Chilling in Water Works Park

RAGBRAI riders love our water stationsApproximately 10,000-12,000 RAGBRAI riders and their support teams camped overnight in Water Works Park July 23, 2013.  One cyclist was overheard remarking that Water Works Park was “by far the coolest camp” he’d experienced in his 16 years of riding.

While riders and campers enjoyed the nature of the park and the close community it provided, the “hot” commodity was a chilled water station where bicyclists could fill  their reusable water bottles with ice cold tap water.  Recently designed by Des Moines Water Works staff, the water station connects to any water supply and utilizes ice to cool the tap water flowing through a 100’ coil to four bottle filling faucets. Chilled water was extremely popular as the riders are accustomed to drinking lukewarm tap water all day long.

Two additional water stations were strategically positioned in the campground to provide thousands of gallons of water for the campers’ needs.  Riders were extremely appreciative of the plentiful supply of water allowing them to clean up and board a bus to experience the festivities in downtown Des Moines.

Cyclists and their support teams got an early start July 24 and by mid-morning, few traces remained of the epic camp-out the night before.  From all accounts, cyclists enjoyed their stay in Des Moines and the hospitality offered by the entire community.  In return, DMWW thanks RAGBRAI-ers for being great stewards of Water Works Park.  Come back and enjoy!

2013 Consumer Confidence Report

DSC_1980

Des Moines Water Work is committed to delivering safe, affordable and abundant drinking water to our customers. Safe drinking water is treated water that has been tested for harmful and potentially harmful substances and has met or exceeded drinking water quality standards set by the United States Environmental Protection Agency (EPA) and the State of Iowa. The EPA sets drinking water standards to define the limits of contaminants considered safe for drinking water. These levels are based on studies of the health effects associated with each contaminant and include a sufficient safety margin to ensure that water meeting these standards is safe for nearly everyone to drink.

The Consumer Confidence Report is an annual water quality report that helps customers understand the quality and safety of tap water provided by Des Moines Water Works. The current Consumer Confidence Report is now available on Des Moines Water Works’ website at http://www.dmww.com/upl/documents/library/ccr2013.pdf.

If you would like a printed copy of the Consumer Confidence Report mailed to you, please contact a Customer Service Representative at (515) 283-8700. If you have any questions about your drinking water, please contact Des Moines Water Works at (515) 283-8700.

Managed Irrigation Requested, Even as Drought Conditions throughout Central Iowa Improve

Des Moines Water Works is asking metro area customers – residential and commercial – to manage seasonal irrigation for the next several weeks, even as drought conditions throughout the state continue to improve.

Due to the recent historic nitrate concentrations found in the Raccoon and Des Moines Rivers, Des Moines Water Works is not currently pulling water from either river.  The utility is able to meet current demand by relying on other water sources, including Maffitt Reservoir, Crystal lake and aquifer storage wells.  If demand increases, Des Moines Water Works will have no choice but to start taking water from the heavily polluted rivers, and may be unable to remove nitrate in a manner that keeps up with high demand.

“Although drought conditions are no longer an immediate threat to Central Iowa, increased nitrate levels from agricultural run-off, coupled with high demand, puts Des Moines Water Works in a difficult position,” Bill Stowe, CEO and General Manager, Des Moines Water Works. “With the assistance of all metro customers using water wisely, Des Moines Water Works can effectively and efficiently use the available water supply to provide safe drinking water that does not violate nitrate standards.”

Wise use of water is defined as identifying efficient lawn irrigation practices, taking advantage of technological advances to eliminate waste, as well as being alert to and repairing leaking household fixtures or other large water consumption appliances in homes and businesses.

Wise water best practices for residential and commercial irrigation use include:

  • Avoid lawn watering, whether from an in-ground sprinkler system or manual sprinkler, during the day time hours of 10:00 a.m. and 5:00 p.m.  Evaporation from the sun is highest during this time period and less water is absorbed into the soil, meaning more water must be used to get the same effect than if watering is done outside these hours.
  • Shift watering to no more frequently than the ODD numbered days of the week if your house address ends with an ODD number and EVEN numbered days if your house address ends with an EVEN number.  For example, if your house number is “1521,” it is suggested that you water on the 1st, 3rd, 5th, 7th, and so on days of the month.
  • Test the irrigation system each spring to ensure there are no leaking sprinkler heads and that each head is properly directing its spray onto the turf and landscape.

