Item K1BOARD OF COUNTY COMMISSIONERS AGENDA ITEM SUMMARY Meeting Date: December 11, 2013 Division: Engineering & Public Works Bulk Item: Yes _ No X Department: Wastewater Staff Contact Person/Phone #: Wilson 453- 8797)_ AGENDA ITEM WORDING: Discussion and direction of whether the County will fund conversion from low pressure collection systems (aka grinder pumps) to gravity collection systems for any additional areas of the Cudj oe Regional wastewater collection system. ITEM BACKGROUND: The Cudj oe Regional Wastewater project team (FKAA & County Staff) continues to receive requests to convert areas designated to receive low pressure (grinder pump) service to gravity collection. FKAA will present a comprehensive review of the remaining areas to be served by low pressure systems with a cost estimate should additional areas be converted. PREVIOUS RELEVANT BOCC ACTION: On October 16, 2013, the BOCC approved conversion of a number of neighborhoods including Buttonwood and Allamanda Drives on Lower Sugarloaf, Loggerhead Lane of Upper Sugarloaf, several streets in Cudj oe Gardens and Cudj oe Shores; and portions of Eden Pines, Doctors Arm; Big Pine North, and Big Pine South neighborhoods. The quoted cost of those conversions was $10.1 million. In July 2013 the BOCC approved a $122,010 expansion of the service area to include six properties on Upper Sugarloaf using low pressure technology. In January 2013 the BOCC approved adding 154 additional properties to the central service area using low pressure technology at a cost of $1.8 million.
