City of Hollywood Department of Public Utilities 4 CIP Projects (Priorities 1 and 2)
City of Hollywood Department of Public Utilities 5 Completed CIP Projects ■SRWWTP Building “A” HVAC rehabilitation – The project consisted of full replacement of main HVAC components for SRWWTP Building “A”. The project was substantially completed on December 2009 at a cost of $576,010. The contractor is working on final punch list items.
City of Hollywood Department of Public Utilities 6 Completed CIP Projects ■Injection Well Pump Station VFD Conversion – To obtain the operation flexibility for variable plant flow rate, Injection Well Pump No. 3 was converted to VFD. Completed in December 2009. The cost of the project was $185,000.
City of Hollywood Department of Public Utilities 7 On-going CIP Projects ■Oxygen Generation System Upgrade. Design-Build contract for approximately $10.4M. Current status approximately 60% complete. Completion date September 2010.
City of Hollywood Department of Public Utilities 8 On-going CIP Projects ■Continue Sewer Rehabilitation & Inflow/Infiltration reduction Program – This project is primarily addressing sewer collection basins H11, H15W and H31. Additional sewer basins (i.e. H-18 and H-12) were added as alternates. The program began on August 2009 with a cost of $6.7 M.
City of Hollywood Department of Public Utilities 9 On going CIP Projects ■Vacuum Truck Sump Upgrade – The purpose of this project is to upgrade and expand the existing vacuum truck sumps by adding sump areas, and by decreasing the existing floor elevations to maximize flow. The construction cost of the project is $224,000. Notice to Proceed was issued on February 2010; completion of the project is expected on May 2010.
City of Hollywood Department of Public Utilities 10 On-going CIP Projects ■Construct McKinley Street Parallel Interceptor – Bids for this project were received on January 8, 2010.

City of Hollywood Department of Public Utilities 11 Notable CIP Projects ■Grit Removal System Rehabilitation and Replacement: ●Estimated cost to replace existing system is approximately $19.5M. ●A proper working system is needed to remove grit from the wastewater to protect moving mechanical equipment from abrasion and abnormal wear, reduce conduit clogging, and prevent deposition in treatment basins. ●Existing system has severe sluice gate, weir and concrete deterioration; it also has poor removal efficiency, based on the accumulation of grit in the downstream facilities.

City of Hollywood Department of Public Utilities 13 Notable CIP Projects ■Bar Screens Rehabilitation and Repairs: ●Estimated cost of repairs is approximately $14M. ●Function of the bar screens is to remove large solid objects in the influent flow stream to protect downstream mechanical equipment. ●Severe deterioration has occurred in the concrete around both bar screens and in the bar screen chamber. ●Deficiency of screening facilities have resulted in rag build-up in the downstream process. ●The addition of a bypass to divert flow around the bar screens during repairs is included in the estimate. ●Immediate implementation of repairs recommended in the Master Plan.