Customers Pay When Others Pollute

In response to Iowa Farm Bureau Federation’s environmental policy adviser, Rick Robinson’s “State Rules Wouldn’t Fix Nitrates” letter to The Des Moines Register on May 13.

Nitrate Removal FacilityThanks to a capital investment made years ago and the dedicated work of our employees Des Moines Water Works continues to meet the needs of the 500,000 customers in the twenty communities we serve. However, the extreme levels of nitrates found in our water supply this year poses a significant threat to our customers. We feel it is time for Iowans to engage in a serious discussion about this growing problem.

Nitrate levels in both the Raccoon and Des Moines Rivers exceeded the U.S. Environmental Protection Agency (EPA) nitrate standard (10 mg/l – determined as the level protective of public health) this spring. There were more nitrates in those rivers last week than there were all of last year combined.

Des Moines Water Works relies primarily on the Raccoon and Des Moines Rivers as sources for Central Iowa’s drinking water. Because unprecedented nitrate levels have affected both rivers concurrently, Des Moines Water Works activated its Nitrate Removal Facility last Friday to keep finished drinking water below EPA standards. This facility, constructed in 1992 for $3.6 million, costs $7,000 per day to operate. Ratepayers fund the cost of constructing, maintaining and operating this facility.

We agree with one thing Rick Robinson of Iowa Farm Bureau Federation wrote, “if we all do our part – farmers, homeowners, businesses and communities – we will have a positive impact on Iowa’s watershed.” Where we diverge is that we do not believe everyone is doing their part to protect Iowa’s waterways.

Des Moines Water Works had the foresight to build a denitrification facility. DMWW has not had to operate it since 2007, but this is largely because DMWW has invested millions of additional dollars in additional treatment options to provide denitrification since 2007. It is misleading for a person to suggest the denitrification facility’s lack of use during recent years is proof nitrate levels have been lower than they have been in past years. DMWW has been able to avoid the costly operation of the facility because of other actions and investments it has made.

The heart of Des Moines Water Works’ mission is protecting public health. We can no longer work quietly while source waters continue to be severely polluted by upstream land practices. This should not be a sterile discussion influenced only by data and statistics—although ample alarming data and statistics exist. Nitrates pose serious health risks. It is increasingly costly for Des Moines Water Works to remove nitrates through treatment processes to meet necessary EPA standards.

There is simply no disputing surface water is significantly impacted by certain types of land use – the primary land uses in our upstream watersheds are agricultural related. Chemical fertilizers applied to fields are exacerbated by field drainage tiles, allowing run off to reach rivers and streams quickly and without the benefit of natural filtration and, this year, plant uptake.

In addition to exceptional levels of nitrates, high levels of ammonia and phosphorus, algae blooms, and increasing levels of bacteria are all deteriorating water quality in Iowa. The recently published Nutrient Reduction Strategy supported by many prominent State leaders, including Iowa Department of Agriculture and Land StewardshipIowa Department of Natural Resources, and the Governor’s office, is inadequate in that it lacks regulation, goals, measurable outcomes, or timelines for reducing agricultural (non-point) discharges. We advocate regulation through EPA-endorsed numeric standards by watershed—an approach with local emphasis that considers the current state of each watershed and does not force a one-size-fits-all approach.

Facing the reality of the degrading water quality and open meaningful discussion to identify solutions is long overdue.

Iowans should demand state leaders address improving and protecting owa’s water sources. State funding to support monitoring of nitrate pollutants should not be stripped away from the flood center of Iowa, an objective guardian if Iowa’s rivers and streams. Without significant action, Des Moines Water Works will be forced to continue treating degraded source waters, and our customers will continue to pay for that extensive treatment in their rates. With bold and innovative action, Des Moines Water Works believes healthy source waters and agriculture can co-exist. They must—both are critical to Iowa’s future.

Respectfully Submitted,

Graham Gillette, Chair

Bicycle Fundraising Event for Clean Water

WaterRideOn May 11, The Move Project will host The Water Ride, a bicycle ride that raises funds for clean water projects in Africa. Starting and ending at Mullets, riders have the option to ride 20, 40 or 85 miles.

