Toho Reservoir and Water Treatment Facility
Planning for the Future
The Toho Reservoir and Water Treatment Facility is a major collaborative effort between Toho and Osceola County designed to tackle three challenges at once: capturing stormwater to boost our irrigation supply, improving local water quality, and reducing the risk of flooding in the Judge Farms area.
Scheduled for completion in 2028, this state-of-the-art facility will be capable of pumping up to 16 million gallons of water per day to our community.
How It Works
- Dedicated Treatment: The new facility is built exclusively to treat water captured directly from the reservoir.
- Smart Water Reuse: Initially, this treated water will safely supply local irrigation needs.
- Future-Ready Design: We have built this facility with the future in mind, leaving room to expand its capabilities to supply clean drinking water down the road.
Water Supply and Benefits
The 400-million-gallon reservoir is permitted to provide 16 million gallons daily of water captured from storm and surface water to supplement Toho’s reclaimed water supply. It will also have a positive environmental impact: up to 25,500 pounds of Total Nitrogen and 2,700 pounds of Total Phosphorous will be removed annually from storm and surface water prior to discharge into Lake Toho, Lake Kissimmee, Lake Okeechobee and other environmentally sensitive water bodies. Having the reservoir protects and preserves our water resources.
Benefits at a glance
- Provide an environmentally friendly water supply
- Assist with flood control
- Reduce algae blooms in our waterways
- Provide recreational opportunities
Timelines
The water treatment facility will have three intake pump stations. These stations will pump water from the reservoir to the treatment facility. Please see the construction timelines below:
- Water treatment facility – Construction has not begun. Expected to be operational by end of 2028
- Idora Boulevard intake pump station – February 2026 and completed by first half of 2028 (See rendering: English / español)
- Mill Slough intake pump station – February 2026 and completed by end of 2028
- East City Ditch intake pump station – timeline to be determined
Please keep in mind, timelines are subject to change.
Common Questions
Expand AllThe water treatment facility will be located on the southern side of U.S. 192 near Fortune Road. The intake pump stations will be located off Idora Avenue, Mill Slough and East City Ditch. Please refer to the Toho Reservoir Map on this page for visual locations.
Water from the reservoir will help meet water supply needs for Osceola County. By capturing excess surface water, the project will help reduce demands on traditional groundwater supplies. The project also helps reduce nutrients contained in stormwater that can otherwise flow to downstream lakes and cause algae blooms.
Some lighting will be required. Lighting will be designed in a way to minimize impacts on the surrounding area.
The treatment facility and intake pump stations will include features to minimize noise and ensure that it complies with noise ordinances suitable for residential neighborhoods.
No. The facility will only treat water from the reservoir.
Since the facility will only treat water from the reservoir, we do not expect odors that may be associated with other types of water or wastewater treatment facilities. The intake pump station will only pump water from the reservoir to the water treatment facility. Odor is not anticipated.
While we have not completed designing the treatment process, we expect the following types of chemicals to be used:
- Polymer: non-hazardous substance that helps remove naturally occurring material in water by causing smaller particles to clump into larger clusters that can be removed.
- Disinfectant: a water treatment grade of liquid chlorine used to eliminate bacteria that might be present in the water.
No chemicals will be used at the intake pump stations.
All applicable environmental permits will be acquired. Harm to water resources or natural systems is not anticipated.
Like the other two stations, it will not be staffed 24/7. Toho staff will visit the station daily to check on equipment and collect samples for regulatory compliance and water quality monitoring. The station will primarily be monitored remotely. Toho staff will mainly use the new road off Neptune Road that will be built near the reservoir’s storm water berm. When needed, the station’s entrance on Idora Boulevard will be used.
