Des Moines Water Works Fleur Drive Treatment Plant has the option of three different sources of raw water. The first and best source is a shallow groundwater collection system called the infiltration gallery. It is a three-mile long, porous pipe constructed with concrete rings. This runs parallel to the Raccoon River in Water Works Park, and collects water from the sands and gravels of the river valley. The ponds in the park are also there to help recharge the gallery. It provided all the water to the Des Moines area until 1949.
Increased water demand required construction of an intake on the Raccoon River in 1949, and the drought of 1977 precipitated construction of an intake on the Des Moines River in 1980.
Des Moines Water Works selects its source of water each day, and sometimes can change throughout the day, due to water quality and the ability to treat different substances present in the source water.
Some of the challenges Des Moines Water Works is faced with in selecting the best source water include:
- Availability: The first choice would be the gallery, but most days there is not enough capacity to supply all the water needed, so a second source is needed to supplement the gallery.
- Algae and bacteria: These can cause treatment challenges, such as plugging filters or taste and odor issues.
- Nutrients: Some of these are naturally-occurring in the environment, but most are man-made. They can be from sources such as agriculture, livestock, or wastewater treatment.
- Other: Turbidity (cloudiness of the water), hardness (dissolved minerals in the water), organic material (plant decomposition) or taste and odor.
- Episodic events: There may be an accidental spill or chemical release into the river.
- Cost: The gallery and Raccoon River are available at the Fleur Drive Treatment Plant, but the Des Moines River has to be pumped five miles from the intake to the plant. This adds additional cost when Des Moines Water Works must use the Des Moines River.
Many of the challenges Des Moines Water Works sees changes daily, so monitoring is done continuously. Evaluating the source water and determining what is the best available and at the cost is to treat that source ensure Des Moines Water Works can deliver water you can trust for life.
Forty years ago, in the midst of a national concern about untreated sewage, industrial and toxic discharges, destruction of wetlands, and contaminated runoff, the principal law to protect the nation’s waters was passed. The Clean Water Act (CWA) set a national goal “to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters,” with interim goals that all waters be fishable and swimmable.
The Act embodied a new federal-state partnership, where federal guidelines, objectives and limits were to be set under the authority of the U.S. Environmental Protection Agency, while states, territories and authorized tribes would largely administer and enforce the CWA programs, with federal technical and financial assistance. In Iowa, the Iowa Department of Natural Resources is delegated to administer the CWA.

Des Moines Water Work’s primary water sources are the Raccoon and Des Moines Rivers. Land use in the Raccoon and Des Moines River Watersheds is overwhelmingly agricultural. About 1.7 million of the 2.3 million acres in the Raccoon watershed is cultivated for corn and soybeans. Land covered by perennial vegetation is nearly non-existent outside urban areas. Much of the corn-soybean system requires constructed drainage (agricultural tile drainage) to maximize yields. Manure and commercial fertilizers applied to crop land are transported during rainfall events as either run-off or discharged to a river through a tile drainage system. All of these factors have resulted in various consequences for water quality and challenges for drinking water utilities.
Today, the Iowa Environmental Protection Commission (EPC) will meet to discuss whether or not to continue to ban manure application to soybean crops. Manure is a source of nutrients used in combination with or in place of commercial fertilizer. Nutrients in water are necessary for healthy watersheds; however, in high concentrations they can adversely affect aquatic life and human health. For a drinking water utility, increasing nutrient loads can cause difficult and costly challenges at the source, in the treatment process, and at the tap. Monitoring trends in the Des Moines and Raccoon River since 1974 show the ever-increasing trend of nitrate-nitrogen (a nutrient) loading and concentrations. Without a comprehensive, measurable state nutrient standard and strategy these conditions will be perpetuated.
All waters in Iowa are “public waters and public wealth” of its citizens and is for the beneficial use of all citizens. It is also the policy of the State of Iowa – delegated to the Iowa Environmental Protection Commission – to protect existing water uses and to protect and maintain the physical, biological and chemical integrity of all waters of the state. Making a decision on whether manure should be applied to soybeans is again representative of the piecemeal approach to nutrient management that will not effectively decrease non-point source nutrient contributions to Iowa’s surface and ground water resources.
Des Moines Water Works provided comments to EPC commissioners strongly urging them to take this opportunity to support development of comprehensive nutrient management strategies and standards. Standards that protect Iowa’s water resources, promote economic development, and enhance the quality of life necessary to attract workers and jobs to the state. And most importantly, establish the target so many producers and the public have requested.
