Landmark Construction is one of the leading utility contractors in South Carolina. Our in-house experts perform all aspects of utility construction including sanitary sewer, force main, sewage pumping stations, water line installation, and stormwater management.

Sanitary sewers are complex systems of underground pipes that carry sewage, gray water, or industrial wastewater from buildings to the wastewater treatment plant. These sewers are part of a larger sewage system and are kept separate from storm sewers and combined sewers to avoid combined sewer overflow.
Storm sewer systems are important to help prevent flooding. They are designed to carry rainfall runoff and other drainages through underground pipes or open ditches and discharges into streams or other surface water bodies.
Electrical duct banks are groups of conduits that consolidate and protect cables running to and from buildings. Data and electrical cables are run through PVC pipes, bundled, and encased in concrete. These banks are then buried so the wiring for the commercial buildings is consolidated into central underground paths.
Water Line Installation
Water lines run underground to provide potable water to buildings. Our expert engineers will determine how water lines should be run to the site to be compliant with regulations, codes, and ordinances. We take into consideration pipe bedding, frost line, and thermal expansion.
When gravity flow isn’t enough to carry water and sewage through a gravity sewage line, a force main is used to move wastewater under pressure via compressors or pumps housed in lift stations. The system is designed so that the pressure of water entering pipes combined with the pressure from gravity-fed pipes won’t allow backflow.
Sewage Pumping Stations
Sewage Pumping Stations move wastewater to higher elevations to allow it to move distances by force of gravity. Sewage is first stored underground in a wet well, then pumped through pipes to a gravity manhole, until it is moved by gravity to a treatment plant.
