Questions and Answers
This project has been designed to minimize noise to the public and will be in compliance with the City of Leawood’s noise ordinance.
The potential sources of noise will be the pumps and the blower motor for the odor control system carbon scrubber. The pumps will be located below water in the wet well (approximately 25-30 ft below grade) and would only be heard if you were listening right at the hatches above the pumps. The blower motor for the odor control fan will be located in a sound dampening enclosure that will be within the walls of the pump station.
Below is an excerpt from the City of Leawood’s noise ordinance (Article 2, Section 16-2-9.1):
“No use shall create noise in excess of that of normal daily traffic measured at the lot lines of the premises. In no case shall the noise level exceed 60 dB at repeated intervals or for a sustained length of time, measured at any point along the property line.”
Please refer to Slide 9 of the March 10 Presentation. As shown, the pump station is 60 ft from the south edge of College Blvd and 70 ft north and west of the comfort station. We plan to plant trees, which along with the existing trees, are intended to screen the view from the south and west. Please refer to Slide 14, which is a rendering looking southwest from College Blvd towards the pump station.
Locating the pump station north of College Blvd in the City Park was considered but was ruled out since that entire area is in the Indian Creek floodplain. It was determined that flood proofing the station and providing access to the pump station with respect to the 100-year flood, combined with the increased cost and resulting depth to reconfigure the sewers in the area, makes this alternative location cost prohibitive. There were really no other possible alternatives in that the station needs to be in close proximity to where the existing sewers converge, which is what led us to select the proposed site.
JCW does have several pump stations in residential areas. These include:
• 75th & Nall Excess Flow Station at 75th Street and Nall Avenue.
• Brush Creek Pump Station at 74th Street and Roe Avenue.
• Belinder Pump Station at Belinder Road and State Park Road.
• Granthurst Pump Station at State Line Road and Arno Road.
• Roe Village Pump Station at Skyline Drive west of Roe Avenue.
• 55th Street Pump Station at 55th Street and Alden Street.
JCW does have the power of eminent domain, however, prefers to pursue win-win situations with property owners where acquisition is required.
The actual number of trees removed will be determined during final design. Based upon the conceptual design we anticipate planting 90 trees of 2.5-in caliper (trunk thickness), as required by the City’s Development Ordinance. These trees will be located to maximize screening of the pump station from the surrounding area, especially the view from the golf course. The figures below show the tree removal plan as well as two renderings of the pump station with new trees re-established for screening. Slide 10 from the March 10 Presentation also includes a list of trees that would be added.

With any JCW project we keep odors in mind and know that this is a priority issue for neighbors. The best odor control technologies available will be incorporated into the pump station. Liquid chemical treatment will be provided at the site to inhibit the formation of odors in the forcemain. Vapor phase carbon scrubber treatment will be utilized to pull air from the pump station wet well and force that air through activated carbon, before releasing it to the atmosphere. The activated carbon media will be inspected/monitored routinely and will be replaced on an as needed basis to ensure it functions as intended. Further, it is important to note that the retention time of wastewater in the pump station will be less than typical. Less retention time means less odor potential.
Activated carbon is a very effective and reliable odor control technology, and if the fan is running, the system works very well. Mechanical failure of the fan would be the only reason why the odor control system would fail to adequately treat the air. JCW standard practice is to monitor the blower motor of the carbon scrubber and chemical feed pumps through their remote monitoring Supervisory Control and Data Acquisition (SCADA) system. If one of these devices fails, an alarm is triggered and JCW staff will visit the site as soon as possible to address the issue. In addition, JCW has a hotline for residents to inform JCW of odor concerns. A ticket is created, and a crew will be sent to the site within 24 hours to address the issue. The hotline can be accessed at (913) 715-8600.
The capacities are as follows:
• 8900 State Line Road Pump Station – 5.0 Million Gallons per Day (MGD)
• 103rd and State Line Pump Station – 1.8 MGD
• Hallbrook Pump Station – 0.4 MGD
The facility is designed for an average daily flow of 19.0 Million Gallons per Day (MGD)
It was permitted to treat 10.0 MGD but could only treat 4.0 – 6.0 MGD due to the outdated technology.
The forcemain will cross the trail at 4 or 5 locations. Brief closures, a matter of a few days (up to a week), are likely, although the details have not been worked out yet. In most cases, a localized short detour would be provided. These details will be finalized during detailed design of the improvements.
