SAK Construction (SAK), a national pipeline rehabilitation and tunneling services contractor, is beginning work on $21.7 million of contracts won throughout the Baltimore and Washington, D.C. regions. SAK is repairing the sewer and pipeline infrastructure in these metropolitan areas without excavation or disruption by utilizing state-of-the-art trenchless technologies, including CIPP (cured-in-place pipe) pipeline rehabilitation.

SAK was awarded the following projects as low bidder:

  • District of Columbia Water and Sewer Authority:

  • G100: Local Sewer Rehabilitation 1: a $5.25 million contract for the rehabilitation of approximately 140 manholes and the replacement of existing sewer mains throughout the District of Columbia. Using CIPP, SAK will rehabilitate 15,000 lf of sanitary sewer pipeline, with diameters ranging from 12 to 24 in. The project is under way and will conclude in 2017.

  • Rehabilitation of Sewers Under Buildings Phase 2: a $3.6 million contract for the structural repair of sanitary sewer and combined sewer and storm water pipes under buildings at19 sites throughout the District of Columbia. SAK will use CIPP, shotcrete and other methods to repair pipes ranging from 10-in. diameter to 108-in. height.

  • Baltimore County

  • Herring Run Basin 31: a $2.04 million contract for the rehabilitation of sewer lines in the Ridgeleigh Community, also known as “The Oaks,” situated near Loch Raven Boulevard and Joppa Road.

These projects reflect strong national demand for pipeline rehabilitation resulting from America’s aging infrastructure. Collapsing, malfunctioning or inadequate water mains, sanitary sewers and storm sewers produce a variety of serious problems and threaten the water supply.

To address these needs, while minimizing above-ground disruption, municipalities are seeking solutions like those offered by SAK Construction to provide the newest underground trenchless technologies for pipeline rehabilitation. SAK also provides solutions for repairing drinking water mains from 6 to 16 inches in diameter. When expansion of existing water, sewer and storm water systems is required, SAK provides large diameter tunneling services for 48-in. diameter up to 32-ft arch-shaped.
