How the Surface Water System Works
Consider the components of the project:
During high flow periods, the pumping stations follow a permitted withdrawal schedule to skim water from the Alafia and Hillsborough rivers and the Tampa Bypass Canal.
The Tampa Bypass Canal pipeline conveys water from the Tampa Bypass Canal pump station to the regional surface water treatment plant.
The South-Central Hillsborough Intertie (pipeline) conveys water from the Alafia River pumping station to the new regional surface water treatment plant. The South-Central Intertie also conveys water from the Alafia and Hillsborough rivers and the Tampa Bypass Canal to the C.W. Bill Young Regional Reservoir for storage. During dry times, this bi-directional pipeline carries water from the reservoir to the regional water treatment plant.
The first 66 million gallons per day (mgd) from the surface water sources will be processed at the regional surface water treatment plan for immediate distribution to Tampa Bay Water members. Any remaining permitted quantity (up to 200 mgd) could be set to the regional reservoir for storage.
During the dry season when river flows are low, little or no water is pumped at the Tampa Bypass Canal and the Alafia River pump station. Water stored in the reservoir is withdrawn to supply the surface water treatment plant during dry times. By collecting and storing water during high flow periods, we can meet the region's need for water year round without harming the environment, even during dry conditions.

Permits for these projects were required from many different agencies, including:
- United States Army Corps of Engineers
- Southwest Florida Water Management District
- Florida Department of Environmental Protection
- Hillsborough County Department of Health
- Hillsborough County Department of Planning and Growth Management
- Hillsborough County Environmental Protection Commission
- Tampa Port Authority
The total budget for the Alafia River, Tampa Bypass Canal/Hillsborough River High Water and South-Central Hillsborough Intertie is approximately $80 million. The project is jointly funded by Tampa Bay Water and the Southwest Florida Water Management District through the Partnership Agreement. That agreement earmarks $183 million from SWFWMD for development of eligible alternative water supply projects.