It is not Des Moines Water Works’ intent to tell people how to farm or what they can and cannot do on their land. But it is our intent, to rigorously advocate for establishing a comprehensive nutrient strategy, setting numeric nutrient standards, and the aggressive reduction of non-point source nutrient contributions to Iowa’s surface and ground water resources.
Des Moines Water Works and the drinking water industry ensures that the investment the public has made in them results in all Iowans having access to safe drinking water. We believe every Iowan who drinks a glass of water should recognize the importance of our water resources to sustaining life and the critical connection between our water resources and food production, an existence and connection that should occur without degradation of our water resources.
Producers are able to make all the decisions on his or her land, but those decisions are having dramatic consequences that impact others. Integrated solutions on a watershed scale and involvement of all stakeholders in the planning and implementation process is critical to generating change. Whether you live in an urban, rural or something in-between, we are all part of the watershed and whatever we do in our daily lives impacts water quality in the watershed.Labels: Des Moines Water Works, Des Moines waterworks, DMWW, Raccoon River, Source Water, water quality, Watershed Posted in Environment, Source Water, Water Quality July 30, 2012
Des Moines Water Works through the Central Iowa Regional Drinking Water Commission Assisting Dallas County Board of Supervisors in Formation of a Middle-South Raccoon River Watershed Alliance
The State of Iowa has authorized local governments to address flooding and management of water and soil resources in watersheds across the state through the formation of local alliances. An alliance is formed through a 28E agreement (contractual agreement between governmental organizations) with representatives appointed by city, county and soil and watershed conservation districts (SWCD) within the watershed. An advisory body with landowners and other groups will also be part of the process. The watershed alliance has no taxing authority and no impact on the authority of a city, county, or SWCD to conduct its business. Instead, the alliance will educate, coordinate and leverage resources for the betterment of the watershed.
The Middle-South Raccoon River Watershed Alliance is working within the following vision and mission statements:
Vision: A regional alliance with resources to lead, and support improvements in soil protection, flood management and water quality.
Mission: To facilitate regional collaboration that will identify strategies and goals to educate the public, reduce the risk of flood events, and leverage resources for improved soil and water quality protection.
As outlined by legislators in Iowa Code the alliance can:
- Educate residents
- Identify sources of funding to institutionalize the Watershed Management Alliance
- Assess flood risks
- Assess options for cutting flood risk
- Monitor state & federal flood risk planning activities
- Assess water quality
- Leverage funding of multiple partners
- Allocate state and federal moneys available for water quality and flood risk reduction programs and implement best management practices
- Implement the Raccoon River Master Plan
- Enter into contracts and agreements

The Middle-South Raccoon River Watershed Management Alliance has just recently been selected to partner with the Iowa Flood Center (IFC) on a multi-year project to monitor, plan, and implement watershed projects aimed at improving soil and water resources and the adverse impacts of flooding. Phase I will focus on the Middle Raccoon River watershed. The IFC formally announced the partnership June 22, 2012, in Redfield, IA.
The landscape of the Middle-South Raccoon River Watershed is located in the best of rural Iowa, where community is tied to the tradition of farming and outdoor recreation. The benefits gained from the partnerships in the Middle-South Raccoon River watershed is a place where agriculture, communities, recreation, and Iowans thrive and prosper.Labels: Des Moines Water Works, Des Moines waterworks, DMWW, Raccoon River, Source Water, water quality, Watershed, Watershed alliance Posted in Environment, Flooding, Source Water, Water Quality June 4, 2012

The U.S. Department of Justice Drug Enforcement Administration (DEA) has scheduled another National Prescription Drug Take Back Day on Saturday, April 28, 2012, from 10:00 am – 2:00 pm. to provide a venue for persons who want to dispose of unwanted and unused prescription drugs.
National Prescription Drug Take Back Day addresses a vital public safety and public health issue. More than seven million Americans currently abuse prescription drugs, according to the 2009 Substance Abuse and Mental Health Services Administration’s National Survey on Drug Use and Health. Each day, approximately, 2,500 teens use prescription drugs to get high for the first time according to the Partnership for a Drug Free America. Studies show that a majority of abused prescription drugs are obtained from family and friends, including the home medicine cabinet.
Proper disposal of prescription drugs is also important to water quality. Unwanted prescription drugs thrown down the drain or toilet can end up in water ways, potentially harming aquatic life, recreational activities and the quality of source water used for your drinking water.

