You turn on the faucet, water comes out. What you don\u2019t use runs down the drain and disappears. It feels simple, but every drop of water, whether coming in or going out, depends on a vast and complex system that keeps it safe for humans and the environment. \u00a0<\/p>\nRipples: Water, Community, and You is a special exhibit, now on display at the Johnson County Museum! It explores the history of our natural streamways and manmade water systems. Learn more at JCPRD.com\/Ripples.<\/em><\/figcaption><\/figure>\n
It might seem invisible, but hundreds of public servants and billions of dollars in infrastructure work every day to:<\/p>\n
\n
treat and transport water to your home,<\/li>\n
manage and dispose of your wastewater (sewage),<\/li>\n
direct stormwater away from neighborhoods, and<\/li>\n
preserve and restore natural streamways.<\/li>\n<\/ul>\n
Here are four key ways Johnson County manages water today!<\/p>\n
Water at Your Faucet<\/strong><\/p>\n
Today the water that reaches your tap has gone through an extensive, multi-step treatment process. Early Johnson Countians relied on creeks and wells for water to use and consume. Later, as suburban development began, some developers built small water systems. These were eventually purchased by the Kansas City Suburban Water Company in Mission, but residents grew frustrated as quality declined while bills increased.<\/p>\n
A citizen-led initiative created Water District No. 1 in 1957. This independent, nonprofit utility was founded to provide reliable drinking water to a growing suburban population. Today, 2,800 miles of pipe deliver water to about a half-million people spread out over 60% of the county. WaterOne\u2019s award-winning area treatment facilities are consistently recognized as producing the best tasting water in Kansas. <\/p>\nThis photo from 1961 shows the large pipes at WaterOne\u2019s Hansen Treatment Plant. Pipes like these, along with powerful pumps, provide water for consumption to much of Johnson County. Courtesy WaterOne.<\/em><\/figcaption><\/figure>\n
Elsewhere in Johnson County, rural water districts and municipal water plants treat drinking water. Gardner, Edgerton, and Spring Hill, for example, receive water from the Hillsdale Reservoir. Olathe manages and treats its own water supply. As of 2020, more than 700 county households still rely on private wells for their water.<\/p>\n
Water Down Your Drain<\/strong><\/p>\n
Until after WWI, most Johnson Countians used privies or outhouses for sewage. Such facilities could become unpleasant and needed to be periodically emptied.<\/p>\n
As suburban homes appeared, developers often installed individual septic systems. But crowding and poor conditions meant that one in three systems failed within three years in the immediate post-WWII era. <\/p>\nThe Tomahawk Wastewater Treatment Facility located in Leawood. Some of the steps of treatment are outlined in the diagram in the exhibition. Courtesy Johnson County Wastewater.<\/em><\/figcaption><\/figure>\n
In 1949, Johnson County opened its first wastewater treatment facility, the Nelson Treatment Complex in Mission, serving 15,000 people. Today six wastewater facilities handle sewage for 500,000 residents in 17 cities across the county. Wastewater goes through a multi-step process: solids are removed, dried, and disposed of or repurposed as fertilizer for livestock crops; liquids are clarified, treated, and returned safely to local streams and rivers. Every year, Johnson County Wastewater treats an average of 18 billion gallons of wastewater \u2013 that\u2019s approximately 50 million gallons each day!<\/p>\n
Not all household are on this system. Olathe treats two billion gallons annually through its own facilities. Septic systems, now much improved, are still common in the county: as of 2024, there were over 9,600 septic systems in use.<\/p>\n
Water in the Gutter<\/strong><\/p>\n
In 1990, Johnson County Public Works launched the Stormwater Management Program to help cities better handle rain and floodwaters from streets and parking lots. Their efforts built on decades of municipal management of stormwater. <\/p>\nThis diagram shows how Johnson County maintains two separate underground sewers \u2013 in yellow, the sanitary sewer or wastewater system; in red, the stormwater system. Wastewater is treated before reentering area streamways, while stormwater is not treated. Courtesy Johnson County Stormwater. <\/em><\/figcaption><\/figure>\n
Unlike sanitary sewers, stormwater in Johnson County is not treated before returning to rivers in creeks, so whatever runs off of pavement and yards and goes into roadside gutters and storm sewers is likely to turn up in nearby streamways. Despite potential for runoff and contamination of streamways, Johnson County\u2019s system meets the national standard for stormwater.<\/p>\n
County staff work with city stormwater officials in 20 cities, securing grants, maintaining floodplain maps, and improving infrastructure. To date, $200 million in improvements have been made through the Johnson County\u2019s Stormwater Management Program. Community programs like \u201cContain the Rain\u201d help prevent runoff by refunding the cost of rain barrels and native plantings at homes in participating cities.<\/p>\n
Water in the Streams<\/strong><\/p>\n
With over 1,800 miles of natural streamways, Johnson County is a well-watered landscape. Water flows here in many forms, ranging from small creeks to rivers. The county is also home to 13 small reservoirs and lakes, and numerous man-made ponds dot the landscape.<\/p>\n
Johnson County Park and Recreation District (JCPRD) has actively managed some floodplains in its parkland and conserved natural settings like wetlands, streamways, and lakes following its \u201cComprehensive Plan for the Development of Future Parks,\u201d released in 1979. Today JCPRD manages 400 acres of water and 1,300 streamway park acres along more than 70 miles of streamways. Parks staff coordinates with city park systems, conservation groups, nonprofit organizations, and volunteers to effectively manage water. <\/p>\nOne example of JCPRD\u2019s streamway stewardship is the recently completed Heritage Park lake dredging project. Over its 45 years, Heritage Lake had silted more than 40%, reducing its capacity and impacting its quality. Dredging increased its capacity to hold water, and the creation of a new wetland forebay will allow silt to drop out of creek water ahead of entering the lake, while also providing important habitat for wetland plants, animals, fish, and birds.

Most of Johnson County\u2019s creeks and streams originate in the county, putting JCPRD in a unique, upstream position to positively influence watershed restoration. JCPRD takes the role seriously and has received national recognition for its natural resources management.<\/p>\n
It\u2019s All Connected<\/strong><\/p>\n
Although we use water every single day, we rarely stop to think about where it comes from or where it goes. Drinking water, wastewater, stormwater, and streams may seem separate, but they are all interconnected parts of one system.<\/p>\nThis diagram is from an exhibit interactive element that helps children (and adults!) understand that our water systems \u2013 natural and man-made \u2013 are all connected. Visit the \u201cRipples\u201d exhibit to explore it yourself. Plan your visit at JCPRD.com\/Ripples!<\/em><\/figcaption><\/figure>\n
