Greenwood Lakes Plant Clarifier Rehab Starts Feb. 2; Nearby Odors Possible

Seminole County Utilities will temporarily take the clarifier at the Greenwood Lakes Water Reclamation Facility out of service beginning Feb. 2, 2026, to perform a rehabilitation project that will help maintain reliable wastewater treatment for homes and businesses served by the plant. The facility is located at 701-705 Green Way Blvd in Lake Mary.

The clarifier is a central tank in the treatment process that allows solids to settle before further treatment and discharge. During the rehabilitation, the clarifier will be removed from active service for maintenance work expected to last up to 30 days. Seminole County Utilities warned that neighborhoods within about a half-mile of the facility may experience intermittent odors while the work is underway.

Short-term odor impacts are the primary local consequence. Residents near Greenwood Lakes can expect occasional noticeable smells at times but should not expect service interruptions for sewer collection in homes and businesses. The facility continues to process sanitary sewer flows while the clarifier is offline, with the rehabilitation intended to prevent more significant outages or performance issues in the future.

This maintenance is part of routine infrastructure stewardship that affects regulatory compliance, operational reliability, and downstream water quality. Keeping major components such as clarifiers in good repair reduces the risk of emergency repairs and service disruptions that can be costlier and more disruptive to the community. For Seminole County, timely upkeep of wastewater assets supports long-term system resilience as population and development patterns change in Lake Mary and surrounding areas.

Seminole County Utilities has provided a contact line for residents with questions or concerns. Residents should call Utilities Engineering at 407-665-2024 for information, to report persistent odor impacts, or to get updates on the schedule. Providing a single point of contact helps the county track localized issues and respond where repairs or adjustments are needed during the rehabilitation period.

For nearby neighborhoods, the trade-off is a brief period of possible nuisance odors in exchange for restored capacity and reliability at the Greenwood Lakes plant. If the project begins as scheduled on Feb. 2 and runs the maximum 30 days, the work could conclude in early March. County officials will monitor conditions and adjust operations as needed to minimize community impacts while the clarifier is out of service.
