$77 million Western Trunk sewer line project begins in Lakeland, Fla.
The city of Lakeland, Florida, Water Utilities Department kicked off construction earlier this month for its largest infrastructure project to date, according to LkldNow. Construction crews have begun work to upgrade the Western Trunk Gravity Sewer line, which handles approximately 3.5 million gallons of wastewater per day.
The project will increase the wastewater line's capacity and realign sewer lines away from residential areas in Oakhill, Colonial and Citrus Center mobile home parks. This phase spans approximately 12,800 feet of linear feet of sewer main and 43 manhole covers, LkldNow reported. The work is projected to take around 20 months to complete.
The project will cost an estimated $77.7 million, more than quadruple the $17.8 million Lakeland spent to build the Northeast Water Treatment Facility on Old Combee Road over 20 years ago.
The Western Trunk Line is a gravity sewer that carries about 3.5 million gallons of wastewater a day, although that volume can swell to almost 20 million gallons after major rains.
The Western Trunk Line was built in the 1950s as a 36-inch, non-reinforced concrete pipeline. The new sewer line will be 42 inches in diameter.
Workers will have to dig trenches from 7 to 25 feet deep and install 43 manholes and about 12,800 linear ft of sewer main at precise downward angles so gravity can carry the waste.
According to Water Utilities Engineering Manager Robby Kniss, it is a generational project that should last for the next 100 years.
