A: No. You can decide if and when you would like to connect.
A: Low pressure sewers are sewer systems where each individual home has its own grinder pump unit which pumps into a pressurized system, which in turn, flows into a nearby conventional gravity sewer system.
A: Gravity sewers are not suitable for most lake communities. Low pressure sewers were designed to be used in lake communities.
A: This is very unlikely as there are two check valves in the system between the main and the house to prevent this from happening.
A: No. Current state statutes do not allow Gardner Lake residents a right to vote on future annexation proposals by the City of Gardner and the sewer creation documents cannot require it.
A: No. The GPU is very quiet and can’t be heard unless you stand directly over it. Even then, it is very quiet.
A: The four inch service line that goes from the home to the grinder pump unit is the responsibility of the homeowner. The pump, control panel, discharge line, and main line are all maintained by Johnson County Wastewater.
A: No. There is no separate charge for this service. Johnson County Wastewater pays for normal maintenance and replacement of the grinder pumps. Funds for this are collected with the bi-monthly user charges paid by all Johnson County Wastewater customers.
A: This is a very reliable technology that has been used widely for over 30 years. Johnson County Wastewater has around 350 pumps in use today, dating back to 1998. Based on this experience, on average, a home with a grinder pump will have a maintenance call once every five years. Johnson County Wastewater's maintenance provider typically responds within two hours on every call and will restore service very quickly once they arrive.
A: Every control panel displays the 24 hour service phone number of our maintenance provider. Currently, every year Johnson County Wastewater sends out a letter and refrigerator magnet with the maintenance number listed.
A: There is a button on the bottom of each control panel. Once you push it, the audible alarm will stop. However, the visual alarm will stay lit.
A: First, you need to reduce water use as much as possible because there is limited storage in the pump unit, and if that storage is exceeded, the sewage will back up into your house. If the power is out for more than four hours, please call the 24 hour service phone number and a technician will be sent to hook a generator to your pump to pump it down. The technician can pump down the system twice a day, but due to limited storage in the pump unit, they are only pumping out about 30 gallons at a time. So, you should reduce water use as much as possible.
A: According to the manufacturer, it takes the same amount of electricity to run a 40 watt light bulb 24 hours a day, or about $28 per year.
A: 240 volts, and 20-30 amps. It may be necessary, at the homeowner’s expense, to upgrade to a 100 amp service if the existing service is less than 100 amp.
A: Yes. Under the construction contract, the contractor must repair the roads, where they are damaged by the construction work, back to their original state.
A: Generally, the mains are installed parallel to streets in street right-of-way, but not in the streets, except at locations where the main crosses the street.
A: Yes. If there is a major problem with your septic system or holding tank, you will be required to hook to the existing sewer system at that time in accordance with the Johnson County Environmental Code under the jurisdiction of the Johnson County Health and Environment Department.
A: Yes. If you decide to connect to the sewer system once the main lines are in, you will be required to reroute all wastewater to the grinder pump unit at that time.
A: Yes. Under county code requirements, every time a house changes ownership in the unincorporated area of Johnson County, the septic system must be inspected by the Johnson County Health and Environment Department.
A: If it is a minor problem, like a missing baffle or tee in the tank, it can be fixed without major expense. However, if there is sewage surfacing or a cracked tank, then a holding tank will be required if the property is within 200 feet of the lake. Also, if a sewer is available, the property owner will have to connect at that time.
A: Prior to the initiation of construction, if it is determined the project cost exceeds the budget cost by more than 10 percent, all property owners in the district will be notified of a public hearing to reconsider the project. After the hearing, the Board of County Commissioners will determine whether to complete the project. If the Board does not authorize completion of the project, any costs for engineering, right-of-way acquisition, etc. incurred, will be assessed to the properties in the district. If the Board authorizes completion of the project, property owners will be assessed the higher costs.
