Wastewater Collections – Lift Stations #8 and #15 -
Engineering has commenced with the investigation and preliminary design of emergency diesel pumps that are to be installed at Lift Stations #8 and #15.  These diesel driven back-up pumps will automatically turn on in the event of a power outages and minimize wastewater staff having to physically respond to an emergency power outage.  In addition, the back-up pumps will be designed to handle above normal flows to the station during inclement weather, in an effort to minimize SSO’s.

WWTP Headworks Pump Station Rehabilitation –
This project consists of the removal of the five existing pumps, pump bases and associated ductile iron piping and installing five new pumps, pump bases and stainless steel (SS) piping.  Since all of the City’s raw sewage passes through the headworks pump station, the project required significant bypass pumping in order to perform the work. The bypass pumping system has been removed and site restoration is complete. All pumps and original ductile iron piping have been replaced.  New pumps and SS316 discharge piping are online and operational. A 24” valve was installed in the Raw water line to allow isolation and proper operation of the redundant pipe.

WWTP Flow Equalization Repair & Rehabilitation –
This project consists of the removal and replacement of the tank walkway supports, as well as repair and coating of the tank interior walls and piping. A PO was issued to TLC Diversified for the replacement of the tank walkway supports.  The current tank supports are aluminum and are severely corroded.  The new supports will be SS316, which is compatible with raw wastewater. A bid opening for the tank wall repair and coating will be held on January 22nd to address the cracks and spalls in the tank, and recoat the interior walls and piping to prevent future damage.

Water Treatment Plant – Design Build
The Water Treatment Plant (WTP) Refurbishment Project will rehabilitate / replace the existing 9.5 MGD treatment plant and ensure the ongoing production of high quality potable water to the City of Dunedin’s residents and customers.  The project is a progressive design build project and consists of two phases.  Phase I includes pilot testing and detailed design to 90% to establish a Guaranteed Maximum Price (GMP) for construction.  Phase II includes completing detailed design, construction, commissioning and turnover to the City.Phase I has commenced.  All full scale pilot systems have been delivered and startup is underway.  Pilot systems include:
 One (1) Dual Media Filter (DMF) Pilot
 One (1) Polymeric Ultrafiltration (UF) Pilot
 One (1) Ceramic UF Pilot
 Two (2) Reverse Osmosis testing Pilots
 One (1) Reverse Osmosis Membrane Screening Pilot
A sand – anthracite media was selected for testing in the media filtration pilot. Toray UF membranes were selected for the Polymeric UF and the RO membrane pilots. Nanostone was selected for the Ceramic UF pilot. Pilot units for media filtration, ultrafiltration, and reverse osmosis were delivered and will be plumbed and electrically connected to begin pilot testing. The next progress meeting will be held on January 17th and will address the testing plan and preliminary design.
