Reservoir and water tr​eatment facility project​

​The Toho Water Reservoir Project will provide an additional sustainable water supply for Toho Water Authority (Toho) customers in Osceola County. Once completed, the 400-million-gallon reservoir will capture and store excess water flowing into Lake Toho and collect stormwater. Up to 6 million gallons of water per day will be treated onsite to meet irrigation needs in the area and possibly even meet future drinking water needs.   


  • Provide an environmentally friendly water supply that helps reduce demand on traditional groundwater resources
  • Help with flood control
  • Treat stormwater to remove nitrogen and phosphorus entering Lake Toho and downstream rivers and lakes - this can help reduce algae blooms in our waterways
  • Access to recreational areas, such as trails and bike paths, along the reservoir





  1. Design Phase - Spring 2021 – Fall 2022 
  2. Construction Phase - Spring 2023 – Summer 2024 
  3. Treatment Facility Operations  - Starting Summer 2024



Treatment Facility ​Design and Construction Phases 

  • Activities are expected to be conducted during weekday daylight hours from 7 a.m. to 5 p.m. Every effort will be made to minimize activities outside of this time period.​ Community notifications will be issued should they occur.
  • Noise during the design is expected to be limited. In the construction phase, heavy equipment and noise associated with typical construction activities are expected to occur during weekday daylight hours from 7 a.m. to 5 p.m. 

Treatment Facility Operations

  • Facility will be operational at​ all times. Site visits by Toho staff will generally occur during daylight hours from 7 a.m. to 5 p.m. ​Some maintenance activities, when necessary, may require after-hour or weekend work.
  • Periodic deliveries of water treatment supplies and removal of byproducts (primarily sediment removed during water treatment).
  • Facility design will incorporate​, as much as possible,​​ ​​features that minimize noise associated with equipment operations such as pumps.
  • Treatment system is not expected to create offensive odors.
  • No sewage will be processed at the site.


Routine communication with neighbors will occur regarding project activities. An assigned Toho project representative will also be available for any inquiries.



We want to be a good neighbor and value your feedback or any questions you may have. Toho will be organizing community meetings to discuss the project. Please send any questions or feedback to  or use the submission form found on this page.
