#3-Public Utilities BudgetFY11Public Utilities Budget
FY2011
August 3, 2010
Current FY Project Status
2001 Water Master Plan Status
Some recommended projects have been delayed due to reduced funding, but progress still being made. Since the 2001 Plan we have:
Interconnected the Buccaneer & Atlantic Beach Water Systems
Added a 300,000 gallon elevated storage tank at Water Plant #2
Replaced old cast iron water mains with new PVC mains in several areas of the City
Updated the Water Distribution System Model in 2007.
Water Capital Improvements for FY11
Replacement of old water mains on 11th from East Coast to Beach Ave. - $120,000
Rehabilitation of Well #1 at Water Plant #1 - $50,000
Water Plant Tank Rehabilitation - $55,000
Water Loss
Water loss is the difference between the gallons of water produced and the gallons of water billed.
Real Losses:
Water line breaks, leaks in joints or fittings (reported)
Background leakage
Water lost in treatment plant operation/maintenance
Authorized unmetered water use (fire fighting, hydrant flushing, water main disinfection, etc.)
Apparent Losses:
Meter inaccuracies
Billing data errors
Unauthorized water use (theft, contractors)
Water Loss Action Steps
Average water loss declined from a high of 20% in 1999 to a low of about 10% in 2006 but has been climbing since then. Action steps taken to reduce water loss:
Replacement of aging water mains and services
Professional leak detection on a portion of the system annually.
Annual testing and repair of all large meters (3” and up)
Replacement of old residential meters
Small Meter Replacement
Water meters slow down (read low) as they get older
Meter replacement program was in place, but will be enhanced beginning in FY11 – Additional $32,000
Additional 340 meters (562 total)
Approximately 7% of all meters and 10% of meters over 10 years old
Priority for replacement will be high use neighborhoods
2006 Sewer Master Plan Status
Sewer System Rehabilitation
Funding is less than recommended in Master Plan, but much has still been accomplished.
Royal Palms and Seaspray Subdivisions completed
Grant funding is allowing for completion of Salt Air area (currently underway) and Donner Subdivision
Additional sewer rehabilitation resumes in FY12
Sanitary Sewer Rehabilitation – Status at 2006 Sewer Master Plan
Sanitary Sewer Rehabilitation – Status FY 2010
TMDL – WWTP Improvements
Phaseout of Buccaneer and Upgrade of WWTP #1 – Current Status
Force main design complete, DEP permit received, prequalifying contractors
WWTP #1 Upgrade
60% Design and Constructability Review Complete
Equipment Pre-selection Complete
Energy Study underway
Odor Control Study underway
Sludge Study underway
Sludge Processing Study
Treated sludge is the byproduct of the wastewater treatment process. Our current treatment consists of:
Stabilization (aeration)
Dewatering on drying beds
Disposal at Trail Ridge Landfill
Hauling performed by City staff
No tipping fees per Interlocal Agreement with COJ
Sludge Drying Beds at WWTP #1
Preliminary Sludge Study Results
Modifications to the City’s sludge handling process are recommended.
Current system is antiquated, labor intensive, weather dependent and odor producing.
The new process for nitrogen removal will increase sludge production, putting the current system at maximum capacity.
If COJ enacts tipping fees, additional costs will be ˜ $131,000 (more with increased sludge volume). Mechanical dewatering will reduce tonnage and tipping costs.
Consolidation of aeration blowers could lower electrical costs.
