Lift station replacement a subterranean project

While construction in the Orlando area has a very above-ground feel, there are projects going on in its subterranean reaches to support what's already here and what is to come.
An example is the lift station that the city of Orlando is preparing to replace at 1200 Lake Shore Dr. Known as Lift Station No. 3, the facility, which handles waste water through a pumping system, has reached the end of its 60 years of service.

Public works projects like the lift station allow maintenance of existing communities and commercial developments and take some of the burden off of what is being built, acting to complement Orlando’s expansion.
The projects aren’t cheap, especially in the case of Lift Station No. 3. So far, Wharton-Smith Construction Group of Sanford is the low bidder for the project at $3.8 million.

The bid will be reviewed by the City Council in September. If Wharton-Smith is approved, then a contract will be negotiated, said city spokeswoman Cassandra Anne Lafser.
Lift Station No. 3 serves the area around Florida Hospital Orlando, the Mills Avenue and Colonial Boulevard area and the neighborhoods of eastern College Park, Loch Haven Park and Rose Isle.

The city expects construction to begin sometime in the last quarter, but not before it holds a community meeting, Lafser said. The contract period is 365 calendar days.

Planned are design, permitting, bidding and construction services for mechanical, electrical and structural improvements to the lift station.

Improvements include conversion of the station from a wet well/dry pit configuration to a submersible lift station.

Specific design features include a new concrete wet well to accommodate four new submersible lift station pumps, an odor control system, a bridge crane system on an outdoor metal frame support to allow access to and lifting of pumps and motors and valves for on-site maintenance.
The station will also receive new gravity sewer lines and manholes connecting the existing gravity sewer lines to the new wet well, pump discharge piping, valves, a flow meter and a new 24-inch diameter force main to replace the existing 20-inch diameter discharge force main from the new lift station.
There will be a new electrical building with an emergency power generation system room, electrical and controls systems, site work for the new lift station, including new perimeter wall, landscaping, and a modified irrigation system.
Plans also call for a cantilevered access gate, paving, storm water drainage and demolition of the lift station after completing and commissioning the new one.