The Move Project is a non-profit organization that focuses on the alleviation of poverty, freeing slaves, providing shelter to the homeless and food and water to those without access to these life essentials.  Des Moines Water Works is The Water Ride’s sponsor this year, covering all costs associated with the ride.

“This event is powerful in that 100% of the funds raised on this ride will go directly to providing clean water to a community in Africa. Having access to clean water affords individuals and families the opportunity to receive an education, work and live a healthier life,” said Sam Mahlstadt, co-founder of The Move Project.

“The Water Ride elevates our community’s awareness of the inaccessibility of water in other countries, as well as celebrates our local drinking water quality,” said Bill Stowe, CEO and General Manager, Des Moines Water Works. “The Water Ride is a great way to culminate our National Drinking Water Week festivities and emphasize the value of drinking water to a community’s overall health.”

Sign up by going to www.thewaterride.eventbrite.com by May 3, to receive a t-shirt at the event.

“When I took a summer off last year to ride my bicycle across America for clean water projects in Kenya, I realized how easy it is to tie in a passion to benefit others. If riding a bike for half a day could transform a community, there’s no question about signing up,” said Emily Boyd, co-founder of The Water Ride.

Water’s Role in Public Health

Des Moines Water Works celebrates public health during National Public Health Week (April 1-7, 2013), a time to recognize the contributions of public health and highlight issues that are important to improving our nation. In a world where an estimated 3 million people die every year from preventable waterborne disease, our water systems allow us to drink from virtually any public tap with a high assurance of safety. Each community water supply meets rigorous federal and state health protective standards.

Drinking water quality has a major influence on public health. Improvements in drinking water quality have dramatically improved the public’s health in the United States. However, some old challenges remain and new ones are emerging. Access to plentiful healthy source waters treated for drinking water are becoming limited by the increased presence of contaminants, new and more stringent regulations, and aging infrastructure. The public costs to safeguard our drinking water supply will be high without changes in land use that prevents the continued increase of contaminants from reaching our water sources, but the costs associated with failing to do so are likely to be much higher.

Des Moines Water Works (DMWW) is committed to protecting public health by assessing water quality in the Raccoon and Des Moines River watersheds and mitigating the public’s exposure to contaminantsthrough treatment.We work with landowners to help identify appropriate barriers for controlling contaminants that do not focus on expensive treatment processes, but rather consider a range of options that may result in improved water quality and in our ability to ensure quality drinking water after treatment. This is a holistic approach of managing water resources from our source to your tap.

For 40 years, the Safe Drinking Water Act (SDWA) has been the regulation by which drinking water utilities adhere to, to protect public health. When the SDWA became law in 1974 it required the Environmental Protection Agency (EPA) to set enforceable standards for health-related drinking water contaminants. The SDWA has been reauthorized in 1986 and 1996. In fact, the drinking water industry is one of the most regulated industries in the United States. In addition to meeting EPA drinking water standards, DMWW is proactively monitoring emerging contaminants that may require regulations in the future.

Protecting public health is the reason that the drinking water industry exists. The public health effects of current and future contaminants is the motivation behind the need for sustainable infrastructure, skilled operators, technical expertise, leadership and improvement and protection of the Raccoon and Des Moines River watersheds.

Where Does Your Water Come From?

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.

40th Anniversary of the Clean Water Act

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.

The Act also gave citizens a strong role to play in protecting and restoring waters. Ways you can support and become involved in improving and protecting water quality in your watershed:

  • Start or join a watershed improvement and protection group
  • Organize a river, stream or lake clean-up event
  • Get trained as an IOWATER volunteer
  • Get school kids, churches, civic organizations involved in education, projects and programs
  • Talk with policymakers about your support for watershed funding and programs – City Councils, County Supervisors, Legislators and others
  • Write letters to the editor of  your local newspaper about what good water quality means to you
  • Talk with family and friends about the importance of clean water

We must work together to protect clean water in Iowa for our families and future generations. Everyone has an impact on the water and we are all responsible for making a difference. Water is worth it.

Manure Application to Soybeans

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.
