Description
The Regional Integrated Loop System project 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 four county region. The Phase II Interconnect project is a
component of the Regional Integrated Loop System that will provide needed regional transmission capacity between
the Peace River Facility and the City of North Port. The transmission line will be a 36-to-48 inch diameter pipeline
extending approximately 5.5 miles from the Peace River Facility, generally along the existing 36-inch regional
transmission main (RTM) corridor to Serris Boulevard, where it will interconnect with the City of North Port's
transmission/distribution system. In addition to serving the City of North Port, Phase II provides back-up capacity to the
existing 36-inch RTM, and comprises a critical segment for the extension of future regional transmission capacity to
the City of North Port's Myakkahatchee Creek Water Treatment Facility, the Englewood Water District treatment
facilities, and the Carlton Water Treatment Facility.
Benefits
The initial segment of the Phase 2 Interconnect will allow the City of North Port to receive additional water from the
Authority's ongoing expansion project. The City currently requires this project to transmit the quantities of water they
are contracted to purchase from the Authority in FY2012. Development of additional segments 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 (SWUCA); and better match supply, demand and financial investment on a regional
basis. The use of alternative sources with the maximization of surface water for public supply is consistent with the
District's Regional Water Supply Plan.
Costs
The total estimated cost for the H051 Phase 2 Interconnect is $15,400,000 with the requested District share being
$7,700,000. The District funding will be divided between the Governing Board, $3,850,000 (50%); Manasota Basin,
$2,810,00 (36.5%); and the Peace River Basin, $1,039,500 (13.5%). District funding in FY2010 is anticipated to be:
General fund $1,500,000; Manasota $500,000; Peace River $200,000; for a total of $2,200,000.
The Funding table below shows funds that were budgeted in "FY2007" and "FY2008" and "Cumulative Transfers".
Those funds lapsed at the end of their fiscal years, as the project was not pursued at those times. A negative
adjustment is made under "prior funding" to show the actual total funding.
The long-term project cost of all additional Phase 2 components for joining the Englewood Water District, City of
Venice, and the Carlton WTP has been estimated at $106,378,217.
Additional Information
The Loop Feasibility/Routing Study was authorized by the Authority in May 2005 and the report was issued in June
2006. 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.
The Study's recommended Phase 2 route connects the Peace River Water Treatment Plant with the Myakkahatchee
Creek Water Treatment Plant and then branches into two segments. The one segment loops northwest to Sarasota
County's Carlton Water Treatment Facility, and the other segment runs southwest and connects to the public water
systems of the Englewood Water District and the City of Venice.
In August 2007, the Authority Board approved the first work order for Phase 2 of the Regional Loop System and
issued a notice to proceed. In December 2007, the Authority's consultant released a preliminary design report for the
Phase 2. In May 2008, the Authority chose to postpone the project in favor of an alternate connection between North
Port's system near the Snover Waterway and the existing regional line connecting the Carlton and Peace River WTPs.
As a result, the District reallocated the FY2007 and FY2008 funds towards other projects.
After much discussion between the City of North Port, Sarasota County, and the Authority over shared capacities, the
Snover Waterway connection was considered insufficient to meet all the partners' combined needs. In November
2008, the Authority revised a shorter version the Phase 2 project, which calls for a segment between the Peace River
WTP and the North Port's Serris Blvd connection. The pipeline would be the length needed to deliver an increased
capacity to the City, but would retain the greater transmission capacity needed for future extensions. In February 2009,