A: Currently, these pumps cost around $3,500 each. The total amount of an installed unit is approximately $7,500 to $8,500. This is a cost financed by the homeowner, not Johnson County Wastewater.
A: Every assessed lot would pay an estimated lump sum amount of $2,148. You can also choose to have this cost put on your tax bill over a 20-year period at an estimated 2.75 percent interest rate. The resulting estimated amount would be $141 per year for 20 years. If the final cost of the project is more or less than these estimates, you will be assessed the actual costs.
In May 2009, federal, state, and local officials broke ground on the largest "green infrastructure" project in the State of Kansas to be funded by the American Recovery and Reinvestment Act (ARRA) of 2009 -- nearly $18 million in a series of improvements to Johnson County's Douglas L. Smith Middle Basin Treatment Plant (DLSMB).
The facility is located in Overland Park, bordered by commercial and residential development. Originally constructed in 1979, it was recently expanded from 12 million gallons per day (MGD) to 14.5 MGD and upgraded to meet strict nitrogen and phosphorus effluent goals. As a result of that expanded liquid treatment capacity, additional solids processing capabilities were needed. Thus plans were developed to expand the anaerobic solids treatment system.
This project was “shovel ready,” which was a requirement for funding when the ARRA was approved in 2009. Through the Environmental Protection Agency's State Revolving Fund program, administered by the Kansas Department of Health and Environment, this project was awarded $17.8 million as a “green” project with $8.1 million of this amount as principal forgiveness or in other words, a grant.
The co-generation facility at the Douglas L. Smith Middle Basin Wastewater Treatment Plant produced 7,014,000 kWh of green power (power produced off the grid) in 2013.
The project was originally borne of the desire to increase solids handling capacity while reducing the carbon footprint. In December 2007, the Johnson County Board of Commissioners passed a resolution to reduce greenhouse gas emissions by one third by 2020, County-wide by 80 percent by 2050, and to reduce GHG from energy use in new and largely renovated County buildings to zero by 2030. The project, built by contractor BRB Contractors, Inc. of Topeka, Kan., was officially approved by the Johnson County Board of Commissioners in March 2009.
Components of the treatment plant improvements included the construction of a new anaerobic digester, a FOG (Fats, Oils and Grease) station to more efficiently receive and treat used greases and oils from restaurants and industries, and a cogeneration system to produce virtually all of the plant's annual operating energy from captured biogases.
President Obama signed the American Recovery and Reinvestment Act of 2009 on Feb.17, 2009, and directed that the ARRA be implemented with unprecedented transparency and accountability. To that end, the American people can see how every dollar is being invested at www.recovery.gov. The Recovery Act seeks in part to spur technological advances in science and health and to invest in environmental protection and other infrastructure that will provide long-term economic benefits.
This project has attracted a good deal of attention, starting with the groundbreaking ceremony attended by dignitaries from the Kansas Department of Health and Environment, U.S. Environmental Protection Agency, Johnson County, and several media crews from local newspapers and TV stations.
J&N Utilities, Inc. has been awarded the sewer construction portion of this project and Electrical Associates LLC has been awarded the residential electrical portion. The Notice to Proceed for Construction of this project is scheduled for September 2015. Residents in this area can expect to see construction activities in association with this project for at least 18 months (September 2015 to March 2017). The contractors will contact all property owners connecting to sewers to notify them of the construction activities, as well as to schedule the required electrical work that will need to take place inside the house. The Notification of Contractors letter was mailed to all property owners in this district on August 17, 2015. This is the updated project cost sheet.
Following three requests for information meetings (the required number) by area residents, Johnson County Wastewater staff studied how this area might be best served by sanitary sewers, planned proposed sewers, and developed cost estimates. The project will serve approximately 85 acres and 352 properties around the Gardner Lake area with LPS. The proposed district consists of a residential neighborhood of 279 homes which are served by septic tanks. These sewers would provide service to all existing homes and vacant lots that could be developed in the proposed sewer district. The link above shows the proposed sewer district with the main lines.
