RE: Feasibility of Water Supply System Interconnection Within
the Tri-County Area
Attached is a conceptual plan for water system interconnect within the tri-
county region of Hillsborough, Pasco and Pinellas Counties. According to
studies conducted by private consultants, SWFWMD staff and local planning
agencies, there is plenty of water available to this region. Water shortages
have been or will be in the immediate future a result of inadequate facilities
and transport mechanisms to the area of water demand. Interconnection of all
water supply systems will maximize the use of existing sources and create the
potential of serving additional customers along the major transmission mains.
As mentioned, this is only a "conceptual" view of interconnect based solely on
benefiting water management functions. Items that would actually determine the
feasibility of interconnect, such as cost effectiveness, energy use, facility
compatibility, water (source) compatibility, hydrologic and environmental im-
pacts and long-term system reliability have not been considered. These items
and the final determination of the actual location of the interconnect would
best be evaluated by the engineers involved with the individual water systems.
District staff should continue their investigation on how to obtain interties
where needed and how to encourage interagency cooperation. This can be accom-
plished by establishing a strong District management philosophy based on our
understanding of current water system needs and sources. Caution should be
taken that the District continues to look at all long-term management tools;
interconnection is only one such method.
The District's part in maximizing the use of our existing water systems in
the tri-county area can be summarized as below. Please remember that this
is staff's first look at the feasibility of interconnection and further inves-
tigations should be made.
1. The District should strongly encourage interconnection of
water supply systems where shown to be a good management
tool and cost-effective.
2. The. WCRWSA should become more service oriented and provide
interties to its member governments plus other water sys-
tems within the tri-county region.
3. The membership of the WCRWSA should be expanded to include
representatives from all municipalities within its region.
4. The District should mandate interties as a service to other
municipalities. There are many independent water supply
systems that could benefit from an interconnection with a
reliable source and preclude the development of emergency
