprehensive approach that combines rigorous testing, advanced treatment methods, and proactive source water protection to deliver water that meets or exceeds all regulatory standards.
Rigorous Water Testing
DMWW conducts thousands of water quality tests each year, analyzing for a wide range of contaminants, including bacteria, viruses, heavy metals, and agricultural chemicals. These tests are performed at multiple stages of the water treatment process, from source water to treated water ready for distribution. The utility’s state-of-the-art laboratory is staffed by highly trained scientists and technicians who ensure that every drop of water is safe for consumption.
Advanced Treatment Methods
The water treatment process at DMWW involves multiple stages, including coagulation, sedimentation, filtration, and disinfection. In recent years, the utility has also invested in advanced technologies like granular activated carbon (GAC) filters and reverse osmosis systems to address emerging contaminants such as nitrates and pharmaceuticals.
Source Water Protection
Recognizing that the best way to ensure water safety is to protect it at its source, DMWW collaborates with local farmers, government agencies, and environmental organizations to reduce pollution in the rivers and aquifers that supply its water. Initiatives include promoting sustainable agricultural practices, restoring wetlands, and implementing buffer zones along waterways.
Water Treatment Process: From Source to Tap
The journey of water from its source to your tap is a complex and meticulously managed process. Des Moines Water Works sources its water primarily from the Raccoon and Des Moines Rivers, as well as underground aquifers. Each source presents unique challenges and requires tailored treatment methods to ensure safety and quality.
Stage 1: Source Water Collection
Water is drawn from the Raccoon and Des Moines Rivers through intake structures designed to minimize the entry of debris and sediment. Groundwater is also extracted from deep wells, providing an additional water source during periods of drought or high demand.
Stage 2: Coagulation and Sedimentation
Once collected, the water enters the treatment plant, where coagulants are added to bind small particles together into larger clumps. These clumps, or flocs, settle at the bottom of sedimentation basins, removing a significant amount of turbidity and particulate matter.
Stage 3: Filtration
The water is then passed through a series of filters, typically made of sand, gravel, and activated carbon. These filters remove any remaining particles, as well as contaminants like organic compounds and microorganisms.
Stage 4: Disinfection
To eliminate any remaining pathogens, the water is disinfected using chlorine or other approved methods. This step ensures that the water is safe to drink and free of harmful bacteria and viruses.
Stage 5: Distribution
Finally, the treated water is pumped into the distribution system, which includes a network of pipes, storage tanks, and pumping stations. From here, it is delivered to homes, businesses, and other facilities across the Des Moines metropolitan area.
What Are the Main Water Sources in Des Moines?
Des Moines Water Works relies on three primary water sources: the Raccoon River, the Des Moines River, and underground aquifers. Each source plays a critical role in meeting the city’s water needs, and DMWW employs comprehensive management strategies to ensure their sustainability.
The Raccoon River
The Raccoon River is the primary surface water source for DMWW. It flows through a predominantly agricultural region, making it susceptible to pollution from fertilizers, pesticides, and animal waste. Despite these challenges, the river remains a vital resource due to its proximity and capacity.
The Des Moines River
The Des Moines River serves as a secondary surface water source. It provides additional water during periods of high demand or when water quality in the Raccoon River is compromised. Like the Raccoon River, it faces challenges related to agricultural runoff and urban pollution.
Underground Aquifers
In addition to surface water, DMWW taps into deep underground aquifers, which offer a reliable and high-quality water source. These aquifers are particularly valuable during droughts or other emergencies when surface water supplies are limited.