The Kansas Department of Health and Environment (KDHE) administers a State Revolving Fund Loan Program (SRF) and has approved financing for this project. The program allows for a low interest loan from the state for a 20 year period to residents in the proposed district. It also calls for a 40 percent principal forgiveness (essentially, a grant) on the project. This program also offers financing for the installation of the grinder pump unit and connection fees for each home. Those properties that are “not assessed” will pay nothing. This color-coded map shows which properties are and which are not assessed.
A petition bearing signatures of owners of 57.9 percent (51 percent is the minimum required) of the land area in the proposed district requesting the installation of low pressure sewers was submitted to the County. A Public Hearing was held on Aug. 22, 2011. On Sept. 15, 2011, the Johnson County Board of Commissioners voted to approve the Gardner Lake Pressure Sewer Project. On March 8, 2012, the Board approved the KDHE SRF Loan Agreement for the project.
All construction phase work was completed in May 2013. Johnson County Wastewater will conduct post-construction flow monitoring, data analysis, and evaluation of the effectiveness of the completed construction through 2014. As part of the post-construction evaluation, Johnson County Wastewater is also evaluating the costs of numerous infiltration and inflow (I/)I removal strategies and will then determine how best to achieve I/I removal in the remaining watershed areas. Ultimately, Johnson County Wastewater's concern is to provide more dependable, cost-effective, and environmentally sound wastewater service to our customers. Please call Johnson County Wastewater's Project Manager at 913-715-8544 with any questions.
Sanitary sewer system performance within two watersheds, Mission Township Main (MTM1) - located in Prairie Village and Shawnee Mission Turkey Creek (SMTC) - located in Shawnee, is impacted by the magnitude of wet weather flows (I/I) that enter the sanitary sewer system through cracked or broken pipes, root penetrations, illicit connections, and other deficiencies within the system. The wet weather flows are also the result of illicit connections. This pilot study is needed to fill a critical gap in the data that exists relative to the system improvements necessary to adequately manage I/I, and in so doing meet both customer service goals and respond to evolving regulatory requirements established by the Environmental Protection Agency (EPA). The project included the construction phase which involved repair of the sanitary sewer system to remove I/I.
Lessons learned from the study and construction phases of this project will be used to develop the process and procedures for future removal of public and private sector I/I sources throughout the entire MTM1 and SMTC watersheds.
The Pilot I/I Project was initiated in March 2009 as a result of ongoing efforts by Johnson County Wastewater to effectively manage wet weather flows in the Nelson service area and is part of the most recent permit renewal process for the Nelson Treatment Complex. The study phase was completed in April 2010. The study involved a series of inspections, including televising of sewer lines and house service laterals, visually inspecting homes and businesses (including internal basement plumbing), manhole inspections, smoke testing, and various other inspections. The project took place in three (3) selected areas suspected of having high I/I:
(Shawnee - Vicinity of Quivira Road from Johnson Drive to 50th Street)
(Prairie Village - Vicinity of Roe Avenue from 75th Street to 79th Street)
(Lee Boulevard to State Line Road and 80th Street to 87th Street)
The construction activities on this project included rehabilitation and repair of existing sanitary sewer mains and private service lines, and disconnection of sources within buildings and on private property. Construction was completed in May 2013. The two links above to the project study maps show not only pilot I/I rehabilitation areas, but also where the strategies listed below were used:
This project included three (3) general types of construction:
-A Public Hearing regarding a Special Assessment for Lateral Sewer District No. 2 of Little Bull Creek No. 1 was held July 23.
The method of assessment for this district is the Per Homesite Method. This method recognizes the equal benefit to each homesite and apportions costs equally. All 65 homesites within Lateral Serwer District No. 2 of Little Bull Creek No. 1 will pay an equal share of the pressure main costs and the 56 homes that had pumps installed by this project will in addition pay equally for the pump system costs.
