PJ Land Clearing & Excavating, Inc. is in good standing with Lake Worth and has performed very well on this contract according to Lake Worth staff.  The Riviera Beach Water Treatment Plant has a current stock pile of lime sludge that should be removed as quickly as possible to allow for continuing operation.  Once the stock pile is removed, this will allow for a more efficient operation of the storage yard.  The two existing “save all” basins are also used for lime sludge storage and backwashing.  These two basins will also be cleared by PJ Land Clearing & Excavation, Inc. on a regular basis.

The two basins are used to backwash the water treatment plant softeners.  The lime sludge settles in the two basins and then the solids are removed by mechanical equipment and loaders.  The solids are stock piled on the ground at the north end of the water plant property.  The lime sludge solid then dewaters over time.  In past years, this dried lime sludge was hauled away by road contractors to be used and mixed with road base.

The use of lime sludge as an admixture to roadway bases was disallowed by the Florida Department of Transportation approximately 8 years ago.  Due to this change, contractors no longer came to the City’s Water Treatment Plant to haul away the existing lime sludge.  Therefore, a stock pile of material has occurred and has to be hauled away on a contract basis.  Utility District staff contacted neighboring Water Treatment Plants to determine the most economical way to dispose of lime sludge.  The two most similar plants to the Riviera Beach Plant are Seacoast’s Richard Road Plant and the City of Lake Worth’s Water Treatment Plant.  The contractors for both of those plants were contacted by Utility District staff.  Both contractors visited the Riviera Beach Plant.  PJ Land Clearing & Excavation, Inc. was selected based upon the level of service provided and the economical pricing they offered.
