Grease interceptor technology is playing an increasingly important role in protecting wastewater infrastructure, as utilities and facilities look to manage fats, oils and grease (FOG) more effectively.
NWPX Infrastructure has highlighted its GreaseTrooper® gravity grease interceptor system as a solution designed to remove FOG from wastewater streams, helping reduce sewer blockages, overflows and long-term network degradation.
The systems are designed for use across a range of sectors, including food service, industrial processing and institutional facilities where FOG discharge can significantly impact sewer performance.
Grease interceptor technology improves FOG control in wastewater systems
Fats, oils and grease remain a major contributor to sewer blockages and overflows, particularly in urban environments with high concentrations of commercial kitchens and food processing operations.
Gravity grease interceptors operate by slowing wastewater flow and separating it into layers. Grease rises to the surface, solids settle at the base, and clarified water exits the system, reducing the volume of contaminants entering the sewer network.
This process helps utilities maintain system performance while lowering the risk of costly maintenance interventions and environmental incidents.
Flexible design for varied infrastructure requirements
The interceptor systems are available in a range of sizes and configurations to suit different operational needs, from smaller facilities to large-scale industrial sites.
Construction options include precast concrete, stainless steel and fibreglass, with installations designed for above-ground, buried or retrofit applications depending on site constraints.
Pre-engineered, pre-piped designs can also help streamline installation, reducing on-site labour requirements and minimising disruption during deployment.
Supporting proactive maintenance and long-term performance
Monitoring and maintenance are critical to ensuring effective FOG management. Systems can be equipped with remote monitoring technology that alerts operators when grease levels approach capacity, enabling timely servicing before performance is impacted.
By enabling more proactive maintenance, grease interceptor technology supports more efficient wastewater operations and helps extend the service life of sewer infrastructure.
As wastewater regulations continue to tighten globally, solutions that address FOG at source are expected to play a growing role in protecting water quality and improving network resilience.
