WWTP Denitrification Filter Building Repair & Rehabilitation –
This project consists of the removal and replacement of twenty (20) valves and actuators for the denitrification filters, removal and replacement of two pumps and 2 check valves, and repair of damaged concrete portions of the filter building.  To perform the work, insertion of eight line stops are required to isolate portions of existing piping and valves.  In addition, all piping corresponding to replaced valves will be painted. SGS Contracting Services was awarded the contract in the amount of $697,400 on April 19th; the Pre-Construction meeting was held on May 29th. Due to long lead times for the valves and actuators, the “NTP” was issued for August 20th; with project completion anticipated before June 12, 2019. To date, the Contractor has removed and replaced Backwash Pump #1, replaced the existing 16” check valve, modified the discharge elbow and has successfully started and run the new pump.  Wastewater staff has assisted in disconnecting electric conductors, tagging/lockout all electrical equipment and reconnecting the electric for startup.   Contractor is currently working on Backwash #2 and anticipates startup in the next several weeks.

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.  This is a Progressive Design-Build project which consists of two phases.  Phase I, included pilot testing (already completed) and detailed design to 90% in order to establish a Guaranteed Maximum Price (GMP) for construction.  Phase II, includes completing detailed design, construction, commissioning and turnover to the City. Phase I detailed design is currently underway.  The 90% design package was submitted mid-November, and is under review by the City and the City’s value engineering consultant, Tetra Tech.  The 90% design review meeting will be held on December 12th between the City, the City’s value engineering firm, and Black & Veatch. The 90% Design package is currently out to bid with bids due on January 18th.  Once the bids are reviewed, the City will receive the GMP, which will subsequently be brought before the Commission for consideration of construction award.

Lift Station 8 & 15 Emergency Diesel Pumps –
These Emergency Diesel Pumps will automatically turn on in the event of a power outage, thus minimizing the need for wastewater staff to physically access the stations to respond to an emergency power outage.  In addition, the back-up pumps are designed to handle above normal flows to the stations during inclement weather, in an effort to minimize SSO’s. The City’s consultant has completed the 100% Design Drawings and Specifications for the project.  The project will be advertised for Bid the week of December 12th with bids being due on or before January 8, 2019.
