Action Requested

Approval of letter to the Peace River Manasota Regional Water Supply Authority (PRMRWSA) with revised water supply demands and supply needs from sources developed by the PRMRWSA beginning in the year 2036



Enabling/Regulating Authority

Federal/State law(s), administrative ruling(s), Manatee County Comprehensive Plan/Land Development Code, ordinances, resolutions, policy.

Comprehensive Plan establishes policies for continued coordination with the Peace River Manasota Regional Water Supply Authority. The Amended Interlocal Agreement creating the PRMRWSA established the County Policy to expect future water supply be coordinated with the Authority.  This policy has been reaffirmed by the establishment of the Water Planning Alliance, by Resolution R-01-183, and the Master Water Supply Contract (October 2005).



Background Discussion
  • February 1982 – BCC approved and executed the Interlocal Agreement creating the Peace River/Manasota Regional Water Supply Authority (PRMRWSA).
  • May 1991 – The BCC approved and executed the amended Interlocal Agreement creating the PRMRWSA, the Acquisition Agreement, and the Peace River Water Supply Contract.
  • August 14, 2001 - The BCC adopted Resolution R-01-183 setting forth terms and conditions for establishing the Water Planning Alliance and providing for Manatee County’s voluntary participation in the Water Planning Alliance.
  • September 20, 2005 -  The BCC approved the Master Water Supply Contract with the PRMRWSA which stipulates in Section 11 that each party requesting future water supply from the PRMRWSA must annually submit  by January 15th the party’s projected water demands for the next twenty years.
  • April 20, 2006 - The BCC approved submittal of projected demands and proposed schedule for Water Supply Development showing the PRMSRWSA delivering 5 mgd beginning in 2014 with deliveries potentially increasing to 20 mgd by 2030.
  • The 2007 population projections and estimated water demands resulted in a development schedule that called for the need for additional supply from the Authority in 2017 and reduced overall potential need to 10 mgd between 2017 and 2030.
  • Annual population and water demand projections provided by the Manatee County Planning staff in November 2008 and December 2009 reflected a prolonged effect of the economic situation resulting in further reductions in population growth and the subsequent need for additional supply.
  • In December 2011 Manatee County Planning staff provided updated population projections reflecting adjustments due to the inclusion of the 2010 census data. This resulted in a decrease of projected water demand of approximately 3 MGD per year, which further shifted the need for further water supply development or potential need of supply from the PRMRWSA until 2034.
  • In June 2016 SWFWMD issued a modification of the Manatee County consolidated water use permit to allow an additional 3.1 MGD withdrawal quantity at the East County Well Field as a conjunctive use. A Special Condition of that permit allows for 3.1 MGD to be converted to an increase in the total permit from 52.85 MGD to 55.95 MGD when demands justify the need. 
  • In December 2016 Manatee County Planning staff provided updated population projections which showed a slight increase in projected demands, but continued to suggest the need for additional water supply development or potential need of supply from the PRMRWSA will not be until 2036.
  • The 2016 population projections and estimated water demands indicate a need of additional supply of 5 mgd from the PRMRWSA in 2036. Dependent upon the results of the upcoming Minimum Flow determination for the Manatee River by the Southwest Florida Water Management District and the impending recovery strategy, the need for additional supply from the PRMRWSA may be accelerated. It is expected that the annual review of population and demand projections will allow sufficient time to adjust any implementation schedule for additional supply to offset that lost through the implementation of a Minimum Flow schedule.
