Question 1

Will the pump station emit an odor and, if so, how will it be controlled?

Accepted Answer

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.

Question 2

Will water service be impacted by the project?

Accepted Answer

We do not anticipate any impacts to water service in the area.  However, if a brief shut down is needed to make a tie in or for other reasons unknown at this time, it could be scheduled at night or at another time that doesn’t inconvenience the adjacent property owners.