Some people are more sensitive to subtle changes in taste or odors. Des Moines Water Works (DMWW) uses the Raccoon and Des Moines Rivers as water sources. By using surface water, there can be some seasonal variations that occur. The treatment process should eliminate the variation in finished water, but sometimes there will be a slight change some customers may notice. For example, there may be a slight increase in smell or taste of chlorine at times, especially during a river’s spring thaw. This is easily remedied by storing water for drinking in a pitcher in the refrigerator.
If you think you have an issue with taste and odor of the water in your home, there are a few things you can do to determine the source of the problem. Check to see if the problem is apparent in all fixtures of the home. For example, is the issue apparent in the bathroom, kitchen and laundry room utility sink? Many times the issue is only at one fixture. This would indicate the cause is something in the household plumbing. A few things to consider would be: Has there been a recent change in the household plumbing? Do you have an in-home water treatment device that needs regular service or filter changes? Plastics can impart flavors and odors to the water; this can include parts in the faucet, plumbing lines, or appliances. If the problem is present in all fixtures, try running the tub or shower faucet for a period of time and then recheck to see if there is still an issue.
If it is an odor issue, try pouring a glass and then smelling it in another room. Sometimes the odor may be coming from another source, possibly a drain or garbage can, in the same room. By eliminating this possibility, one can ensure that it is the water that contains the odor. If you notice a sulfur odor, it may be from your home’s hot water heater. If the temperature is not set high enough, bacteria can grow in the water heater. A possible solution for this would be to turn the heater up high for a couple hours then return the setting to a normal level. If this is done, please use caution the first few times water is turned on, as water could still be hot.
If you are storing drinking water for convenient use, here are a few things to help prevent taste and odor issues. Store water in a glass container, as plastic can impart taste or odors to the water. Also make sure the container has a good seal. Store in the refrigerator as water will have less flavor when chilled. If the water has sat for a while, it may be flat. If this is the case, pour it back and forth between containers or shake it to help aerate the water. This will help to add oxygen to the water and remove the stale, flat flavor.
If you are still experiencing problems, please call your Des Moines Water Works at 283-8700 and report the issue and the duration the problem has been apparent. We will work with you to diagnose the problem.
Water Day at the Iowa State Capitol is January 17, 2012, and Des Moines Water Works will be there on behalf of the approximately 500,000 people in DMWW’s service area.
Every Year, DMWW sees Water Day as an opportunity to talk with legislators from Central Iowa and across the state about improving and protecting water resources in the Raccoon and Des Moines Rivers, the sources of water for DMWW drinking water. Reducing nutrients, bacteria, and algae blooms in our source waters helps protect public health and contain the cost of treating drinking water for our customers.
This is also an opportunity to discuss protecting the utility’s $352 million of infrastructure from flood events – infrastructure owned by the citizens of Des Moines. In 1993, the Fleur Drive Treatment Plant was flooded and DMWW was not able to provide drinking water to customers for approximately 10-14 days. Since 2008, more than 65-feet of river bank have been lost at the L.D. McMullen Treatment Plant well field site, putting several wells at risk for damage. More frequent (and intense) rainfall events and expeditious movement of water off the landscape through tiling, have exacerbated flooding. The connectivity of surface water, ground water and soils exist on all levels and need to be managed as a system. The power of moving water, whether a raindrop or a torrent of flood water, can be better managed in Iowa.Labels: Des Moines Water Works, Des Moines waterworks, DMWW, flood improvements, Flood of 93, Iowa Legislation, State of Iowa, water quality Posted in Customers, Environment, Flooding, Infrastructure, Public Policy, Water Quality January 11, 2012
Its stuffy nose season, and you may be in the habit of using a neti pot to clean your sinuses. However, we want you to be safe.
Recent news has reported two people in Louisiana who died after using a neti pot with amoeba-inhabited water.
Like Louisiana’s health authorities, Des Moines Water Works recommends neti pot users boil (then cool!) water before using it to irrigate your sinuses.
Naegleria is an amoeba that lives in natural water throughout the world. The Louisiana warning notes that Naegleria fowleri infections are very rare. In the 10 years from 2001 to 2010, 32 infections were reported in the U.S. However, people can contract it in Iowa as well as in other states. Tap water varies in its purity from one water utility to another. Finished drinking water provided by DMWW is nearly sterile, but there exists a miniscule chance that a Naegleria cyst could be present in some of the water. To be on the safe side, we recommend that you always bring water to a rolling boil and cool prior to using in your neti pot.
It is important to note that water for drinking or bathing presents no danger from Naegleria.Labels: Des Moines Water Works, Des Moines waterworks, DMWW, Neti Pot, water quality Posted in Customer Service, Health, Water Quality