Any questions about this project should be directed to Johnson County Wastewater's Senior Engineering Technician at 913-715-8556.
Following several requests for information meetings by area residents, Johnson County Wastewater staff studied how this area might be best served by sanitary sewers, planned proposed sewers and developed cost estimates. The project will serve approximately 38 acres and 63 properties with low pressure sewers, including all existing homes and any vacant lot that could be developed in the sewer district.

Johnson County is a community that is thriving both socially and economically. This continued prosperity is strengthened by having reliable and sustainable wastewater networks with the capacity to support the community. Johnson County Wastewater's Engineering Group manages sewer design and construction projects throughout the County. These improvements are being built so that we can continue to provide you, our customers, with reliable sanitary sewer service.
Johnson County Wastewater does all it can to minimize the impact of sanitary sewer construction on people who live and work in the project areas. Sometimes this work goes unnoticed because it often takes place underground. But occasionally work must be done in streets or alleys near homes or businesses. We take care to reduce noise, dust, traffic, and any other potential construction nuisance to a minimum. We also meet with and mail updates to impacted neighbors before and during construction to get their input and provide them with progress reports.
The traditional method for enlarging Johnson County Wastewater’s sewer service area is to petition to add the described land to the Consolidated Main Sewer District (CMSD). The enlargement process is described in the link below. Publically-financed main sewers do not serve every parcel of land within a watershed, but provide the backbone of the sewer system. Branch lines which extend from these publically-financed main sewers are privately financed by the property owners.

Contract District Brochure explains the costs and process of creating a Contracy District within the Johnson County Wastewater Service Area for sanitary sewers.
The Tomahawk Creek Wastewater Treatment Facility, located at 10701 Lee Boulevard in Leawood, was originally built in 1955. The facility treats wastewater from the Tomahawk Creek watershed, the Indian Creek watershed downstream of the Douglas L. Smith Middle Basin WWTF (Lower Indian Creek), and the Dykes Branch sub-watershed. It currently treats 7 million gallons per day, which is 40 percent of the wastewater collected from parts of Leawood, Olathe, Overland Park, and Prairie Village. The remaining 60 percent is currently sent to Kansas City, Mo., for treatment.
Johnson County Wastewater is currently proceeding with the detailed design of the improvements recommended in the Preliminary Design Report, prepared during the project definition phase. It is anticipated that the project will utilize an alternate delivery construction approach. Award of the construction contract will occur in mid-2018, following the Kansas Department of Health and Environment's approval of final design documents. Work at the treatment facility is expected to be completed by the end of 2021.
The public will be updated throughout the entire process. Your input will be important as decisions are made, so please participate in future public meetings as well as continue to monitor this webpage for project updates.
The Project Definition Phase of the expansion was recently completed and focused on the following tasks: refining the previously recommended improvements, project costs, and schedule; developing a conceptual level site plan to support public outreach efforts and site permitting; and negotiating and finalizing a discharge permit for the new facilities. The results of this effort are summarized in the Preliminary Design Report.
Several studies were prepared to determine the future of the Tomahawk Creek Wastewater Treatment Facility. The Pre-Design Study evaluated various treatment alternatives and capacity scenarios using the latest user rate information and regulatory perspectives. The study identified $280 million in investments to expand the facility to 19 MGD as the most beneficial alternative.

The project team has completed several public outreach meetings, including a presentation to the Leawood City Council on Feb. 1, 2016, and a public meeting on Mar. 22, 2016. A recommendation for the design phase of the project was presented to the Johnson County Board of County Commissioners (BOCC) on Mar. 31, 2016. At that time the BOCC directed JCW to execute the regulatory permit for the project and to bring forward an authorization for design of the recommended improvements. At its regular meeting on May 5, 2016, the Johnson County Board of County Commissioners unanimously approved authorization of funding for the design phase of the Tomahawk Creek Wastewater Treatment Facility expansion and upgrade. If you have any questions regarding the project, please contact Lori Sand, Johnson County Wastewater's Director of Communications at 913-715-8572.
