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
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
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.
