Septic Tanks
Septic Tanks
Structurally sound and watertight, precast concrete on-site wastewater systems outperform and outlast systems comprised of other materials. Our septic tanks are designed to withstand loads that other materials cannot bear, and when routinely serviced, will provide many decades of trouble-free service. Special sized units are also available upon request. Our concrete tanks are designed to ensure strength and compliance with engineering specifications and environmental standards.
Pump Tanks
LarKen Pump Tank
Pump tanks, in conjunction with a septic tank and an effluent pump package, are designed to be utilized where a normal gravity system will not work. LarKen provides several sizes of pump tanks and pump packages that are customized to fit your system requirements.

Sand Oil Traps and Grease Interceptors
Sand Oil Traps and Grease Interceptors
These treatment tanks are designed to intercept and collect sand, grit, free oil, and grease (hydrocarbons and other petroleum products) in a wastewater flow and prevent their entry into the sanitary sewer system.
Catch Basins
LarKen Catch Basin
Catch basins are the main component in a landscape drainage system. LarKen offers them in various sizes. These are placed in the ground near areas of standing water to help facilitate proper water drainage and avoid property damage. The top of the box features a grate through which excess water and solids drain into the underground box.
Manholes (Risers, Bases, Eccentric Cones)
LarKen Manholes
Precast reinforced manholes have an unmatched reputation for its superior strength, durability, and hydraulics. Concrete is an inherently durable material. And unlike other structure types, concrete has increased strength over time. Precast concrete sets the standard for utility holes. A manhole will typically have a cast iron ring and cover on top allowing for access and provides durability to last through weather and traffic for decades before requiring replacement.
