The Florida Department of Environmental Protection’s Office of Wastewater Management is responsible for permitting, compliance, and enforcement of Florida’s regulations for wastewater treatment plants. Ensuring that these plants properly dispose of the billions of gallons of wastewater produced daily in Florida is vital to sensitive estuary, bay, river, stream, and wetland ecosystems.
Unfortunately, wastewater treatment plants that function properly under normal conditions may be overwhelmed by the increased volume of water that infiltrates sanitary sewers during severe storm events. Under these conditions, raw sewage is released directly into the receiving body of water. Such dangerous sanitary sewer spills require a quick response to limit harm to human and environmental health.
Project Scope: The Kaizen event looked at the entire timeline of an overflow event, starting from the moment an emergency spill is reported through the completion of the response and receipt of paperwork from the wastewater treatment plant.
Project Team: 12 team members, including a champion and a team leader.
Facilitators: 4 facilitators-in-training from the Jacksonville Lean Consortium.
Goals: Standardize response process, identify a location for needed rapid response equipment, shorten response time by 50%, and decrease the number of steps in the process.
First, the participants engaged in a mock emergency event, which allowed them to map the current emergency response process. Next, the participants identified and eliminated steps in the process that did not add value to the response time or the quality of the response. Once the future response process was mapped, including all the suggested improvements, the process was accepted as a new standard operating procedure (SOP). Recommendations identified and implemented during the Kaizen event include:
- An SOP to perpetuate the new, improved process.
- A flow chart to assist staff in learning and implementing the new, standardized process.
- A phone number dedicated for emergency response, ensuring that calls get through immediately.
- A receptionist trained to answer the dedicated emergency response phone line.
- An “on-call” rotation so that on a given day, everyone knows who will respond if an emergency occurs.
- Car response kits to ensure no time is wasted looking for necessary items during the emergency.
- Standard forms for customers and outreach. These pre-addressed forms make facilities aware of their responsibilities and include questions responders should ask, directions for securing site, and other helpful information. All facilities need to do is add a stamp and mail it back.
- An updated data entry system.
- A public outreach plan.
|The improved process allows responders to help treatment plants secure and clean up the site of the spill sooner, reducing harm to people and the environment. This time reduction also represents a significant cost savings for the Office of Wastewater Management. In addition to reducing response time, the spill response checklist and form increased consistency and timeliness of facility responses. The tools and processes developed during this Kaizen event could also be applied in other areas of the Florida Department of Environmental Protection to improve compliance and decrease response time.|
Time Saved: 71 minutes per response (28% decrease), adding up to 54 hours per year.
Environmental: Securing and cleaning up spill site can begin more than an hour sooner; vital time in an environmental emergency.
Cost Savings: $32,800 per year
