The Highland Tank passive grease interceptors prevent the discharge of fat, oil and grease into the sanitary sewer system and aid in the prevention of sanitary sewer blockages to protect the sewer system from sanitary sewer overflows.

The ‘diffusion and switchback baffling system’ of the Highland Tank passive grease interceptor retains wastewater long enough to allow liquefied grease to cool down, separate and congeal and allow for solid material to settle. They are available in large volumes to accommodate specified retention times, even 30 minutes or greater.

Aboveground rectangular or cylindrical interceptors and made-to-order designs are available so that you can customize volumes, compartments, inlets, outlets, or baffles to satisfy specific code requirements. Custom sampling ports are also available to aid in monitoring gravity discharge quality.
