Action Requested

Approval of letter to the Peace River/Manasota Regional Water Supply Authority with revised water supply demands and supply needs from sources developed by the PRMRWSA beginning in the year 2034.



Enabling/Regulating Authority

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 – The Board of County Commissioners approved and executed the Interlocal Agreement creating the Peace River/Manasota Regional Water Supply Authority (PRMRWSA).
  • February 1984 - A revised Interlocal Agreement was approved and executed by the Board.
  • May 1991 – The Board approved and executed the amended Interlocal Agreement creating the PRMRWSA, the Acquisition Agreement, and the Peace River Water Supply Contract.
  • August 14, 2001 - The Board approved 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.
  • August 31, 2004 – The Board conducted a workshop on the Update to the Manatee County Water Supply Plan.  This Plan required additional capacity to be incrementally added in 2010, 2014, and 2018. The opportunity for a regional alternative supply source should be available in either 2014 or 2018.
  • September 20, 2005 -  The Board approved the Master Water Supply Contract (MWSC) 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.
  • From 2006 to 2010, population projections were developed annually by the Manatee County Planning staff, and corresponding demand calculations were submitted to the PRMRWSA in accordance with the MWSC. Projected demands rose with the boom and fell with the economic effects of the ‘Great Recession,’ but the potential need for water or new water supply development for Manatee County from the PRMRWSA remained outside of the ‘7-year contractual window’ for developing new supplies.
  • For 2011 to 2013 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.
  • On August 4, 2014, Manatee County Planning Staff provided updated population projections which result in essentially unchanged (0.5%) demand projections through 2035. Water supply development or potential need of supply from the PRMRWSA will not occur until 2034.

The 2014 population projections and estimated water demands  result in essentially an unchanged schedule for the implementation of water supply options or the need for additional supply from the Peace River/Manasota Regional Water Supply Authority from those presented last year.  This implementation schedule includes the implementation of additional supply of 5 MGD from the PRMRWSA in 2034. 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.

The current 2015 submittal to the PRMRWSA will reflect current projections and estimated water demands, with notice that Minimum Flow results may affect future supply needs which may be reflected as early as our submittal for next year (2016).
