Description
The Regional Integrated Loop System Program is a series of transmission pipelines that will be developed to regionally
transfer and deliver water from existing and future alternative supplies to demand centers within the Peace
River/Manasota Regional Water Supply Authority's (Authority) four county region. This project, Phase 3A, proposes to
construct a pipeline from Sarasota County's Carlton Water Treatment Facility north across the Myakka River to an
existing County utility line. Eventually the interconnect will extend into Manatee County once all phases have been
completed.
Benefits
Development of this project will further integrate regional resources; maximize surface water for public supply; provide
rotational capacity and the ability to rest sources; provide for reserve capacity for emergency transfers; provide
alternatives to the development of groundwater in the Southern Water Use Caution Area; and better match supply,
demand and financial investment on a regional basis.
Costs
The total estimated cost for the Phase 3A project is $42,570,000, with the requested District's share
being $21,285,000. District funding will be divided by the Governing Board, $10,642,500 (50%); the Peace River Basin
Board, $2,873,475 (13.5%); and the Manasota Basin Board, $7,769,025 (36.5%.) The District funding in FY 2010 is:
Governing Board ($4,087,983), Peace River Basin Board ($0), and the Manasota Basin Board ($2,118,404) for a total
of $6,206,387. Total funding budgeted to date (FY2008 and FY2009) is $12,729,517, split between to Governing
Board ($6,554,517), the Peace River Basin Board ($1,709,750), and the Manasota Basin Board ($4,465,250)
Additional Information
This project would provide potable water service to areas of northern Sarasota County and Manatee County. Phase
3A is the initial segment in the overall Integrated Regional Loop System Phase 3. Subsequent expansions (Loop
System Phases 3B, 4A and 4B) include additional interconnect facilities in northern Sarasota County and southern
Manatee County, allowing regional water delivery service to those communities. Total cost for the entire Phase 3 &
4 program is estimated to be $146,207,442.
On April 2008, District staff received the Preliminary Engineering Basis of Design Report for Phases 3A and 3B. The
Feasibility/Routing Study identified the preferred loop pipeline routing, environmental impacts, major connection
points, preliminary pipe sizing, proposed schedule of project phasing, and time frames for construction. Major
components of Phase 3A include above ground storage, a pumping station and approximately nine miles of 48-inch
diameter transmission pipeline. The pipeline route is generally from the Carlton Water Treatment Plant westward
across the Myakka River following an established utility corridor; west along Laurel Road, north along Knights Trail
Road, and parallel along Cow Pen Slough to a point near the Central County Landfill and State Road 681.
Components co-located at the Carlton Water Treatment Plant would include a pumping station with a 10 mgd capacity
and above-ground storage. It is anticipated that a portion of the project's storage component, a 5 million gallon above
ground storage tank, will be acquired from Sarasota County by the Authority. The transmission capacity of the pipeline
will have a minimum design capacity of 37 mgd. Future upgrades to the pumping station will be needed to reach that
capacity. Phase 3A will provide an additional water delivery point to Sarasota County and the potential for an inter-tie
between the Authority's RTS and the City of Venice water system.
The Cooperative Funding Agreement between the District and the Authority for Phase 3A was executed on November
10, 2008. The Agreement is back-dated to July 25, 2007 and will remain in effect through November 1, 2011. . The
Interlocal Agreement between the Authority and Sarasota County was signed by the County on March 32, 2009 and by
the Authority on April 1, 2009.
The Authority submitted RAI responses for the FDEP ERP for the pipeline and the FDEP Myakka River Wild & Scenic
River Permit on May 8, 2009. Also on May 8, 2009, permit applications were submitted for the FDEP drinking water
permit for the pipeline and pump station, and for Sarasota County's Site & Development Permit.
On June 3, 2009, the Authority board approved a work order for final design services of a new 5 million gallon storage
tank to be located at the Carlton WTP.
