There’s yet another major infrastructure project breaking ground this summer that will be a first for Manteca.

The first?

There are no road closures or detours involved.

The Manteca City Council on Tuesday award a $6.9 million bid to Teichert Construction to replace a segment of the aging central sewer trunk.

The city is replacing 4,200 feet of the Central Sewer Trunk Line that runs along the southern edge of the golf course between Union Road and a juncture where it turns south and heads under Airport Way to the treatment plant.
The line is where wastewater from much of Manteca north of the 120 Bypass is funneled through on the final leg of its journey to the treatment plant.

The aging line being replaced has been determined to be near the end of its useful life.

Segments of the trunk line have failed in the past 10 years including beneath Union Road from the southern edge of the golf course north to Lousie Avenue forcing emergency repairs. At one time, sewer flowed down the middle of Union Road in temporary above ground pipes while the failing segment was relined.

The latest work will also reduce the need for a pump station as the alignment for the new 36-inch pipe will be deeper to allow for gravity flow.

The sewer line being replaced is along the south side of the golf course by the No. 1 hole.

The new alignment departs from the golf course sooner offering significant cost savings, reduced construction time and minimizes golf course impacts.

By being able to flow by gravity, the replacement line will increase the overall capacity from 15 million gallons of water per day to 19 million gallons of water per day.

As such, it will help greatly reduce long-term operations and maintenance costs.

It is among first capital improvements the wastewater rate hike that went into effect two years will tackle.