In the past, some Johnson County homeowners have faced the frustrating challenge of basement flooding during extremely heavy rains. There are several common causes for wet basements. Because Johnson County Wastewater wants to help you better protect your home during these rains, a Backup Prevention Program is available to homeowners. This program is voluntary and provides funding to eligible homeowners so they may install a backup prevention device or make plumbing modifications on their property.
There are many options available under this program. A contractor and Johnson County Wastewater will work with you to determine the option that offers the best solution for your property. Since the plumbing system in each home is unique, a contractor must inspect and determine the best solution to protect your property from future sewer backup. This may include a combination of options recommended by Johnson County Wastewater and the contractor.
This program is intended to help protect your home from future backups during heavy rains. However, a backup device or these plumbing modifications will not resolve basement water problems caused by cracks in walls, floors, window well leakage, and surface water flooding.
Johnson County Wastewater serves most cities in Johnson County. Only residents served by Johnson County Wastewater are eligible for this assistance.To be eligible for the program, your home must have experienced a confirmed sanitary sewer basement backup as a result of an intense rain event. The backup must have been the direct result of capacity problems in the sanitary sewer system. Johnson County Wastewater willl be responsible for confirming whether you are a qualified homeowner and will determine eligibility through the following process:
A Johnson County Wastewater representative is available to meet with you and your contractor to discuss all options in deciding the best possible solution for your property.
Backup Prevention Valve
A contractor may recommend installation of a backup prevention valve on the sanitary sewer service line just before it exits your house. This will require that a small portion of the basement floor be removed and the service line exposed for installation of the valve. Due to the regular maintenance required by the valve, Johnson County Wastewater recommends that the valve be installed in a location which is easily accessible on a regular basis.
Sewage Ejector Pump
A contractor may recommend a sewage ejector pump as an alternate to a backup prevention valve when floor and laundry drains are the only basement plumbing fixtures. Sewage ejector pumps are located in the basement and the drain lines from floor drains and sinks are connected to its basin. The pump located inside the basin has a float system that when activated will move solids and liquids to a higher elevation before it enters the home's sanitary plumbing again.
Johnson County Wastewater's list of contractors is for your convenience only. Contractors placed on the list have confirmed interest in this program and have attended an informational meeting on the Backup Prevention Program. Property owners are not obligated to employ a contractor on the list, and have the right to obtain a bid from any contractor.
Contractors performing work under this program shall maintain commercial general liability, including completed Operations coverage with a minimum limit of $500,000 combined single limit property damage and bodily injury liability, and Worker's Compensation coverage, if required by the State of Kansas or Missouri, depending on the place of business. Missouri contractors who maintain Worker's Compensation coverage shall have an "All States" endorsement included on their coverage.
Johnson County Wastewater does not endorse or recommend contractors for the purpose of installing backup prevention devices or the installation of sewage ejector pump systems. Any contractor who generates numerous complaints from property owners or neglects to perform quality workmanship shall be removed from the list at the discretion of Johnson County Wastewater.
Johnson County Wastewater
Since 1984, Johnson County Wastewater has spent in excess of $84 million to reduce the number of wet weather-related backups into homes and businesses. During this time, Johnson County Wastewater has reduced the number of annual wet weather sewer backups from more than 1,000 in the early 1980s to about 20 today. While the department has made great progress in this area, there are remaining problem areas where solutions have been more difficult to implement. As the department continues to study these difficult areas, property owners are encouraged to perform annual checks on the backwater valve to ensure that it is operating properly. This is particularly important prior to the spring storm season. This link will provide information regarding the operation and maintenance requirements of a typical backwater valve. Any maintenance, repair, or replacement costs associated with the backup prevention valve or any modifications of the plumbing shall be the responsibility of the property owner following the one (1) year warranty period.
